Abstract:
An accumulator module applied to a vapour-compression type refrigerating machine in which decompressed refrigerant is evaporated so as to absorb heat and the thus evaporated refrigerant is sucked into and compressed by a compressor (110), comprising:an accumulator (140) for separating refrigerant into gas-phase refrigerant and liquid-phase refrigerant and storing redundant refrigerant therein, the thus separated gas-phase refrigerant flowing out from the accumulator (140) onto the suction side of the compressor (110); a pressure reducing device (161a) for decompressing the refrigerant on the high pressure side which is compressed by the compressor (110) and cooled after that, said pressure reducing device being integral with said accumulator; and an internal heat exchanger (150) for conducting heat exchange on the refrigerant on the low pressure side which is decompressed by the pressure reducing device (161a), before it is sucked into the compressor (110), wherein the pressure reducing device (161a) is fixed to the accumulator (140), and the internal heat exchanger (150) is housed in the accumulator (140).
