ABSTRACT:
A cooling apparatus includes a bypass provided to a path extending from a compressor to an expansion valve via a condenser, and a unit for controlling a ratio of a flow rate of a refrigerant of the path via the condenser to that of the bypass path, or a unit for varying an air volume of a fan of an outdoor unit for blowing the condenser so as to vary a capacity of the condenser. The degree of superheat of the refrigerant is measured at an exit of the evaporator, and an expansion valve is controlled in accordance with the measured degree of superheat.
