BUILDING EXHAUST FAN INSTALLATION FRAME AND
EXHAUST AIR CONTROL SYSTEM Field of application The application relates generally to the installation frame of exhaust exhaust fans in a building and to the exhaust air control system. Background The most popular method of ventilation in buildings, such as apartment buildings, has been mechanical exhaust ventilation in the 1960s and 2000s. In the mechanical exhaust ventilation system of apartment buildings, an exhaust air fan installed in connection with the exhaust air duct removes room air through the exhaust air valves in the apartments to the exhaust air duct, along which the exhaust air is directed to the roof of the apartment building and out of the apartment building. The exhaust fans are installed either directly on the exhaust air duct - on the roof, or using an installation frame that is easy to install between the bushing and the exhaust fan. When the exhaust air fan removes air from the apartments, a vacuum is created in them, whereby due to the vacuum, fresh air replacing the air to be removed enters the apartments either in a controlled manner through fresh air valves or uncontrollably through the apartment building structures. N Exhaust fans usually operate at two speeds and clock N control. In this case, the timer-controlled exhaust air fan operates at either half or S full power, depending on the estimated occupancy rate of the block of flats. Nn> Summary = S 25 —One object of the invention is to solve the problems of the prior art and to provide both a safe exhaust fan mounting frame and an easy-to-maintain controller connected to an exhaust fan, which makes it possible to convert “non-intelligent” exhaust fans to intelligent. Thanks to the intelligence added to the extract air fan, it is possible to implement the necessary ventilation based on the measurement data, for example by preventing the loss of thermal energy through ventilation, increasing living comfort, increasing safety in apartments, removing drafts from apartments, enabling nighttime ventilation in apartments, fire safety and the removal of mechanical noise from exhaust fans. —One object of the invention is achieved by an installation framework and control system which meet the requirements of independent protection. Some embodiments of the invention are an installation frame and a control system according to independent protection requirements. According to an embodiment of the invention, the installation frame of the building exhaust fan has a frame structure and an inner surface structure. The lower part of the frame structure is intended to be installed towards the bushing of the building and the upper part towards the exhaust air fan to be installed on it. The frame structure surrounds the inner surface structure so that it does not cover the lower and upper parts of the inner surface structure. The inner surface structure forms a suction channel that allows the exhaust air to flow through the frame. A controller is installed inside the mounting frame, which is adapted to measure the exhaust air flowing in the suction duct and, on the basis of the measurement, to form a control command for the exhaust air fan for controlling the operation of the exhaust air fan. According to an embodiment of the invention, the building exhaust air control system has at least one exhaust air fan, an installation frame according to the above embodiment connected to each exhaust air fan and a control server connected to each frame via a telecommunication network.
Other embodiments of the invention are set out in the dependent claims N to O 25. <Q = Short explanation of the pictures

Fig. 1b - shows a cross-section of a two-part frame from above and parts of the guide with the side surface structure of the inner frame structure removed, from the side Fig. 1c = shows the inner frame structure of a two-part frame pulled out of the outer frame structure Fig.1d = shows a 2 Functional parts of the frame connected to the exhaust air fan Detailed description of the figures Fig. 1a-1d show an exhaust air fan (top extractor) 108 to be installed in the outlet (duct, chimney) 106 of the building 100, e.g. a block or terraced house, on the roof 102 110, by means of which the controller (control unit) 112 is included, the fan 108 has been updated to be intelligent.
The fan 108 is mounted by a frame 110 from the interior of the building 100 to its roof 102, at the end of the exhaust air duct 104 through its roof structures, whereby the exhaust air 114 exits the building 100 through the frame 110 and the fan 108.
In the fan 108 shown, the exhaust air 114 exits the protective frame - (diffuser) 116 from the air vents 118 at its top, but there are other options for directing the exhaust air 114 out of the fan 108 according to the type of fan.
o The purpose of the frame 110 is to facilitate the installation of the fan 108 and to modernize it by means of the controller 112 so that the controller 112 makes O 25 decisions as to how the fan motor 120 of the fan 108 should operate on the basis of the measurement data it has received. TY inputs (control) CO.
Ia “The frame 110 includes a frame structure 122 and an inner surface structure 124, the frame structure 122 of which 2 surrounds, as shown, so as not to cover the lower and upper portions 126, 128 of the inner surface structure S30.
O 5 The profile of the frame structure 122 is square as shown, but may alternatively be rectangular, cylindrical or otherwise. Profile format
The lower part 130 of the frame structure 122 is intended to be mounted towards the lead-through 106 and the upper part 132 in turn towards the fan 108 to be mounted on it. The inner surface structure 124 forms a suction duct 134 in the frame 110 starting from the lower part 126 of the inner surface structure 124 the flow of incoming exhaust air 114 through the frame 110 to the fan 108. The cross-sectional profile of the side surface structure 124 is circular (circular) as shown, but may alternatively be oval (elliptical), square, rectangular, polygonal, or the like. The frame structure 122 further includes a side portion 133 which, together with the lower surface 130, the upper portion 132 and the outer surface of the inner surface structure 124 facing the side portion 133, defines a protected space in which the guide 112 is mounted. The mounting of the frame 110 and the fan 108 on the bushing 106 is accomplished by first installing the seal (s) 136 on the top of the bushing 106 as shown and then fitting the frame 110 on the seal 136 so that the interface between the top of the bushing 106 and the bottom 130 of the frame 110 becomes tight, and the exhaust air 114 is able to flow from the bushing 106 to the suction duct 134. The frame 110 is secured to the bushing 106 by fastening means (not shown), e.g., screws, bolts, nuts or bolts, or other suitable fastening means. the seal (s) 138 are then mounted on the upper part 132 of the frame 110 as shown and then fitting the mounting collar 140 on the seal O (s) 138 to the protective frame 116 of the fan 108 on the O 25 - so that also the interface between the upper part 132 and the mounting collar 140 7 becomes dense, and the exhaust air 114 is able to flow from the suction duct 134 p to the threat
108. The fastening of the fan 108 to the frame 110 again takes place by fastening means suitable for the purpose E. The frame 110 may comprise, in contrast to the one-piece structure described above, S30 - alternatively a two-piece structure, further comprising an outer frame structure N (outer frame body) 142, the inner frame structure (inner frame body) 144 of the frame 110 now comprising a frame structure 122 and an inner surface structure 124, is removably mountable. The function of the outer frame structure 142 is to protect the inner frame structure 144 from, for example, mechanical shocks and weathering. The outer frame structure 142 also serves to allow the inner frame structure 144 to be pulled out of the frame 110, 5 by an associated pull handle 146 through an opening in the side portion 148 of the outer frame structure 142 for repair or maintenance. The outer frame structure 142 surrounds the inner frame structure 144, as shown, so as not to cover the lower and upper portions 126, 128 of the inner surface structure 124 of the inner frame structure 144, i.e., the suction passage 134, by forming openings in the lower and upper portions 150, 152 of the outer frame structure 142. 154. The profile of the outer frame structure 142 is also square as shown, but may alternatively be rectangular, cylindrical, or some other shape. Regardless of the shape of the profile, the lower portion 150 of the outer frame structure 142 is intended to be mounted against the bushing 106 and the upper portion 152 in turn allows the fan 108 to be mounted thereon. Accordingly, when the inner frame structure 144 is removably mounted within the frame 110, its lower portion 130 abuts the inner surface of the lower portion 150 of the outer frame structure 142, its upper portion 132 against the inner surface of the outer frame structure 142 upper portion 152 and at least a portion thereof against the inner surface of the outer frame structure 142 side portion 148. That portion - the side portion 133 of the inner frame structure 144 that does not abut the inner surface of the outer frame structure 142 together with the side portion 148 of the outer frame structure 142 forms the outer shell of the outer frame structure 142 when the inner frame structure 144 is mounted on the frame 110. .
OO 25 —The installation of the two-part frame 110 in the bushing 106 is performed in a manner similar to the one-piece frame 110 described above. The installation is performed by fitting the frame 110 over the seal (s) 136 so that the upper edge of the bushing 106 and the outer frame structure of the frame 110 The interface between the lower part 150 becomes tight, and the exhaust air 114 is able to flow from the passage 106 to the suction port 304. The seal (s) 138 are then mounted in the outer frame of the frame 110 to the upper part 152 of the structure 142 and in the protective frame 116 of the fan 108. the collar 140 is fitted over the seal (s) 138 so that the interface between the top 152 and the mounting collar 116 also becomes sealed, and the exhaust air 114 is able to flow from the suction duct 134 to the fan 108. The frame 110 and the fan 108 are secured by suitable fastening means.
The function of the protective frame 116 of the fan 100 and the frame structures 122, 142, 144 of the frame 110 is to protect the parts inside them from mechanical shocks and weathering. They are made of sheet metal, which is, for example, aluminum and / or steel.
The guide 112, whether the frame 110 is one-piece or two-piece, is releasably attached to the frame structure 122 in the space 135, allowing it to be easily serviced and repaired.
The guide 112 includes an air intake duct 156 for mounting inside the inner surface structure 124, i.e. the suction duct 134, formed on the rear surface of the inner surface structure 124, for which the inner surface structure 124 has an opening (not shown) for pushing the air intake duct 156 into the inner surface structure 124. By means of the air intake duct 156, a part of the exhaust air 114 entering the suction duct 134 is directed inside the controller 112, where the sensors of its sensor part 264 can make measurements from it. Based on the measurement results, the controller 112 is able to analyze its effect on the need to control the motor 120 based on the large value and behavior to be measured. Based on the analyzed control need, the controller 112 is then able to generate a control command CO to be sent to the motor 120.
The air intake duct 156 is a hollow e.g. tubular, rectangular or polygonal duct with an air intake on the lower surface through which the exhaust air 114 to be taken (captured) from the exhaust air flow 114 can be directed to the air intake duct 156 and along it inside the controller 112. S 25 The controller 112 has an outlet for removing the analyzed air from the controller O 112 back to the suction duct 134. = The air intake duct 156 may comprise one or more air intake ducts as shown, e.g. two, three, four or five air intake ducts 156. [< From the guide 112 it is also possible to pass along the suction channel 134 e.g. measuring tubes used for measuring the pressure difference between the suction chamber and the suction cone of the blower fan 108, the first being placed to measure the suction pressure of the suction chamber and the second the suction pressure of the suction cone.
The controller 112 is connected to the motor 120 by a control connection cable (control cable) 158 output from the frame 110 and externally to the fan 108, and via a safety switch 160 to the voltage supply by a voltage supply cable 162 output from the frame 110 as shown. The controller 112 also includes a temperature sensor for measuring the outdoor temperature and a pressure sensor for measuring the outdoor pressure, which are taken outside the frame 110, the sensor part 264. The controller 112 is encased in a protective housing in the space 135 so that its operability is maintained. The protective housing keeps the air surrounding the controller 112 sufficiently warm or cool according to the weather conditions, and sufficiently dry, and protects the controller 112 from the effects of weather and dirt, and from mechanical shocks. The material of the protective housing is, for example, plastic or metal. Fig. 2 shows the functional parts 264, 266, 268, 270, 272, 274 of the controller 112 connected to the fan 108. A motor 120 is mounted inside the protective frame 116 of the fan 108 to draw the exhaust air 114 from the apartments to the exhaust air duct 104 and a bushing mounted thereon. through a barrel 106 and a suction passage 134 of the frame 110 to a fan 108, where the motor 120 then blows the exhaust air 114 through the structure of the fan 108 out of the building 100. The function of the controller 112 is to make the fan 108 intelligent by analyzing the need for controlling the motor 120 on the basis of at least one sensor measurement of the sensor part 264 in use and, if necessary, controlling the operation of the motor 120 on the basis of the analysis.
O = A control part 266, a sensor part 264 to be used to assist the control z and other functional parts 268, 270, 272, 274 are mounted inside the protective housing of the controller 112. ”The control part 266 is connected to the motor 120 via a connecting cable 158.
O [<] 3 The function of the control automation of the control section 266 for controlling the motor 120 is to control the power of the motor 120 by generating control commands CO> based on the measurement of at least one sensor of the sensor section 264.
The control section 266 includes a processor section 268 for executing instructions defined by the user or an application program and for processing data. The sensor section 264 has at least one sensor, which, based on the measurement of the exhaust air 114 entering the intake duct 134, automatically controls the operation of the motor 120 by the control section 266. At least one sensor of the sensor section 264 can also take measurements of the outside air surrounding the frame 112. The sensor section 264 includes at least one of the following sensors: a temperature sensor for measuring the exhaust air temperature, a temperature sensor for measuring the outside air temperature, a humidity sensor for measuring the humidity of the exhaust air, a carbon dioxide concentration sensor for the exhaust air, a sensor for measuring the VOC gas concentration suction pressure sensors, the measuring tubes of which are inserted inside the protective frame 116 of the fan 108 and the measurement information produced by which can also be used to determine the amount of air. The controller 112 further includes a communication section 270 by means of which the controller 112 receives information via a wireless communication connection from outside the frame 110 (controller 112) and transmits information to the outside via a wireless connection. The communication section 270 comprises, for example, a 3G / 4G wireless network section, by means of which the controller 112 communicates with a device outside the frame 110. The controller 112 may have a physical user interface portion 272 that allows the user to enter commands and information and / or receive information. The user interface part 272 is, for example, a communication interface to which it is possible to connect, by means of a connection cable, e.g. an external computer, a user interface with a display and a keyboard, or an intelligent device with a touch screen.
OO 25 Alternatively, the user can enter commands and information, and / or receive information from his terminal device (not shown in the figures), e.g. a smartphone, tablet computer, laptop computer, desktop computer or the like, and the control software stored therein. via section 270 and at least one telecommunications & communications network. If the terminal is a mobile terminal, e.g. the above-mentioned smartphone, tablet computer, laptop or the like, then the user is also able to control the controller 112 via the communication part 270 and the short-range O radio connection. 5 Alternatively, controller 112 is capable of collecting information related to local weather, air quality, bulletins or the like provided by rescue authorities.
by means of the communication section 270 in the telecommunication network, e.g. the Internet network, and controls the operation of the motor 120 not only on the basis of the measurements made by the sensor section 264 but also on the basis of the information obtained from the telecommunication network. For example, when the local outdoor temperature rises high, as outdoor air pollution increases, or as a result of a large fire indicated by the emergency center bulletin, the controller 112 may control the motor 120 to reduce or increase its power.
The controller 112 further includes a memory portion 274 for storing and storing applications and data. The memory section 274 may comprise at least one memory, e.g.
one, two or three memories.
- The memory section 274 stores a communication application 276 controlling the operation of the communication section 270, the user interface section 272 being a user interface application 278 controlling its operation, an analysis application 280 for processing data from the sensor section 264, and a control application 282 for controlling the operation of the motor 120.
The internal communication required by the controller 112 between the different parts 264, 266, 268, 270, 272, 274 is implemented between a fixed cable connection.
In the memory section 274, predetermined limit values are stored for each quantity to be measured, and when the measurement data from the sensor indicates that the limit value has been exceeded, the analysis application 280 determines whether it must control the operation of the motor 120. The limit values determine whether the power (speed) of the motor 120 is still kept the same, whether it is reduced or increased.
For example, limit values for the temperature can be preset so that when the temperature of the exhaust air 114 decreases below 20 ° C, the controller 112 controls to reduce the power of the motor N 120 to reduce draft in the apartments of the building 100. If, on the other hand, the temperature of the exhaust air 114 exceeds 23 ° C, the controller 112 controls to increase the power of the motor 7 120 to improve ventilation, and if the temperature of the exhaust air is between T 20-23 ° C, the current power of the motor 120 is maintained. The same applies to E other measurands. In addition, the controller 112 is able to deduce the need to increase or decrease the ventilation S based on the preset limit values of two or more measurement variables S30.
O 5 In addition, the analysis application 280 is able to determine the need for ventilation on the basis of two or more measurable large measurement data. For example, the analysis application 280 is able to detect a fire in the exhaust air 114 in the building 100 by analyzing measurement data from VOC, carbon dioxide, temperature, and humidity sensors, and based on the analysis, the controller 112 controls the motor 120 to enhance smoke removal. In addition, upon detecting the fire, the controller 112 may wirelessly provide information to the communication section 270, i.e., make a fire alarm, to another external terminal. The operation of the fan 108 can be monitored and / or controlled in real time via a wireless communication connection (network) by means of a terminal using a browser-based control software for controlling the fan 108, as described above. Through the control software of the terminal it is possible to - monitor the operation of the fan 108, or several fans 108, by examining the measurement data from the different sensors of each controller 112 and the analysis data made therefrom, receive notifications, e.g. a fire alarm, and manually control the operation of the fans 108. The exhaust system of an entire large building 100 with a plurality of fans 108 upgraded by the controller 112 of the frame 110 may be arranged so that the controllers 112 communicate with each other wirelessly via the communication portions 270 and one of the controllers 112 acts as the main controller through which all other controllers 112 send information via at least one telecommunication network to an external terminal, e.g. a control server (not shown in the figures). Through the main controller 112, all other controllers 112 also receive information received via at least one telecommunication network, by means of which they are controlled. The control server is able to use the control software to collect N25 information related to local weather, air quality, rescue services bulletins or the like in the telecommunication network (s), e.g. the Internet, and to direct it to the exhaust air system N based on the information obtained therefrom. For example, based on information obtained from the telecommunications network, e.g., local outdoor temperature rise, outdoor air pollution, or emergency = central bulletin, the control server may control each exhaust air system controller 112 via main controller 112 to reduce or increase the power of motor 120.
