Reducing pressure by regulating flow effect less it is ensured that from control valve 5 flow out refrigerant and from outdoor heat exchanger 3 flow out refrigerant between the temperature difference relatively
Little.
As shown in the solid arrow in Fig. 1, the refrigerant discharged from the exhaust outlet a of compressor 1 passes through first port c and second
Port d flows into outdoor heat exchanger 3 and is condensed, and the refrigerant discharged from outdoor heat exchanger 3 enters into unidirectional section by the first valve port m
In stream valve 7, the now fully on effect playing connecting tube of one-way throttle valve 7, the refrigerant flowing out from the second valve port n is divided into two
Point, a portion refrigerant is flowed in restricting element 8 by the second refrigerant flow 10 and carries out reducing pressure by regulating flow, another part refrigerant
It is flowed in radiating subassembly 61 by control valve 5 and electric control element 60 is radiated, the refrigerant flowing out from radiating subassembly 61 flows into
