Abstract:
A refrigerating cycle having a by-pass duct in juxtaposition therewith for supplying a refrigerant delivered by a compressor into an evaporator, wherein the refrigerant by passes a condenser, is adiabatically expanded by an expansion valve, and is evaporated and returned to the compressor, the refrigerating cycle comprising:an accumulator for temporarily storing the low-pressure refrigerant connected between an outlet of the evaporator and an inlet of the compressor, wherein the accumulator controls an amount of the refrigerant circulating in a heating mode of the refrigerating cycle that circulates through the by-pass duct without passing through the condenser; anda heat exchanger coupled to the accumulator, wherein the heat exchanger exchanges heat discharged from an energy source with the refrigerant received in the accumulator and includes a heat transferring medium controlled by a control valve.
