REFRIGERATING PLANT AND ITS STEAM DISPLACEMENT PUMP Russian patent published in 1994 - IPC

FIELD: refrigerating engineering. SUBSTANCE: in the refrigerating plant comprising a high-temperature line from compressor to throttle device and a low-temperature circuit with booster, evaporator and liquid space of circulating receiver the booster is made as a steam displacement pump provided with discharge line having impurity receiver, the source of steam has the form of double-walled heated vessel whose interwall space is connected to high-temperature line of refrigerating plant. Source of steam is connected with working space by pipeline. The length of pipeline built into working space is larger than 3/4 of its height and its diameter is 5-7 times smaller than nominal diameter of working space. EFFECT: improved functional and operating characteristics. 5 cl, 2 dwg
