REFRIGERATING SYSTEM AND CONDENSER FOR DECOMPRESSION TUBE SYSTEM

摘要

A refrigerating system, comprising an orifice tube system having such a refrigerating cycle that refrigerant flows through a compressor (1), a condenser (10), an orifice tube (3), an evaporator (4), and an accumulator (5) in that order and returns to the compressor (1), the condenser (10) further comprising a multi−flow type heat exchanger having a plurality of paths (P1) to (P3), wherein the intermediate path (P2) is formed as a decompression path for reducing the pressure of the refrigerant, after the refrigerant is condensed by the first path (P1), the condensed refrigerant is decompressed and evaporated by the decompression path (P2), and the evaporated refrigerant is re−condensed by the third path (P3), whereby excellent response characteristics to a variation in a thermal load on the condenser and a sufficient refrigerating performance can be provided.
