Description

[Detailed Description of the Invention] The present invention relates to a multi-type heat pump type air conditioner/heater, and aims to make the functions of such a heat pump type air conditioner/heater multi-purpose and wide-ranging in use to suit the installation conditions of the consumer side. Conventionally, multi-type heat pump type air conditioners, which connect multiple indoor units to one outdoor unit, have become popular in the market in recent years, and are used primarily for heating, cooling, and air conditioning in general households. ing.

However, these multi-type heat pumps 2/2
・For example, when a 1:2 multi-type heat pump type air conditioner is installed for the purpose of heating and cooling two rooms, it functions only as an air conditioner in that room and does not perform any other functions. The diverse demands of the people have not been answered.

Therefore, if you want to get a water heater, you have to install another heat source.

The present invention focuses on these points and provides a multi-purpose heat pump air conditioner, and one embodiment thereof will be described below with reference to FIGS. 1 to 4. 1 is an outdoor unit, and 2 is a main indoor unit that performs cooling and heating. Reference numeral 3 denotes a device to which other devices are connected, such as the hot air fan 4, dryer 5, water heater 6, etc. shown in FIG. 7 is a compressor, 8 is a four-way valve, 9 is a first solenoid valve, 10 is an outdoor heat exchanger,
11 is a check valve provided in the flow direction during cooling; 12 is a check valve provided in the flow direction during cooling;
A capillary archive provided at a position bypassing the check valve 11; 13, a cooling capillary; 14, an indoor heat exchanger; 15, a blower; 16, a second solenoid valve; 17, an accumulator; and 18, 3 19 is a fourth solenoid valve, 20 is a capillary tube, and 21 is a high-pressure pressure regulating valve, which is connected from the discharge pipe 22 to the piping 23 and the heat exchange section 24, and further connected to the suction pipe 25. ing. 26 is an injection tube, and a capillary tube 2γ is provided in the middle. 28 is a fifth solenoid valve for power saving, one end of which is connected to the injection pipe 2.
6, the other end is connected to the suction pipe 26. 29,30
31.32 is the connection port of the outdoor unit 1, 33.34 is the connection port of the indoor unit 2, 35.36 is the connection port of the device 3 side, and in the device 3, for example, the hot air heater 4 is connected to the refrigerant pipe 3.
7. Heat exchanger 39° connected to 38 Air blower 40
．． It has connection ports 41 and 42.

The dryer 5 has a blower 43 and a heat exchanger (heater) 44 below.
, has connection ports 45 and 46. The water heater 6 is surrounded by a heat insulating material 47, and has a water supply port 48, a hot water supply port 49, a heat exchanger (heater) 5o, and a connection port 51 that connects to the refrigerant crystal tube 37, 38.
．． 52.

In the above configuration, the outdoor unit 1 and the indoor unit 2
will be connected from the beginning for heating and cooling purposes. or,
At the other connection port 31.32, for example, the water heater 6
Suppose you connect to In this construction, during cooling, the compressor 7, the third solenoid valve 18, the heat exchanger 50 of the water heater 6, the fourth
The circuit includes the solenoid valve 19, capillary tube 20, capillary tube 13, indoor heat exchanger 14, second solenoid valve 16, four-way valve 8, and compressor 7, and the heat exchanger 50 of the water heater 6 utilizes condensation heat. While supplying hot water, the indoor heat exchanger 1
4 for cooling. Next, during the same cooling period, when hot water supply is not required, the compressor 7, four-way valve 8, first solenoid valve 9, outdoor heat exchanger 10, check valve 11, capillary tube 13, indoor heat exchanger 14, It operates with a standard circuit consisting of the second solenoid valve 16, four-way valve 8, and compressor 7 to perform cooling.

Next, during heating, the equipment 3 is replaced by the warm air fan 4 shown in FIG.
Either the dryer 5 in FIG. 3 or the water heater 6 in FIG. 4 may be connected and combined.

For example, if dryer 5 is connected, compressor 7, third
Solenoid valve 18, dryer 5, fourth solenoid valve 19, capillary tube 20. It consists of 12.6 capillary tubes, an outdoor heat exchanger 1o, a first solenoid valve 9, a four-way valve 8, and a compressor 7 circuit, and the dryer 5 dries the material. Also, when performing heating in the indoor unit 2, when the fourth solenoid valve 19 is closed and the second solenoid valve 16 is opened, the compressor 7, four-way valve 8, second solenoid valve 16, indoor heat exchanger 14, Capillary tubes 13, 12, outdoor heat exchanger 10. The circuit includes the first solenoid valve 9, the four-way valve 8, and the compressor 7, and the indoor unit 2 performs heating. Therefore, when the indoor unit 2 is used primarily for heating, either the heating or the equipment 3 is selected.

As described above, the present invention provides the functions of a multi-type heat pump type air conditioner by connecting one or more indoor units mainly for air conditioning, heating and air conditioning on the one hand, and a hot air fan and a dryer on the other hand.

It is a multi-type heat pump type air conditioner/heater with a refrigerant circuit that can be used even when a water heater, etc. can be connected at a later date, or even when connected to the main indoor unit at the same time. ,budget.

641. - It is convenient because it allows you to connect any device depending on the housing conditions, making it multipurpose and responding to a variety of requests.

Furthermore, since it is not necessary to use other heat source equipment, it is effective in saving resources.
