Further, FIG. 3 shows an example of a configuration having a hot water supply/cooling/heating function, and the heating heat exchange unit 13 and the outdoor unit 4 are
A unit having exactly the same configuration as the unit shown in FIG. A heat pump cycle is constructed by connecting through pipes. The configuration inside the throttle υ mechanism unit 141 includes a four-way switching valve 40 and a solenoid valve that connects three ways to independent connection valves 35, 36, and 37, and the other way to a solenoid valve 38, 39 arranged in parallel. Check valves 41.38 and 41.39 are arranged in parallel with each other.
42 and each connection valve 43.44 of solenoid valve 38゜39
and make up the gas side, and several of them are branched into three ways from the connection valve 27 and connected to gear pillar tubes 46 and 46.
The capillary tube 45 is connected to the connection valve 28 via the check valve 4, and the capillary tube 46 is connected to the connection valve 48. The heating and cooling heat exchange unit 34 includes a heat exchanger 49, a blower 50, and a gas pipe valve 6.
1. It is composed of a liquid pipe valve 52. The entire refrigerant piping configuration is completed by connecting the valves of the four units described above with refrigerant connecting piping as shown in FIG. Each operation mode in the above configuration will be explained. In the hot water supply mode, the solenoid valve 38 is opened and the solenoid valve 39 is closed, and the four-way switching valve 40 is operated so that the discharge pipe 16 of the compressor 7 vane 1 communicates with the solenoid valve 38. 16 communicates with the outdoor heat exchanger 2. Therefore, the discharge gas of the compressor 1 is depressurized with the heating heat exchanger 7 as a condenser and the capillary tube 45, and the heat source side heat exchanger 2 is used as an evaporator to form a heat pump cycle. It provides hot water function. Since the electromagnetic valve 39 is closed and the capillary tube 46 is in communication with the low pressure side, the heat exchanger 4
9 is maintained at a low pressure so that the refrigerant liquid does not accumulate.

In the case of heating mode, the solenoid valve 38 is closed, the solenoid valve 39 is opened, and the four-way switching valve 40 is set in the same manner as the hot water supply mode, so that the discharge gas of the compressor 1 is transferred to the capillary tube using the heat exchanger 49 as a condenser. The pressure is reduced at 46, forming a heat pump cycle as a heat source side heat exchanger, and heating is performed by blowing out hot air at a heat exchanger 49. When the electromagnetic valve 38 is closed, the capillary tube 45 is communicated with the low pressure side, so the heating heat exchanger 7 is maintained at a low pressure and no refrigerant liquid accumulates.

In the cooling mode, the suction pipe 16 is communicated with the solenoid valves 38 and 39 by operating the four-way switching valve 40 so that the discharge pipe 15 of the compressor 1 communicates with the gas pipe of the heat source side heat exchanger 2. Solenoid valves 38 and 39 are closed. Therefore compressor 2
is used as a condenser, the pressure is reduced by the capillary tube 46, and the heat exchanger 49 is used as an evaporator for cooling, and the reverse tl = valve 42
and is sucked into the compressor 1. At this time, check valve 47
Since the flow to the heating heat exchanger 7 is blocked and the check valve 41 is communicated with the low pressure, the heating heat exchanger 7 is maintained at a low pressure and there is no accumulation of refrigerant liquid.

As explained in the embodiment shown in FIGS. 2 and 3 above, the discharge pipe 16 and suction pipe 16 of the compressor 1 and the gas pipe 17 and liquid pipe 18 of the heat source side heat exchanger 2 are each independently separated and valved. 19.2
The outdoor unit 4 and the heating heat exchanger unit 1 are configured to be taken out to the outside of the unit via 0.21 and 22.
By dividing the outdoor unit 4 and the heating heat exchanger unit 13 into three units: 3 and the throttle mechanism unit 14 or 14' configured according to the function, the outdoor unit 4 and the heating heat exchanger unit 13 have only one standard specification, and the throttle mechanism unit 14 can function. It only takes 9 pages to configure the unit according to the requirements, and you can freely add the necessary functions, so there is no need to create an outdoor unit for each function as in the past. In this case, it has a great effect that necessary functions can be easily added just by replacing the aperture mechanism unit.
