Abstract

This refrigeration system is an orifice-tube system constituting a refrigeration cycle in which a refrigerant passes through a compressor a condenser an orifice-tube an evaporator and an accumulator in this order and then returns to the compressor The condenser is constituted by the so-called multi-flow type heat exchanger having a plurality of passes P -P The intermediate pass P is constituted as a decompression pass for decompressing the refrigerant. After condensing the refrigerant by the first pass P the condensed refrigerant is decompressed and evaporated by the decompression pass P and then the evaporated refrigerant is re-condensed by the third pass P This refrigeration system is excellent in response characteristic to thermal load fluctuations and in refrigeration performance.
