ければならず、コストの上昇を招くという欠点がある。By the way, in such an air system, four temperature detectors are required to detect the degree of superheating during cooling operation and the degree of superheating during heating operation. The drawback is that there are too many. In addition, since the temperature detector is divided into outdoor unit (A) and indoor unit (B), there is a drawback that the control gl becomes multiple. During heating operation, the piping to which the temperature sensor 12 is attached is on the heavy pressure side, so the temperature sensor 14. has to be used, which has the disadvantage of increasing costs.

゛８は室内熱交換器７から流出する冷媒温度に等しい。During cooling operation, the gas refrigerant discharged from the compressor 1 is condensed or liquefied by removing heat in the indoor heat exchanger 3. This liquid refrigerant is reduced in pressure by the T-type expansion valve 5 to a pressure at which it can easily vaporize, and is supplied to the indoor heat exchanger 7, where it is evaporated and vaporized by taking away heat. Then, this gas refrigerant is sucked into the compressor 1 through the four-way pipe P2. In addition, a part of the liquid refrigerant is decompressed in the liquid bypass circuit Vii 70'L and is sucked into the compressor 1 through the capillary tube 60. Therefore, the temperature detected by the second temperature sensor 52a in the liquid binoculars circuit 70 is approximately equal to the temperature of the refrigerant flowing into the indoor heat exchanger 7 via the electric expansion valve 5, and the first temperature in the suction line Detection temperature 1 of detector 51
8 is equal to the temperature of the refrigerant flowing out from the indoor heat exchanger 7.

The opening degree fr iii of the magnetic expansion valve 5 is controlled based on the detected superheat degree ΔT.

基づいてｉｌ（動式膨張弁５の開度を制御する。During heating operation, the waste refrigerant discharged from the compressor 1 is deprived of heat by the indoor heat exchanger 7 and condenses, that is, liquefies. This liquid refrigerant is decompressed by the magnetic expansion valve 5 to a pressure at which it can easily vaporize, and is supplied to the external heat exchanger 3, where it is evaporated and vaporized by removing heat therefrom. In this case, the liquid flowing through the electric expansion valve 5 does not flow to the liquid Pinoyasu circuit 70 because the positive pressure is low. The gas refrigerant vaporized in the outdoor heat exchanger 3 passes through the four-way valve 2 and is sucked into the compressor 1. Therefore, the detected temperature T2 of the second temperature sensor 52b is the temperature of the refrigerant flowing into the indoor heat exchanger 3. f) A Im two,
``Furthermore, the temperature Ts detected by the first temperature sensor 51 in the suction line is equal to the temperature of the refrigerant flowing out from the outdoor heat exchanger 3. Therefore, the out-of-town tti control circuit board 20 is
Overheating is detected by reducing the detection temperature aAUT5 of the first temperature sensor 51 to the detection temperature T2 of the second temperature sensor 52b (rs-T2), and based on the degree of superheating ΔT. il (controls the opening degree of the dynamic expansion valve 5).

なうことができ、制御の簡略化が回能となる。In this way, it is possible to detect overheating during cooling and heating operations while using three temperature detectors, one less than the conventional method. Since the is not on the ~j pressure side, inexpensive thermostats such as thermistors can be used for each temperature sensor, resulting in a significant cost reduction. Since it exists in A, '1u1 dynamic expansion QjE
The control performed by the valve 5 can be centrally carried out by the outdoor control circuit board 20, and the control can be simplified.
