Abstract

PURPOSE: To operate defrosting speedily, by drawing the refrigerant condensed in the heat exchanger immediately into another heat exchanger at the time of defrosting the heat exchanger.
CONSTITUTION: The high-temperature, high-pressure refrigerant ejected from compressor 1 flows into heat exchanger 12 via three-direction valve 9 as shown by the dotted line. While melting the attached frost, it becomes liquid refrigerant. Since the side opposite to check valve 10 and expansion valve 8 is connected to the side of receiver 7 and is under high pressure, the liquid refrigerant flows into heat exchanger 16' via No. 2 decompression device 15. Here it obtains heat from the atmosphere and returns to compressor 1 via three-direction valve 9' and four-direction valve 11 and recycles. In this way, since the refrigerant condensed in a heat exchanger at the time of defrosting the heat exchanger is drawn into another low- pressure heat exchanger immediately, defrosting can be operated speedily.
