摘要： PURPOSE: A very low temperature multi-cooling system is provided to realize a very low temperature by stable operation, and improve the cooling efficiency. CONSTITUTION: A basic cooling cycle(10) connects a compressor(11), a condenser(12), and a heat exchanger(13) to circulate a refrigerant. An evaporator(31) is separated from the basic cooling cycle. A plurality of main vapor-liquid separators(42,43,44) are arranged in order in association with a refrigerant supply path between the heat exchanger and the evaporator to separate a mixed refrigerant into a vapor refrigerant and a liquid refrigerant. A refrigerant return pipe(51) connects the evaporator and the heat exchanger. The liquid refrigerant returns to the heat exchanger through the refrigerant return pipe. The vapor refrigerant is condensed by passing condensing pipe paths(62,63,64) contained in the refrigerant return pipe to be supplied to a low temperature part of an upper stream. A zigzag-shape sub refrigerant return pipe(101) contains a mixed refrigerant flow pipe(33) connecting the heat exchanger with the utmost lower stream main vapor-liquid separator(42). A predetermined low voltage refrigerant of the sub refrigerant return pipe is jet to overcool the mixed refrigerant in the sub refrigerant return pipe.

摘要： PURPOSE: A cryogenic refrigerating system is provided to operate a refrigerating system continuously and stably by keeping evaporating pressure of refrigerant lower than suction pressure of a freezer, and to improve cooling efficiency and lengthen a life span by flowing refrigerant stably with throttling. CONSTITUTION: A cryogenic multi-stage refrigerating system is composed of a compressor(1) sucking and compressing mixed refrigerant; an oil separator(10) separating oil from compressed refrigerant; a condenser(2) liquefying refrigerant steam from the oil separator; a heat exchanger(3) evaporating refrigerant through a refrigeration cycle at low temperature, and supercooling condensed refrigerant; and a first gas-liquid separator(4-1) separating liquefied refrigerant and steam refrigerant from supercooled mixed refrigerant. Refrigerant from a final evaporator(14) is returned to the compressor. Liquid mixed refrigerant is injected through an expander(8-1) and a nozzle(7-1) to a double pipe(5-1), and streamed to an evaporation refrigerant moving pipe(6). Mixed refrigerant steam from the first gas-liquid separator is condensed with moving up through a condensing pipe, and flowed into a second gas-liquid separator(4-2). Condensed refrigerant is injected and evaporated, and returned to the compressor. Cooling efficiency is improved with flowing refrigerant stably by selecting mixed refrigerant according to stages.
