Title:
HEAT EXCHANGE DEVICE, REFRIGERATION SYSTEM, AND HEAT EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2017/170139
Kind Code:
A1
Abstract:
Since improving heat exchange between a gas-phase refrigerant and a liquid-phase refrigerant in a refrigeration system could instead result in a reduction in the efficiency of the refrigeration system as a whole, the present invention provides a heat exchange device (201) comprising: a refrigerant supply means (210) for supplying a first-temperature liquid-phase refrigerant (R11) and a second-temperature gas-phase refrigerant (R12) in one circulation system; a plurality of heat exchange means (220A, 220B) which are each configured so as to perform heat exchange between the liquid-phase refrigerant (R11) and the gas-phase refrigerant (R12); and a refrigerant circulation means (231, 232, 242) for circulating the gas-phase refrigerant (R12) in such a manner that the gas-phase refrigerant (R12) flows in parallel in the plurality of heat exchange means, and circulating the liquid-phase refrigerant (R11) in such a manner that the liquid-phase refrigerant (R11) flows in series in the plurality of heat exchange means.
