Abstract

PURPOSE: To make electric power for heating unnecessary and prevent freezing economically by a method wherein a capillary tube is provided at least in either one of a drain hose, a drain case and an expansion valve while the capillary tube, into which high-temperature freezing machine oil flows, is used as a heater.
CONSTITUTION: High-temperature freezing machine oil, discharged out of a compressor 1 after being mixed with refrigerant, is separated in an oil separater 2, is sent to the outlet port of an accumulator 7 through a capillary tube 10 and is returned to the compressor 1 again after being mixed with the refrigerant again. The freezing machine oil keeps a high temperature after flowing into the capillary tube 10 and heats a drain hose 9 or a drain case 8, in which the capillary tube 10 is provided.
