Abstract (en)

[origin: EP2226594A1] A refrigerator is provided in which a refrigerant supplied to an evaporator is precooled to a dryness of nearly zero and is supplied in a single liquid phase to increase the amount of heat exchanged by the evaporator, thereby improving cooling performance or reducing the size of the evaporator. A refrigerator (1) has a refrigeration cycle (8) formed by sequentially connecting a compressor (2) that compresses a refrigerant, a condenser (3) that condenses the high-pressure gas refrigerant, an economizer (4) that evaporates some of the condensed liquid refrigerant to cool the liquid refrigerant by means of the latent heat of evaporation thereof and that has a circuit for injecting the evaporated medium-pressure refrigerant into an intermediate inlet of the compressor, an expansion valve (5) that adiabatically expands the liquid refrigerant, and an evaporator (7) that evaporates the adiabatically expanded refrigerant, and a refrigerant precooler (15) that precools the refrigerant supplied to the evaporator (7) is disposed between the economizer (4) and the evaporator (7).
