Description

[Technical Field]

[0001] The present invention relates to an air conditioning system that is configured to efficiently and economically heat and cool multiple rooms using a single air conditioner installed in the living room of an apartment building or the like. [Background technology]

[0002] As a way to minimize the costs associated with heating and cooling a residence and the waste of energy used in heating and cooling, consideration is being given to heating and cooling multiple rooms using an air conditioner or other air conditioning unit installed in a single room.

[0003] In particular, in recent years, the performance of air conditioners has improved, and high-performance air conditioners that are highly efficient in heating and cooling and save energy have come into use.

[0004] Patent Document 1 discloses an air conditioning mechanism that is capable of ventilating and air-conditioning all rooms, is easy to install, and produces little noise. The air conditioning mechanism has an outlet duct installed in the indoor unit of the air conditioner, and is installed in the living room. The living room and multiple private rooms are connected via intermediate ducts, and the intermediate ducts are fitted with ventilation means that blow air from the living room side to the private rooms. The air sent by the intermediate ducts flows out from the private rooms into the corridor, and an intake duct that draws air in at the intake part and an exhaust duct that has the function of exchanging air with some fresh outside air are connected to the indoor unit.

[0005] Patent Document 2 also discloses an air conditioning system that can adequately air-condition an entire floor with a single small-capacity room air conditioner, which is installed on the same floor of a building where multiple rooms are located adjacent to a corridor, and which includes an air conditioning equipment space located above a non-residential space other than the corridor and other than the space where residents are constantly present, an air conditioning equipment installed inside the air conditioning equipment space, an air supply space located above the corridor, a connecting passage connecting the air conditioning equipment space and the air supply space, and an air supply duct 7 connecting the air supply space and multiple rooms, thereby ensuring sufficient ceiling height in the corridor.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 10-170048 [Patent Document 2] Japanese Patent Publication No. 2022-142985 Summary of the Invention [Problem to be solved by the invention]

[0007] Especially in apartment buildings, the number of floors is limited, so ceiling heights are generally low. However, there is a desire to make ceiling heights as high as possible in living rooms and other dwellings, leaving aside hallways, toilets, bathrooms, and washrooms, to create a sense of openness. As a result, ceiling depths in living rooms and other dwellings tend to be shallow.

[0008] On the other hand, the ceiling depth is shallow, which means there is no space to install large diameter round ducts. For example, if you want to use one air conditioner installed in the living room to heat and cool other rooms, installing a standard duct would result in a lowered ceiling in the living room, which would reduce the market value of the apartment.

[0009] The present invention aims to solve the problems described above and provides an air conditioning system that can efficiently and economically heat and cool multiple rooms in an apartment building using a single air conditioner installed in the living room without compromising the livability of the living room. [Means for solving the problem]

[0010] The present invention is directed to an air conditioning system for a dwelling unit in an apartment building having a first area containing multiple living rooms, which has a relatively high ceiling height and a shallow ceiling depth, and a second area containing a corridor, which has a relatively low ceiling height and a deeper ceiling depth than the first area.The air conditioning system is configured so that an air conditioner is installed in each living room that constitutes the first area, and the air conditioned by the air conditioner is distributed to each room in the dwelling unit via one or more blower fans installed in the ceiling depth of the corridor or rooms that constitute the second area.The air intake port, which is composed of a horizontally long intake grille and an intake chamber for taking in conditioned air from the air conditioner, is installed in a position close to the air conditioner on the ceiling surface of the living room in which the air conditioner is installed, and the section from the intake chamber to the ceiling depth of the second area is characterized by the following: multiple small-diameter ducts with diameters smaller than the depth of the ceiling depth of the living room in which the air conditioner is installed, or a wide duct with a rectangular cross-section whose vertical height is smaller than the depth of the ceiling depth of the living room in which the air conditioner is installed and whose left-right width is expanded horizontally based on the width of the air conditioner and the width of the intake grille.

[0011] In the present invention, the term "room" is not limited to the general meaning of "room" but broadly includes closets, bathrooms, toilets, storage spaces, and other partitioned spaces within a dwelling unit.

[0012] With the air conditioning system of the present invention, configured as described above, a single air conditioner installed in a living room or other living room can efficiently and economically heat and cool multiple rooms. However, this does not mean that more than two air conditioners cannot be installed, and additional air conditioners can be installed as needed.

[0013] The distinction between Area 1 and Area 2 indicates that there are areas with relatively high and low ceiling heights, and does not preclude further differences in ceiling height within Area 1 and Area 2. It also does not preclude areas with ceiling heights intermediate between Area 1 and Area 2, or areas of other heights, from coexisting.

[0014] When applying the air conditioning system of the present invention, since the typical ceiling depth in the living area of ​​an apartment building is about 180 mm, it is preferable that the ceiling depth of the first area mentioned above be 150 mm or more and 200 mm or less, and that the ceiling depth of the second area be 400 mm or more and 600 mm or less.

[0015] Furthermore, the distance from the air conditioner installed in the room in the first area to the air intake is preferably 300 mm to 2000 mm, and more preferably about 400 mm to 1400 mm.

[0016] In order to ensure that the air blown out from a single air conditioner provides a uniform air conditioning effect in each room in the dwelling, and to reduce distribution loss from the room where the air conditioner is installed to other rooms, it is preferable to set the airflow direction from the air conditioner to the above-mentioned 300mm or more and 2000mm or less.

[0017] In experiments conducted on an actual residential unit, it was confirmed that the air conditioner could smoothly draw in air and blow it out from the air outlets in multiple rooms when the distance from the air conditioner to the air intake was set to 500mm and 600mm.

[0018] On the other hand, if the distance from the air conditioner to the air intake increases, it becomes difficult to create a smooth air flow simply by adjusting the air outlet direction.

[0019] For rooms other than those where the air conditioner is installed, conditioned air can be taken in through the outlets installed in each room via a branch chamber, a blower fan, and then a RY pipe.

[0020] More specifically, for example, a branch chamber connected to the aforementioned multiple small diameter ducts or wide ducts can be installed in the ceiling pocket of the corridor or room where the second area blower fan is installed, and multiple blower fans can be connected via the branch chamber, or the duct path can be branched via a RY pipe, allowing conditioned air to be sent to each room.

[0021] In order to achieve uniform air conditioning effects in each room within the apartment, sensors can be installed to measure the temperature and humidity in each room, and in addition to adjusting the air conditioner, functions such as adjusting the fan's airflow and opening / closing or adjusting the opening degree of the intake and exhaust vents can be added.

[0022] Furthermore, if the corridor that makes up the second area of ​​the dwelling is configured to run in a straight line from the room where the air conditioner is installed to the entrance, and a ventilation fan is installed in the ceiling pocket of this corridor, the arrangement of ducts and other equipment from the room in the first area to the corridor in the second area will be simple, making air conditioning work easier and enabling more efficient air conditioning. [Effects of the Invention]

[0023] According to the air conditioning system of the present invention, even if the ceiling depth of a room where a high ceiling is desired is shallow, a single air conditioner installed in a living room or other room can efficiently and economically heat and cool multiple rooms.

[Figure 6] FIG. 2 is a perspective view showing an example of a blower fan installed in a ceiling pocket of a corridor. DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 6. Note that the arrangement of each air conditioning device in the illustrated embodiment and the dimensions shown in Figure 4 are merely examples, and the present invention is not limited to these.

[0026] FIG. 1 is a plan view of the layout of air conditioning equipment in one embodiment of an air conditioning system of the present invention, and FIG. 2 is a corresponding schematic diagram of the layout of the air conditioning equipment.

[0027] In this example, a living / dining / kitchen room 11 (hereinafter referred to as "LDK") is located on the veranda or balcony 31 side, and a wall-mounted air conditioner 1 is installed under the ceiling of the LDK 11 on the veranda or balcony 31 side.

[0028] In addition to the living / dining / kitchen area 11, the apartment also has three Western-style rooms 12, 13, and 14, which form the first area with a relatively high ceiling.

[0029] In contrast, a corridor 15 is arranged in a straight line from the living / dining / kitchen area 11 to the entrance 16 located on the side of the shared corridor 32, and in addition to the corridor 15, the toilet 17, washroom 18, and bathroom 19 form the second area with a relatively low ceiling height.

[0030] In addition, two closets, 20 and 21, form a third area with a ceiling height intermediate between these two.

[0031] An example of the dimensions is as follows: Area 1: Ceiling height 2450mm, ceiling recess 180mm, Area 2: Ceiling height 2100mm, ceiling recess 450mm, Third area: Ceiling height 2300mm, ceiling recess 250mm, This becomes:

[0032] The air conditioning equipment that makes up the air conditioning system of the present invention includes, in addition to the air conditioner 1 mentioned above, a horizontally long intake grille 2a and intake chamber 2b (see Figures 3 and 4) that make up the intake port 2 that opens into the ceiling surface of the living, dining, and kitchen 11, a duct 3 that connects the section from this intake port 2 to a branch chamber 4 that is installed in the ceiling pocket of the corridor 15, two blower fans 5 that branch off at the branch chamber 4 and are connected by a duct, outlets (chamber / grill) 7a, 7b, 7c that branch off via two RY pipes 6 and are connected to ducts that head toward the Western-style rooms 12, 13, 14, and an outlet (chamber / grill) 7d in the corridor 15.

[0033] In this embodiment, two blower fans 5 are used via the branch chamber 4, but the number of blower fans 5 may be one, or three or more. Also, there may be cases where the RY pipe 6 is not required.

[0034] In this embodiment, the distance from the air conditioner 1 located under the ceiling on the veranda or balcony 31 side of the living / dining / kitchen kitchen 11 to the horizontal air inlet 2 provided on the ceiling surface of the living / dining / kitchen kitchen 11 is preferably within approximately 500 mm to 2000 mm, as mentioned above, and in the section from the air inlet 2 toward the ceiling recess of the corridor 15, a duct 3 that can be installed in a ceiling recess with a dimension of approximately 180 mm, as shown as an example, will be placed.

[0035] To reduce air conditioning losses in this section, the duct 3 can be constructed by arranging multiple small-diameter ducts 3a in parallel as shown in Figure 4, or by using a wide duct 3b with a rectangular cross section as shown in Figure 5 instead of multiple small-diameter ducts 3a.

[0036] In the case of a wide duct 3b with a rectangular cross section, the air flows smoothly from the horizontally long suction chamber 2b, and since the cross section can be made larger than when multiple small-diameter ducts 3a are connected in parallel, there is an advantage in that pressure loss is small.

[0037] Since the fan 5 is installed in the ceiling of the deep corridor 15, a general air-conditioning blower fan 5 such as that shown in FIG. 6 can be used.

[0038] The outlets 7a, 7b, and 7c that blow conditioned air into the three Western-style rooms 12, 13, and 14 in the first area, which has a high ceiling, can be installed so that they blow air horizontally from the top of the wall of each of the Western-style rooms 12, 13, and 14, penetrating the boundary wall between the adjacent closet 20 in the second area, which has a relatively low ceiling, or the corridor 15 in the third area.

[0039] In this embodiment, the air outlet 7d to the corridor 15 is provided on the ceiling surface of the corridor 15, and is configured to blow air downward.

[0040] With the above configuration, the air taken in from the intake port 2 located close to the air conditioner 1 in the living room, dining room, and kitchen 11 is sent to each room in the dwelling while maintaining the air conditioning effect and minimizing pressure loss along the way, so that multiple rooms can be heated and cooled efficiently and economically with a single air conditioner 1.
