COOL WATER PRODUCING SYSTEM OF WATER VAPOR COMPRESSION REFRIGERATING MACHINE WITH VAPOR EJECTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To operate a water vapor compression refrigerating machine at a high efficiency by providing the water vapor compression refrigerating machine with a vapor ejector device.;SOLUTION: This water vapor compression refrigerating machine 17 comprises an evaporator 17a, a compressor 17b, an intermediate condenser 17c, and a condenser 17d. The evaporator 17a leads circulating cool water 18, evaporates a part of the circulating cool water 18 while maintaining at a low pressure by the operation of the compressor 17, and produces cool water by the latent heat thereof. The intermediate condenser 17c and the condenser 17d allow vapor pressurized and heated by the compressor 17b to pass therethrough, and cools the vapor by cooling water 19 led therein from the outside for condensation. The vapor ejector device 20 is installed on the vapor compression refrigerating machine 17, and sucks vapor in the intermediate condenser 17c from the other inlet side by using, at one inlet side, drive vapor 20a from the outside. The vapor is pressurized and discharged to the condenser 17d by the operation of the vapor ejector device 20.;COPYRIGHT: (C)2004,JPO
