Abstract

PURPOSE: To perform the condensing pressure control for securing a pressure differential required for the frost growth prevention of the indoor heat exchanger as well as for the oil supply to the compressor quietly and without power consumption by incorporating a superconductor two-way valve at the inlet or outlet of a condenser or in the middle of refrigerant pipes between them that is closed when the temperature drops below a specified level.
CONSTITUTION: As the superconductor valve 23 in a superconductor two-way valve 10a is made of a material which becomes superconductive below 40°C, it is repulsed by a permanent magnet 24 below 40°C to tightly close the valve, and, as the superconductor valve 23 in a superconductor two-way valve 10b is made of a material which becomes superconductive below 35°C, it is repulsed by the permanent magnet 24 to tightly close the valve. Therefore, the superconductor valve 10a is close when the condensing temperature drops below 40°C and the superconductor valve 10b below 35°C, and so, the condensing pressure control becomes possible, always ensuring a pressure differential required for the frost growth prevention of the indoor heat exchanger 5 as well as for the oil supply to the compressor 1.
