<P>PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of extending the duration of cooling. <P>SOLUTION: The refrigeration cycle device, in which a compressor 10, a condenser 20, an expander 30 and an evaporator 40 are sequentially connected in a loop by a refrigerant flow path 50, includes: a fluid reservoir 70 which is provided on a downstream side of the evaporator 40 and can store the refrigerant to supply it to the evaporator 40; a liquid refrigerant sensor 102 for detecting a liquid refrigerant amount stored in the fluid reservoir 70; a refrigerant flow path on-off valve 60 for opening/closing the refrigerant flow path 50 between the expander 30 and the evaporator 40; and an air conditioning control circuit 100 which opens the refrigerant flow path on-off valve 60 when the compressor 10 is driven, and closes the refrigerant flow path on-off valve 60 based on detection of the liquid refrigerant sensor 102 when the compressor 10 is stopped. <P>COPYRIGHT: (C)2012,JPO&INPIT |
