Description

[Technical field]

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

[0002] In a house, an air conditioner is installed in a common space facing each room, such as a hallway. The air conditioner performs cooling and heating for the common space, and performs air conditioning so that the common space has a comfortable temperature environment. Furthermore, if a circulator or the like is installed in the common space to mix the air flow and make the temperature more uniform, the result is less unevenness in the air conditioning of each room and a more stable temperature environment (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-148382 A Summary of the Invention [Problem to be solved by the invention]

[0004] Using a common space as an air-conditioned room and a general-purpose air conditioner suppresses the reduction in effective area and the increase in cost compared to installing a dedicated air conditioner in a dedicated air-conditioned room. However, when using a general-purpose air conditioner, it is difficult to supply air blown diagonally downward to each room. Also, when using the common space as an air-conditioned room, the temperature difference between the common space and each room becomes large, reducing comfort.

[0005] The present disclosure has been made in consideration of these circumstances, and has a purpose to provide a technique for suppressing a decrease in air conditioning efficiency even when an air conditioner is installed in a common space. [Means for solving the problem]

[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 rooms that make up the living space, and that draws in air from the common space through an air conditioning inlet 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 the conditioned air from leaking into the common space.

[0007] Another aspect of the present disclosure is an adapter that connects an air conditioner outlet of an air conditioner that is installed in a wall of a common space adjacent to rooms that constitute a living space and that draws in air from the common space through an air conditioner inlet and blows out conditioned air from an air conditioner outlet, to 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. Effect of the Invention

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

[0011] Before specifically describing the embodiment of the present disclosure, an overview of the embodiment will be described. This embodiment relates to an air conditioning system that performs whole-house air conditioning in a house having a common space and a plurality of rooms. The air conditioning system does not use a dedicated air-conditioned room and a dedicated air conditioner in order to suppress a decrease in effective area and an increase in cost. Therefore, the air conditioning system installs a general-purpose air conditioner in a common space such as a corridor, and uses the common space as an air-conditioned room. In addition, a conveying fan is installed in a ceiling opening in the common space, and the conveying fan conveys air in the common space to each room through a duct. In such a situation, as described above, it is difficult to supply air blown diagonally downward to each room, and comfort decreases due to an increase in the temperature difference between the common space and each room. In order to improve these, the air conditioning system is provided with an adapter that covers at least the lower side and the front side of the air conditioner and guides the air blown downward from the air conditioner to the ceiling opening.

[0012] The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps 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, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0013] In the following, the embodiment will be described in the order of (1) overall configuration, (2) adapter and peripheral configuration, and (3) airflow control. (1) Overall structure 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 home in a collective housing complex such as an apartment building, or may be a detached house. The house 500 includes a first room 10a to a fourth room 10d, which are collectively referred to as rooms 10, and a common space 14. The rooms 10 constitute a living space in which people stay for long periods of time. The common space 14 is a space where people spend less time inside than living spaces such as corridors, hallways, and storage spaces such as closets, and is adjacent to the rooms 10. The common space 14 and the rooms 10 are connected to allow ventilation, and air circulates from each room 10 to the common space 14.

[0014] The air conditioning system 1000 includes an outside air inlet 100, an outside air inlet duct 102, a heat exchange type 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 a branch transport duct 142, a first outlet 144a to a seventh outlet 144g collectively referred to as an outlet 144, an air conditioner 300, and an adapter 400. The outside air inlet duct 102, the exhaust duct 106, the heat exchange duct 110, the transport duct 130, and the branch transport duct 142 are tubes that transport air, that is, air paths.

[0015] The outdoor air inlet 100 is installed on a wall surface of the house 500. An outdoor air inlet duct 102 extending from the outdoor air inlet 100 toward the inside 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 wall surface on the south side. A heat exchange duct 110 is also connected to the heat exchange type ventilation fan 104.

[0016] The heat exchange type 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 sucked in from the outside air inlet 100 corresponds to supply air. The heat exchange type ventilation fan 104 also takes in ventilation RA (return air) 202 from a ventilation port (not shown). The ventilation RA 202 is indoor air flowing in from inside the house 500, for example, from inside the room including the living room 10 and the common space 14. The heat exchange type ventilation fan 104 exchanges heat between them. As a result of the heat exchange, the heat exchange type ventilation fan 104 exhausts exhaust air 204 from the exhaust port 108 through the exhaust duct 106. The heat exchange type ventilation fan 104 also exhausts the heat-exchanged supply air 208 (outside air 200) from the heat exchange outlet 112 via the heat exchange duct 110. The heat exchange outlet 112 is an opening provided in the ceiling of the common space 14. That is, the heat exchange type ventilation fan 104 blows out the supply air 208 (heat exchange supply air), which is the outside air 200 that has exchanged heat with the ventilation RA 202 exhausted from the living space, from the heat exchange outlet 112 to the common space 14. Note that if the heat exchange between the ventilation RA 202 and the outside air 200 is sufficient, the heat exchange outlet 112 may be configured to be connected to a transport fan 120 described below. With this configuration, the supply air 208 can be reliably sent to the transport fan 120 without passing through the common space 14.

[0017] The air conditioner 300 is installed on a wall (not shown) of the common space 14, not in a dedicated air-conditioning room. An air conditioner inlet 310 is provided at the top end of the air conditioner 300. A heat exchange outlet 112 is provided vertically above the air conditioner 300, and the supply air 208 blown out from the heat exchange outlet 112 flows in. In addition, the circulating RA 206 flows in from the common space 14, which is inside the house 500, to the air conditioner inlet 310. The circulating RA 206 corresponds to the supply air that has moved inside the house 500, similar to the ventilation RA 202. 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, and the like 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.

[0018] A ceiling opening 122 is provided in the ceiling of the common space 14. A transport fan 120 installed in the ceiling space 16 delivers conditioned air 210 and circulating air RA 206 (hereinafter, these will be referred to as " 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.

[0019] The branch chamber 140 is installed in the ceiling space 16 and is connected to the transport fan 120, and is also connected to the first branch transport duct 142a to the seventh branch transport duct 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 transfer duct 142g is connected to a seventh air outlet 144g provided in the fourth room 10d.

[0020] The conveying fan 120 conveys the conditioned air 210 from the first living room 10a to the fourth living room 10d via the conveying duct 130, the branching chamber 140, the first branch conveying duct 142a to the seventh branch conveying duct 142g, and the first air outlet 144a to the seventh air outlet 144g. Each air outlet 144 is installed on the side wall surface or the ceiling surface of each living room 10, and discharges the conditioned air 210 blown from the conveying fan 120 to each living room 10. Since each living room 10 is connected to the common space 14, the conditioned air 210 blown out from the air outlet 144 is also circulated to the common space 14. A part of the circulating air flows into the air conditioner 300 as the circulating air RA206. In addition, the circulating air RA206 may flow into the conveying fan 120 from the ceiling opening 122. Furthermore, another part of the circulating air is taken into the heat exchange type ventilator 104 as the ventilation air RA202.

[0021] When the conditioned air 210 blown out from the air conditioning outlet 320 of the air conditioner 300 is diffused into the common space 14, the amount of the conditioned air 210 drawn into the conveying fan 120 through the ceiling opening 122 is reduced. This reduces the amount of the conditioned air 210 supplied to each room 10, and the efficiency of the air conditioning is reduced. In order to suppress the reduction in the efficiency of the air conditioning, in this embodiment, as shown in FIG. 2, an adaptor 400 is installed in the common space 14. The adaptor 400 communicates between the air conditioning outlet 320 and the ceiling opening 122, and suppresses leakage of the conditioned air 202 into the common space 14. When leakage of the conditioned air 202 into the common space 14 is suppressed, the reduction in the amount of the conditioned air 210 drawn into the conveying fan 120 through the heat exchange outlet 112 is also suppressed. (2) Adapter and its peripheral configuration FIG. 3 shows the configuration of the air conditioner 300 and the adapter 400. FIG. 9 shows the positional relationship between the air conditioner 300, the adapter 400, and the ceiling opening 122 in a side view, and FIG. 10 shows the positional relationship between the air conditioner 300 and the heat exchange duct 110 in a side view. As described above, the air conditioner 300 is installed on the wall of the common space 14. An air conditioner inlet 310 is arranged at the upper end of the air conditioner 300, and an air conditioner outlet 320 is arranged at the lower end of the air conditioner 300. In addition, 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 conditioner inlet 310 face each other. As shown in FIG. 10, the heat exchange duct 110 may be drawn out from the ceiling so that the heat exchange outlet 112 and the air conditioner inlet 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.

[0022] 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, which are collectively referred to as leak-proof sides 406. The leak-proof bottom surface 402 is disposed so that at least a portion of it covers the air conditioning outlet 320 vertically below the air conditioner 300, and curves and extends upward toward the ceiling. The surface 402 includes not only flat surfaces but also curved surfaces. The leak-proof top surface 404 faces the leak-proof bottom surface 402 and is disposed between the air conditioner 300 and the ceiling of the common space 14.

[0023] The first leakage prevention side surface 406a and the second leakage prevention side surface 406b are connected to the leakage prevention bottom surface 402 and the leakage prevention top surface 404, and are arranged opposite each other. The first leakage prevention side surface 406a has a first cutout portion 407a in which the upper portion on the air conditioner 300 side is cut out, and the second leakage prevention side surface 406b has a second cutout portion 407b in which the upper portion on the air conditioner 300 side is cut out. The first cutout portion 407a and the second cutout portion 407b are collectively referred to as the cutout portion 407. The cutout portion 407 fixes the adapter 400 in a state in which the air conditioner intake port 310 is exposed to the common space 14.

[0024] 3 and 9, the space surrounded by 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 is the ventilation space 408, which is spatially independent from the common space 14. The downstream 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 are connected to the ceiling of the common space 14 while surrounding the ceiling opening 122.

[0025] Further, the upstream ends of the leakage prevention bottom surface 402, the leakage prevention top surface 404, the first leakage prevention side surface 406a, and the second leakage prevention side surface 406b surround and cover the air conditioning outlet 320. In other words, the upstream end of the leakage prevention bottom surface 402 is located below the air conditioning outlet 320, and the upstream end of the leakage prevention top surface 404 is located above the air conditioning outlet 320. Furthermore, when the air conditioner 300 is viewed from the front, the upstream end of the first leakage prevention side surface 406a is located to the left of the air conditioning outlet 320, and the upstream end of the second leakage prevention 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 to the ceiling opening 122 through the air blowing space 408. In other words, the conditioned air 210 can be prevented from diffusing into the common space 14. The upstream end of the leakage prevention top surface 404 may be configured to abut against the air conditioner 300 above the air conditioning outlet 320. Such a configuration can further prevent the conditioned air 210 guided to the ceiling opening 122 from leaking from the ventilation space 408 to the common space 14. The upstream ends of the leakage prevention bottom surface 402 and the first and second leakage prevention sides 406a and 406b may also abut against the air conditioner 300.

[0026] The supply air 208 blown out from the heat exchanger outlet 112 is sucked into the air conditioner intake 310 of the air conditioner 300. In addition, the circulating air RA 206 in the common space 14 passes through the first notch 407a of the first leakage prevention side surface 406a or the second notch 407b of the second leakage prevention side surface 406b, and is sucked into the air conditioner intake 310 of the air conditioner 300. In addition, the conditioned air 210 blown out from the air conditioner outlet 320 of the air conditioner 300 is mainly guided to the ceiling opening 122 by passing through the blowing space 408.

[0027] The leak prevention 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 is acceptable as long as it is possible to guide the conditioned air 210 to the ceiling opening 122. For example, the leak prevention bottom surface 402 may have a bent shape rather than a curved shape. The leak prevention 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.

[0028] 4(a)-(d) show the configuration of the air conditioner 300, the transport fan 120, and the branch chamber 140. FIG. 4(a) shows the configuration when the air conditioner 300, the transport fan 120, and the branch chamber 140 are viewed obliquely from above, and FIG. 4(b) shows the cross-sectional configuration when the air conditioner 300, the transport fan 120, and the branch chamber 140 are viewed obliquely from above. FIG. 4(c) shows the configuration when the air conditioner 300, the transport fan 120, and the branch chamber 140 are viewed directly from the side, and FIG. 1D) 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.

[0029] 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 a screw or the like. Regarding the downstream end fixing part 410, priority is given to fixing it to the ceiling to prevent air from directly entering the ceiling opening 122 from the common space 14, but it may be detachable.

[0030] 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.

[0031] The upstream side of the leakage prevention top surface 404, that is, the end on the air conditioner 300 side, is called the top surface upstream end 416, and an inflow opening 414 is formed between the top surface upstream end 416 and the air conditioner 300. The inflow opening 414 is an opening for allowing the circulation RA206 of the common space 14 to flow into the air blowing space 408. If the air volume of the conveying fan 120 is larger than the air volume of the air conditioner 300, the load on the air conditioner 300 increases. The inflow opening 414 is provided to reduce the load on the air conditioner 300. In addition, the inflow opening 414 is positioned below the top surface upstream end 416 and the air conditioner intake port 310 in order to avoid the occurrence of a short circuit. Furthermore, the leakage prevention top surface 404 may be provided with an inflow opening adjustment unit that adjusts the size of the inflow opening 414. The inflow opening adjustment unit is, for example, a shutter that slides along the leakage prevention 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 section, and the top surface upstream end 416 may be brought into contact with the air conditioner 300 .

[0032] An openable / closable opening / closing panel section 420 is provided on the leak-preventing bottom surface 402. By opening the opening / closing panel section 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 in communication with the air conditioner 300. For example, it is possible to maintain the air conditioner 300 with a vacuum cleaner through the maintenance opening 418.

[0033] 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 406a, and the second filter 422b is provided on approximately the same plane as the second leakage prevention side 406b. The first filter 422a and the second filter 422b are collectively referred to as the filter 422. The filter 422 purifies the circulating air RA206 sucked from the common space 14 to the air conditioner intake 310 on the upstream side of the air conditioner intake 310. This configuration makes it possible to keep the inside of the air conditioner 300 clean, and to reduce the frequency of maintenance of the air conditioner 300 performed through the maintenance opening 418.

[0034] 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 ventilation gap 424. The ventilation gap 424 is a gap for ventilating the circulation air RA206 in the common space 14 that has passed through the filter 422 to the air conditioning intake port 310. Such ventilation gap 424 ensures the effective area of ​​the filter 422. (3) Airflow 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 transport 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 transport 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, one controller that controls the air conditioner 300 and the transport fan 120 is illustrated as an example. 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 transport fan 120 are provided separately. (3-1) First configuration In the first configuration, the air conditioning air volume of the air conditioner 300 is adjusted in accordance with the fan air volume of the transport fan 120. Figures 5(a)-(b) show a first configuration of the controller 460 in the air conditioning system 1000. As shown in Figure 5(a), the air conditioning system 1000 includes a transport fan 120, an air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 also includes a room temperature acquisition unit 462, a fan air volume control unit 466, a fan air volume acquisition unit 468, and an air conditioning air volume control unit 472.

[0035] The temperature sensor 450 is installed in the living room 10 and detects the temperature of the living room 10 (hereinafter referred to as the "room temperature"). The temperature sensor 450 has a communication function such as wireless communication, and transmits the detected 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.

[0036] The controller 460 is installed in the house 500 of FIG. 1 and FIG. 2. The controller 460 controls the entire air conditioning system 1000. The controller 460 is communicatively connected to the transport fan 120, the air conditioner 300, and the temperature sensor 450 by wireless communication. At least some of these may be communicatively connected by 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 air volume acquisition unit 468 acquires the fan air volume by receiving the fan air volume setting from the transport fan 120. The fan air volume may be acquired from the transport fan 120 or from the fan air volume control unit 466.

[0037] The fan airflow control unit 466 receives the room temperature from the room temperature acquisition unit 462. FIG. 5(b) is an example of a table held in the fan airflow control unit 466. As shown in the figure, the room temperature and the fan airflow are associated with each other. The fan airflow control unit 466 determines the fan airflow by referring to the table based on the acquired room temperature. Return to FIG. 5(a). At that time, if the determined fan airflow is smaller than the air-conditioning airflow, the air-conditioning airflow control unit 472 sets the air-conditioning airflow to be equal to or less than the fan airflow. The air-conditioning airflow control unit 472 adjusts the air-conditioning airflow of the air conditioner 300 by transmitting the determined air-conditioning airflow to the air conditioner 300. Here, "setting the air-conditioning airflow to be equal to or less than the fan airflow" also includes making the air-conditioning airflow and the fan airflow equal. By making the fan airflow and the air-conditioning airflow acquired by the fan airflow acquisition unit 468 equal, the air-conditioned air 210 can be conveyed to each room while suppressing the load on the air conditioner 300. (3-2) Second configuration In the second configuration, the fan air volume of the transport fan 120 is adjusted according to the air conditioning air volume of the air conditioner 300. Fig. 6(a)-(b) shows a second configuration of the controller 460 in the air conditioning system 1000. As shown in Fig. 6(a), 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, an air conditioning temperature control unit 470, an air conditioning air volume control unit 472, an air conditioning air volume acquisition unit 464, and a fan air volume 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 air volume of the air conditioner 300 to the controller 460.

[0038] 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 air volume acquisition unit 464 acquires the air conditioning air volume by receiving the air conditioning air volume setting from the air conditioner 300. The air conditioning air volume may be acquired from the air conditioner 300 or may be acquired from the air conditioning air volume 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 "air conditioning temperature") based on the room temperature and the set temperature. A known technique may be used to determine the air conditioning temperature, but 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 .

[0039] The air conditioning airflow control unit 472 receives the room temperature from the room temperature acquisition unit 462. FIG. 6(b) is an example of a table stored in the air conditioning airflow control unit 472. As shown in the figure, the room temperature and the air conditioning airflow are associated with each other. The air conditioning airflow control unit 472 determines the air conditioning airflow by referring to the table based on the acquired room temperature. Return to FIG. 6(a). At that time, if the determined air conditioning airflow is greater than the fan airflow, the fan airflow control unit 466 makes the fan airflow equal to or greater than the air conditioning airflow. The fan airflow control unit 466 adjusts the fan airflow of the transport fan 120 by transmitting the determined fan airflow to the transport fan 120. Here, "making the fan airflow equal to or greater than the air conditioning airflow" also includes making the fan airflow and the air conditioning airflow equal. By making the air conditioning airflow and the fan airflow acquired by the air conditioning airflow acquisition unit 464 equal to each other, the air conditioning air 210 can be transported to each room while suppressing the load on the air conditioner 300. (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. Fig. 7(a)-(b) shows a third configuration of the controller 460 in the air conditioning system 1000. As shown in Fig. 7(a), 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.

[0040] 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. 7(b) is an example of a table held in the air volume control unit 474. As shown in the figure, the air conditioning air volume and the fan air volume are associated with the room temperature. 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 refers to the table based on the acquired room temperature to determine the air conditioning air volume and the fan air volume. The air volume control unit 474 transmits the determined air conditioning air volume to the air conditioner 300, and adjusts the air conditioning air volume of the air conditioner 300 and the fan air volume of the transport fan 120 by transmitting the determined fan air volume to the transport fan 120. (3-4) Fourth configuration In the fourth configuration, the fan air volume of the transport fan 120 is adjusted in accordance with the heat exchanger supply air volume of the heat exchanger type ventilation fan 104. Figures 8(a)-(b) show a fourth configuration of the controller 460 in the air conditioning system 1000. As shown in Figures 8(a) and 8(b), the air conditioning system 1000 includes the heat exchanger type ventilation fan 104, the transport fan 120, and a controller 460. The controller 460 also includes a heat exchanger supply air volume storage unit 478, a heat exchanger supply air volume acquisition unit 476, and a fan air volume control unit 466a.

[0041] The heat exchanger supply air volume storage unit 478 stores the setting of the heat exchanger supply air volume generated by the heat exchanger type ventilation fan 104. The heat exchanger supply air volume storage unit 478 stores the setting of the heat exchanger type ventilation fan 104 that was set according to the size of the house 500 at the time of construction, for example.

[0042] The heat exchanger supply airflow rate acquisition unit 476 acquires the heat exchanger supply airflow rate by receiving the heat exchanger supply airflow rate setting from the heat exchanger type ventilation fan 104. Note that the heat exchanger supply airflow rate setting stored in the heat exchanger supply airflow rate storage unit 478 may be received as shown in FIG. 8(b).

[0043] The fan airflow control unit 466a controls the transport fan 120 based on the heat exchanger supply airflow received from the heat exchanger supply airflow acquisition unit 476. When the heat exchanger supply airflow is greater than the fan airflow, the fan airflow control unit 466a sets the fan airflow to be equal to or greater than the heat exchanger supply airflow. The fan airflow control unit 466a adjusts the fan airflow of the transport fan 120 by transmitting the determined fan airflow to the transport fan 120.

[0044] The fourth configuration is a method for mainly controlling the lower limit of the fan air volume, and is effective as a means for ensuring the fan air volume required to supply all of the supply air 208 to each room even when the air conditioner 300 is stopped and the air conditioning air volume becomes zero during the intermediate seasons of spring and fall. Therefore, by using it in combination with each of the (3-1) first configuration, (3-2) second configuration, and (3-3) third configuration, it becomes possible to control the air volume of each device to perform necessary and sufficient air conditioning and ventilation throughout the year.

[0045] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function 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 one chip or may be provided on multiple chips. The multiple chips may be integrated into one 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 disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0046] According to this embodiment, the adapter 400 communicates the air conditioning outlet 320 of the air conditioner 300 with the ceiling opening 122 provided in the ceiling of the common space 14, and suppresses leakage of the conditioned air 210 into the common space 14, so that a decrease in air conditioning efficiency can be suppressed even when the air conditioner 300 is installed in the common space 14. In addition, since the adapter 400 is used, even when a general-purpose air conditioner 300 is used, air can be blown out obliquely downward to each room 10. In addition, since the adapter 400 is used, even when the common space 14 is used as an air-conditioned room, an increase in the temperature difference between the common space 14 and each room 10 can be suppressed. In addition, since an increase in the temperature difference between the common space 14 and each room 10 is suppressed, a decrease in comfort can be suppressed.

[0047] Furthermore, since 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, since the adapter 400 has an air blowing space 408 surrounded by the leakage prevention bottom surface 402, the leakage prevention top surface 404, and the two leakage prevention side surfaces 406, it is possible to prevent the conditioned air 210 from leaking into the common space 14. Furthermore, since the downstream end fixing portion 410 fixes the downstream end of the adapter 400 to the ceiling, it is possible to prevent the conditioned air 210 from leaking into the common space 14. Furthermore, since 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, it is possible to prevent the conditioned air 210 from leaking into the common space 14.

[0048] In addition, since the adapter 400 is fixed in a state where the air conditioner intake port 310 is exposed to the common space 14, the circulating air RA 206 in the common space 14 can be sucked into the air conditioner intake port 310. In addition, since the inflow opening 414 is provided on the leakage prevention top surface 404, the circulating RA206 is allowed to flow into the air blowing space 408, thereby suppressing an increase in the load on the air conditioner 300. Furthermore, since the size of the inflow opening 414 is adjusted by the inflow opening adjustment unit, the amount of circulating RA206 allowed to flow into the air blowing space 408 can be adjusted. Furthermore, since the air conditioner intake port 310 is provided at the upper end of the air conditioner 300, and the inflow opening 414 is located at the upstream end of the leakage prevention top surface 404 and below the air conditioner intake port 310, the occurrence of a short circuit can be avoided.

[0049] In addition, the leak prevention bottom surface 402 is provided with a maintenance opening 418 and an opening / closing panel portion 420, so that maintenance of the air conditioner 300 can be performed with the adapter 400 attached to the air conditioner 300. In addition, the filter 422 is provided, so that the circulation RA 206 can be purified. In addition, a ventilation gap 424 is provided between the filter 422 and the air conditioner 300, so that the effective area of ​​the filter 422 can be secured. In addition, the heat exchange type ventilation fan 104 blows the supply air 208 from the heat exchange outlet 112 to the common space 14, so that the difference between the temperature of the common space 14 and the temperature of the supply air 208 can be reduced. In addition, the heat exchange outlet 112 is provided vertically above the air conditioner 300, so that the supply air 208 can be efficiently sucked into the conditioned air 210.

[0050] Moreover, since the fan airflow rate is adjusted based on the room temperature, a fan airflow rate suitable for the room temperature can be used. Moreover, since the fan airflow rate is set to be equal to or greater than the conditioned airflow rate, an increase in the load on the air conditioner 300 can be suppressed. Moreover, since the airflow rate is controlled based on the room temperature, a conditioned airflow rate suitable for the room temperature can be used. Moreover, since the conditioned 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. Moreover, since the fan airflow rate and the conditioned airflow rate are controlled so that the fan airflow rate is equal to or greater than the conditioned airflow rate, a fan airflow rate and conditioned airflow rate suitable for the environment can be used while suppressing an increase in the load on the air conditioner 300.

[0051] In the embodiment of the present disclosure, as an example, a case where the air conditioner 300 is installed in a hallway, which is a common space 14, as shown in Fig. 1 has been described, but the installation location of the air conditioner 300 is not limited to the hallway. The air conditioner 300 may be installed anywhere in the common space 14 adjacent to the rooms 10 that constitute the living space. For example, as shown in Fig. 11, the air conditioner 300 and the adapter 400 may be installed above a storage space 520 adjacent to a certain room 10e. Here, Fig. 11 is a schematic diagram showing a configuration when the air conditioner 300 and the branch chamber 400 are installed in the storage space 520.

[0052] 11, the corridor 510 is common space 14 and adjacent to each room including the living room 10e in a manner that allows ventilation. Also, the storage space 520 is common space 14 and adjacent to a certain living room 10e in a manner that allows ventilation. The corridor 510 and the storage space 520 are adjacent to each other with a wall portion 534 that cannot be opened or closed in between.

[0053] A certain living room 10e and the storage space 520 are adjacent to each other across a door portion 532. Here, the door portion 532 can be opened and closed, and communicates the common space 14 and the living room 10 to allow ventilation.

[0054] Storage space 520 is divided into an upper section and a lower section by storage top board 521 that is provided parallel to the floor surface. The space above storage top board 521 is storage closet 522, and the space below storage top board 521 is storage bottom board 523. In Fig. 12, air conditioner 300 and adapter 400 are installed in storage top board 522, which is the upper part of storage space 520.

[0055] In such a configuration, air from each room first flows into a certain room 10e via the corridor 510. The air from each room is then ventilated into the storage space 520 via the certain room 10e, and can be conditioned by the air conditioner 300. The conditioned air is guided to the transport fan 120 in the attic 16 via the adapter 400, and is transported to each 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 such a configuration, the air from each room that has been ventilated into the corridor 510 can be taken directly from the corridor 510 to the storage space 520. It can be inserted to provide air conditioning.

[0056] In the embodiment of the present disclosure, the case where the conditioned air 210 is transported from the ceiling space 16 side to the room 10 as shown in FIG. 2 has been described as an example, but the present invention is not limited to this. For example, as shown in FIG. 12, a communication duct 135 that communicates the ceiling space 16 and the underfloor space 17 may be installed to transport the conditioned air 210 from the underfloor space 17 side to the room 10. Here, FIG. 12 is a schematic diagram showing a configuration in which the conditioned air 210 is transported using the underfloor space 17. In FIG. 12, the transport fan 120 is located in the ceiling space 16, and the branch chamber 140 is located under the floor space 17. In FIG. 12, the air conditioning system 1000 further includes a communication duct 135 as an air passage.

[0057] The communication duct 135 is an air passage that communicates between the attic space 16, which is a space located above the ceiling of the common space 14, and the underfloor space 17, which is a space located below the floor surface 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 space 16, and the other end is connected to the branch chamber 140 installed in the underfloor space 17. With this configuration, the conditioned air 210 blown out from the transport fan 120 is transported from the attic space 16 side to the underfloor space 17 side. The communication duct 135 may be constructed in any manner as long as it can transport the conditioned air 210 from the attic space 16 side to the underfloor space 17 side. For example, as shown in FIG. 12, the communication duct 135 may be constructed so as to pass through the common space 14, or may be constructed so as to pass through the wall of the house 500 (in other words, not to pass through the common space 14 and the living room 10).

[0058] In such a configuration, first, the conditioned air 210 blown out from the air conditioner 300 is 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 moves from the attic 16 side to the underfloor side 17 through the communication duct 135. Next, the conditioned air 210 is transported to each room 10 via the branch chamber 140 installed on the underfloor 17 side. With such a configuration, the room 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 tendency of warm air to rise.

[0059] If the space above the ceiling of the common space 14 is narrow, construction may be performed as shown in Fig. 13. Fig. 13 is a schematic diagram showing a case in which conditioned air 210 is transported using underfloor 17 in a configuration different from that shown in Fig. 12.

[0060] 13, storage top board 521 is regarded as the ceiling of storage space 520 (common space 14), and storage top board 522 is regarded as the ceiling space 16. When regarded in this way, a ceiling opening 122 is provided in storage top board 521, air conditioner 300 and adapter 400 are installed in storage bottom board 523, and transport fan 120 is installed in storage top board 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 board 522, and the other end is connected to branch chamber 140 installed under floor 17.

[0061] 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 the attic space 16. In other words, if there is a top panel that spatially divides common space 14 into an upper and lower portion, the top panel may be regarded as the ceiling and the upper space as the attic space 16.

[0062] 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 regarded as the attic space 16, to the underfloor space 17 side. Also, even if the space above the ceiling of the common space 14 is narrow, the air conditioning system 1000 can be easily installed.
