Abstract:
1. A defroster of a refrigerant circuit, the refrigerant circuit including a compressor provided with an electric element, and first and second compression elements driven by the electric elements, these components being provided in a hermetically sealed container, refrigerant gas compressed by the first compression element being discharged into the hermetically sealed container, and the discharged refrigerant gas of intermediate pressure being compressed by the second compression element, a gas cooler, into which a refrigerant discharged from the second compression element of the compressor flows, a pressure reducing device connected to an outlet side of the gas cooler, and an evaporator connected to an outlet side of the pressure reducing device, a refrigerant discharged from the evaporator being compressed by the first compression element, the defroster comprising: a defroster circuit for supplying a refrigerant discharged from the first compression element to the evaporator without reducing pressure; and a flow path controller for controlling refrigerant distribution of the defroster circuit.
