Refrigerating apparatus
Abstract:
An object of the present invention is to keep an appropriate high pressure side pressure in a refrigerant circuit while reducing noises of an operation of a blower in a refrigerating apparatus which obtains a critical pressure on a high pressure side. The refrigerating apparatus in which the refrigerant circuit is constituted of a compressor, a gas cooler, a reducing element and an evaporator to obtain a supercritical pressure on the high pressure side includes a blower which air-cools the gas cooler and a control device which controls this blower. This control device controls a revolution speed of the blower based on an outdoor temperature and an evaporation temperature of a refrigerant in the evaporator.
