Description

Description: FIELD OF THE INVENTION The present invention relates to an air conditioning system in a house.

2. Description of the Related Art In a conventional air conditioning system for a house, a floor-standing or wall-mounted indoor unit is installed in each room, or a plurality of indoor units are installed as a separate air conditioner for one outdoor unit. The main thing is to install each. Providing an indoor unit for each room in the former requires an outdoor unit for each room, and in the latter, a plurality of indoor units are connected to one outdoor unit in a refrigerant arrangement. Further, there is a window type as another air conditioner, but this is also an air conditioner for each room. Furthermore, an outdoor water cooler and a boiler are provided as heat sources, pipes are installed in each room to connect with a terminal (radiator) provided in each room, and cold and hot water is passed through the air conditioner. Some do.

Problems to be Solved by the Invention As described above, in the case where the number of outdoor units and the number of indoor units are set up, the initial cost increases in a house having a large number of indoors. On the other hand, in the so-called multi-type in which one outdoor unit has two to three indoor units, the initial cost is cheaper than the former, but only two to three rooms remain, and the other rooms are completely air-conditioned. There is no such thing. In addition, since the window type air conditioner is provided for each window in the room, the initial cost is high and the appearance is not good. Further, a central central system having a heat source for a water cooler and a boiler has a significantly high initial cost, which is not common.

In short, there are various types of air-conditioning systems at present, and they have advantages and disadvantages, and the air-conditioning system suitable for the house is not satisfactory for the user side.In particular, the air-conditioning up to a small space in the house is especially considered. However, for example, air conditioning in small spaces such as detachable clothes, washrooms, toilets, etc. tends to be ignored, including air conditioning in kitchens where exhaust fumes for kitchens are becoming an essential requirement. There was a problem that

The present invention solves these problems, and unlike an air conditioning system in which the outdoor unit and the indoor unit are one-to-one or a central central system, it is relatively inexpensive and can perform air conditioning to a small space. The purpose is to provide a system.

Means for Solving the Problems In order to solve this problem, the present invention comprises one outdoor unit and an indoor unit provided in each main living room and connected by a refrigerant pipe, Each indoor unit is equipped with a small blower that sucks in the air in the room, and this small blower is connected to the air outlet provided in a necessary small space such as a dressing room, toilet, kitchen, etc. with a duct, and the duct is optional. The system has a damper that opens and closes.

Operation With this configuration, the indoor unit provided in the main room will be air-conditioned, and when it is desired to air-condition a small space such as a kitchen or a dressing room, the small blower installed in the indoor unit will be operated.
The damper provided in the duct is communicated with the side of the small space that requires it, and the air in the room is blown to the small space.

In FIG. 1, reference numeral 1 is a single house, which is located on the north side of the first Japanese-style room 2 and the second Japanese-style room 3 and is provided with a curtain 4 or a bing room 5, a kitchen 6 and a front door 7, and this front door 7 The floor plan includes a washroom 8, a bathroom 9, a dressing room 10 and a toilet 11, which are located in a high place. An outdoor unit 12 equipped with a compressor equipped with an inverter and an outdoor heat exchanger (neither is shown) is installed on the outside of the house 1, and the outdoor unit 12 includes refrigerant pipes 13, 15,
Main unit No. 1 installed in the first Japanese room 2 by 17
And a main indoor unit No. 16 installed in the second Japanese-style room 3,
It is connected to the third indoor unit 18 installed in the living room 5.

As will be described with reference to FIG. 2 and FIG. 3, the above-described indoor unit No. 1 to indoor unit Nos. 14, 16 and 18 are located in front of the air intake port in order to circulate the air in the room and perform cooling and heating. 19 and a blower outlet 20 located on the lower side, and a side blower chamber 21 is provided with a small intake port 22 for sucking the air in the room and a small blower 23, and the small blower 23 is upward. It is connected to the communicating duct 24. The duct 24 is attached to the ceiling surface 2 along a part of the wall surface 25 in the room.
It penetrates 6 and is arrange | positioned to the position required suitably.

That is, in FIG. 1, the first indoor unit 14 is connected to a distributor 27 by a duct A, and a damper 28 for switching between a duct B side and a duct C side by a damper motor is provided in the distributor 27. There is. The damper B is connected to the air outlet 29 of the toilet 11, and the damper C is connected to the air outlet 30 of the removable clothing room 10. On the other hand, the main indoor unit No. 2 16 installed in the second Japanese-style room 3 is connected to the distributor 31 by the duct D, and this distributor 31 is provided with a damper 32 for switching between communication with the duct E side or communication with the duct F side. The duct E is connected to the air outlet 33 provided in the space inside the entrance 7, and the duct E is connected to the air outlet 34 provided in the washroom 8. On the other hand, the main indoor unit No. 3 18 installed in the living room 5 is connected to the distributor 35 from the duct G, and a damper 36 is provided in the distributor 35 to communicate with the duct H side or the duct J side. And the duct H is switched to each other, and the duct H is connected to the outlet 37 provided in the kitchen 6 and the duct J.
Is connected to an outlet 38 that locally blows out a place where a dressing table or the like is placed. A dryer 39 is provided in the ceiling of the bathroom 9, and the dryer 39 is connected to the outdoor unit 12 by a refrigerant pipe 40.

In the above-mentioned structure, the second Japanese-style room 3 including the first Japanese-style room 2 and the living room 5 have their respective refrigerant pipes 13 and 1.
5 and 17 are connected, and the remote control switch (not shown) provided in each room is operated to
~ Air conditioning is performed by Unit 3 18 in the main room. Here, the outdoor unit 12 is controlled by a compressor controlled by an inverter in accordance with the variation of the indoor load, so that the outdoor unit 12 generally outputs a sufficient air conditioning capacity. Therefore, if, for example, in a space other than such a main room, which is used for a small amount, for example, in the washroom 8 for about 30 minutes, a blow port 34 is used.
By operating a remote control switch (not shown) provided on the wall near the unit, the main unit No. 2 16 in the main unit is operated from the outdoor unit 12, and the small blower 23 shown in FIG. The damper 32 of 31 is connected to the duct F side. Then, the air in the second Japanese-style room 3 that has begun to be air-conditioned or the air in the second Japanese-style room that has already been air-conditioned in the second Japanese-style room 3 is made to flow in from the small intake port 22 and via the distributor 31 via the small blower 23. Duct F
The air is blown out through the air outlet 34 and is used for air conditioning for small use in the washroom 8. Similarly, when responding to a visitor at the entrance 7, a remote control switch (not shown) provided at the entrance is operated to switch the damper 32 to the duct E side so that the conditioned air corresponding to the visitor is supplied from the outlet 33. Blow out. More specifically, since the kitchen 6 uses the ventilation fan 45, the air conditioning load of the kitchen is relatively large. Therefore, it is necessary to provide air conditioning for the cooking time of about 2 hours. At that time, the remote control switch (not shown) provided on the wall of the kitchen 6 is operated to drive the third indoor unit 18 from the outdoor unit 12, or in the state where the living room 5 is already operating. While operating the small blower 23, the damper 36 of the distributor 35 is switched to the duct H side. In this way, the small blower 23 is operated while operating the third unit 18 in the main room, and the air conditioning of the kitchen 6 is performed from the duct G through the duct H and the outlet 37. However, at this time, if the air conditioning load in the living room 5 is also used in many other rooms,
Although the sufficient air-conditioning capacity is not output, it is ignored during the cooking time and the output of the living room 5 is reduced while the kitchen 6 is the main output. So when the cooking time is over,
The small blower 23 is stopped so that the air is returned to the air conditioning of the living room 5.

The same applies to the blowout port 38, and also in the toilet 11 and the putting on and taking off clothes room 10 as well as the operation of the first indoor unit 14 (by the remote control switch), the small blower 23 provided in the first indoor unit 14 is installed. It is operated and operated by a remote control switch (not shown) provided in the vicinity of each of the air outlets 29 and 30, and is used for air conditioning of a small space such as the toilet 11 and the detachable clothing room 10. Further, since the dryer 39 is provided in the bathroom 9 and is connected to the outdoor unit 12 by the refrigerant pipe 40, in the winter, warm air is blown from the dryer 39 by the heat pump operation to dry the laundry in the bathroom 9. To do.

The point is that the main indoor unit is installed in the small space closest to the installed position via a distributor with a damper, or without a distributor, the duct is directly installed in the small space and the space between the houses It provides air conditioning to the small space corresponding to the space.

The duct connected to the outlet from each main indoor unit to the small space was equipped with a distributor when there were multiple outlets and switched by a damper.However, when connecting directly to the outlet, a small blower A damper may be provided on the outlet side.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, the present invention includes one outdoor unit provided outside the house and an indoor unit provided in each main living room and connected by a refrigerant pipe. And a duct system in which each of the indoor units is provided with a small blower for sucking in the air in the room, and the small blower is connected to an outlet provided in a small space by a duct, and a damper for arbitrarily opening and closing the duct is provided. Therefore, the air conditioning for small use in the small space can be easily performed in the freely designed floor plan, and the air conditioning of the small space including the main living room of the house becomes possible. Also, since it is sufficient to air-condition the main living room with one outdoor unit and the number of main indoor units, add a small blower, and perform duct-related work, compare it to installing each main living room individually. Even if compared with the central system, the initial cost can be reduced.
