Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential air conditioning system capable of simultaneously performing air conditioning on a plurality of rooms of a general house.

[0002]

2. Description of the Related Art Conventionally, when it is desired to air-condition an entire main room of a building such as a bedroom, a child room, a living room, etc., in an ordinary house, an air conditioner is generally provided for each room. . However, when deploying an air conditioner in each room, it is necessary to secure a space for installing the indoor unit in each room, and the number of outdoor units installed outdoors is also increased. There is also a concern that the aesthetics of will be damaged. Therefore, in recent years, with the improvement of functions such as heat insulating materials and sealing materials and the application of heat insulating glass to building materials, etc. There is an idea to adopt a so-called central type air conditioning system similar to buildings and the like. According to this central type air conditioning system, a heat source device, an air conditioner, etc. are provided in one room in the house (hereinafter referred to as a machine room), and centralized management is performed here to create the conditioned air Since it is sent to each room by the air multi system, there is an advantage that it is no longer necessary to provide an indoor unit in each room.

[0003]

However, if the above conventional central type air conditioning system is adopted as it is in a normal house, the harmony created in the machine room is between the machine room and each room. A blow-out duct for sending air into the room and a suction duct for taking in the unconditioned air in the room and returning it to the machine room must be provided, which causes the following inconvenience. That is, if the duct crawls under the ceiling, the living space will be compressed and the aesthetics of the room will be impaired. On the other hand, the problem of indoor air pollution is becoming more serious as housing becomes more airtight.

The present invention has been made in view of the above circumstances and provides a residential air conditioning system capable of simultaneously performing air conditioning and air purification on a plurality of rooms with an inexpensive and simple structure. It is intended to be provided.

[0005]

In order to solve the above-mentioned problems, the invention according to claim 1 has the above by an air conditioner having an outdoor unit and an indoor unit installed at a certain place in a house. An air conditioning system for performing air conditioning of any of a plurality of rooms adjacent to a location, wherein each room has conditioned air blown from the indoor unit directly or via the location. An air inlet, an anharmonic air outlet for returning a part of the indoor air to the indoor unit directly or via the certain point, and an exhaust means for discharging a part of the indoor air to the outside. Provided, in addition,
An operation unit for a person to set the air conditioning condition in the room is provided, and the air conditioner drives the exhaust unit provided in the corresponding chamber according to the operation of the operation unit by the person. It is characterized in that a control unit for controlling the air conditioning of the corresponding room is provided while controlling the air conditioning.

[0006]

According to the air conditioning system of the first aspect, it is possible to simultaneously perform air conditioning for a plurality of rooms with a cheap and simple structure. In addition, since the air circulation path is formed by the ventilation means, it is possible to avoid contamination of indoor air, which tends to be a problem in a highly airtight and highly insulated house.

This second-floor portion has a staircase 1, a bedroom 2, and an adjacent room which is partitioned from the bedroom 2 by a partition wall 3. The child room 4 and the child room 6 which is an adjacent room partitioned by a partition wall 5 are roughly configured.

At the end of the staircase 1 at the end of the corridor (not shown) and in the vicinity thereof, the entrances and exits of each room (bedroom 2, children's rooms 4, 6) are gathered together.
Doors 9, 10 having lower air vents (slit-shaped openings with blades attached in parallel) 7, 8, ...
11 is attached. These doors 9, 10, 11
On the small wall directly above, the upper part for ventilation is exposed 12,13,1
4 are provided. These upper parts are 12, 13, 1
An indoor unit 15 of the air-conditioning apparatus applied to this example is installed in a ceiling portion sandwiched by 4 with the outlet of conditioned air and the inlet of non-conditioned air directed downward. Furthermore, on the outer wall of each room 2, 4, 6
Ventilation fans 16, 17, 18 for exhausting non-conditioned air are attached.

Next, the electrical configuration of the air conditioning system of this example will be described with reference to FIG. The outdoor unit 19 includes a compressor that compresses the refrigerant, a condenser that liquefies or vaporizes the refrigerant, a fan, a fan motor, and the like, and is installed, for example, on a veranda (not shown). The indoor unit 15 includes a cooler, an indoor fan, a fan motor, a filter, and the like, and cools or warms the air by the refrigerant sent from the outdoor unit 19 to create conditioned air. In this example, the indoor unit 15 is adapted to take in the outside air via the outdoor unit 19, and the taken-in outside air and the anharmonic air collected from the indoor side are mixed to produce conditioned air.

The control unit 20 includes a CPU (central processing unit),
It is composed of memories such as ROM and RAM and an interface, and is housed in the housing of the indoor unit 15. Control unit 2
When the CPU constituting 0 is supplied with operation start / stop signals, cooling / heating signals, temperature setting signals, air volume setting signals, etc. from the operation panels 21, 22, 23 provided in the respective rooms 2, 4, 6. By executing the processing program stored in the ROM using the RAM, the respective units of the indoor unit 15 and the outdoor unit 19 are controlled, and the ventilation fans 16, 1 are provided.
7 and 18 are controlled. The above processing program is the indoor unit 1
5, the outdoor unit 19 and the ventilation fan 16 are created based on a predetermined algorithm in order to efficiently perform the air conditioning operation in the optimum cooperative relationship.

On / off and strength of the ventilation fans 16, 17, and 18 are basically controlled by the control unit 20, and conditioned air is made to flow into the room by the operation. Operation panel 2
Reference numerals 1, 22 and 23 are composed of a power switch, a mode setting switch, an adjusting key, a temperature sensor, an infrared receiver, etc., and are attached to the wall surfaces of the rooms 2, 4, and 6. The power switch is for starting or stopping the operation of the air conditioning system, the setting switch is for setting the cooling mode, the heating mode or the air blowing mode, and the adjustment key is for adjusting the room temperature and the air volume. Are used respectively. The temperature sensor detects the room temperature and sends the detection result to the control unit 20. Remote controls 21a, 22a,
The reference numeral 23a is used when remotely controlling on / off of the power switch, mode setting, room temperature control, etc., and includes a power switch, a mode setting switch, an adjusting key, a temperature sensor, an infrared transmitter, and the like. . And
Various information input from the remote controllers 21a, 22a, 23a is transmitted from the infrared transmitting section to the infrared receiving sections of the operation panels 21, 22, 23, and finally supplied to the control section 20.

Next, the operation of the air conditioning system of this example will be described. For example, to describe the case where all the rooms 2, 4, 6 are warmed in the winter, first, each person in the room operates the operation panels 21, 22, 23 or the remote controller 21a ,.
22a and 23a are operated to depress the power switch, select the heating mode, and further input the desired temperature and air volume. Each operation panel 21, 22, 23,
The control unit 2 generates an operation start signal, a heating signal, a set temperature signal, a set air volume signal, etc. based on the input contents of the person in the room.
Supply to 0. The CPU of the control unit 20 is the operation panel 2
When various signals are supplied from 1, 22, 23, power is supplied to each part of the system, the indoor unit 15 and the outdoor unit 19 are operated in the heating mode, and the ventilation fans 16, 17, 18 are operated. As a result, the conditioned air is extracted from the air outlet in the peripheral portion of the lower surface of the indoor unit 15, while the non-conditioned air is sucked from the suction opening in the central portion of the lower surface. In addition, each ventilation fan 16, 17, 18 starts operating in an operating state according to the setting conditions such as temperature and air volume in each room.

When the ventilation fans 16, 17, 18 are operated, the air in each of the chambers 2, 4, 6 is discharged to the outside, and as a result, the inside of each of the chambers 2, 4, 6 is in a negative pressure state. Therefore, the indoor unit 15
Warm and light conditioned air blown out from the roof
It flows into each of the chambers 2, 4 and 6 via 2, 13 and 14 (see FIGS. 2 and 3). The ventilation fans 16, 17, 18
Operates only in the exhaust direction, so cold air outside does not flow into the room. On the other hand, since the air immediately below the indoor unit 15 (corridor abutment portion) is sucked in from the suction port of the indoor unit 15, an ascending air current is generated at the abutment portion of the corridor, and as a result, a negative pressure is generated in the lower portion of the abutment portion of the corridor. Therefore, each room 2, 4, 6 is routed through the lower parts 7, 8 ,.
The non-harmonic air inside is discharged to the corridor side and becomes an updraft and is sucked into the suction port of the indoor unit 15 (see FIG. 3). In this example, the amount of conditioned air blown out from the indoor unit 15 is the sum of the amount of anharmonic air discharged from the ventilation fans 16, 17, and 18 and the amount of anharmonic air sucked by the indoor unit 15. It is controlled so that they are substantially equal. Thus, the air conditioning of all the rooms 2, 4, 6 is performed.

After that, for example, when the air conditioning of the child rooms 4 and 6 is no longer desired, the operation panels 22 and 23 or the remote controllers 22a and 23a are operated to depress the power switch. The operation panels 22 and 23 generate an operation stop signal and supply it to the control unit 20 when the power switch of their own or the remote controllers 22a and 23a is pressed. When the CPU of the control unit 20 receives the supply of the operation stop signal, the CPU of the control unit 20 stops the operation of the corresponding ventilation fans 17 and 18. When the operation of the ventilation fans 17 and 18 is stopped, a large pressure difference does not occur between both sides of the upper louvers 13 and 14, so that the warm and light conditioned air blown out from the indoor unit 15 almost flows into the child rooms 4 and 6. do not do. Thus, only bedroom 2 is air conditioned.

On the other hand, in the summer, the cooling mode should be set. As a result, the CPU of the control unit 20
Controls the refrigerant flowing between the outdoor unit 19 and the indoor unit 15 so as to flow in the opposite direction to the winter season, and
Switch between the air outlet and the air inlet. That is, the conditioned air is extracted from the central portion of the lower surface, while the anharmonic air is sucked from the peripheral portion of the lower surface. Thus, the cold and heavy conditioned air blown out from the air outlet at the center of the lower surface of the indoor unit 15 descends and flows into the respective chambers 2, 4, 6 from the lower slops 7, 8 ,. On the other hand, the warm non-harmonic air in each room 2, 4, 6 is sucked into the suction port of the indoor unit 15 via the upper burrs 12, 13, 14. In addition, ventilation fan 1
Since 6, 17 and 18 operate only in the exhaust direction, warm air outdoors does not flow into the room.

According to the above structure, it is possible to simultaneously perform air conditioning on a plurality of chambers at a low cost and with a simple structure. In addition, since the air circulation path is formed by the ventilation fan, it is possible to avoid contamination of indoor air even in a highly airtight and highly heat-insulated house.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, ventilation fan 1
6, 17, 18 may be manually turned on / off as appropriate, or only the ventilation fans 16, 17, 18 may be operated. Glass 7, 8, ..., 12, 13,
The installation position of ... is not limited to a small wall or a door. Further, movable blades may be used for the blades of the galleries 7, 8, ..., 12, 13 ,.

Further, as a modification of the above-mentioned embodiment, the movable blades of the electric type make it possible to use the louvers 7, 8, ..., 12, 13,
If the control unit 20 can control the direction of the movable blades, the louvers 7, 8, ..., 12, 13, ... of the chamber where air conditioning control is not desired can be automatically closed. Therefore, the air conditioning control for each room can be performed more reliably.

Further, in the above-described embodiment, the conditioned air is once blown out from the indoor unit 15 to a place (the end of the corridor) where the staircase 1 is located, and the galleries 7, 8 ,.
Although the configuration in which each of the chambers 2, 4, and 6 is taken in via the chambers 2, 13, ... has been described, instead of this, for example, FIG.
The conditioned air may be sent directly to the bedroom 2 by providing the wind guide wall 24 as shown in FIG.

[0020]

As described above, according to the air conditioning system of the present invention, air conditioning can be simultaneously performed for a plurality of rooms with a cheap and simple structure. in addition,
Since a part of the air circulation path is formed by the ventilation fan, it is possible to avoid contamination of indoor air, which tends to be a problem in a highly airtight and highly insulated house.
