Abstract
In a method and an apparatus for injecting mixed refrigerant into a refrigerant circuit comprising at least a compressor, a condenser, an expansion device and an evaporator which are connected to one another through a refrigerant pipe, the mixed refrigerant is intermittently injected from a refrigerant bomb at a predetermined position of a low pressure side of the refrigerant circuit while keeping the mixed refrigerant in a liquid state. The intermittent injection operation (amount) of the liquid refrigerant into the refrigerant circuit may be controlled on the basis of the degree of superheat of the mixed refrigerant in the refrigerant circuit.
