TEMPERATURE CONTROL VALVE AND REFRIGERATION CYCLE SYSTEM PROVIDED WITH SAME TEMPERATURE CONTROL VALVE

摘要

A temperature control valve comprises a valve body (64) that is provided in a circuit in which a refrigerant circulates and is displaced for controlling the flow rate of the refrigerant, and a temperature sensing unit (66, 66A, 66C, 10, 12) that changes a valve opening by displacing the valve body according to the refrigerant temperature. Frost formation is suppressed by way of controlling so that the temperature of an evaporator (5) is not less than a prescribed set temperature. Moreover, frost generation in a plurality of refrigerants of different types can be suppressed if the prescribed set temperature is set be high enough so that frost is not generated for the plurality of refrigerants of different types.
