ABSTRACT:
In a refrigerating cycle, a heat radiation of a gas cooler is reduced by a heat radiation reduction member when one of a pressure and a temperature of a high pressure side refrigerant is equal to or less than a predetermined value. When a discharge pressure of the refrigerant discharged from a compressor is equal to or lower than the predetermined level, the heat radiation of the gas cooler is reduced by the heat radiation reduction member. Thus, the refrigerant pressure of the high pressure side is increased while the refrigerant pressure of a low pressure side is decreased. With this, a flow rate at a high pressure inlet of an ejector is increased. Also, a flow rate at a low pressure inlet of the ejector is increased. Accordingly, a temperature of air blown from an evaporator is decreased without frosting the evaporator even when a load of the cycle is low.
