Title:
REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/061624
Kind Code:
A1
Abstract:
A refrigeration system, wherein, even if the refrigeration cycle thereof uses a refrigerant in a supercritical state, the refrigerant supplied to an expander can be sufficiently cooled into a liquid-like state to improve the coefficient of performance (COP) to thereby improve the refrigeration ability.
An inner heat exchange element (30) is provided so as to bridge piping between a heat dissipator (13) and an expander (18) and piping between an evaporator (20) and a compressor (10). An accumulator (40) is provided in piping located downstream of the inner heat exchange element (30) and between the inner heat exchange element (30) and the compressor (10).
