    bodies comprise a box-like housing provided with four openings arranged on each of the four sides of the housing, and one or more damper doors arranged to rotate inside the housing to alternately direct the air flows between one of two openings to the heat-absorbing bodies. The device changes the path of an air fate by diverting the air flow substantially perpendicular to its previous fate direction ring. A disadvantage of this construction is that since the openings must necessarily be located one on each side of the housing due to the construction of the shutter doors, the ventilation ducts leading to the device will extend in different directions, so that it becomes difficult and expensive to install the device in a ventilation system, especially in an already existing ventilation system.
    US 7, 059, 385 shows another example of a ventilation device for alternating two air flows. The device comprises two heat-absorbing bodies arranged in parallel and provided with rectangular openings to allow an air flow therethrough. The openings are connected to two ventilation ducts so that each ventilation duct covers half of both openings. The device further comprises rotating the flectors arranged between the bodies and the ventilation ducts, and provided with two openings which each have an area of about a quarter of the surface area of the fl vectors.
    By rotating the 90ectors 90 degrees, the two öpport openings are moved to allow an air flow from only one of the ventilation ducts to each body, and thus the air flows can be exchanged through the bodies. A disadvantage of this device is that the air gap will mostly be concentrated to the half of the body that is open towards the ector opening.
    Thus, the efficiency of the device will decrease, especially since the vector openings will allow communication with different halves of the body for each respective air flow. Furthermore, since the air fates are intended to change approximately once every minute throughout the life of the device, the wear on the moving parts of the device is heavy, and it is both difficult and expensive to manufacture the disc-shaped ectectors which are resistant to fatigue.
    Another problem in this area is that huge volumes of air have to be expelled for large buildings, which requires ventilation ducts with a large cross-section. A ventilation device for alternating the vä pathways must therefore also be large with large and heavy damper doors or the flectors, which increases both the wear and the energy consumption for the rotation of the damper doors or the flectors. In particular, it is difficult to manufacture a large de-ector of the type in US 7,059,385 for large volumes of air.
    SUMMARY OF THE INVENTION A ventilation device for switching two airways between two objects of the present invention is to provide a heat absorbing body, which device is easy to install in a ventilation system.
    Another object of the present invention is to provide a ventilation device for exchanging two airways between two heat-absorbing bodies, which device has a large air capacity.
    These objects are achieved with the ventilation device according to the preamble of claim 1, characterized in that the ventilation device comprises at least a first air flow passage between the first and the second air flow channels arranged to direct at least a part of the first air flow from the first air flow channel into the second air flow channel. .
    Thus, it is possible to direct the first air flow from the first air flow channel, connected to the first body, and into the second air flow channel, connected to the second body, changing the path of the first air flow from passing through the first body to passing through the other body. Thus, instead of having to direct the air to a separate, box-smelling house fitted with shutters to change the path of air to different openings in the house, or having to provide an expensive de-ector at an interface between two ventilation ducts and two heat-absorbing bodies, the invention includes the air flow is led directly from the first air flow channel and into the second air flow channel.
    Thus, the device can be designed to be very compact and small relative to its capacity. Furthermore, since the air flow is led from one duct and further into the other duct, the size of the device can be close to the same order of magnitude of the two ventilation ducts' capacity. According to one embodiment, the openings of the air ducts as those with the same leading to the heat-absorbing bodies are designed to fit the size of the heat-absorbing bodies, so that each opening overlaps at least one main part, and preferably covers at least 90% -110%, and most preferably at least 97- 103%, of the area of the opening to the body. Thus, the efficiency of heat exchange increases.
    Furthermore, the device is easy to install in an already existing or a planned ventilation system. This is because the device can be easily adapted and adapted to the dimensions and / or shape of the ventilation system, since the ducts can be provided at any position and can any direction relative to that ventilation system. In particular, there is no need for a separate housing with ventilation ducts extending in all directions, nor for a detector arranged in a complicated green area. oriented in any external Another advantage is that the device according to the invention can be designed to have a large air capacity since both the air ducts leading to the bodies and the air passage between the air ducts can be easily designed with large cross-sections. Thus, the device is very efficient and is also simpler and less expensive to install and manufacture.
    A heat absorbing body is preferably made of a material and having a shape adapted to electrically transfer heat to, and absorb heat from, an air vapor passing through the body. Preferably, the body is designed to have a large surface area to allow rapid transfer of heat energy to and from the air flow.

Similarly, the second air flow channel is assigned to receive and / or discharge the second air flow to or from the ventilation system via a first end of the second channel, while receiving and / or discharging either the first or second air flow having a second end which is adapted to be connected to the other heat-absorbing body. It should be understood that the naming and numbering of the air fl fates, the air ducts, the air passages, the heat-absorbing bodies, etc. are only for the sake of description and that in all other respects they are arbitrary. Similarly, the air flows fl can flow through the air ducts and bodies in both directions, depending on the way the device is set up in the ventilation system. Furthermore, any of the first or second air flows may be incoming or outgoing air.
    According to an embodiment of the invention, the ventilation device comprises at least one air fate control means adapted to control the fate of at least one air fate through the ventilation device, so that the exchange of the air destinies to the heat-absorbing bodies can be controlled. An air fate control means may comprise a throttle cover, a flap, a detector or a throttle valve arranged to control, switch off or change the fate or fate wave of an air flow, depending on its current state.
    Preferably, at least one air flow control means is located within the first or second air flow channel. The internal volume of the air flow duct is large to allow large air flows. By placing the air fate control means inside one of the ducts, the large space in the ducts is utilized so that the device as a whole can be more compactly designed.
    According to an embodiment of the invention, the ventilation device comprises a first air flow control means adapted to allow the first air flow to flow into the second channel through the first air passage in a first, open state and to force the first air flow to continue through the first air flow channel in a second, closed end. state. Preferably, the first air fate control means is also adapted to prevent at least a major portion, preferably at least 90%, and most preferably at least 98% of the second air fate from entering the first air passage and the second air fate channel in its second, closed state.
    Thus, the entry of the first air flow into the second air flow duct can be controlled. Furthermore, it can be ensured that at least a main part of the first air flow continues through the first air flow channel without it leaking into the air passage in the second state of the first air flow control means.
    Thus, the mixing of the two air fl fates is reduced, or it can even be avoided altogether.
    According to another embodiment of the invention, the ventilation device comprises a second air flow control means adapted to allow the first air flow to flow past the air passage and to continue through the first air flow channel in a first, open state, and to force the first air flow into the first air passage in a second, closed state, to prevent at least a major portion of the first air fate from flowing through the first air fate channel in a second, closed state. Thus, it can be ensured that at least a major part of the first air flow passes into the air passage and further into the second duct in the second state of the second air flow control means. Preferably, the second air fate control means is adapted to force at least 90%, preferably at least 98% of the first air fate into the first air passage in its second state.
    According to another embodiment of the invention, the ventilation device comprises a control module adapted to control the first and the second air flow control means to alternate between the first and the second state, respectively, the control module further adapted to control the first and the second air control means to be in different states at the same time. Thus, when the first control means is in the open state and allows the first air flow to enter the lift passage, the control module controls the second control means to be in the closed state to force the first air flow into the first air passage and vice versa. Thus, it is ensured that at least a major portion, preferably at least 90%, preferably at least 98%, of the first air flow is directed into the second air flow channel when the first air flow control means is in the second state. The control module may comprise a mechanical construction, a control circuit and / or a computer with a computer program, or any suitable and most combinations thereof. The control module can also be divided into delar your parts of the equipment or they can be integrated to form only one part.
    According to an embodiment of the invention, the ventilation device comprises a second air passage between the first and the second air d duct arranged to direct at least a part of the second air från from the second air fl duct and into the first air fl duct. Thus, the wave of the second air fate can also be changed to either continue in the second channel and on to the second body, or to be led into the first channel and on to the second body. Preferably, the ventilation device also comprises a third air flow control means adapted to allow the second air flow to flow into the second air passage and on to the first air flow channel in a first, open condition, and to force the second air flow to continue through the second air flow channel in a second airway. , closed state. Thus, the third air flow control means prevents at least preferably at least 90%, and most preferably at least 98% of the second air flow, from flowing into the second air passage and on to the first air flow channel in the second, closed state. According to an embodiment of the invention, the ventilation device comprises a fourth air flow control means adapted to allow the second air flow to pass past the second air passage and to continue through the second air flow channel in a first, open state, and to force the second air flow into the second air passage. in a second, closed condition, to prevent at least a major portion of the second air flow from flowing through the second air flow channel. Thus, at least a major portion of the second air fate is forced to pass into the first air fate channel and on to the first heat absorbing body in a second state by the fourth control means. Preferably, the fourth air control means is adapted to force a major portion, preferably at least 90%, of the second air inlet into the first channel in the closed state, and most preferably at least 98%. Preferably, the device also comprises a control module adapted to control the third and the air flow control means to alternate between being in the first and fourth second states, the control module further being adapted to control the third and the third air fate control means to be in different states at the same time.
    According to an embodiment of the invention, the ventilation device comprises a control means adapted to control the first and the third air flow control means to alternate between being in the first and the second state, respectively, the control module further adapted to control the first and third air flow control means to be in the same state at the same time. Thus, the control module connects the first and third air destiners to each other, so that the first and second air destinies are simultaneously conducted into the first and second air passages, respectively, when the first and third air destroyers are in their first, open state. Preferably, the control module is also adapted to control the second and fourth air flow control means to be in the same state at the same time, and to be in opposite states relative to the first and third air flow control means. Thus, the airflow control module controls the first, second, third and fourth air flow control modules so that the first and second air flows will simultaneously be allowed into the respective air passages and prevented from continuing in the first and second air ducts, or allowed to continue in the first and second air ducts, respectively, while being prevented from entering the air passages.
    According to an embodiment of the invention, at least one of the air fate control means comprises a throttle door mounted on a rotatable shaft, so that the air fate control means is rotatable between its first and its second state. Preferably, all four air fate control means comprise a throttle cover each, mounted on a shaft. Preferably, the shaft is arranged to pass mainly in the middle of the damper door and in the same plane as the damper door, the damper door being balanced on the shaft and the moment of inertia during the rotation being low. In another embodiment, the shaft can be arranged along the only end of the damper cover, whereby the damper cover can be rotated at a smaller angle while its function is maintained.
    According to an embodiment of the invention, the first and the fourth air fate control means are mounted on the same shaft, so that the first and the first air fate control means rotate with each other. Thus, it is possible to rotate the control means mounted on the same shaft between their first and second states by rotating only one shaft and with only one drive unit. Preferably, the second and third air flow control means are also mounted together on a second shaft. However, the damper doors can become heavy for very large ventilation devices, in which case it is preferable to mount each damper door on an individual shaft.
    According to an embodiment of the invention, the ventilation device comprises a first casing comprising an inner cavity which they open the first air duct, and a second casing comprising an inner cavity which they drain the second air duct, the first and second casings being at least one part along at least one part of the length of the first and second air fl fate channels. In one embodiment, the housings are assembled by holding them together. In another embodiment, the housings are assembled by being separated by a common compartment wall. In yet another embodiment, the first and second housings are integrated into a single, common housing, and the air duct ducts are separated by a compartment wall disposed within the common housing. Thus, the distance between is small for these parts, so that the ventilation device is more compact and takes up less space.
    Preferably, the air passages are arranged adjacent to the assembled parts so that the air passages are short. Thus, the air destinies do not have to travel such a long distance through the air passages before they reach the second channel.
    According to an embodiment of the opening, the first and the second air duct are separated by a compartment wall along at least a part of the length of the ducts, the air passages comprising an opening in the compartment wall. Thus, the air passage is very short, and the device can be designed very compact. Preferably, the compartment wall is common to both air ducts, so that the compartment wall forms a wall in both ducts.
    Thus, the distance between the air ducts is mired.
    Preferably, the first air passage includes an opening to the first air flow channel having a width less than or equal to the width of the air flow channel. Preferably, the width of the opening is less than or equal to half the width of the wall surface. Preferably, the opening is further located on one side of the wall surface, seen from a longitudinal direction thereof. Preferably, the other comprises the opening in which the opening is arranged. 11 the air duct also a second opening to the first air fl duct which has a width which is less than or equal to the width of the air d duct.
    Preferably, the second opening is located on the other half of the wall surface, wherein both openings can be placed side by side.
    Preferably, the device further comprises an inner wall arranged to separate the two openings so that different air flows can pass through the two openings without mixing. Preferably, the wall is disposed within either one or both of the first and second air fate channels to prevent mixing of the air fate.
    According to an embodiment of the invention, the ventilation device comprises at least one inner wall arranged to prevent at least a main part of one of the air ducts from entering an air passage. Preferably, the inner wall is arranged to at least partially surround the opening to the air passage inside one of the air ducts. Thus, mixing of the two air vapors is prevented at least in part. According to one embodiment of the invention, it cooperates with at least one of the air fate control means to prevent at least a major part of at least one air fate from entering an air passage. Preferably, an inner wall arranged to define the inner wall is an opening for releasing the air out of or into the air passage, which opening is covered by an air flow control means. Thus, the air fate can be regulated and controlled by changing the state of the air fate organ. Preferably, the inner wall is arranged to surround the opening in cooperation with a wall of the housing and / or an inner fate control means to at least 95%.
    According to an embodiment of the invention, the ventilation device is arranged a first state, in which the ventilation device directs the first and the second air flow to pass right through the first and the second air flow duct, respectively, and a second state, in which the ventilation device directs the first and the second air flow to enter into a first and a second air passage arranged between the first and the second air duct, so that the first air flow fl flows from the first air fl fate channel and into the second air fl fate channel by alternating between the 12 first air passage, and the second air fl fate fl desires from the second the air duct and into the first air duct through the second air passage. Thus, it is guaranteed that the two air flows alternately pass through the first and the second heat absorbing body, respectively, in order to regenerate heat and save costs.
    According to one embodiment of the invention, the device is sized to allow an initial airflow of at least 5,000 m3 / min, preferably at least 7,000 m3 / min and most preferably at least 10,000 m3 / min, based on an air pressure of at most 2 Bar inside the air fl fate channel. Preferably, the device is further sized so as to simultaneously allow a second air flow of at least 5,000 mS / min, preferably at least 7,000 m3 / min and most preferably at least 10,000 m 3 / min, based on an air pressure of at most 2 Bar inside the air flow duct . Thus, the capacity of the device is suitable for very large air flows and large ventilation systems.
    According to another aspect, the invention relates to a ventilation device comprising a first ventilation device as described above, and a heat absorbing module comprising a first and a second to the first and second air ducts in the first ventilation device with a first end, heat absorbing body connected and a second ventilation device correspondingly adapted to control the fl pathways of fate of the first and second air fl destinies to alternately flow to or from the first and second heat absorbing bodies and which are connected to the other ends of the first and second heat absorbing bodies. Thus, an air fate control device is arranged on each side of the heat absorption module. The second ventilation device is preferably also designed as above, but can also be designed in some other way.
    Preferably, both the first and the second ventilation device are adapted to constantly receive or release each air fl destiny via the same opening to a surrounding ventilation system. Thus, the 13 air ducts will be received or discharged to or from the same ventilation duct in the external ventilation system, so that the ventilation ducts connected to the devices always lead the same air duct and always in the same direction.
    Thus, the device can be placed far from either or both of the intake or discharge to the indoor air or to the outdoor air, without Increasing the volume of air that must be vented through the ventilation ducts when changing the air fl fats, before new air reaches the heat-absorbing bodies. Thus, the ventilation device can be placed in a part of a building while the inlet or outlet of the ventilation system is located in another part. In particular, it is an advantage to install the ventilation unit in the basement of a building, while the inlet or outlet is placed on the roof of the building.
    In another embodiment of the present invention, two or three such ventilation devices and / or heat absorbing modules may be provided within the same housing, so that a separate unit is formed. This provides the advantage that the entire unit can be removed or replaced for maintenance or repair.

    DETAILED DESCRIPTION I fi g. 1a-f show an example of a ventilation device 1 according to the invention. The ventilation device 1 year is adapted to control the fate waves for a first 3 and a second 5 air fate to alternate death to a first 6 and a second 8 heat absorbing body for the purpose of providing a heat transfer between the two air destinies. Thus, in a first state of the device 1, the first air 3 fate 3 passes the first body 6 so that the first body assumes the temperature of the first air fl fate, while the second air fl fate 5 passes the second body 8, so that the second body assumes the second air fl fate. temperature. In a subsequent second state of the device 1, the first air flow 3 is directed to pass through the second body 8 while the second air flow 5 is directed to pass through the first body 6. By allowing the device to alternate between being in the first and the second state so that the air fates alternate between passing through the first 6 and the second body 8, a heat transfer is effected between the two air fates.
    The first body 6 is in this example arranged on top of the second body 8, but in another example the bodies can of course be placed on any other suitable way and can also be placed at a distance from each other. The bodies 6, 8 are adapted to be connected with the device 1, which is indicated by the dashed lines in fi g. la and le. In this example, the heat absorbing bodies each comprise a number of metal plates stacked on top of each other and with a number of channels formed between the plates.
    The device 1 further comprises a first air fate channel 7 adapted to guide an air fate through the air fate channel. The first air fate channel 7 comprises a first end 9 adapted to receive or blow out the first air fate 3, and a second end 11 adapted to communicate with the first body. Correspondingly, the device 1 comprises a second air fate channel 13 comprising a first end 15 adapted to receive or blow out the second air fate and a second end 17 adapted to communicate with the second body. In this example, the first air fate channel 7 is placed on top of the second air fate channel 13 to adapt the device to the positions of the two heat absorbing bodies.
    The ventilation device 1 further comprises at least a first air passage 19 which connects the first 7 and the second 13 air ducts to each other and which is arranged to direct at least a part of the first air duct 3 from the first air duct 7 and into the second air duct 13. Thus, the first air flow 3 can be directed directly into the second air flow channel 13 and further to the second body, without having to connect the air flow channels to an intermediate exchange device for switching the air flows.
    The ventilation device 1 further comprises a first air flow control means 21 adapted to allow the first air flow 3 to flow into the second air flow duct 13 through the first air passage 19 in a first, open state, as shown in Figs 1e-f, and to force the first air fl fate 3 to continue in the first air fl fate channel 7 in a second, closed state, as shown in fi gures 1a-d. Thus, the first air fate control means 21 prevents at least a major part of the first air fate 3 from falling into the second air fate channel 13 through the first air passage 19 in the second state. Thus, by changing the state of the first air fate control means 21, the first air fate 3 can be controlled to either pass through the first body by allowing the first air fate to continue through the first air fate channel, or to pass through the second body by allowing it first air flow into the second duct 13.
    The ventilation device further comprises a second air flow control means 23 adapted to allow the first air flow 3 to flow past the first air passage 19 and to continue through the first air flow passage 7 in a first, open state, and to force the first air flow 3 into the air passage 19 in a second , closed state, to prevent the first air 3 fate 3 from da dying through the first air fl fate channel 7. Thus, a larger portion, and preferably the next whole, first air fl fate 3 will be directed into the second air fl fate channel 13 when the second air fl fate control means 23 is in its second condition.
    The device 1 also comprises a second air passage 25 between the first 7 and the second 13 air ducts, which is arranged to direct at least a part of the second air 5 from the second air duct 13 and into the first air duct 7. The ventilation device 1 further comprises a third air fate control means 27 adapted to allow the second air fate to escape into the first air fate channel 7 through the second air passage in a first, open state, and to force the second air fate 5 to continue through the second air fate channel 13 in a second, closed state.
    Thus, the second air flow 5 is prevented from flowing into the first air flow channel 7 through the second air passage 25 in the second, closed state. The device further comprises a fourth air flow control means 29 adapted to allow the second air flow 5 to flow past the second air passage 25 and to continue through the second air flow channel 13 in a first, open state and to force the second air flow 5 into the second air passage in a second , closed state, to prevent the second air fl fate from fl blowing through the second air fl fate channel 13. 17 The ventilation device 1 is arranged to alternate between being in a first or a second state to direct air fl fates 3, 5 between the first and the second body . In the first state of the ventilation device, as shown in Figures 1a-d, the first 21 and the third 27 airway control means are in their second, closed state, while the second 23 and the first 29 airway control means are in their first open state. Thus, the first 3 and the second 5 air destinies are controlled to pass raw through the first 7 and the second 9 air destiny ducts, respectively. In the second state of the ventilation device 1, as shown in Figs. 1, the first 21 and the third 27 airway control means are in their first, open state, and the second 23 and the fourth 29 airway control means are in their second, closed state. Thus, the first 3 and the second 5 air flows to enter the first 19 and the second air passage 25, respectively, so that the first air flow 3 flows from the first air flow channel 7 and into the second air flow channel 13 through the first air passage 19, and the second air 5 fate 5 fl deserts from the second air fl fate channel 13 and into the first air d fate channel 7 through the second air passage 25. By providing air passages 19, 25 between the two air fl fate channels, the air fl destinies can thus be directed and changed separate device for switching the air flows.
    The ventilation device further comprises a control module 31 arranged to control the state of the ventilation device 1. In this example, the control module 31 is adapted to control the states of at least one air fate control module 21, 23, 27, 29. The control module 31 may comprise a microcomputer containing a computer program, or a control program. for processing signals or other data concerning the operation of the device 1.
    The control module 31 may further be connected to a mechanical control system for controlling the movement of the air means or means. In this example, the control module 31 comprises drive units in the form of two electric motors 33 for surfacing the control means, but in another example the control module may comprise drive units in the form of pneumatics. In this example, the control module 31 is further designed to include fl your parts, but in another example, the control module may be integrated into a single unit. The control module 31 is adapted to control the first 21 and the second 23 air fate control means to alternate between being in the first and in the second state, respectively. In order to direct at least a main part, in this example at least 98%, of the first air fate 3 to the respective air fate channels 7, 13, the control module 31 is adapted to control the first 21 and the second 23 air fate means to be in different states at the same time.
    Thus, the first air flow control means 21 will be in its open state, so that it allows the first air flow 3 to enter the first air passage, while the second air flow control means 23 will be in its second state so as to prevent the air flow 3 from continuing. through the first air fate channel 7, and to force the air fate 3 into the air passage 19. The control module 31 is correspondingly adapted to control both the third 27 and the fourth 29 air fate control modules to be in different states at the same time.
    To alternate both air fl fates 3, 5 simultaneously, the control module 31 controls the first 21 and third air styr control modules to be in the same state at the same time, and to control the second 23 and the fourth 29 air styr control means to be in the same state at the same time. Thus, both the first 3 and the second air flow will be controlled to switch between either passing straight through the ducts or switching between the ducts. further adapted that it In this example, the ventilation device comprises a first casing 35 arranged to form a cavity which finions the first air fl duct 7.
    The first casing 35 may, for example, comprise metal plates which are bent and welded to the desired shape of the casing 35. The ventilation device 1 further comprises a similar, second casing 37 adapted to deflect the second air solder ducts 13 from the casing 37. The first ss and the second 37 the casing is in this example connected to each other along at least a part of the length of the first 7 and the second 13 air ducts. In this example, the tails 35, 37 are joined along at least a major portion of the length of the air duct channels. By joining the housings 35, 37 to each other, the distance 19 between the air flow channels becomes short, so that the device 1 will be very compact and so that the device will be provided as a single loop. In this example, the first 35 and second 37 housings also share a common compartment wall 39 separating the first 7 and second 13 air ducts from each other along at least a portion of the length of the ducts, in this example along a major portion of the length of the ducts. Thus, the compartment wall 39 simultaneously forms part of the wall of both the first 7 and the second 13 air ducts.
    The air passages 19, 25 years in this example are arranged adjacent to the joined parts of the housings 35, 37. Thus, the air passages 19, 25 are short because the distance between the two air fl ducts 7, 13 is short. In this example, the first air passage 19 comprises a first opening 41 in the compartment wall 39, whereby the first air flow 3 can easily pass from the first duct 7 and into the second duct 13 through the opening 41.
    The second air passage 25 correspondingly comprises an opening 43 in the compartment wall for allowing the second air flow 5 into the first air flow channel 7.
    In this example, the opening 41 of the first air passage 19 has a width equal to or less than the width of the first air duct 7, in this example less than or equal to half the width of the compartment wall 39, which is the wall of the first air duct 7 in which the opening 41 years arranged. The first opening 41 is furthermore located mainly on one side of the surface of the compartment wall 39, in this example the opening is placed completely on one half of the wall surface seen in the longitudinal direction thereof.
    Correspondingly, the second opening 43 to the second air passage also has a width which is less than or equal to the width of the first air duct 7, in this example less than or equal to half the width of the compartment wall 39. The two openings are further arranged side by side , level with each other and placed on different halves of the compartment wall 39.
    Thus, the first and second air flows can pass between the two ducts, through the openings 41, 43, in level with each other but on different halves of the air fl duct channels.
    The ventilation device also comprises a first inner wall 45 arranged to prevent the second air flow 5 from entering the first air passage 19.
    The inner wall 45 is also arranged to separate the openings 41, 43 of the air passages 19, 25 from each other. In this example, the first inner wall is arranged to at least partially surround the opening 41 in order to prevent the second air flow 5 from entering the opening 41 and the first air passage 19. Thus mixing of the two air sections is avoided.
    The first inner wall 45 is further arranged to cooperate with the first air flow control means 21 to prevent the second air flow from entering the first air passage 19. In this example, the first inner wall 45 is arranged to form an opening to the second channel for letting the first air flow out of the air passage 19, which opening is covered by the first air flow control means 21. Thus, the air flow can be regulated and controlled by changing the state of the first air flow control means.
    In this example, both the first air fate controller 21 and the inner wall 45 are disposed within the space formed by the second air fate channel 13. Since the air fate channels are large to allow a large air fate, there is sufficient space to accommodate the inner wall and the control means. In this example, the first wall 45 comprises a portion arranged perpendicular to the direction of fate of the air passages through the device, and which is arranged on the opposite side of the opening 41 in the compartment wall 39 relative to the air fate control means 21. The perpendicular part of the wall section is further connected to the side wall 35.
    The inner wall 45 further comprises a part arranged longitudinally with the direction of fate through the device and parallel to the side wall of the housing 35.
    The longitudinal part is located on the opposite side of the opening 41 in the compartment wall 39 relative to the side wall of the housing 35. Thus, the inner wall section 45 surrounds the opening on all sides in cooperation with the side wall of the housing and with the first air flow control means. The inner wall 45 further defines a part of the air passage 19 in cooperation with the side wall of the housing 35. The device 1 further comprises a corresponding second inner wall 47 arranged inside the space in the first duct 7, and arranged to at least partially surround the opening 43 in the compartment wall 39 in order to prevent the first air flow from entering the second air passage 25 in cooperation with the third air destiny control device 27.
    In this example, each of the air fate control means 21, 23, 27, 29 comprises a throttle cover 49 mounted on a rotatable shaft 51. Thus, the air fate control means are rotatable between their respective first and second states. In this example, the shutter doors are mounted on a rotatable shaft which passes through the center of the shutter door and are arranged in the same plane as the spread of the shutter door. Thus, the moment of inertia during rotation of the damper doors is reduced, so that the energy consumption to drive the rotation is reduced.
    The use of shutter doors arranged on such rotatable shafts provides highly efficient and durable control means for controlling the air flow to the device 1.
    In this example, the first 21 and the fourth 29 are the air fate control means mounted on the first one and the air fate control means rotating with each other. Correspondingly, also the same shaft, so that the fourth second 23 and the third 27 control means mounted on the same shaft.
    Thus, it is possible to control all four control means with only two drive units 33.
    I fi g. 2 shows a second example of a construction of an air fate control means 55 air fate channel 56.
    The air flow control means 55 comprises a throttle cover 57 mounted on a arranged in a rotatable shaft 59 arranged along one edge of the throttle cover 57.
    The air fate control means 55 is further located in connection with an opening 61 to an air passage, so that the rotatable shaft is arranged along one edge of the opening. The shutter hatch 57 is further arranged with a length that is as long or longer than the height of the air duct 56. In a first state, the throttle cover 57 is rotated to cover the opening 61, the air flow being prevented from entering the opening and continuing inside the air flow channel 56. In a second state, as shown in fi g. 2, the damper door is rotated so that the opening 61 is left open and so that the damper door makes contact with the inner roof of the air fate channel 56, the air fate being prevented from continuing inside the air fate channel and being forced into the opening 61 to the air passage. Thus, only a throttle cover 57 is needed to control the air flow.
    I fi g. 3 shows an example of a ventilation device 63 according to the invention.
    The ventilation device 63 comprises a first ventilation device 65 designed in the same way as the ventilation device 1 described in fi gures 1a-f. The device 63 further comprises a heat absorbing module 67 comprising two heat absorbing bodies, the heat absorbing module 67 being arranged in communication with the ventilation device 65 with a first end of the module 67. The ventilation device 63 further comprises a second ventilation device 69 arranged in a fluid communication device heat absorbing module 67. Thus, each of the two air outlets passes through the heat absorbing module 67 and both ventilation devices 65, 69. In this example, the first ventilation device 65 is directly connected to the heat absorbing module 67. Correspondingly, the second ventilation device is directly connected to the other end of the heat absorbing module 67, for controlling the air flows.
    The ventilation devices 65, 59 years are both adapted to control the fl pathways of fate of the first and the second air fl fate to pass alternately between the two heat-absorbing bodies. Thus, the paths taken by the air fates on both sides of the heat absorbing module 67 are alternated, the distance between the position of the shift and the heat absorbing bodies being short. This means that the volume of air that must be flushed at each change of air before the new air reaches the heat-absorbing bodies is small.
    Thus efficiency.
    The ventilation device 63 is located far from both the intake and the exhaust for both the indoor air and the outdoor air. The ventilation devices 65, 69 and the heat-absorbing module 67 can in this example be arranged to be modular and mainly box-like with a rectangular shape, with which the devices and the module can be installed more easily. Due to the modular design of the ventilation device 63, it is very easy to replace any or all of the devices 65, 69 or module 67 by simply disconnecting and removing the desired device or module and replacing it with a new device or module in case of accident. of error.
    I fi g. 3 also shows external ventilation ducts 71, 73, 75, 77 connected to the airflow 63 to direct an incoming and an outgoing air leak to the device. In this example, the first ventilation duct 71 is adapted to direct the incoming air flow into the device 65 from the outdoor air, the second ventilation duct 73 is adapted to direct the outgoing air flow outdoors, the third ventilation duct 75 is adapted to direct the incoming air flow indoors and the fourth ventilation duct 77 is adapted to direct the outgoing air flow from the indoor air into the device. The ventilation devices 65, 69 are in this example thus arranged to receive or blow out the same air flow through the same opening in the ventilation device, the openings of the ventilation devices 65, 69 always being connected to the same external ventilation duct leading to an intake or an outlet.
    The invention is not limited to the examples shown, but can be varied freely within the scope of the following claims. In particular, the various examples described may be combined or substituted with each other, and functional parts may be exchanged for other parts having a corresponding function.
    Furthermore, the functions of the two different air fate control modules can be combined into a single control module, as described with reference to fi g. A ventilation device, or device, may comprise three or fl your air fl ducts and heat absorbing bodies for guiding three or separ your separate air den fates. The air duct ducts do not have to be connected but can be arranged separately and connected with an air passage in the form of a ventilation duct or the like.
