Abstract:
A refrigeration cycle apparatus comprising:a refrigerant compressor driven in rotation by an internal combustion engine so as to compress the refrigerant,a refrigerant evaporator for performing heat exchange with air on the inflowing refrigerant to cause it to evaporate and vaporize,a refrigerant circulation circuit for circulating the refrigerant discharged by said refrigerant evaporator and returning it to said refrigerant compressor, andvariable discharge volume means for reducing the discharge volume from the refrigeration cycle apparatus when a discharge pressure from said refrigeration cycle apparatus becomes higher than a first predetermined value,wherein said variable discharge volume means increases the discharge volume from said refrigeration cycle apparatus when the discharge pressure from said refrigeration cycle apparatus becomes lower than a second predetermined value.
