Document Type and Number:
Japanese Patent JP4463466
Kind Code:
B2
Abstract:
In an ejector cycle system, hot gas refrigerant discharged from a compressor (100) is introduced into an evaporator (300) through a bypass passage (700) while bypassing an ejector (400) and a gas-liquid separator (500) in a defrosting operation for defrosting frost generated on the evaporator. In addition, a throttle (520) or a check valve (510) is provided in a refrigerant passage (L1) from the gas-liquid separator to a refrigerant inlet side of the evaporator. Accordingly, in the defrosting operation, the hot gas refrigerant from the compressor can be accurately introduced into the evaporator through the bypass passage without flowing toward the gas-liquid separator.
