Abstract (en)
A vapor compression refrigeration circuit comprises a compressor (14), a heat radiator (16), a high-temperature section (48) of an internal heat exchanger (28), a pressure reducer (22, 64, 68), an evaporator (18), an accumulator (24) and a low-temperature section (52) of the internal heat exchanger (28) disposed in this order in a circulation passage (4) through which a refrigerant circulates, when viewed along a direction of flow of the refrigerant. The pressure reducer (22, 64, 68), the accumulator (24) and the internal heat exchanger (28) are integrally formed.
