The adapter (400) connects the air-conditioning blowout port (320) and a ceiling opening (122) provided in the ceiling of the common space (14). The adapter (400) suppresses leakage of the air-conditioned air (210) into the common space (14).

Description

Air conditioning systems, adapters

[0001] The present disclosure relates to air conditioning technology, and more particularly to an air conditioning system and an adapter for controlling air conditioning in multiple rooms.

[0002] In a house, an air conditioner is installed in a common space facing each room, such as a hallway. The air conditioner cools and heats the common space, providing air conditioning to maintain a comfortable temperature environment in the common space. Furthermore, installing a circulator or the like in the common space to agitate the airflow and make the temperature more uniform results in less uneven air conditioning in each room and a more stable temperature environment (see, for example, Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2021-148382

[0004] Using a common space as an air-conditioned room and a general-purpose air conditioner minimizes the reduction in effective floor area and the increase in costs compared to installing a dedicated air conditioner in a dedicated air-conditioned room. However, using a general-purpose air conditioner makes it difficult to supply air that is blown diagonally downward to each room. Furthermore, using a common space as an air-conditioned room increases the temperature difference between the common space and each room, reducing comfort.

[0005] The present disclosure has been made in consideration of these circumstances, and its purpose is to provide a technology that suppresses a decrease in air conditioning efficiency even when an air conditioner is installed in a shared space.

[0006] In order to solve the above problems, an air conditioning system according to one embodiment of the present disclosure includes an air conditioner that is installed on a wall of a common space adjacent to the rooms that make up the living space, and that draws in air from the common space through an air conditioning intake and blows out conditioned air from an air conditioning outlet, and an adapter that connects the air conditioning outlet to a ceiling opening provided in the ceiling of the common space and prevents conditioned air from leaking into the common space.

[0007] Another aspect of the present disclosure is an adapter that connects an air conditioning outlet of an air conditioner that is installed in a wall of a common space adjacent to a room that constitutes a living space and that draws in air from the common space through an air conditioning inlet and blows out conditioned air through an air conditioning outlet, with a ceiling opening provided in the ceiling of the common space.

[0008] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc., are also valid aspects of the present disclosure.

[0009] According to the present disclosure, even when an air conditioner is installed in a common space, a decrease in air conditioning efficiency can be suppressed.

[0011] Before describing specific embodiments of the present disclosure, an overview of the embodiments will be provided. This embodiment relates to an air conditioning system that performs whole-house air conditioning in a home having a common space and multiple living rooms. The air conditioning system does not use dedicated air-conditioning rooms and dedicated air conditioners to prevent a reduction in effective area and an increase in costs. Therefore, the air conditioning system installs general-purpose air conditioners in common spaces, such as hallways, and uses the common spaces as air-conditioning rooms. Furthermore, a transport fan is installed in a ceiling opening in the common space, and the transport fan transports air from the common space to each living room via ducts. In such a situation, as described above, it is difficult to supply air blown diagonally downward to each living room, and comfort is reduced due to the increased temperature difference between the common space and each living room. To address these issues, the air conditioning system includes an adapter attached to the air conditioner that covers at least the bottom and front of the air conditioner and directs air blown downward from the air conditioner to the ceiling opening.

[0012] The examples described below each illustrate a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component placement and connection configurations, steps (processes), and step order shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, components that are not described in the independent claims that represent the highest concept of the present disclosure are described as optional components. Furthermore, in each figure, substantially identical components are designated by the same reference numerals, and redundant descriptions are omitted or simplified.

[0013] The following describes the embodiment in the order of (1) overall configuration, (2) adapter and peripheral configuration, and (3) air volume control.

[0014] (1) Overall Configuration FIG. 1 is a top view showing the configuration of a house 500 in which an air conditioning system 1000 is installed, and FIG. 2 is a cross-sectional view showing the configuration of the house 500 in which the air conditioning system 1000 is installed. The house 500 may be a single-family residence in an apartment building or other multi-family housing complex, or may be a detached house. The house 500 includes first living rooms 10a to fourth living rooms 10d, collectively referred to as living rooms 10, and a common space 14. The living rooms 10 constitute living spaces where people stay for long periods of time. The common space 14 is a space where people stay for shorter periods of time than living spaces such as corridors, hallways, and storage spaces such as closets, and is adjacent to the living rooms 10. The common space 14 and the living rooms 10 are connected to each other for ventilation, allowing air to circulate from each living room 10 to the common space 14.

[0015] The air conditioning system 1000 includes an outside air inlet 100, an outside air introduction duct 102, a heat exchange ventilation fan 104, an exhaust duct 106, an exhaust port 108, a heat exchange duct 110, a heat exchange outlet 112, a transport fan 120, a transport duct 130, a branch chamber 140, a first branch transport duct 142a to a seventh branch transport duct 142g collectively referred to as branch transport ducts 142, a first outlet 144a to a seventh outlet 144g collectively referred to as outlets 144, an air conditioner 300, and an adapter 400. The outside air introduction duct 102, the exhaust duct 106, the heat exchange duct 110, the transport duct 130, and the branch transport ducts 142 are pipes that transport air, that is, air paths.

[0016] The outside air inlet 100 is installed on a wall surface of the house 500. An outside air inlet duct 102 extending from the outside air inlet 100 toward the interior of the house 500 is connected to a heat exchange type ventilation fan 104. The heat exchange type ventilation fan 104 is disposed, for example, in the attic 16 of the common space 14. An exhaust duct 106 is also connected to the heat exchange type ventilation fan 104, and the exhaust duct 106 extends toward the wall surface of the house 500 and is connected to an exhaust port 108 installed on the south wall surface. A heat exchange duct 110 is also connected to the heat exchange type ventilation fan 104.

[0017] The heat exchange ventilation fan 104 takes in outside air 200 from the outside air inlet 100 through the outside air inlet duct 102. The outside air 200 drawn in through the outside air inlet 100 corresponds to supply air. The heat exchange ventilation fan 104 also takes in ventilation return air (RA) 202 through a ventilation opening (not shown). The ventilation RA 202 is indoor air flowing in from the interior of the house 500, for example, from rooms including the living room 10 and the common space 14. The heat exchange ventilation fan 104 exchanges heat between these air sources. As a result of the heat exchange, the heat exchange ventilation fan 104 discharges exhaust air 204 from the exhaust outlet 108 through the exhaust duct 106. The heat exchange ventilation fan 104 also discharges the heat-exchanged supply air 208 (outside air 200) through the heat exchange duct 110 and the heat exchange outlet 112. The heat exchanger outlet 112 is an opening provided in the ceiling of the common space 14. In other words, the heat exchanger ventilation fan 104 blows supply air 208 (heat exchange supply air), which is outside air 200 that has exchanged heat with ventilation RA 202 exhausted from the living space, from the heat exchanger outlet 112 into the common space 14. Note that if heat exchange between the ventilation RA 202 and the outside air 200 is sufficient, the heat exchanger outlet 112 may be configured to be connected to a transport fan 120, which will be described later. With this configuration, the supply air 208 can be reliably sent to the transport fan 120 without passing through the common space 14.

[0018] The air conditioner 300 is not installed in a dedicated air-conditioning room, but is installed on a wall (not shown) of the common space 14. An air conditioning inlet 310 is provided at the top end of the air conditioner 300. A heat exchanger outlet 112 is provided vertically above the air conditioner 300, and supply air 208 blown out from the heat exchanger outlet 112 flows into the air conditioning inlet 310. Circulating RA 206 also flows into the air conditioning inlet 310 from the common space 14, which is the interior of the house 500. Like the ventilation RA 202, the circulating RA 206 corresponds to supply air that has traveled within the house 500. The air conditioner 300 is a general-purpose air conditioner and performs air conditioning on the circulating RA 206 and the supply air 208. The air conditioner 300 controls the temperature, humidity, etc. of the circulating RA 206 and the supply air 208 so that they reach a set temperature (hereinafter referred to as the "set temperature"). An air conditioning outlet 320 is provided at the bottom end of the air conditioner 300, and the air conditioner 300 blows out conditioned air (conditioned air 210) from the air conditioning outlet 320. In other words, the air conditioner 300 draws in air from the common space 14 through the air conditioning inlet 310 and blows out the conditioned air 210 from the air conditioning outlet 320.

[0019] A ceiling opening 122 is provided in the ceiling of the common space 14. A transport fan 120 installed in the attic 16 draws in conditioned air 210 and circulating RA 206 (hereinafter, these may be referred to as "conditioned air 210") through the ceiling opening 122. The transport fan 120 is connected to the branch chamber 140 via a transport duct 130, and transports the conditioned air 210 to the branch chamber 140.

[0020] The branch chamber 140 is installed in the ceiling space 16 and is connected to the transport fan 120 as well as the first to seventh branch transport ducts 142a to 142g. The first branch transport duct 142a is connected to the first air outlet 144a installed in the first living room 10a, and the second branch transport duct 142b is connected to the second air outlet 144b installed in the second living room 10b. The third branch transport duct 142c is connected to the third air outlet 144c installed in the third living room 10c, and the fourth branch transport duct 142d is connected to the fourth air outlet 144d installed in the fourth living room 10d. The fifth branch transport duct 142e is connected to the fifth air outlet 144e installed in the first living room 10a, and the sixth branch transport duct 142f is connected to the sixth air outlet 144f installed in the second living room 10b. The seventh branch conveying duct 142g is connected to a seventh air outlet 144g installed in the fourth room 10d.

[0021] The transport fan 120 transports the conditioned air 210 from the first room 10a to the fourth room 10d via the transport duct 130, the branch chamber 140, the first branch transport duct 142a to the seventh branch transport duct 142g, and the first air outlet 144a to the seventh air outlet 144g. Each air outlet 144 is installed on the side wall or ceiling of each room 10 and discharges the conditioned air 210 blown from the transport fan 120 into each room 10. Since each room 10 is connected to the common space 14, the conditioned air 210 blown out from the air outlet 144 also circulates in the common space 14. A portion of the circulating air flows into the air conditioner 300 as circulating air RA 206. The circulating air 206 may also flow into the transport fan 120 through the ceiling opening 122. Furthermore, another part of the circulating air is taken into the heat exchange type ventilation fan 104 as ventilation air RA 202.

[0022] If the conditioned air 210 blown out from the air conditioning outlet 320 of the air conditioner 300 diffuses into the common space 14, the amount of conditioned air 210 drawn into the conveying fan 120 through the ceiling opening 122 decreases. This reduces the amount of conditioned air 210 supplied to each room 10, thereby reducing air conditioning efficiency. To prevent this reduction in air conditioning efficiency, in this embodiment, as shown in FIG. 2 , an adapter 400 is installed in the common space 14. The adapter 400 connects the air conditioning outlet 320 and the ceiling opening 122, preventing leakage of the conditioned air 210 into the common space 14. When leakage of the conditioned air 210 into the common space 14 is reduced, the reduction in the amount of conditioned air 210 drawn into the conveying fan 120 through the heat exchanger outlet 112 is also reduced.

[0023] (2) Configuration of the Adapter and Its Surrounding Areas FIG. 3 shows the configuration of the air conditioner 300 and the adapter 400. FIG. 9 shows a side view of the positional relationship between the air conditioner 300, the adapter 400, and the ceiling opening 122, and FIG. 10 shows a side view of the positional relationship between the air conditioner 300 and the heat exchange duct 110. As described above, the air conditioner 300 is installed on the wall of the common space 14. An air conditioning intake 310 is disposed at the upper end of the air conditioner 300, and an air conditioning outlet 320 is disposed at the lower end of the air conditioner 300. A heat exchange outlet 112 and a ceiling opening 122 are provided on the ceiling of the common space 14. For example, the heat exchange outlet 112 and the air conditioning intake 310 face each other. As shown in FIG. 10, the heat exchange duct 110 may be extended from the ceiling so that the heat exchange outlet 112 and the air conditioning intake 310 are positioned on approximately the same plane. In other words, the tip of the heat exchange duct 110 may be in contact with the upper end of the air conditioner 300. With this configuration, it is possible to prevent the supply air 208 (heat exchange supply air) from diffusing into the common space 14, and to condition the entire amount of the supply air 208 by the air conditioner 300 before supplying it to each room.

[0024] The adapter 400 includes a leak-proof bottom surface 402, a leak-proof top surface 404, and a first leak-proof side surface 406a and a second leak-proof side surface 406b, collectively referred to as leak-proof sides 406. The leak-proof bottom surface 402 is positioned vertically below the air conditioner 300, covering at least a portion of the air conditioning outlet 320, and extends upward toward the ceiling in a curved manner. In this manner, the leak-proof bottom surface 402 includes not only a flat surface but also a curved surface. The leak-proof top surface 404 faces the leak-proof bottom surface 402 and is positioned between the air conditioner 300 and the ceiling of the common space 14.

[0025] The first leak prevention side surface 406a and the second leak prevention side surface 406b are connected to the leak prevention bottom surface 402 and the leak prevention top surface 404 and are arranged opposite each other. The first leak prevention side surface 406a has a first notch 407a, where the upper portion facing the air conditioner 300 is missing, and the second leak prevention side surface 406b has a second notch 407b, where the upper portion facing the air conditioner 300 is missing. The first notch 407a and the second notch 407b are collectively referred to as notch 407. The notch 407 allows the adapter 400 to be fixed in place with the air conditioning intake 310 exposed to the common space 14.

[0026] 3 and 9 , the space surrounded by the leak-proof bottom surface 402, the leak-proof top surface 404, the first leak-proof side surface 406 a, and the second leak-proof side surface 406 b is the ventilation space 408, which is spatially independent from the common space 14. The downstream ends of the leak-proof bottom surface 402, the leak-proof top surface 404, the first leak-proof side surface 406 a, and the second leak-proof side surface 406 b are connected to the ceiling of the common space 14 while surrounding the ceiling opening 122.

[0027] Furthermore, the upstream ends of the leak-preventing bottom surface 402, the leak-preventing top surface 404, the first leak-preventing side surface 406a, and the second leak-preventing side surface 406b surround and cover the air conditioning outlet 320. In other words, the upstream end of the leak-preventing bottom surface 402 is located below the air conditioning outlet 320, and the upstream end of the leak-preventing top surface 404 is located above the air conditioning outlet 320. Furthermore, when viewing the air conditioner 300 from the front, the upstream end of the first leak-preventing side surface 406a is located to the left of the air conditioning outlet 320, and the upstream end of the second leak-preventing side surface 406b is located to the right of the air conditioning outlet 320. With this configuration, the conditioned air 210 blown out from the air conditioning outlet 320 is guided through the air supply space 408 to the ceiling opening 122. In other words, the conditioned air 210 can be prevented from diffusing into the common space 14. The upstream end of the leak prevention top surface 404 may be configured to abut against the air conditioner 300 above the air conditioning outlet 320. This configuration can further prevent the conditioned air 210 guided to the ceiling opening 122 from leaking from the air supply space 408 into the common space 14. The upstream ends of the leak prevention bottom surface 402, the first leak prevention side surface 406a, and the second leak prevention side surface 406b may also abut against the air conditioner 300.

[0028] The supply air 208 blown out from the heat exchanger outlet 112 is drawn into the air conditioning intake 310 of the air conditioner 300. Furthermore, the circulating air RA 206 in the common space 14 passes through the first notch 407a in the first leakage prevention side surface 406a or the second notch 407b in the second leakage prevention side surface 406b and is drawn into the air conditioning intake 310 of the air conditioner 300. Furthermore, the conditioned air 210 blown out from the air conditioning outlet 320 of the air conditioner 300 passes through the air supply space 408 and is mainly guided to the ceiling opening 122.

[0029] The leak-preventing bottom surface 402 has a streamlined design that runs from the air conditioning outlet 320 toward the ceiling opening 122 so that the conditioned air 210 blown out from the air conditioning outlet 320 can be quickly sucked into the ceiling opening 122. Note that a shape other than a streamlined design may be used as long as it is possible to guide the conditioned air 210 to the ceiling opening 122; for example, the leak-preventing bottom surface 402 may have a bent shape rather than a curved shape. The leak-preventing top surface 404 can also be considered an air path separation plate that prevents the conditioned air 210 blown out from the air conditioning outlet 320 from going to the air conditioning inlet 310.

[0030] 4A-4D are diagrams showing the configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140. FIG. 4A shows the configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140 when viewed obliquely from above, and FIG. 4B shows the cross-sectional configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140 when viewed obliquely from above. FIG. 4C shows the configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140 when viewed from the side, and FIG. 4D shows the cross-sectional configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140 when viewed from above. The transport duct 130, which has been omitted up until now, is connected to the transport fan 120 and the branch chamber 140 and guides the conditioned air 210 from the transport fan 120 to the branch chamber 140.

[0031] The downstream end of the adapter 400 is fixed to the ceiling by a downstream end fixing part 410. The downstream end fixing part 410 is, for example, an L-shaped metal fitting, and is fixed to the downstream end of the adapter 400 and the ceiling using screws or the like. The downstream end fixing part 410 is preferably fixed to the ceiling to prevent air from directly entering the ceiling opening 122 from the common space 14, but it may also be detachable.

[0032] The upstream end of the adapter 400 is fixed to at least one of the wall or the air conditioner 300 by an upstream end fixing part 412. The upstream end fixing part 412 is also, for example, an L-shaped metal fitting, and is fixed to at least one of the wall or the air conditioner 300 and the upstream end of the adapter 400 using screws or the like. The upstream end fixing part 412 may also be detachable.

[0033] The upstream side of the leakage-preventing top surface 404, i.e., the end on the air conditioner 300 side, is called the top surface upstream end 416, and an inlet opening 414 is formed between the top surface upstream end 416 and the air conditioner 300. The inlet opening 414 is an opening for allowing the circulating air 206 in the common space 14 to flow into the air supply space 408. If the air volume of the transport fan 120 is greater than the air volume of the air conditioner 300, the load on the air conditioner 300 increases. The inlet opening 414 is provided to reduce the load on the air conditioner 300. Furthermore, the inlet opening 414 is positioned below the top surface upstream end 416 and the air conditioning intake 310 to avoid short circuits. Furthermore, the leakage-preventing top surface 404 may be provided with an inlet opening adjustment unit for adjusting the size of the inlet opening 414. The inlet opening adjustment unit is, for example, a shutter that slides along the leakage-preventing top surface 404. When the load of the air conditioner 300 is small, the inlet opening 414 may be fully closed by the inlet opening adjustment unit, and the top surface upstream end 416 may be brought into contact with the air conditioner 300 .

[0034] An openable / closable opening / closing panel 420 is provided on the leak-preventing bottom surface 402. By opening the opening / closing panel 420, a maintenance opening 418 on the leak-preventing bottom surface 402 is exposed. The maintenance opening 418 is an opening for performing maintenance on the air conditioner 300 while the adapter 400 is connected to the air conditioner 300. For example, the air conditioner 300 can be maintained with a vacuum cleaner through the maintenance opening 418.

[0035] A first filter 422a is attached to the first cutout 407a, and a second filter 422b is attached to the second cutout 407b. Therefore, the first filter 422a is provided on approximately the same plane as the first leakage prevention side surface 406a, and the second filter 422b is provided on approximately the same plane as the second leakage prevention side surface 406b. The first filter 422a and the second filter 422b are collectively referred to as filter 422. The filter 422 purifies the circulating air 206 drawn from the common space 14 into the air conditioning intake 310 upstream of the air conditioning intake 310. This configuration allows the interior of the air conditioner 300 to be kept clean, reducing the frequency of maintenance of the air conditioner 300 performed through the maintenance opening 418.

[0036] A first ventilation gap 424a is arranged between the first filter 422a and the side surface of the air conditioner 300, and a second ventilation gap 424b is arranged between the second filter 422b and the side surface of the air conditioner 300. The first ventilation gap 424a and the second ventilation gap 424b are collectively referred to as the ventilation gap 424. The ventilation gap 424 is a gap for ventilating the circulating air 206 in the common space 14 that has passed through the filter 422 to the air conditioning intake 310. Such ventilation gaps 424 ensure the effective area of ​​the filter 422.

[0037] (3) Air Volume Control Below, the control of the air volume of the air conditioner 300 (hereinafter referred to as "air conditioning air volume") and the air volume of the conveying fan 120 (hereinafter referred to as "fan air volume") will be described in the order of (3-1) First Configuration, (3-2) Second Configuration, and (3-3) Third Configuration. Also, the control of the air volume of the conveying fan 120 and the air volume of the heat exchange type ventilation fan 104 (hereinafter referred to as "heat exchange supply air volume") will be described in (3-4) Fourth Configuration. Note that below, as an example, one controller that controls the air conditioner 300 and the conveying fan 120 is illustrated. If it is possible to control the respective air volumes, a configuration may be used in which a controller for controlling the air conditioner 300 and a controller for controlling the conveying fan 120 are provided separately.

[0038] (3-1) First Configuration In the first configuration, the air conditioning airflow rate of the air conditioner 300 is adjusted in accordance with the fan airflow rate of the conveying fan 120. FIGS. 5A-B show a first configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 5A, the air conditioning system 1000 includes the conveying fan 120, the air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 also includes a room temperature acquisition unit 462, a fan airflow rate control unit 466, a fan airflow rate acquisition unit 468, and an air conditioning airflow rate control unit 472.

[0039] The temperature sensor 450 is installed in the living room 10 and detects the temperature of the living room 10 (hereinafter referred to as "living room temperature"). The temperature sensor 450 has a communication function such as wireless communication, and transmits the detected living room temperature to the controller 460. The transport fan 120 transmits the set fan air volume of the transport fan 120 to the controller 460.

[0040] The controller 460 is installed in the house 500 in FIGS. 1 and 2 . The controller 460 controls the entire air conditioning system 1000. The controller 460 is communicably connected to the conveying fan 120, the air conditioner 300, and the temperature sensor 450 via wireless communication. At least some of these may be communicably connected via wired communication. The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The fan airflow rate acquisition unit 468 acquires the fan airflow rate by receiving the fan airflow rate setting from the conveying fan 120. The fan airflow rate may be acquired from the conveying fan 120 or from the fan airflow rate control unit 466.

[0041] The fan airflow control unit 466 receives the room temperature from the room temperature acquisition unit 462. FIG. 5B is an example of a table stored in the fan airflow control unit 466. As shown in the figure, room temperatures correspond to fan airflow rates. The fan airflow control unit 466 determines the fan airflow rate by referencing the table based on the acquired room temperature. Return to FIG. 5A . In this case, if the determined fan airflow rate is lower than the air-conditioning airflow rate, the air-conditioning airflow control unit 472 sets the air-conditioning airflow rate equal to or lower than the fan airflow rate. The air-conditioning airflow control unit 472 adjusts the air-conditioning airflow rate of the air conditioner 300 by transmitting the determined air-conditioning airflow rate to the air conditioner 300. Here, "setting the air-conditioning airflow rate equal to or lower than the fan airflow rate" also includes making the air-conditioning airflow rate equal to the fan airflow rate. By making the fan airflow rate and the air-conditioning airflow rate acquired by the fan airflow acquisition unit 468 equal, the conditioned air 210 can be delivered to each room while reducing the load on the air conditioner 300.

[0042] (3-2) Second Configuration In the second configuration, the fan airflow rate of the conveying fan 120 is adjusted in accordance with the air conditioning airflow rate of the air conditioner 300. FIGS. 6A-B show a second configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 6A, the air conditioning system 1000 includes the conveying fan 120, the air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 also includes a room temperature acquisition unit 462, an air conditioning temperature control unit 470, an air conditioning airflow control unit 472, an air conditioning airflow rate acquisition unit 464, and a fan airflow control unit 466. The temperature sensor 450 detects the room temperature of the room 10 and transmits the detected room temperature to the controller 460. The air conditioner 300 transmits the set air conditioning airflow rate of the air conditioner 300 to the controller 460.

[0043] The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The air conditioning airflow acquisition unit 464 acquires the air conditioning airflow by receiving the air conditioning airflow setting from the air conditioner 300. The air conditioning airflow may be acquired from the air conditioner 300 or from the air conditioning airflow control unit 472. The air conditioning temperature control unit 470 receives the room temperature from the room temperature acquisition unit 462. The air conditioning temperature control unit 470 also receives the set temperature of the air conditioner 300 from an operation unit (not shown). The air conditioning temperature control unit 470 determines the temperature of the air conditioner 300 (hereinafter referred to as the "air conditioning temperature") based on the room temperature and the set temperature. Known techniques may be used to determine the air conditioning temperature; for example, the air conditioning temperature is determined so that the room temperature is close to the set temperature. The air conditioning temperature control unit 470 adjusts the air conditioning temperature of the air conditioner 300 by transmitting the determined air conditioning temperature to the air conditioner 300 .

[0044] The air conditioning airflow control unit 472 receives the room temperature from the room temperature acquisition unit 462. FIG. 6B shows an example of a table stored in the air conditioning airflow control unit 472. As shown, room temperatures correspond to air conditioning airflow rates. The air conditioning airflow control unit 472 determines the air conditioning airflow rate by referencing the table based on the acquired room temperature. Returning to FIG. 6A , if the determined air conditioning airflow rate is greater than the fan airflow rate, the fan airflow control unit 466 adjusts the fan airflow rate of the transport fan 120 by transmitting the determined fan airflow rate to the transport fan 120. Here, "making the fan airflow rate greater than or equal to the air conditioning airflow rate" also includes making the fan airflow rate equal to the air conditioning airflow rate. By making the air conditioning airflow rate acquired by the air conditioning airflow acquisition unit 464 equal to the fan airflow rate, the conditioned air 210 can be delivered to each room while reducing the load on the air conditioner 300.

[0045] (3-3) Third Configuration In the third configuration, the fan air volume of the transport fan 120 and the air conditioning air volume of the air conditioner 300 are adjusted together. FIGS. 7A-B show a third configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 7A, the air conditioning system 1000 includes the transport fan 120, the air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 also includes a room temperature acquisition unit 462 and an air volume control unit 474. The temperature sensor 450 detects the room temperature of the room 10 and transmits the detected room temperature to the controller 460.

[0046] The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The air volume control unit 474 receives the room temperature from the room temperature acquisition unit 462. FIG. 7B is an example of a table stored in the air volume control unit 474. As shown in the figure, air conditioning air volumes and fan air volumes are associated with room temperatures. Here, the fan air volume is set to be equal to or greater than the air conditioning air volume for the same room temperature. The air volume control unit 474 determines the air conditioning air volume and fan air volume by referencing the table based on the acquired room temperature. The air volume control unit 474 transmits the determined air conditioning air volume to the air conditioner 300 and the determined fan air volume to the transport fan 120, thereby adjusting the air conditioning air volume of the air conditioner 300 and the fan air volume of the transport fan 120.

[0047] (3-4) Fourth Configuration In the fourth configuration, the fan airflow rate of the transport fan 120 is adjusted in accordance with the heat exchanger supply airflow rate of the heat exchanger ventilation fan 104. FIGS. 8A-B show a fourth configuration of the controller 460 in the air conditioning system 1000. As shown in FIGS. 8A and 8B, the air conditioning system 1000 includes the heat exchanger ventilation fan 104, the transport fan 120, and the controller 460. The controller 460 also includes a heat exchanger supply airflow rate storage unit 478, a heat exchanger supply airflow rate acquisition unit 476, and a fan airflow rate control unit 466a.

[0048] The heat exchanger supply air volume memory unit 478 stores the setting of the heat exchanger supply air volume generated by the heat exchanger ventilation fan 104. The heat exchanger supply air volume memory unit 478 stores the setting of the heat exchanger ventilation fan 104 that was set according to the size of the house 500 at the time of construction, for example.

[0049] The heat exchanger supply air volume acquisition unit 476 acquires the heat exchanger supply air volume by receiving the heat exchanger supply air volume setting from the heat exchanger ventilation fan 104. Note that the heat exchanger supply air volume setting stored in the heat exchanger supply air volume storage unit 478 may be received as shown in FIG. 8B .

[0050] The fan airflow control unit 466a controls the transport fan 120 based on the heat exchanger supply airflow rate received from the heat exchanger supply airflow rate acquisition unit 476. When the heat exchanger supply airflow rate is greater than the fan airflow rate, the fan airflow rate control unit 466a sets the fan airflow rate to be equal to or greater than the heat exchanger supply airflow rate. The fan airflow rate control unit 466a adjusts the fan airflow rate of the transport fan 120 by transmitting the determined fan airflow rate to the transport fan 120.

[0051] The fourth configuration is a method for controlling the lower limit of the fan airflow, and is effective as a means for ensuring the fan airflow required to supply all of the supply air 208 to each room even when the air conditioner 300 is stopped and the air conditioning airflow drops to zero during the spring and fall seasons. Therefore, by using this configuration in combination with the (3-1) first configuration, (3-2) second configuration, and (3-3) third configuration, it becomes possible to control the airflow of each device to perform necessary and sufficient air conditioning and ventilation throughout the year.

[0052] The subject of the device, system, or method of the present disclosure includes a computer. The computer executes a program to realize the functions of the subject of the device, system, or method of the present disclosure. The computer includes, as its main hardware configuration, a processor that operates according to the program. The type of processor is not important as long as it can realize the functions by executing the program. The processor is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into a single chip or may be provided on multiple chips. The multiple chips may be integrated into a single device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium, such as a computer-readable ROM, an optical disc, or a hard disk drive. The program may be pre-stored on the recording medium or may be supplied to the recording medium via a wide area communication network, including the Internet.

[0053] According to this embodiment, the adapter 400 connects the air conditioning outlet 320 of the air conditioner 300 with the ceiling opening 122 provided in the ceiling of the common space 14, thereby suppressing leakage of the conditioned air 210 into the common space 14, thereby suppressing a decrease in air conditioning efficiency even when the air conditioner 300 is installed in the common space 14. Furthermore, the use of the adapter 400 makes it possible to supply air blown obliquely downward to each living room 10 even when a general-purpose air conditioner 300 is used. Furthermore, the use of the adapter 400 makes it possible to suppress an increase in the temperature difference between the common space 14 and each living room 10 even when the common space 14 is used as an air-conditioned room. Furthermore, because the temperature difference between the common space 14 and each living room 10 is suppressed from increasing, a decrease in comfort is suppressed.

[0054] Furthermore, because the transport fan 120 is in communication with the ceiling opening 122 and transports the conditioned air 210 to the room 10, the adapter 400 can efficiently transport the conditioned air 210 from the air conditioner 300. Furthermore, because the adapter 400 has an air flow space 408 surrounded by a leakage-preventing bottom surface 402, a leakage-preventing top surface 404, and two leakage-preventing side surfaces 406, leakage of the conditioned air 210 into the common space 14 can be suppressed. Furthermore, because the downstream end fixing portion 410 fixes the downstream end of the adapter 400 to the ceiling, leakage of the conditioned air 210 into the common space 14 can be suppressed. Furthermore, because the upstream end fixing portion 412 fixes the upstream end of the adapter 400 to at least one of the wall and the air conditioner 300, leakage of the conditioned air 210 into the common space 14 can be suppressed.

[0055] Furthermore, because the adapter 400 is fixed with the air conditioning intake 310 exposed to the common space 14, the circulating RA 206 in the common space 14 can be drawn into the air conditioning intake 310. Furthermore, because the leakage prevention top surface 404 is provided with an inlet opening 414, the circulating RA 206 is allowed to flow into the air supply space 408, thereby suppressing an increase in the load on the air conditioner 300. Furthermore, because the size of the inlet opening 414 is adjusted by the inlet opening adjustment unit, the amount of circulating RA 206 allowed to flow into the air supply space 408 can be adjusted. Furthermore, because the air conditioning intake 310 is provided at the top end of the air conditioner 300 and the inlet opening 414 is located at the upstream end of the leakage prevention top surface 404 and below the air conditioning intake 310, the occurrence of a short circuit can be avoided.

[0056] Furthermore, the leak-prevention bottom surface 402 includes a maintenance opening 418 and an opening / closing panel 420, allowing maintenance of the air conditioner 300 to be performed while the adapter 400 remains attached to the air conditioner 300. Furthermore, the filter 422 allows for purification of the circulating RA 206. Furthermore, a ventilation gap 424 is provided between the filter 422 and the air conditioner 300, ensuring an effective surface area for the filter 422. Furthermore, the heat exchange ventilation fan 104 blows the supply air 208 from the heat exchange outlet 112 into the common space 14, thereby reducing the temperature difference between the common space 14 and the supply air 208. Furthermore, the heat exchange outlet 112 is located vertically above the air conditioner 300, allowing the supply air 208 to be efficiently drawn into the conditioned air 210.

[0057] Furthermore, since the fan airflow rate is adjusted based on the room temperature, a fan airflow rate appropriate for the room temperature can be used. Furthermore, since the fan airflow rate is set to be equal to or greater than the air-conditioning airflow rate, an increase in the load on the air conditioner 300 can be suppressed. Furthermore, since the air-conditioning airflow rate is controlled based on the room temperature, a fan airflow rate appropriate for the room temperature can be used. Furthermore, since the air-conditioning airflow rate is set to be equal to or less than the fan airflow rate, an increase in the load on the air conditioner 300 can be suppressed. Furthermore, since the fan airflow rate and the air-conditioning airflow rate are controlled so that the fan airflow rate is equal to or greater than the air-conditioning airflow rate, a fan airflow rate and air-conditioning airflow rate appropriate for the environment can be used while suppressing an increase in the load on the air conditioner 300.

[0058] In the embodiment of the present disclosure, as an example, a case has been described in which the air conditioner 300 is installed in a hallway, which is a common space 14, as shown in Figure 1, but the installation location of the air conditioner 300 is not limited to the hallway. It may be installed anywhere in the common space 14 adjacent to the living rooms 10 that make up the living space. For example, as shown in Figure 11, the air conditioner 300 and adapter 400 may be installed above a storage space 520 adjacent to a certain living room 10e. Here, Figure 11 is a schematic diagram showing a configuration in which the air conditioner 300 and branch chamber 140 are installed in the storage space 520.

[0059] 11 , the corridor 510 is the common space 14 and is adjacent to each room including the living room 10e in a manner that allows ventilation. The storage space 520 is also the common space 14 and is adjacent to one of the living rooms 10e in a manner that allows ventilation. The corridor 510 and the storage space 520 are adjacent to each other, separated by a wall 534 that cannot be opened or closed.

[0060] A certain living room 10e and the storage space 520 are adjacent to each other across a door 532. The door 532 can be opened and closed, and connects the common space 14 and the living room 10 to each other in a manner that allows ventilation.

[0061] Storage space 520 is divided into an upper section and a lower section by storage top panel 521, which is provided parallel to the floor. The space above storage top panel 521 is referred to as storage compartment 522, and the space below storage top panel 521 is referred to as storage compartment 523. In Figure 12, air conditioner 300 and adapter 400 are installed in storage compartment 522, which is the upper section of storage space 520.

[0062] In this configuration, air from each living room first flows into a certain living room 10e via the corridor 510. Then, the air from each living room is ventilated to the storage space 520 via the certain living room 10e and can be conditioned by the air conditioner 300. The conditioned air is guided via the adapter 400 to the transport fan 120 in the attic 16 and transported to each living room. Note that a ventilation opening 536, which is an opening that allows ventilation between the storage space 520 and the corridor 510, may be provided in the wall 534. With this configuration, the air from each living room that has been ventilated into the corridor 510 can be taken directly from the corridor 510 into the storage space 520 and conditioned there.

[0063] Furthermore, in the embodiment of the present disclosure, a case where conditioned air 210 is transported from the attic space 16 side to the room 10 as shown in FIG. 2 has been described as an example, but the present disclosure is not limited to this configuration. For example, as shown in FIG. 12 , a communication duct 135 that connects the attic space 16 and the underfloor space 17 may be installed to transport conditioned air 210 from the underfloor space 17 side to the room 10. Here, FIG. 12 is a schematic diagram showing a configuration where conditioned air 210 is transported using the underfloor space 17. In FIG. 12 , the transport fan 120 is located in the attic space 16, and the branch chamber 140 is located underfloor space 17. In FIG. 12 , a communication duct 135 is further provided as an air path for the air conditioning system 1000.

[0064] The communication duct 135 is an air passage that connects the attic 16, which is a space located above the ceiling of the common space 14, with the underfloor 17, which is a space located below the floor of the common space. One end of the communication duct 135 is connected to the outlet of the transport fan 120 installed in the attic 16, and the other end is connected to the branch chamber 140 installed in the underfloor 17. With this configuration, the conditioned air 210 blown out from the transport fan 120 is transported from the attic 16 to the underfloor 17. Note that the communication duct 135 may be constructed in any manner as long as it can transport the conditioned air 210 from the attic 16 to the underfloor 17. For example, as shown in FIG. 12 , the communication duct 135 may be constructed so as to pass through the common space 14, or so as to pass through the wall of the house 500 (in other words, so as not to pass through the common space 14 and the living room 10).

[0065] In this configuration, the conditioned air 210 blown out from the air conditioner 300 is first guided to the transport fan 120 in the attic 16 via the adapter 400. Next, the conditioned air 210 blown out from the transport fan 120 passes through the communication duct 135 and moves from the attic 16 side to the underfloor side 17. Next, the conditioned air 210 is transported to each room 10 via the branch chamber 140 installed on the underfloor 17 side. With this configuration, the rooms 10 can be air-conditioned from the underfloor 17 side. In particular, when the air conditioner 300 is used for heating, the entire room 10 can be heated by taking advantage of the property of warm air rising.

[0066] If the space above the ceiling of the common space 14 is narrow, construction may be carried out as shown in Figure 13. Figure 13 is a schematic diagram showing a configuration different from that shown in Figure 12 in which conditioned air 210 is transported using underfloor space 17.

[0067] 13 , storage top panel 521 is regarded as the ceiling of storage space 520 (common space 14), and storage top compartment 522 is regarded as the attic space 16. In this regard, a ceiling opening 122 is provided in storage top panel 521, air conditioner 300 and adapter 400 are installed in storage bottom compartment 523, and transport fan 120 is installed in storage top compartment 522. In addition, branch chamber 140 is installed under floor 17. Furthermore, one end of communication duct 135 is connected to the air outlet of transport fan 120 installed in storage top compartment 522, and the other end is connected to branch chamber 140 installed under floor 17.

[0068] In this way, when storage space 520 is divided into storage top compartment 522 side and storage bottom compartment 523 side by storage top panel 521, air conditioning system 1000 may be constructed by regarding storage top panel 521 as the ceiling and storage top compartment 522 as attic space 16. In other words, if there is a top panel that spatially divides common space 14 into an upper and lower section, the top panel may be regarded as the ceiling and the upper space may be regarded as attic space 16.

[0069] Even with this configuration, the conditioned air 210 blown out from the transport fan 120 can be transported from the storage top closet 522 side, which is considered to be the attic space 16, to the underfloor space 17 side. Furthermore, even if the space above the ceiling of the common space 14 is narrow, the air conditioning system 1000 can be easily installed.
