Abstract
A vapor compression refrigeration system includes a subcooler provided between a condenser and an evaporator, which is formed by a heat exchanger integrally having a primary side and a secondary side into which a refrigerant which has passed through the primary side flows and in which the primary side and the secondary side have the same heat transfer area and capacity. An expansion valve is provided at a refrigerant entrance on the secondary side of the subcooler, and a primary expansion valve is provided at a refrigerant entrance on the primary side of the subcooler to which the refrigerant is introduced in a vapor compression refrigeration cycle having stages of compression, condensation, expansion and evaporation of the refrigerant. A bypass is provided in the primary expansion valve at the refrigerant entrance on the primary side.
