Abstract
A vapor compression refrigeration circuit comprises a compressor, a heat radiator, a high-temperature section of an internal heat exchanger, a pressure reducer, an evaporator, an accumulator and a low-temperature section of the internal heat exchanger disposed in this order in a circulation passage through which a refrigerant circulates, when viewed along a direction of flow of the refrigerant. The pressure reducer, the accumulator and the internal heat exchanger are integrally formed.
