SME alloys are made of nickel, titanium alloys, copper, zinc, aluminum alloys, etc., and have the property of restoring a memorized shape by heating or cooling. Now, the second
Coil L of length l made of SME alloy shown in Figure A
Suppose that stores the length l 1 (l=l 1 ). When this is stretched to a length l 3 at a certain temperature A and heated (l=l 3 ), when a certain temperature B is exceeded, it returns to the initially memorized length C. When heating is stopped and the temperature drops to a certain temperature D, it begins to elongate, and when l = l 2 , it is heated again to E, and when it reaches temperature F (same temperature as B), it returns to the length l 1 again C. . The diaphragm 12 of the present invention is made of the above-mentioned SME alloy, and as shown in FIG. One capillary tube 14 of the thermosensitive element 13 is fixed to one capillary tube 16 of the case 18, the other capillary tube 15 is slidably inserted into the other capillary tube 17, and the controller 19 is housed inside the case 18. heater 20 controlled by
It has a structure with 21 is a power source for the heater 20, and 22 is a refrigerant pipe.

The operation of the present invention will be explained. The refrigerant compressed by the compressor 4 is condensed in the outdoor heat exchanger 5, and then transferred to the distributor 10.
a, 10b, and 10c to indoor unit 2.
a, 2b, 2c, enter capillary tube 7
The pressure is reduced in a, 7b, and 7c, and the indoor heat exchanger 8a,
It evaporates at 8b and 8c and returns to the compressor 4. For the distributors 10a, 10b, and 10c, among the plurality of indoor units (three), only the distributor of the indoor unit that is used opens the on-off valve, and the distributor of the indoor unit that is not used opens the on-off valve. Closed.

に上昇するなどの問題を生ずる。 By the way, in this type of device, the capacity of the outdoor unit 1 is divided into a plurality of indoor units 2a, 2.
Since the total is calculated according to the total capacity of b and 2c, one or two of the three indoor units
When the stand is at rest, the restrictor 12 is connected in parallel with the on-off valve 11.
In conventional devices of this type that do not have a refrigeration system, all the compressed refrigerant concentrates in the capillary tube 7 of the indoor unit used, which upsets the balance of the capacity of the refrigeration cycle, causing the system as a whole to become over-throttled, resulting in As a result, the evaporation pressure of the indoor heat exchanger 8 that is used decreases, causing a frosting phenomenon, and the compressor 4 causes problems such as an increase in the temperature of the low-pressure refrigerant taken in, and an abnormally high discharge temperature.

動作するようにすればよい。 In contrast, in the present invention, each distributor 10 has a restrictor 12 in parallel with the on-off valve 11, so even if the on-off valve 11 of the indoor unit 2 that is not used is closed, the restrictor 12 will reduce the pressure to an appropriate degree, so the system Reduces overall over-squeezing. In other words, the wringer 1 of the present invention
2, the length l 1 shown in FIG. 2 is stored in the thermosensitive element 13 at a certain temperature, and this is plastically worked to a length l 3 and heated by the heater 20, as shown in FIG. 2. It expands and contracts like this. FIG. 3A shows the case where the length of the thermosensitive element 13 is l 1 and B shows the case when the length is l 3 .
As is clear from the figure, the refrigerant capillary passage l4 in A is longer than the capillary passage l3 in B, and it can be seen that the passage resistance of the refrigerant in A is greater than in B. The expansion and contraction of the thermosensitive element 13 is controlled by controlling the temperature of the heater 20 by a controller 19. The controller 19 may be operated by a signal from a temperature sensor provided near the refrigerant outlet of the indoor heat exchanger 8, for example.

As a result, the aperture of the entire system can be appropriately adjusted, thereby solving the above-mentioned problem. In addition, the SNE alloy has excellent properties such that its thermal deformation can be easily controlled and ensures reliable operation of the wringer 12 of the present invention.
