专利说明:

[0001] The present invention relates to equipment for mechanical ventilation devices, including dual flow ventilation devices. With the increasing tightness of the housings, mechanical ventilation is increasingly needed to ensure sufficient hygienic air exchange rates. In the context of energy efficiency at the beginning of the 21st century, dual-flow ventilation with heat exchanger is an increasingly popular technology. 10 Double-flow ventilation with heat exchanger is known for individual dwellings since the 1970s: one fan extracts air in the service rooms (kitchen, bathroom and toilet), another blows fresh air into the rooms main (living room, dining room, bedrooms). The two streams intersect in a particular element named heat exchanger, in which the extracted air (warmer) exchanges its calories with the fresh air (colder). This arrangement makes it possible to recover a large part of the energy necessary for heating the air and thus to considerably reduce the energy requirement of the dwelling. In recent years, dual flow ventilation has also been associated with certain forms of air modulation, sensors placed in different rooms measure the need for ventilation and special devices make it possible to adapt the quantity of ventilated air to the real needs of the room. housing. These technologies can reduce the power consumption of the 25 fans and extend the life of the filters. There are currently dual flow ventilation systems whose extraction flow is modulated by sensors in the service rooms. The insufflation rate is then calibrated to that of extraction to maintain an equilibrium of the two flows, this characteristic is important for the efficiency of the heat exchanger. The disadvantage of this type of modulation is that the need for insufflation may not be satisfied by the flow required for extraction, and the fixed distribution of flow rates does not favor the parts with higher need for insufflation. Also less common are dual flow ventilations, the insufflation rate of which is modulated by sensors in the main rooms. It is then the rate of extraction which is wedged on that of insufflation.
[0002] Here again we find the previous, inverted defect, namely that extraction requirements may not be satisfied by the insufflation rates, and that the fixed distribution of flow rates does not favor the parts with the greatest need for extraction.
[0003] Other dual flow ventilation devices also exist, which are more complex, and which modulate both extraction and insufflation flow rates from sensors placed in all rooms and connected to a centralized control. Different balancing strategies are then used according to methods specific to each manufacturer of dual flow ventilation.
[0004] The object of the present invention is to remedy, in particular, the aforementioned drawbacks. Thus, the present invention relates to equipment for a dual-flow ventilation device, the ventilation device being modulated on the extraction, respectively the blowing, of air, of an enclosure comprising two groups of at least one piece of equipment. the first and the second second, the equipment being remarkable in that it comprises at least one sensor for determining the insufflation needs of the first group, and a hub for managing a flow of insufflation, respectively d extraction from the second group, comprising at least one means for managing the insufflation flow, respectively extractable, controllable slaved to the insufflation needs of the first group and at least one pressure sensor in the hub, the hub being integrated in the double-flow ventilation device so as to receive the insufflation or extraction flow respectively.
[0005] Throughout the application, the expression "upstream" is defined as meaning any point that comes before the point considered in the direction of flow of any air flow and the expression "downstream" as meaning any point coming after the point considered in the flow direction of the airflow.
[0006] Throughout the application, the term extraction flow must be understood as any airflow upstream of the heat exchanger and the expression flow of insufflation must be understood as any flow of air downstream of the heat exchanger. This type of equipment makes it possible to complete the dual flow ventilation device so as to totally enslave it, both for managing extraction flows and for managing insufflation flows, in a simple manner. reliable, inexpensive, and practical in that it can be installed on any dual flow ventilation device, even if such a dual flow ventilation device is already installed. According to other optional technical features of the invention, considered alone or in all possible combinations: the first group has several parts, the equipment comprises a plurality of insufflation need determination sensors each installed in a part of the first group; when it is integrated downstream of the heat exchanger, the hub comprises several management valves each managing the insufflation flow for each part of the first group; - the second group presents several pieces; when it is integrated upstream of the heat exchanger, the hub comprises several management valves each managing the extraction flow for each piece of the second group; - The equipment comprises at least one inflation compensation valve that can be integrated in the dual flow ventilation device; - The equipment comprises at least one extraction compensation valve that can be integrated in the dual flow ventilation device. The present invention also relates to a method of implementing an equipment according to the invention.
[0007] According to other optional technical features of the invention, considered alone or in all possible combinations, the method may have the following steps: - control by the hub of the opening of each insufflation flow management valve in function information collected by the sensors for determining insufflation needs to best adapt the flow of insufflation to the needs of insufflation; control by the hub of the opening of each insufflation flow management valve as a function of the pressure measured in the hub or in insufflation nozzles in order to best adapt the insufflation flow to the insufflation needs; control by the hub of the extraction compensation valve to modify the extraction flow and adapt it to the insufflation flow, for example if the insufflation needs are greater than the extraction requirements; - control by the hub of the compensation valve to the insufflation to maintain a target pressure in the hub or in insufflation nozzles, for example if the extraction needs are greater than the need for insufflation; the target pressure in the hub or in the insufflation nozzles can be kept constant as a function of the insufflation rate; the target pressure in the hub or in the insufflation nozzles may gradually vary as a function of the insufflation rate; - the hub receives and processes additional information from the dual flow ventilation device; - The hub processes and transmits additional information to the dual flow ventilation device. Other features and advantages of the present invention will appear on reading the detailed description which follows, according to the embodiments given by way of non-limiting examples and with reference to the single appended drawing in which: Figure 1 shows a diagram of a dual flow ventilation device equipped with equipment according to an embodiment of the present invention. Referring to Figure 1 there is described an equipment 1 for a ventilation device 2 double flow. The ventilation device 2 is modulated on the extraction of air, that is to say it comprises extraction mouths, for example the diameter is variable depending on the extraction requirements defined by the needs of insufflation. The modulation of the air extraction is effected by means of extraction valves of the ventilation device 2, or valves or valves.
[0008] The ventilation device 2 is a dual flow ventilation device 2 of an enclosure comprising two groups of four parts each, the first and the second second. The enclosure may include other rooms not belonging to these two groups that would not be affected by the dual flow ventilation.
[0009] Each of the parts of the second group receives an extraction mouth El, E2, E3, E4 of the ventilation device 2 to form an extraction flow, whose section is variable depending on the extraction requirements. Each of the parts of the first group receives an insufflation mouth S1, S2, S3, S4 of the ventilation device 2 through which an insufflation fan of the ventilation device 2 can discharge at least a portion of the ventilation device 2. insufflation flow. The equipment 1 comprises four sensors for determining the need for insufflation of the first group. A sensor being disposed in each part of the first group. These sensors may especially be presence sensors, carbon dioxide, humidity. It is understood that each piece may include several sensors for a more precise determination of insufflation needs. The type of sensor is chosen according to the desired effect, for example, when it is desired to control a flow of insufflation as a function of humidity, a humidity sensor will be chosen.
[0010] The equipment 1 also comprises a hub 3 for managing an insufflation flow integrated in the dual flow ventilation device 2 so as to receive the insufflation flow. More specifically, the hub 3 is integrated in the ventilation device 2 so as to manage the distribution of the blowing flow from a heat exchanger 4 of the ventilation device 2 for each of the parts of the first group. The hub 3 comprises four controllable insufflation flow management valves controlled by the insufflation needs of the first group determined by the insufflation need determination sensors. The four valves make it possible to open or close, totally or partially, in a discrete or continuous manner, the access of the insufflation flow to each of the parts of the first group. The hub 3 also comprises a pressure sensor in the hub 3. The extraction flow is led by a fan of the ventilation device 2 to the exchanger 4.
[0011] In general operation of the equipment 1 and the ventilation device 2, the hot air of the parts of the second group enters through the extraction mouths with variable diameter thanks to the fan in an extraction nozzle 5 giving onto the exchanger of heat 4, thus forming the hot extraction stream. The hot extraction stream flows to the heat exchanger 4. In parallel, fresh cold air from the outside of the chamber is withdrawn to be supplied by an insufflation nozzle 6 until to the heat exchanger 4, thus forming a cold inflation flow. Then a heat transfer takes place between the hot extraction stream and the cold insufflation flow within the heat exchanger 4, the insufflation flow then comes out of the heated heat exchanger 4, thus forming a hot insufflation flow. The hot insufflation flow then flows in the blowing nozzle 6 to a distribution node 7 from which a plurality of insufflation nozzles (6a, 6b, 6c, 6d) emanate downstream. Upstream of each of the insufflation nozzles (6a, 6b, 6c, 6d) are installed the insufflation flow management valves of the hub 3. When they are opened, these valves allow to pass the insufflation flow which then engulfs in the nozzles (6a, 6b, 6c, 6d) overlooking the parts of the first group. The insufflation flow then flows into the rooms of the first group. In one mode of operation of the ventilation device 2, the pressure at the inlet of the ventilation device 2, that is to say at the level of the extraction nozzle 5, is kept constant while valves, or any other device, for example valves or extraction valves, makes it possible to modulate the extraction flow. When an extraction valve opens to adapt to the need of a part of the first group, the pressure in the extraction nozzle 5 drops and the ventilation device 2 then accelerates the extraction fan to adjust the pressure of the extraction nozzle 5 on the desired target pressure. In parallel with this adjustment, the ventilation device 2 also accelerates the insufflation ventilator to restore the balance between the extraction flow and the insufflation flow. The thus increased flow rate is distributed proportionally to the non-variable opening of the insufflation valves of the ventilation device 2. The hub 3 then makes it possible to control, by adjusting the valves for managing the insufflation flow of the hub 3 as a function of the insufflation requirements of the first group, the pressure at insufflation, that is to say the pressure in the various blowing nozzles 6, 6a, 6b, 6c and 6d. In the example shown in FIG. 1, the hub 3 comprises an inflation compensation valve 8 integrated in the dual flow ventilation device 2, as well as an extraction compensation valve 9, itself also integrated in the ventilation device 2 double flow. The extraction compensation valve 9 makes it possible, if necessary, to restore the equilibrium between the extraction flow and the insufflation flow from the insufflation requirements. In the absence of a compensation valve at the extraction 9, the section of the extraction mouths El, E2, E3, E4 can be modulated to restore this balance. The inflation-compensating valve 8 makes it possible, if necessary, to maintain a target pressure in the insufflation nozzles 6, 6a, 6b, 6c and 6d, whatever the extraction flow generated in the extraction nozzle 5 Generally only one compensation valve 8 or 9 at a time is active. It is possible, however, that the two compensation valves 8 and 9 are simultaneously active in exceptional cases, for example in case of over-ventilation, that is to say when the intensity of the insufflation flow is very important. The insufflation requirements in the first group pieces are read by the insufflation demand determination sensors installed in the first group pieces. The extraction requirements are slaved to the pressures in the nozzles 5, 6, 6a, 6b, 6c and 6d. A particular mode of operation of the equipment 1 in conjunction with the ventilation device 2 would be that the equipment 1 does not intervene in the modulation of the extraction flow but only to dimension the extraction flow in function insufflation requirements, the compensation valve extraction 9 would then no longer be necessary for the operation of the assembly formed by the equipment 1 and the ventilation device 2. It is the extraction needs that drive the ventilation device 2 on which the equipment is grafted 1. The insufflation flow, identical to the extraction flow, is distributed in each room according to the need, the possible supplement passes through the insufflation compensation valve 8 which can be placed anywhere. Another particular mode of operation of the equipment 1 in conjunction with the ventilation device 2 would be that the equipment 1 does not include a compensation valve to the insufflation 8. In this case, the hub 3 would then only function to better distribute the flow of insufflation by adjusting the settings of the management valves of the insufflation flow of the hub 3, the flow of insufflation is sufficient or not to meet the needs of 'insufflation. This is the greatest need, extraction or insufflation, which drive the ventilation device 2 on which is grafted equipment 1. The insufflation flow is distributed in each room of the first group according to the needs of In actual insufflation, they may be greater than actual insufflation needs since insufflation pressure is not limited. On the other hand, the inflation compensation valve 8 may possibly be replaced, at least in part, by a particular management of the insufflation flow management valves of the hub 3. In this case, the adjustment of Hub 3 insufflation flow management valves depend not only on the need for insufflation in the first group of rooms, but also on the need for extraction if they exceed the need for insufflation. The valves for managing the insufflation flow of the hub 3 are then more open than if their adjustment depended only on the insufflation needs. Another particular mode of operation of the equipment 1 in conjunction with the ventilation device 2 would be that the equipment 1 does not include compensation valves to the insufflation 8 and extraction 9. In this case of figure, it is the extraction requirements that drive the ventilation device 2 on which is grafted the equipment 1. The insufflation flow, identical to the extraction flow, is distributed in each room according to the need, the pressure in insufflation is neither guaranteed nor limited. Management of the insufflation flow management valves of the hub 3 with the pressure taken into account could partially act as a compensation valve at the insufflation 8 and limit the pressure.
[0012] When there is a complete control of the ventilation device 2 on which the equipment 1 is grafted, that is to say when the compensation valves have been activated at the extraction 9 and at the insufflation 8 , it is the needs, extraction or insufflation, the largest that drive the ventilation device 2 which is grafted equipment 1. The insufflation flow is distributed in each room of the first group as needed actual insufflation, the possible supplement passes through the compensation valve blowing 8 or extraction 9 depending on the case; these compensation valves can be placed anywhere. The pressure to insufflation is controlled.
[0013] In the following, are described in more detail modes of operation of the equipment 1 in conjunction with the ventilation device 2. In each of the operating modes that will be described, we choose to start from a situation in which the flows QE extraction and Os insufflation are balanced and the target pressure in the extraction nozzle 5 is PE and the target pressure in the blowing nozzle 6 is P.
[0014] In the first detailed operating mode, the extraction compensation valves 9 and the insufflation valves 8 are closed, or do not exist, that is to say that their respective openings VdCe and VdC are zero. When the extraction needs increase, then the extraction valves of the ventilation device 2 increase their opening, which induces a decrease in the pressure PE. The exhaust fan then reacts to restore the target pressure PE, resulting in an intensification of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the insufflation flow Os. This results in an increase in the pressure Ps. The pressure sensor in the hub 3 will detect this pressure increase Ps and act on the inflation compensation valve 8 to open it, that is to say that VdCs increases. This results in a lowering of the pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act if necessary on the compensation valve blowing 8 to reach the target pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used, in particular for controlling the more or less sophisticated insufflation compensation valve 8, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. Finally, the two extraction and insufflation flows are again balanced with new values corresponding to the new requirements, PE and Ps are at the nominal values. When the extraction needs decrease, then the extraction valves of the ventilation device 2 reduce their opening, which induces a rise in the pressure PE. The exhaust fan then reacts to restore the target pressure PE, resulting in a reduction of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the flow of insufflation Q. This results in a drop in pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the extraction compensation valve 9 to open it, that is to say that VdCE increases. This results in a decrease of the PE pressure. The exhaust fan of the ventilation device 2 then reacts to restore the pressure PE. This results in an increase of the extraction flow QE. The insufflation blower then reacts to balance the Q insufflation flow. This results in a rise in the PE pressure. The pressure sensor in the hub 3 will detect this increase in pressure PE and act if necessary on the compensation valve at the extraction 9 until reaching the target pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used, in particular for controlling the more or less sophisticated extraction compensation valve 9, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. Finally, the two flows of extraction and insufflation are again balanced with values corresponding to the old needs, since the need for insufflation has not changed while those of extraction have decreased and considering that insufflation commands . PE and Ps are at nominal values. When the demand for insufflation increases, then the insufflation valves of the equipment 1 increase their opening, which induces a decrease in pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the extraction compensation valve 9 to open it, that is to say that VdCE increases. This results in a decrease of the PE pressure. The exhaust fan then reacts to restore the PE pressure. This results in an increase of the extraction flow QE. The insufflation ventilator then reacts to balance the Os insufflation flow. This results in an increase of Ps. Again there may be a few rounds before a new equilibrium. Finally, the two flows are again balanced with new values corresponding to the new needs, PE and Ps are at the target values. When the insufflation demand decreases, this induces an increase in pressure P. The pressure sensor in the hub 3 will detect this pressure increase Ps and act on the inflation compensation valve 8 to open it, it is that is, VdCs increases. This results in a lowering of the pressure P. Finally, the two flows are again balanced with the same initial values corresponding to the old requirements, PE and Ps are at the target values.
[0015] In the second detailed operating mode, the inflation compensation valve 8 is closed, or does not exist, that is to say that its opening VdCs is zero, and the extraction compensation valve 9 is open, that is to say that its opening VdCE is not zero. When the extraction needs increase, then the extraction valves of the ventilation device 2 increase their opening, which induces a decrease in the pressure PE. The exhaust fan then reacts to restore the target pressure PE, resulting in an intensification of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the insufflation flow Cls. This results in an increase in pressure P. The pressure sensor in the hub 3 will detect this pressure increase Ps and act on the extraction compensation valve 9 to close it. This results in an increase in PE. The exhaust fan then reacts to restore the PE pressure. This results in a decrease in the extraction flow QE. The insufflation ventilator then reacts to balance the Os insufflation flow. This results in a decrease in the pressure Ps. Depending on the result and the reaction algorithms used, in particular for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, it can there are a few round trips of this type before the system equilibrates. It is also possible that the closure of the compensation valve extraction 9 is not sufficient to balance the pressures, the hub 3 will then act on the inflation compensation valve to open it, It results in a decrease of the pressure P. The pressure sensor in the hub 3 will detect this pressure drop and act or not on the compensation valve on blowing until the nominal pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used (control of the compensation valve more or less sophisticated, with or without pre-calculation of the result, hysteresis on the pressure, ...) there may be some return of this type before the system equilibrates. Finally the two flows are again balanced with new values corresponding to the new higher need, if the extraction compensation valve 9 has opened, or equal to their original value if the extraction compensation valve 9 is remained closed, according to the initial imbalance and the amplitude of the variation. PE and Ps are at the target values.
[0016] When the extraction needs decrease, then the extraction valves of the ventilation device 2 reduce their opening, which induces a rise in the pressure PE. The exhaust fan then reacts to restore the target pressure PE, resulting in a reduction of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the insufflation flow Os. This results in a drop in pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the extraction compensation valve 9 which is open, to open even more. This results in an increase in QE. The blower fan of the ventilation device 2 then reacts to balance QE and Os. This results in a decrease in the pressure P. Depending on the result and the reaction algorithms used, especially for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, it can there are a few round trips of this type before the system equilibrates. Finally, the two flows of extraction and insufflation are again balanced with values corresponding to the old needs, since the need for insufflation has not changed while those of extraction have decreased and considering that insufflation commands . PE and Ps are at nominal values.
[0017] When the insufflation demand increases, this induces a decrease in the pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the extraction compensation valve 9 to open it larger, c that is, VdCE increases. This results in a decrease of the PE pressure. The exhaust fan then reacts to restore the pressure Pe. This results in an increase of the extraction flow QE. The insufflation ventilator then reacts to balance the QE insufflation flow. This results in a rise in P. Again, there may be a few rounds before a new balance. Finally, the two flows are again balanced with new values corresponding to the new needs, PE and Ps are at the target values. When the insufflation demand decreases, this induces an increase in the pressure P. The pressure sensor in the hub 3 will detect this pressure increase Ps and act on the extraction compensation valve 9 to close it. The exhaust fan then reacts to restore the PE pressure. This results in a decrease in the extraction flow QE. The insufflation ventilator then reacts to balance the Os insufflation flow. This results in a decrease of the pressure Ps. Depending on the result and according to the reaction algorithms selected (control of the compensation valve more or less sophisticated, with or without pre-calculation of the result, ...) there may be some round-trip of this type before the system equilibrates. It is also possible that the closing of the compensation valve at the extraction 9 is not sufficient to balance the pressures, the hub 3 will then act on the inflation compensation valve to open it, it results in a decrease of the pressure P. The pressure sensor in the hub 3 will detect this drop in pressure and act or not on the compensation valve on blowing until reaching the target pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used (control of the compensation valve more or less sophisticated, with or without pre-calculation of the result, hysteresis on the pressure, ...) there may be some return of this type before the system equilibrates. Finally the two flows are again balanced with new values corresponding to the new need. PE and Ps are at the target values.
[0018] In the third detailed mode of operation, the inflation compensation valve 8 is open, that is to say that its opening VdCs is not zero, and the compensation compensation valve 9 is closed, or does not exist, that is to say that its opening VdCE is zero.
[0019] When the extraction needs increase, then the extraction valves of the ventilation device 2 increase their opening, which induces a decrease in the pressure PE. The exhaust fan then reacts to restore the target pressure PE, resulting in an intensification of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the insufflation flow Os. This results in an increase in the pressure Ps. The pressure sensor in the hub 3 will detect this increase in pressure Ps and act on the inflation compensation valve to open it larger. This results in a decrease in P. Depending on the result and the reaction algorithms used, especially for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. Finally the two flows are again balanced with new values corresponding to the new need. PE and Ps are at the target values. When the extraction needs decrease, this leads to an increase in the PE pressure. The exhaust fan then reacts to restore the target pressure PE, resulting in a reduction of the extraction flow QE. The blower fan of the ventilation device 2 then reacts to balance the insufflation flow Os. This results in a lowering of the pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the inflation compensation valve 9 which is open, to close it. This results in a rise in P. Depending on the result and the reaction algorithms used, particularly for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. It is also possible that the closing of the compensation valve at the insufflation 8 is not sufficient to balance the pressures, the hub 3 will then act on the extraction compensation valve 9 to open it. This results in a decrease of the PE pressure. The exhaust fan then reacts to restore the PE pressure. This results in an increase in the QE extraction flow. The insufflation ventilator then reacts to balance the Os insufflation flow. This results in an increase in pressure P. The pressure sensor in the hub 3 will detect this increase in pressure and act or not on the compensation valve extraction until reaching the target pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used (control of the compensation valve more or less sophisticated, with or without pre-calculation of the result, hysteresis on the pressure, ...) there may be some return of this type before the system equilibrates. Finally the two flows are again balanced with new values corresponding to the new need. PE and Ps are at the target values.
[0020] When the insufflation needs increase, this results in a fall in the pressure P. The pressure sensor in the hub 3 will detect this pressure drop Ps and act on the inflation compensation valve 9 which is open, for the close it. This results in a rise in P. Depending on the result and the reaction algorithms used, particularly for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. It is also possible that the closing of the compensation valve at the insufflation 8 is not sufficient to balance the pressures, the hub 3 will then act on the extraction compensation valve 9 to open it. This results in a decrease of the PE pressure. The exhaust fan then reacts to restore the PE pressure. This results in an increase in the QE extraction flow. The insufflation ventilator then reacts to balance the Os insufflation flow. This results in an increase in the pressure Ps. The pressure sensor in the hub 3 will detect this increase in pressure and act or not on the compensation valve on extraction until reaching the target pressure Ps. Depending on the amplitude of the variation and the reaction algorithms used (control of the compensation valve more or less sophisticated, with or without pre-calculation of the result, hysteresis on the pressure, ...) there may be some return of this type before the system equilibrates. Finally the two flows are again balanced with new values corresponding to the new higher need, if the extraction compensation valve 9 has opened, or equal to their original value if the extraction compensation valve 9 is remained closed, according to the initial imbalance and the amplitude of the variation. PE and Ps are at the target values. When the insufflation demand decreases, this induces an increase in the pressure P. The pressure sensor in the hub 3 will detect this increase in pressure Ps and act on the insufflation compensation valve 8 to open it larger. This results in a decrease in P. Depending on the result and the reaction algorithms used, especially for controlling the more or less sophisticated compensation valve, with or without pre-calculation of the result, hysteresis on the pressure, there may be a few round trips of this type before the system is balanced. Finally, the two extraction and insufflation flows are again balanced with values corresponding to the old needs, the extraction needs have not changed. PE and Ps are at nominal values.
[0021] Over-ventilation passages are still possible, increasing the extraction flow by increasing the PE pressure will result in an increase in Ps and a reaction of the system to reduce the openings but the fan compensation will go beyond the reaction possibilities of the hub. 3; a direct connection (wired or otherwise) can also simplify this mode of operation by avoiding acoustic disadvantages (too high rise of Ps).
[0022] Information can also be retrieved from the equipment 1 to the control device of the initial dual flow ventilation device 2 for example on the operation of the valves for managing the insufflation flow of the equipment 1, the insufflation flows per piece or the air quality levels per room but these links (in one direction or the other) are not necessary for the operation of the invention. In the same way information can also be reassembled from the ventilation device 2 to the equipment 1.
[0023] It goes without saying that the invention is not limited to the embodiments described above as examples but that it includes all technical equivalents and variants of the means and steps described and their possible combinations.
