Description

[Technical Field]

[0001] The present disclosure relates to air conditioning technology, and more particularly to an air conditioning system that controls the air conditioning of 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 cools and heats the common space, and performs air conditioning to maintain a comfortable temperature environment in the common space. 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 air conditioning in each room will be less uneven and the temperature environment will be more stable (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-148382 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 minimizes the reduction in effective area and the increase in costs 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 that is blown diagonally downward to each room. To achieve this, an adapter is used to connect the transport fan that supplies air to each room to the general-purpose air conditioner. It is desirable to simplify the installation of the adapter.

[0005] The present disclosure has been made in consideration of these circumstances, and its purpose is to provide a technology that simplifies the installation of an adapter for connecting a transport fan to an air conditioner. [Means for solving the problem]

[0006] To solve the above problems, an air conditioning system according to one aspect of the present disclosure includes an air conditioner installed in a wall of a common space separate from the living rooms that make up the living space, the air conditioner drawing in air from the common space through an air conditioning inlet and blowing out conditioned air from an air conditioning outlet, a transport fan communicating with a ceiling opening provided in the ceiling of the common space to draw in the conditioned air and transport the conditioned air to the living rooms, an adapter communicating between the air conditioning outlet and the ceiling opening and preventing the conditioned air from leaking into the common space, and a joint member connecting the transport fan and the adapter. The joint member has a connecting opening connectable to the inlet of the transport fan, the inner size of the connecting opening being larger than the size of the inlet. [Effects of the Invention]

[0007] According to the present disclosure, the installation of an adapter for connecting a blower and an air conditioner can be simplified. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 1 is a top view showing the configuration of a house in which an air conditioning system according to this embodiment is installed. [Figure 2] 2(a) and 2(b) are perspective views showing the configuration of the air conditioning system of FIG. [Figure 3] FIG. 3 is a perspective view showing the configuration of the adapter of FIGS. [Figure 4] FIG. 3 is an exploded perspective view showing the configuration of the air conditioning system of FIGS. 2(a)-(b). [Figure 5] 2(a)-(b) are diagrams showing the connection state of the adapter in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] Before describing specific embodiments of the present disclosure, an overview of the embodiments will be provided. This embodiment relates to an air conditioning system that performs whole-house air conditioning in a residence having a common space and multiple living rooms. The air conditioning system does not use dedicated air-conditioning rooms and dedicated air conditioners to prevent a reduction in effective area and an increase in costs. Therefore, the air conditioning system installs general-purpose air conditioners in common spaces, such as hallways, and uses the common spaces as air-conditioning rooms. Furthermore, a transport fan is installed in a ceiling opening in the common space, and the transport fan transports air from the common space to each living room via ducts. In such a situation, as described above, it is difficult to supply air blown diagonally downward to each living room. To address this issue, the air conditioning system attaches an adapter to the air conditioner, which covers at least the bottom and front sides of the air conditioner and directs the air blown downward from the air conditioner to the ceiling opening.

[0010] There is also a demand for simplified installation of the adapter. To this end, in air conditioning systems, the conveying fan and the adapter are connected via a joint member, and the inside size of the opening of the joint member is made larger than the size of the intake port of the conveying fan. This makes it possible to connect the conveying fan and the adapter by using the joint member even if the positions of the conveying fan and the adapter are misaligned horizontally.

[0011] The examples described below each illustrate a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component placement and connection configurations, steps (processes), and step order shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, components that are not described in the independent claims that represent the highest concept of the present disclosure are described as optional components. Furthermore, in each figure, substantially identical components are designated by the same reference numerals, and redundant descriptions are omitted or simplified.

[0012] FIG. 1 is a top view showing the configuration of a house 500 in which an air conditioning system 1000 is installed. The house 500 may be a single-family residence in an apartment building or other collective housing complex, or it may be a detached house. The house 500 includes first living room 10a to fourth living room 10d, collectively referred to as living rooms 10, and a common space 14. The living rooms 10 constitute the living space. The common space 14 is, for example, a passageway such as a hallway or entrance, or a storage space such as a closet, and is a space separate from the living rooms 10. The common space 14 and the living rooms 10 are connected to allow ventilation, and air circulates from each living room 10 to the common space 14.

[0013] The air conditioning system 1000 includes an outside air inlet 100, an outside air introduction duct 102, a heat exchange ventilation fan 104, an exhaust duct 106, an exhaust port 108, a heat exchange duct 110, a heat exchange outlet 112, a transport fan 120, a transport duct 130, a branch chamber 140, a first branch transport duct 142a to a seventh branch transport duct 142g collectively referred to as branch transport ducts 142, a first outlet 144a to a seventh outlet 144g collectively referred to as outlets 144, and an air conditioner 300. The outside air introduction duct 102, the exhaust duct 106, the heat exchange duct 110, the transport duct 130, and the branch transport duct 142 are pipes that transport air, that is, air paths.

[0014] 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 interior of the house 500 is connected to a heat exchange type ventilation fan 104. The heat exchange type ventilation fan 104 is disposed, for example, in the ceiling (not shown) 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. A heat exchange duct 110 is also connected to the heat exchange type ventilation fan 104.

[0015] The heat exchanger ventilation fan 104 takes in outside air from the outside air inlet 100 through the outside air inlet duct 102. The outside air drawn in through the outside air inlet 100 corresponds to supply air. The heat exchanger ventilation fan 104 also takes in ventilation return air (RA) through a ventilation opening (not shown). The ventilation return air is indoor air flowing in from the interior of the house 500, for example, from rooms including the living room 10 and the common space 14. The heat exchanger ventilation fan 104 exchanges heat between them. As a result of the heat exchange, the heat exchanger ventilation fan 104 discharges exhaust air from the exhaust port 108 through the exhaust duct 106. The heat exchanger ventilation fan 104 also discharges the heat-exchanged supply air (outside air) through the heat exchanger duct 110 and the heat exchanger outlet 112. The heat exchanger outlet 112 is an opening provided in the ceiling of the common space 14. That is, the heat exchange ventilation fan 104 blows out supply air (heat exchange supply air), which is outside air that has exchanged heat with ventilation air RA exhausted from the living space, from the heat exchange outlet 112 into the common space 14.

[0016] The air conditioner 300 is installed on the wall of the common space 14, not in an air-conditioned room. An air conditioning inlet (not shown) is provided in the upper part of the air conditioner 300. The air conditioning inlet draws in supply air from a heat exchanger outlet 112 provided vertically above the air conditioner 300. In addition, circulating RA flows into the air conditioning inlet from the common space 14, which is inside the house 500. Like ventilation RA, circulating RA corresponds to 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 RA and supply air. The air conditioner 300 controls the temperature, humidity, etc. of the circulating RA and supply air to achieve a set temperature (hereinafter referred to as the "set temperature"). An air conditioning outlet (not shown) is provided in the lower part of the air conditioner 300, and the air conditioner 300 blows out conditioned air (conditioned air) from the air conditioning outlet. That is, the air conditioner 300 draws air from the common space 14 through the air conditioning inlet and blows out conditioned air from the air conditioning outlet.

[0017] A ceiling opening (not shown) is provided in the ceiling of the common space 14. A transport fan 120 installed above the ceiling draws in conditioned air and circulating RA (hereinafter, these may also be referred to as "conditioned air") through the ceiling opening. The transport fan 120 is connected to the branch chamber 140 via a transport duct 130, and transports the conditioned air to the branch chamber 140.

[0018] The branch chamber 140 is installed in the ceiling and is connected to the transfer fan 120 as well as the first branch transfer duct 142a to the seventh branch transfer duct 142g. The first branch transfer duct 142a is connected to the first air outlet 144a installed in the first living room 10a, and the second branch transfer duct 142b is connected to the second air outlet 144b installed in the second living room 10b. The third branch transfer duct 142c is connected to the third air outlet 144c installed in the third living room 10c, and the fourth branch transfer duct 142d is connected to the fourth air outlet 144d installed in the fourth living room 10d. The fifth branch transfer duct 142e is connected to the fifth air outlet 144e installed in the first living room 10a, and the sixth branch transfer 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 installed in the fourth room 10d.

[0019] The transport fan 120 transports the conditioned air from the first room 10a to the fourth room 10d via the transport duct 130, the branch chamber 140, the first branch transport duct 142a to the seventh branch transport duct 142g, and the first air outlets 144a to the seventh air outlets 144g. Each air outlet 144 is installed on the side wall or ceiling of each room 10 and discharges the conditioned air blown by the transport fan 120 into each room 10. Since each room 10 is connected to the common space 14, the conditioned air blown out from the air outlets 144 also circulates in the common space 14. A portion of the circulated air flows into the air conditioner 300 as circulated air (RA). The circulated air may also flow into the transport fan 120 through a ceiling opening. Another portion of the circulated air is taken into the heat exchanger ventilation fan 104 as ventilation air (RA).

[0020] When conditioned air blown out from the air conditioning outlet of the air conditioner 300 is diffused into the common space 14, the amount of conditioned air drawn into the conveying fan 120 through the ceiling opening decreases. This reduces the amount of conditioned air supplied to each room 10, thereby reducing air conditioning efficiency. To prevent this reduction in air conditioning efficiency, in this embodiment, an adapter, described below, is installed in the common space 14. The adapter connects the air conditioning outlet of the air conditioner 300 with the ceiling opening, and prevents conditioned air from leaking into the common space 14. When leakage of conditioned air into the common space 14 is reduced, the reduction in the amount of conditioned air drawn into the conveying fan 120 through the ceiling opening is also reduced.

[0021] 2(a)-(b) are perspective views showing the configuration of the air conditioning system 1000. FIG. 2(b) shows a view from below that of FIG. 2(a). An attic space 16 is arranged above the common space 14. The heat exchange duct 110, transport fan 120, transport duct 130, and branch chamber 140 described above are installed in the attic space 16. An air conditioner 300 is also installed in the wall 20 of the common space 14. A ceiling opening 122 is also provided in the ceiling, and the common space 14 and the attic space 16 are connected by the ceiling opening 122. The transport fan 120 is also arranged above the ceiling opening 122. Hereinafter, the direction away from the wall 20 in the common space 14 will be referred to as the "front" direction, and the direction toward the wall 20 in the common space 14 will be referred to as the "rear" direction.

[0022] An air conditioning inlet 310 is provided in the upper part of the air conditioner 300, which draws in air from the common space 14. As described above, an air conditioning outlet (not shown) is provided in the lower part of the air conditioner 300, and an adapter 400 is provided to cover this. The air conditioner 300 blows conditioned air from the air conditioning outlet into the adapter 400.

[0023] As described above, the adapter 400 connects the air conditioning outlet of the air conditioner 300 with the ceiling opening 122, preventing conditioned air from leaking into the common space 14. Here, FIG. 3 will also be described to explain the structure of the adapter 400. FIG. 3 is a perspective view showing the configuration of the adapter 400. The adapter 400 has a box-like shape and is surrounded by a bottom surface 402 on the lower side, side surfaces 406 on both sides, a front surface 408 on the front side, a first sloped surface 414 on the upper side, a top surface 416, and a second sloped surface 418. The bottom surface 402 includes an upward sloped surface 410. The upward sloped surface 410 is located between the bottom surface 402 and the front surface 408 and rises upward as it moves forward. The first sloped surface 414, the top surface 416, and the second sloped surface 418 are arranged in order in the left-right direction. First inclined surface 414 and second inclined surface 418 are surfaces that rise upward as they proceed from the end side of adapter 400 toward top surface 416. A cylindrical adapter tubular portion 420 is provided on top surface 416. The interior of adapter 400 and the interior of adapter tubular portion 420 are in communication.

[0024] The upper rear portion of adapter 400 and the rear portion of adapter 400 open as suction opening 440. Suction opening 440 is located on the air conditioner 300 side of adapter 400, and the lower portion of air conditioner 300 is fitted into suction opening 440. In such a situation, the air conditioning outlet of air conditioner 300 is located inside adapter 400. Furthermore, a lower edge 442 is located at the lower portion of suction opening 440, and an upper edge 444 is located at the upper portion of suction opening 440.

[0025] A joint member 600 is connected to the adapter cylindrical portion 420, and the joint member 600 is connected to the transfer fan 120. In other words, the joint member 600 is disposed inside the ceiling opening 122 and connects the transfer fan 120 and the adapter 400. The joint member 600 has a cylindrical shape. The transfer fan 120 communicates with the ceiling opening 122 provided in the ceiling of the common space 14, and draws in conditioned air from the air conditioner 300 via the adapter 400 and the joint member 600. The transfer fan 120 transfers the conditioned air from the transfer duct 130 to the branch chamber 140.

[0026] Although the positional relationship between the transport fan 120 and the air conditioner 300 is specified, this positional relationship may deviate during actual installation. To simplify the installation of the adapter 400 for connecting the transport fan 120 and the air conditioner 300, it is desirable to allow some degree of deviation in the positional relationship that occurs during installation. Below, installation of the air conditioning system 1000 in the house 500 will be described with reference to Figures 4 and 5. Figure 4 is an exploded perspective view showing the configuration of the air conditioning system 1000. Figure 4 is shown in the same way as Figure 2(b).

[0027] (1) The transport fan 120 is installed in the ceiling space 16 so that the air inlet 124 arranged on the lower surface of the transport fan 120 faces the ceiling opening 122. The air inlet 124 has a circular shape. (2) Air conditioner 300 is installed on wall 20 of common space 14. At this time, the positional relationship in which air conditioner 300 should be installed relative to transport fan 120 or ceiling opening 122 is determined in advance, and air conditioner 300 is installed at a position on wall 20 that is close to this positional relationship. Air conditioner intake 310 is arranged in the upper part of air conditioner 300, and air conditioner outlet 320 is arranged in the lower part of air conditioner 300.

[0028] (3) The joint member 600 has a rectangular connecting top plate 602 disposed on its upper portion, and a cylindrical joint tube portion 610 disposed below the connecting top plate 602. The connecting top plate 602 has a circular connecting opening 604 that communicates with the suction opening 612 of the joint tube portion 610. The connecting opening 604 is connectable to the suction port 124 of the conveying fan 120. Here, the inner size of the connecting opening 604 is made larger than the size of the suction port 124 to allow for misalignment, particularly horizontal misalignment, that occurs during installation. The joint member 600 is temporarily fixed to the conveying fan 120 while aligning the connecting opening 604 with the suction port 124. The temporary fixation is achieved, for example, by connecting the connecting top plate 602 and the conveying fan 120 with double-sided tape.

[0029] (4) A wall fixing member 40 is temporarily fixed to a wall 20 on which the air conditioner 300 is installed, at a position below the air conditioner 300. The wall fixing member 40 is a member having a U-shaped cross section. The temporary fixing is achieved, for example, by connecting the wall 20 and the wall fixing member 40 with double-sided tape. By inserting a lower edge 442 of the adapter 400 into the wall fixing member 40, the adapter 400 is attached to the wall fixing member 40 so that the suction opening 440 covers the lower part of the air conditioner 300. Here, the width of the suction opening 440 is set to be equal to or greater than the width of the air conditioning outlet 320, the lower edge 442 of the suction opening 440 is connected to the wall fixing member 40, and the upper edge 444 of the suction opening 440 is positioned below the air conditioning inlet 310 (top surface) of the air conditioner 300. At this time, it is preferable that the upper edge 444 abuts against the air conditioner 300 above the air conditioning outlet 320. With this configuration, the intake opening 440 of the adapter 400 is in close contact with the air conditioner 300 while surrounding the air conditioning outlet 320. In other words, it is possible to reliably prevent the conditioned air blown out from the air conditioning outlet 320 from leaking into the common space.

[0030] In this state, it is confirmed whether the connection opening 422 of the adapter tubular part 420 and the suction opening 612 of the joint tubular part 610 can be aligned. Whether the connection opening 422 and the suction opening 612 can be aligned is confirmed by determining whether the catch clip first member 430 and the catch clip second member 630 can be connected after combining the adapter tubular part 420 and the joint tubular part 610. The catch clip first member 430 is disposed on the side surface of the adapter tubular part 420, and the catch clip second member 630 is disposed on the side surface of the joint tubular part 610. The combination of the catch clip first member 430 and the catch clip second member 630 is the catch clip. Furthermore, at least one of the catch clip first member 430, the catch clip second member 630, and the catch clip is referred to as a "joint fixing member."

[0031] Catch clip first member 430 has a fixed portion fixed to the underside of the bottom plate portion, an operable lever portion that is integral with the fixed portion, and a hook portion that moves when the lever portion is operated. Furthermore, catch clip second member 630 has an engaging portion that can engage with the hook portion of catch clip first member 430. With the hook portion of catch clip first member 430 engaged with the engaging portion of catch clip second member 630, the lever portion of catch clip first member 430 is hooked onto the fixed portion, thereby connecting catch clip first member 430 and catch clip second member 630.

[0032] If it is confirmed that the connection opening 422 and the suction opening 612 cannot be aligned, the temporary fixing position between the joint member 600 and the conveying fan 120 is shifted, or the temporary fixing position between the wall 20 and the wall fixing member 40 is shifted. If it is confirmed that the connection opening 422 and the suction opening 612 can be aligned, the fixing positions between the joint member 600 and the conveying fan 120 and the fixing positions between the wall 20 and the wall fixing member 40 are determined. In other words, the adapter 400 is positioned by the combination of the catch clip first member 430 and the catch clip second member 630 and the combination of the lower edge 442 and the wall fixing member 40.

[0033] (5) A plurality of through holes 606 are provided in the connection top plate 602 of the joint member 600. At the position determined in (4) above, that is, the position where the adapter 400 and the joint member 600 are combined, the joint member 600 and the transport fan 120 are screwed together via the through holes 606. This fixes the joint member 600 to the transport fan 120.

[0034] (6) The wall 20 and the wall fixing member 40 are connected at the position determined in (4) above. Screws may also be used to connect the wall 20 and the wall fixing member 40. The adapter 400 is then attached to the wall fixing member 40. This fixes the adapter 400 to the wall 20.

[0035] (7) After combining the adapter tubular portion 420 and the joint tubular portion 610, the catch clip first member 430 and the catch clip second member 630 are connected, whereby the adapter 400 and the joint member 600 are connected.

[0036] The connection portion between the adapter 400 and the wall 20 and the connection portion between the adapter 400 and the joint member 600 will be described in more detail below. FIG. 5 is a diagram showing the connected state of the adapter 400. As described above, the adapter 400 and the wall fixing member 40 are connected by inserting the lower edge portion 442 of the adapter 400 into the wall fixing member 40. At the connection portion between the adapter 400 and the wall fixing member 40, a convex protrusion 46 is provided on the wall fixing member 40, and a concave recess 446 is provided on the adapter 400. The engagement of the protrusion 46 and the recess 446 strengthens the connection between the adapter 400 and the wall fixing member 40. A recess may be provided on the wall fixing member 40, and a protrusion may be provided on the adapter 400.

[0037] As described above, the adapter 400 and the joint member 600 are connected by combining the adapter tubular portion 420 and the joint tubular portion 610. At the connection portion between the adapter 400 and the joint member 600, a convex convex portion 448 is provided on the adapter tubular portion 420, and a concave concave portion 648 is provided on the joint tubular portion 610. The convex portion 448 and the concave concave portion 648 are fitted together to strengthen the connection between the adapter 400 and the joint member 600. A concave portion may be provided on the adapter tubular portion 420, and a convex portion may be provided on the joint tubular portion 610.

[0038] According to this embodiment, the inner size of the connection opening 604 of the joint member 600 is larger than the size of the suction port 124 of the transport fan 120, so the adapter 400 can be installed even if the positions of the transport fan 120 and the air conditioner 300 are misaligned. Furthermore, because the inner size of the connection opening 604 of the joint member 600 is larger than the size of the suction port 124 of the transport fan 120, construction can be simplified when installing the adapter 400 to connect the transport fan 120 and the air conditioner 300. Furthermore, the joint member 600 has through holes 606 for screwing the joint member 600 and the transport fan 120 together, so the transport fan 120 and the joint member 600 can be connected while the relative positions of the transport fan 120 and the joint member 600 are misaligned.

[0039] Furthermore, because the adapter 400 is positioned by the joint fixing member and the wall fixing member 40, positioning can be simplified. Furthermore, at the connection portion between the adapter 400 and the joint member 600, a convex portion is provided on one side and a concave portion is provided on the other side, thereby strengthening the connection. Furthermore, at the connection portion between the adapter 400 and the wall fixing member 40, a convex portion is provided on one side and a concave portion is provided on the other side, thereby strengthening the connection. Furthermore, because the width of the intake opening 440 is equal to or greater than the width of the air conditioning outlet 320, the lower edge 442 is connected to the wall fixing member 40, and the upper edge 444 is positioned below the top surface of the air conditioner 300, the vertical position of the adapter 400 can be adjusted by raising or lowering the vertical position of the wall fixing member 40, thereby simplifying the vertical positioning of the adapter 400, which is determined by the connection to the conveying fan 120.
