Description

Technical Field

[0001] The present disclosure relates to air conditioning technology, and particularly to an air conditioning system and an adapter for controlling the air conditioning of a plurality of living rooms.

Background Art

[0002] An air conditioner is installed in a common space facing each living room in a house, for example, a corridor. The air conditioner performs cooling and heating on the common space and executes air conditioning so that the common space has a comfortable temperature environment. Further, if a circulator or the like is installed in the common space to stir the air flow so that the temperature becomes more uniform, as a result, the air conditioning of each living room also becomes less uneven and the temperature environment becomes stable (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] When using a common space as an air-conditioned room and using a general-purpose air conditioner, compared with the case of installing a dedicated air conditioner in a dedicated air-conditioned room, a reduction in effective area and an increase in cost are suppressed. However, when using a general-purpose air conditioner, it is difficult to supply obliquely downward blown air to each living room. Further, when using a common space as an air-conditioned room, the temperature difference between the common space and each living room becomes large, and comfort decreases.

[0005] The present disclosure has been made in view of such a situation, and an object thereof is 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 Problems

[0006] To solve the above problems, an air conditioning system in one aspect of the present disclosure includes an air conditioner installed in an indoor wall that draws in indoor air from an air conditioning intake and blows conditioned air from an air conditioning outlet, and an adapter that connects the air conditioning outlet to a ceiling opening provided in the indoor ceiling and suppresses leakage of conditioned air into the indoor space. The adapter includes a leakage-preventing bottom surface that curves from below the air conditioning outlet, passes across the front of the air conditioner, and extends upward toward the ceiling.

[0007] Another aspect of the present disclosure is an adapter. This adapter connects the air conditioner outlet of an air conditioner installed in an indoor wall, which draws in indoor air from an air conditioner intake and blows conditioned air from an air conditioner outlet, with a ceiling opening provided in the indoor ceiling, and includes a leak-proof bottom surface that curves from below the air conditioner outlet, passes in front of the air conditioner, and extends upward toward the ceiling.

[0008] Furthermore, any combination of the above components, as well as any conversion of the expressions of this disclosure between methods, apparatus, systems, recording media, computer programs, etc., are also valid as aspects of this disclosure. [Effects of the Invention]

[0009] According to this disclosure, even when air conditioners are installed indoors, the decrease in air conditioning efficiency can be suppressed. [Brief explanation of the drawing]

[0011] Before specifically describing the embodiments of this disclosure, an overview of the embodiments will be provided. This embodiment relates to an air conditioning system that provides whole-house air conditioning in a house having a common space and multiple living rooms. In order to suppress the reduction in effective area and the increase in cost, the air conditioning system does not use a dedicated air conditioning room or dedicated air conditioner. 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 conditioning room. In addition, a transport fan is installed in the ceiling opening of the common space, and the transport fan transports the air from the common space to each living room via ducts. In this situation, as described above, it is difficult to supply diagonally downward-blowing air to each living room, and the comfort level decreases due to the widening temperature difference between the common space and each living room. To improve these issues, the air conditioning system is equipped with an adapter that covers at least the bottom and front of the air conditioner and guides the downward-blowing air from the air conditioner to the ceiling opening.

[0012] The embodiments described below all show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components shown in the following embodiments, as well as the steps (processes) and the order of the steps, etc. are just examples and not intended to limit the present disclosure. Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the most basic concept of the present disclosure are described as arbitrary components. Also, in each figure, the same reference numerals are given to substantially the same configurations, and duplicate descriptions are omitted or simplified.

[0013] Hereinafter, the embodiments will be described in the order of (1) overall configuration, (2) configuration of the adapter and its surroundings, and (3) air volume control. (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 residence of a single household in an apartment building or the like, or a detached house. The house 500 includes a first bedroom 10a to a fourth bedroom 10d collectively referred to as a living room 10, and a common space 14. The living room 10 constitutes a living space where people stay inside for a long time. The common space 14 is a space where people stay inside for a shorter time compared to living spaces such as passages like corridors and entrances, and storage spaces like closets, and is adjacent to the living room 10. Also, the common space 14 and the living room 10 are communicatively connected so that air can circulate from each living room 10 to the common space 14.

[0014] The air conditioning system 1000 includes an outdoor air inlet 100, an outdoor air intake 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 conveying fan 120, a conveying duct 130, a branch chamber 140, first to seventh branch conveying ducts 142a to 142g collectively referred to as the branch conveying duct 142, first to seventh outlets 144a to 144g collectively referred to as the outlet 144, an air conditioner 300, and an adapter 400. The outdoor air intake duct 102, the exhaust duct 106, the heat exchange duct 110, the conveying duct 130, and the branch conveying duct 142 are pipes for transporting air, that is, air ducts.

[0015] The outdoor air inlet 100 is installed on the wall surface of the house 500. The outdoor air intake duct 102 extending from the outdoor air inlet 100 toward the inside of the house 500 is connected to the heat exchange ventilation fan 104. The heat exchange ventilation fan 104 is arranged, for example, in the ceiling space 16 of the common space 14. The exhaust duct 106 is also connected to the heat exchange ventilation fan 104. The exhaust duct 106 extends toward the wall surface of the house 500 and is connected to the exhaust port 108 installed on the south wall surface. The heat exchange duct 110 is also connected to the heat exchange ventilation fan 104.

[0016] The heat exchange ventilator 104 takes in outside air 200 from the outside air inlet 100 through the outside air intake duct 102. The outside air 200 drawn in from the outside air inlet 100 corresponds to the supply air. The heat exchange ventilator 104 also takes in ventilation RA (Return Air) 202 from a ventilation opening (not shown). The ventilation RA 202 is indoor air flowing in from inside the house 500, for example, from the rooms including the living room 10 and the common space 14. The heat exchange ventilator 104 performs heat exchange between these. As a result of the heat exchange, the heat exchange ventilator 104 discharges exhaust 204 from the exhaust port 108 through the exhaust duct 106. The heat exchange ventilator 104 also discharges 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 in the ceiling of the common space 14. In other words, the heat exchange ventilation fan 104 blows out the supply air 208 (heat exchange supply air), which is outside air 200 that has exchanged heat with the ventilation RA202 exhausted from the living space, into the common space 14 from the heat exchange outlet 112. If the heat exchange between the ventilation RA202 and the outside air 200 is sufficient, the heat exchange outlet 112 may be connected to the transport fan 120 described later. With such a configuration, the supply air 208 can be reliably sent to the transport fan 120 because it does not pass through the common space 14.

[0017] The air conditioner 300 is installed not in a dedicated air conditioning room, but on the wall (not shown) of the common space 14. An air conditioning intake port 310 is provided at the top 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 into it. In addition, circulating RA206 flows into the air conditioning intake port 310 from the common space 14, which is the interior of the house 500. The circulating RA206, like the ventilation RA202, corresponds to the supply air that has moved within the house 500. The air conditioner 300 is a general-purpose air conditioner and performs air conditioning on the circulating RA206 and the supply air 208. The air conditioner 300 controls the temperature and humidity of the circulating RA206 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 lower 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 intake 310 and blows out 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 draws in conditioned air 210 and circulating RA206 (hereinafter sometimes referred to as "conditioned air 210") from the ceiling opening 122. The transport fan 120 is connected to a branching chamber 140 via a transport duct 130 and transports the conditioned air 210 to the branching chamber 140.

[0019] The branching chamber 140 is installed in the ceiling space 16 and is connected to the transport fan 120, as well as to the first branching transport duct 142a through the seventh branching transport duct 142g. The first branching transport duct 142a is connected to the first outlet 144a installed in the first living room 10a, and the second branching transport duct 142b is connected to the second outlet 144b installed in the second living room 10b. The third branching transport duct 142c is connected to the third outlet 144c installed in the third living room 10c, and the fourth branching transport duct 142d is connected to the fourth outlet 144d installed in the fourth living room 10d. The fifth branching transport duct 142e is connected to the fifth outlet 144e installed in the first living room 10a, and the sixth branching transport duct 142f is connected to the sixth outlet 144f installed in the second living room 10b. The seventh branch transport duct 142g is connected to the seventh air outlet 144g, which is installed in the fourth living room 10d.

[0020] The transport fan 120 transports conditioned air 210 from the first room 10a to the fourth room 10d via the transport duct 130, branch chamber 140, first branch transport duct 142a to the seventh branch transport duct 142g, and first outlet 144a to the seventh outlet 144g. Each outlet 144 is installed on the side wall or ceiling surface 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 outlets 144 also circulates into the common space 14. A portion of the circulating air flows into the air conditioner 300 as circulating RA206. In addition, circulating RA206 may flow into the transport fan 120 from the ceiling opening 122. Furthermore, another portion of the circulating air is taken in by the heat exchange ventilation fan 104 as ventilation RA202.

[0021] When 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 transport fan 120 via the ceiling opening 122 decreases. As a result, the amount of conditioned air 210 supplied to each room 10 also decreases, reducing the efficiency of the air conditioning. To suppress the decrease in air conditioning efficiency, in this embodiment, as shown in Figure 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, suppressing the leakage of conditioned air 202 into the common space 14. When the leakage of conditioned air 202 into the common space 14 is suppressed, the decrease in the amount of conditioned air 210 drawn into the transport fan 120 via the heat exchanger outlet 112 is also suppressed. (2) Adapter and its surrounding configuration Figure 3 shows the configuration of the air conditioner 300 and the adapter 400. Figure 9 shows the positional relationship between the air conditioner 300, the adapter 400 and the ceiling opening 122 in a side view, and Figure 10 shows the positional relationship between the air conditioner 300 and the heat exchanger 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 conditioning intake port 310 is located at the upper end of the air conditioner 300, and an air conditioning outlet port 320 is located at the lower end of the air conditioner 300. In addition, a heat exchanger outlet port 112 and a ceiling opening 122 are provided on the ceiling of the common space 14. For example, the heat exchanger outlet port 112 and the air conditioning intake port 310 face each other. Alternatively, as shown in Figure 10, the heat exchanger duct 110 may be routed from the ceiling so that the heat exchanger outlet port 112 and the air conditioning intake port 310 are located on approximately the same plane. In other words, the tip of the heat exchange duct 110 may be brought into contact with the upper end of the air conditioner 300. With this configuration, the diffusion of the supply air 208 (heat exchange supply air) into the common space 14 is suppressed, and the entire amount of supply air 208 can be conditioned by the air conditioner 300 before being supplied 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, collectively referred to as the leak-proof side surface 406. The bottom surface 402 is positioned so as to cover the air conditioning outlet 320 vertically below the air conditioner 300, at least in part, and extends upward toward the ceiling in a curved manner. Thus, the leakage prevention bottom surface 402 includes not only a flat surface but also a curved surface. The leakage prevention top surface 404 is positioned opposite the leakage prevention bottom surface 402, between the air conditioner 300 and the ceiling of the common space 14.

[0023] The first leak-preventing side surface 406a and the second leak-preventing side surface 406b are connected to the leak-preventing bottom surface 402 and the leak-preventing top surface 404, and are arranged facing each other. The first leak-preventing side surface 406a has a first notch 407a in which the upper part on the air conditioner 300 side is missing, and the second leak-preventing side surface 406b has a second notch 407b in which the upper part on the air conditioner 300 side is missing. The first notch 407a and the second notch 407b are collectively referred to as the notch 407. The notch 407 fixes the adapter 400 with the air conditioner intake port 310 exposed to the common space 14.

[0024] As shown in Figures 3 and 9, the space enclosed by the leak-proof bottom surface 402, the leak-proof top surface 404, the first leak-proof side surface 406a, and the second leak-proof side surface 406b is the ventilation space 408, and the ventilation space 408 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 406a, and the second leak-proof side surface 406b are connected to the ceiling of the common space 14 while surrounding the ceiling opening 122.

[0025] Furthermore, the upstream ends of the leak-proof bottom surface 402, the leak-proof top surface 404, the first leak-proof side surface 406a, and the second leak-proof side surface 406b surround and cover the air conditioning outlet 320. In other words, the upstream end of the leak-proof bottom surface 402 is located below the air conditioning outlet 320, and the upstream end of the leak-proof top surface 404 is located above the air conditioning outlet 320. Also, when viewing the air conditioner 300 from the front, the upstream end of the first leak-proof side surface 406a is located to the left of the air conditioning outlet 320, and the upstream end of the second leak-proof 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 ventilation space 408 to the ceiling opening 122. In other words, diffusion of the conditioned air 210 into the common space 14 can be suppressed. Furthermore, the upstream end of the leakage prevention top surface 404 may be configured to abut the air conditioner 300 above the air conditioning outlet 320. With such a configuration, leakage of the conditioned air 210 guided to the ceiling opening 122 from the ventilation space 408 into the common space 14 can be further suppressed. In addition, the upstream ends of the leakage prevention bottom surface 402, the first leakage prevention side surface 406a, and the second leakage prevention side surface 406b may also abut the air conditioner 300.

[0026] The supply air 208 blown out from the heat exchanger outlet 112 is drawn into the air conditioning intake port 310 of the air conditioner 300. In addition, the circulating RA206 in the common space 14 is drawn into the air conditioning intake port 310 of the air conditioner 300 by passing 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. Furthermore, the conditioned air 210 blown out from the air conditioning outlet 320 of the air conditioner 300 is mainly guided to the ceiling opening 122 by passing through the ventilation space 408.

[0027] The leak-preventing bottom surface 402 has a streamlined design that directs the conditioned air 210 blown out from the air conditioning outlet 320 towards the ceiling opening 122, in order to quickly draw the conditioned air 210 blown out from the air conditioning outlet 320 into the ceiling opening 122. However, any shape other than a streamlined design is acceptable as long as it is possible to guide the conditioned air 210 into the ceiling opening 122; for example, the leak-preventing bottom surface 402 may be bent instead of curved. The leak-preventing top surface 404 can also be described as an airflow separator plate that prevents the conditioned air 210 blown out from the air conditioning outlet 320 from going to the air conditioning intake 310.

[0028] Figures 4(a)-(d) show the configuration of the air conditioner 300, conveyor fan 120, and branching chamber 140. Figure 4(a) shows the configuration of the air conditioner 300, conveyor fan 120, and branching chamber 140 when viewed from diagonally above, and Figure 4(b) shows the configuration of the air conditioner 300, conveyor fan 120, branching Figure 4(c) shows the cross-sectional configuration of the chamber 140 when viewed from an oblique angle above. Figure 4(d) shows the configuration of the air conditioner 300, transport fan 120, and branching chamber 140 when viewed from the side, and Figure 4(d) shows the cross-sectional configuration of the air conditioner 300, transport fan 120, and branching chamber 140 when viewed from above. The transport duct 130, which was previously omitted, is connected to the transport fan 120 and the branching chamber 140, and guides the conditioned air 210 from the transport fan 120 to the branching 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 bracket and is fixed to the downstream end of the adapter 400 and the ceiling using screws or the like. Regarding the downstream end fixing part 410, fixing to the ceiling is prioritized to prevent air from directly entering the ceiling opening 122 from the common space 14, but it may also 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 bracket 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 end of the leakage prevention top surface 404, that is, the end on the side of the air conditioner 300, 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 RA206 of the common space 14 to flow into the ventilation space 408. If the airflow of the conveying fan 120 is greater than the airflow 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. In addition, the inlet opening 414 is located below the top surface upstream end 416 and the air conditioner intake port 310 in order to avoid the occurrence of short circuits. Furthermore, the leakage prevention top surface 404 may be provided with an inlet opening adjustment section to adjust the size of the inlet opening 414. The inlet opening adjustment section is, for example, a shutter that slides along the leakage prevention top surface 404. If the load on the air conditioner 300 is small, the inlet opening 414 may be completely closed by the inlet opening adjustment unit, and the top upstream end 416 may be brought into contact with the air conditioner 300.

[0032] The leak-proof bottom surface 402 is provided with an openable / closable panel section 420. By opening the openable / closable panel section 420, a maintenance opening 418 in the leak-proof bottom surface 402 is exposed. The maintenance opening 418 is an opening for maintaining the air conditioner 300 while the adapter 400 is connected to the air conditioner 300. For example, it is possible to clean the air conditioner 300 with a vacuum cleaner through the maintenance opening 418.

[0033] A first filter 422a is installed in the first notch 407a, and a second filter 422b is installed in the second notch 407b. Therefore, the first filter 422a is provided on approximately the same plane as the first leak-preventing side surface 406a, and the second filter 422b is provided on approximately the same plane as the second leak-preventing side surface 406b. The first filter 422a and the second filter 422b are collectively referred to as filter 422. Filter 422 purifies the circulating RA206 that is drawn in from the common space 14 to the air conditioning intake port 310 on the upstream side of the air conditioning intake port 310. This configuration makes it possible to keep the inside of the air conditioner 300 clean and reduces the frequency of maintenance of the air conditioner 300 performed through the maintenance opening 418.

[0034] A first ventilation gap 424a is positioned between the first filter 422a and the side of the air conditioner 300, and a second ventilation gap 424b is positioned between the second filter 422b and the side 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 that allows the circulating RA206 of the common space 14, which has passed through the filter 422, to be ventilated to the air conditioner intake port 310. Through such a ventilation gap 424, the filter 422 Effective area is secured. (3) Air volume control In the following, the control of the airflow of the air conditioner 300 (hereinafter referred to as "air conditioning airflow") and the airflow of the transport fan 120 (hereinafter referred to as "fan airflow") will be explained in the order of (3-1) first configuration, (3-2) second configuration, and (3-3) third configuration. Furthermore, the control of the airflow of the transport fan 120 and the airflow of the heat exchange ventilation fan 104 (hereinafter referred to as "heat exchange supply airflow") will be explained in (3-4) fourth configuration. As an example, one controller for controlling the air conditioner 300 and the transport fan 120 will be illustrated below. If it is possible to control each airflow, a separate controller for controlling the air conditioner 300 and a separate controller for controlling the transport fan 120 may be provided. (3-1) First configuration In the first configuration, the air conditioning airflow of the air conditioner 300 is adjusted to match the fan airflow of the transport fan 120. Figures 5(a) and 5(b) show the first configuration of the controller 460 in the air conditioning system 1000. As shown in Figure 5(a), the air conditioning system 1000 includes the transport fan 120, the air conditioner 300, the temperature sensor 450, and the controller 460. The controller 460 also includes a room temperature acquisition unit 462, a fan airflow control unit 466, a fan airflow acquisition unit 468, and an air conditioning airflow 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 "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 airflow of the transport fan 120 to the controller 460.

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

[0037] The fan airflow control unit 466 receives the room temperature from the room temperature acquisition unit 462. Figure 5(b) is an example of a table held by the fan airflow control unit 466. As shown in the figure, room temperature and fan airflow are associated. The fan airflow control unit 466 determines the fan airflow by referring to the table based on the acquired room temperature. Returning to Figure 5(a), if the determined fan airflow is less than the air conditioning airflow, the air conditioning airflow control unit 472 sets the air conditioning airflow to be less than or equal to 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 less than or equal to 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 load on the air conditioner 300 can be suppressed while delivering conditioned air 210 to each room. (3-2)Second configuration In the second configuration, the fan airflow of the transport fan 120 is adjusted to match the air conditioning airflow of the air conditioner 300. Figures 6(a)-(b) show the second configuration of the controller 460 in the air conditioning system 1000. As shown in Figure 6(a), the air conditioning system 1000 includes the transport fan 120, the air conditioner 300, the temperature sensor 450, and the 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 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. Air conditioner 30 0 transmits the set air conditioning 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 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). Based on the room temperature and the set temperature, the air conditioning temperature control unit 470 determines the temperature of the air conditioner 300 (hereinafter referred to as "air conditioning temperature"). Known techniques 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. Figure 6(b) is an example of a table held by the air conditioning airflow control unit 472. As shown in the figure, room temperature and air conditioning airflow are associated. Based on the acquired room temperature, the air conditioning airflow control unit 472 refers to the table and determines the air conditioning airflow. Returning to Figure 6(a), if the determined air conditioning airflow is greater than the fan airflow, the fan airflow control unit 466 sets the fan airflow to be 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, "setting the fan airflow to be 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 acquired by the air conditioning airflow acquisition unit 464 equal to the fan airflow, the air-conditioned 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 airflow of the transport fan 120 and the air conditioning airflow of the air conditioner 300 are adjusted together. Figures 7(a)-(b) show the third configuration of the controller 460 in the air conditioning system 1000. As shown in Figure 7(a), the air conditioning system 1000 includes the transport fan 120, the air conditioner 300, the temperature sensor 450, and the controller 460. The controller 460 also includes a room temperature acquisition unit 462 and an airflow 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 it from the temperature sensor 450. The airflow control unit 474 receives the room temperature from the room temperature acquisition unit 462. Figure 7(b) is an example of a table held by the airflow control unit 474. As shown in the figure, the air conditioning airflow rate and the fan airflow rate are associated with the room temperature. Here, for the same room temperature, the fan airflow rate is set to be greater than or equal to the air conditioning airflow rate. Based on the acquired room temperature, the airflow control unit 474 refers to the table to determine the air conditioning airflow rate and the fan airflow rate. The airflow control unit 474 adjusts the air conditioning airflow rate of the air conditioner 300 and the fan airflow rate of the transport fan 120 by transmitting the determined air conditioning airflow rate to the air conditioner 300 and the determined fan airflow rate to the transport fan 120. (3-4) Fourth configuration In the fourth configuration, the fan airflow of the transport fan 120 is adjusted to match the heat exchange supply airflow of the heat exchange ventilation fan 104. Figures 8(a) and 8(b) show the 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 a heat exchange ventilation fan 104, a transport fan 120, and a controller 460. The controller 460 also includes a heat exchange supply airflow storage unit 478, a heat exchange supply airflow acquisition unit 476, and a fan airflow control unit 466a.

[0041] The heat exchange supply air volume memory unit 478 stores the setting of the heat exchange supply air volume generated by the heat exchange ventilation fan 104. The heat exchange supply air volume memory unit 478 stores, for example, the setting according to the size of the house 500 during construction. The system stores the predetermined settings for the heat exchange ventilation fan 104.

[0042] The heat exchange supply airflow rate acquisition unit 476 acquires the heat exchange supply airflow rate by receiving the heat exchange supply airflow rate setting from the heat exchange ventilation fan 104. Alternatively, as shown in Figure 8(b), it may receive the heat exchange supply airflow rate setting stored in the heat exchange supply airflow rate storage unit 478.

[0043] The fan airflow control unit 466a controls the transport fan 120 based on the heat exchange supply airflow rate received from the heat exchange supply airflow rate acquisition unit 476. If the heat exchange supply airflow rate is greater than the fan airflow rate, the fan airflow control unit 466a sets the fan airflow rate to be equal to or greater than the heat exchange supply airflow rate. The fan airflow 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.

[0044] Furthermore, the fourth configuration is primarily a method for controlling the lower limit of the fan airflow, and is effective as a means of ensuring the fan airflow necessary to supply all the supply air 208 to each room even when the air conditioner 300 is stopped during the transitional seasons of spring and autumn, resulting in zero air conditioning airflow. Therefore, by using it in combination with (3-1) the first configuration, (3-2) the second configuration, and (3-3) the third configuration, it becomes possible to control the airflow of each piece of equipment to provide sufficient air conditioning and ventilation throughout the year.

[0045] The subject of the apparatus, system, or method in this disclosure comprises a computer. The functions of the subject of the apparatus, system, or method in this disclosure are realized by the computer executing a program. The computer comprises a processor as its main hardware component, which operates according to the program. The processor is of any type as long as it can realize its functions by executing the program. The processor consists of one or more electronic circuits, including semiconductor integrated circuits (ICs) or LSIs (Large Scale Integrations). Multiple electronic circuits may be integrated on one chip or provided on multiple chips. Multiple chips may be aggregated in one device or provided on multiple devices. The program is recorded on a non-temporary recording medium such as a ROM, optical disc, or hard disk drive that is readable by the computer. The program may be pre-stored on the recording medium or supplied to the recording medium via a wide-area communication network, including the Internet.

[0046] According to this embodiment, the adapter 400 connects the air outlet 320 of the air conditioner 300 with the ceiling opening 122 provided in the ceiling of the common space 14, suppressing leakage of conditioned air 210 into the common space 14. Therefore, even when the air conditioner 300 is installed in the common space 14, a decrease in the efficiency of the air conditioning can be suppressed. Furthermore, because the adapter 400 is used, even when a general-purpose air conditioner 300 is used, diagonally downward-blowing air can be supplied to each room 10. Also, because the adapter 400 is used, even when the common space 14 is used as an air-conditioned room, a large temperature difference between the common space 14 and each room 10 can be suppressed. In addition, because a large 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 connected to the ceiling opening 122 and transports the conditioned air 210 to the living room 10, the adapter 400 can efficiently transport the conditioned air 210 from the air conditioner 300. In addition, the adapter 400 has a ventilation space 408 surrounded by a leak-proof bottom surface 402, a leak-proof top surface 404, and two leak-proof side surfaces 406, so that the leakage of conditioned air 210 into the common space 14 can be suppressed. Furthermore, since the downstream end fixing part 410 fixes the downstream end of the adapter 400 to the ceiling, the leakage of conditioned air 210 into the common space 14 can be suppressed. Furthermore, since the upstream end fixing part 412 fixes the upstream end of the adapter 400 to at least one of the wall or the air conditioner 300, the leakage of conditioned air 210 into the common space 14 can be suppressed.

[0048] Furthermore, since the adapter 400 is fixed with the air conditioning intake port 310 exposed to the common space 14, the circulating RA206 in the common space 14 can be drawn into the air conditioning intake port 310. In addition, since an inlet opening 414 is provided in the leak-proof top surface 404, the circulating RA206 is allowed to flow into the ventilation space 408, thereby suppressing an increase in the load on the air conditioner 300. Furthermore, the size of the inlet opening 414 can be adjusted by the inlet opening adjustment unit, so the amount of circulating RA206 flowing into the ventilation space 408 can be adjusted. In addition, since the air conditioning intake port 310 is provided at the upper end of the air conditioner 300, and the inlet opening 414 is located at the upstream end of the leak-proof top surface 404 and below the air conditioning intake port 310, the occurrence of short circuits can be avoided.

[0049] Furthermore, since the leak-proof bottom surface 402 is equipped with a maintenance opening 418 and an opening / closing panel section 420, maintenance of the air conditioner 300 can be performed while the adapter 400 is attached to the air conditioner 300. In addition, since it is equipped with a filter 422, the circulating RA206 can be purified. In addition, since a ventilation gap 424 is provided between the filter 422 and the air conditioner 300, the effective area of ​​the filter 422 can be secured. Furthermore, since the heat exchange ventilation fan 104 blows the supply air 208 from the heat exchange outlet 112 into the common space 14, the temperature difference between the common space 14 and the supply air 208 can be reduced. In addition, since the heat exchange outlet 112 is provided vertically above the air conditioner 300, the supply air 208 can be efficiently drawn into the conditioned air 210.

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

[0051] In the embodiments of this disclosure, as an example, a case in which an air conditioner 300 is installed in a common space 14, which is a corridor, has been described as shown in Figure 1. However, the installation location of the air conditioner 300 is not limited to a corridor. It may be installed anywhere in the common space 14 adjacent to a living room 10 that constitutes a 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 living room 10e. Here, Figure 11 is a schematic diagram showing the configuration when the air conditioner 300 and branching chamber 400 are installed in the storage space 520.

[0052] In Figure 11, the corridor 510 is a common space 14 and is adjacent to each room, including room 10e, in a way that allows for ventilation. Also, the storage space 520 is a common space 14 and is adjacent to one of the rooms 10e in a way that allows for 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.

[0053] A living room 10e and a storage space 520 are adjacent to each other, separated by a door 532. Here, the door 532 can be opened and closed, and it connects the common space 14 and the living room 10 in a way that allows for ventilation.

[0054] The storage space 520 is divided into an upper and lower section by a storage top plate 521 that is installed parallel to the floor. The space above the storage top plate 521 is designated as the storage overhead compartment 522, and the space below the storage top plate 521 is designated as the storage lower compartment 523. In Figure 12, the air conditioner 300 and adapter 400 are installed in the storage overhead compartment 522, which is the upper part of the storage space 520.

[0055] In this configuration, air from each room first flows into a certain room 10e via the corridor 510. Furthermore, the air from each room is ventilated through a certain room 10e to the storage space 520, which can then be air-conditioned by the air conditioner 300. The conditioned air is then guided via the adapter 400 to the transport fan 120 in the ceiling space 16 and transported to each room. Note that the storage space 520 and corridor 51 are located in the wall section 534. A ventilation opening 536, which is an opening that allows ventilation between the corridor 510 and the storage space 520, may be provided. With such a configuration, the air from each room that has been ventilated into the corridor 510 can be directly drawn into the storage space 520 from the corridor 510 for air conditioning.

[0056] Furthermore, in the embodiments of this disclosure, as an example, a case in which conditioned air 210 is transported from the ceiling space 16 to the living room 10 has been described as shown in Figure 2, but the invention is not limited to this form. For example, as shown in Figure 12, a communication duct 135 that connects the ceiling space 16 and the underfloor space 17 may be installed to transport the conditioned air 210 from the underfloor space 17 to the living room 10. Here, Figure 12 is a schematic diagram showing the configuration when conditioned air 210 is transported using the underfloor space 17. In Figure 12, the transport fan 120 is located in the ceiling space 16, and the branching chamber 140 is located in the underfloor space 17. In Figure 12, the communication duct 135 is further provided as an air passage for the air conditioning system 1000.

[0057] The connecting duct 135 is an air passage that connects the space above the ceiling of the common space 14, known as the ceiling space 16, with the space below the floor of the common space, known as the underfloor space 17. One end of the connecting duct 135 is connected to the outlet of a transport fan 120 installed in the ceiling space 16, and the other end is connected to a branching chamber 140 installed in the underfloor space 17. This configuration transports the conditioned air 210 blown out from the transport fan 120 from the ceiling space 16 to the underfloor space 17. The connecting duct 135 can be constructed in any way as long as it can transport the conditioned air 210 from the ceiling space 16 to the underfloor space 17. For example, as shown in Figure 12, the connecting duct 135 may be constructed to pass through the common space 14, or it may be constructed to pass through the walls of the house 500 (in other words, without passing through the common space 14 or the living rooms 10).

[0058] In this configuration, the conditioned air 210 blown out from the air conditioner 300 is first guided to the transport fan 120 in the ceiling space 16 via the adapter 400. Next, the conditioned air 210 blown out from the transport fan 120 moves from the ceiling space 16 side to the underfloor side 17 through the communication duct 135. Then, the conditioned air 210 is transported to each living room 10 via the branching chamber 140 installed on the underfloor side 17. With this configuration, the living rooms 10 can be air-conditioned from the underfloor side 17. In particular, when the air conditioner 300 is used for heating, the property of warm air to rise can be utilized to heat the entire living room 10.

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

[0060] In Figure 13, the storage top panel 521 is considered the ceiling of the storage space 520 (common space 14), and the storage overhead compartment 522 is considered the space above the ceiling 16. In this configuration, a ceiling opening 122 is provided in the storage top panel 521, an air conditioner 300 and adapter 400 are installed in the storage lower compartment 523, and a transport fan 120 is installed in the storage overhead compartment 522. The branching chamber 140 is installed in the underfloor space 17. Furthermore, one end of the communication duct 135 is connected to the outlet of the transport fan 120 installed in the storage overhead compartment 522, and the other end is connected to the branching chamber 140 installed in the underfloor space 17.

[0061] In this way, when the storage space 520 is divided into an upper storage compartment 522 side and a lower storage compartment 523 side by the storage top plate 521, the storage top plate 521 may be considered as the ceiling and the upper storage compartment 522 as the space above the ceiling 16 when installing the air conditioning system 1000. In other words, if there is a top plate that spatially divides the common space 14 into upper and lower parts, the top plate may be considered as the ceiling and the upper space as the space above the ceiling 16.

[0062] Even with this configuration, the conditioned air 210 blown out from the transport fan 120 can be transported from the storage compartment 522 side, which is considered to be the space above the ceiling 16, to the underfloor area 17 side. In addition, even if the space above the ceiling of the common space 14 is narrow, the installation of the air conditioning system 1000 can be made easier.
