Filed: 1994-05-18
Abstract: PURPOSE:To stably control the capacity of a refrigerant circuit using a variable capacity type compressor by controlling an evaporating pressure by a constant- pressure expansion valve and controlling the capacity by a temperature sensitive capacity control mechanism. CONSTITUTION:When a cooling load becomes, if the capacity of a variable capacity type compressor is small, high, heat is excessively derived from refrigerant fed from a constant-pressure expansion valve 23 by an evaporator 24 so that the refrigerant becomes superheated vapor. A temperature sensitive capacity control mechanism 13 alters the pressure of a control pressure chamber 42c to the side of increasing the capacity in response to the temperature of the refrigerant of the superheated vapor state. When a cooling load is, if the capacity of the compressor is large, decreased, heat is not derived from the refrigerant fed from the valve 23 by the evaporator 24 so the refrigerant becomes wet vapor. The mechanism 13 alters the pressure of the chamber 42c to the side of decreasing the capacity in response to the temperature of the refrigerant of the wet vapor state. Thus, the capacity control of the refrigerant circuit using the compressor can be stably executed.
