Title:
EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
Japanese Patent JP2019020063
Kind Code:
A
Abstract:
To provide an ejector-type refrigeration cycle which can achieve both the suppression of the lowering of a cooling capacity and the suppression of the enlargement of a temperature distribution of a cooling objective fluid.SOLUTION: One high-pressure refrigerant which is branched at a branch part 14 is made to flow into a nozzle part 15a of an ejector 15, and the other high-pressure refrigerant branched at the branch part 14 is made to flow into a variable throttle mechanism 16. A part of a flow-out side evaporation part 18a for evaporating the refrigerant flowing out of the ejector 15 is formed at a leeward-side evaporator 18, and a suction-side evaporation part 18b for evaporating the refrigerant which is decompressed by the variable throttle mechanism 16 and making it flow out to a refrigerant suction inlet 21b side of the ejector 15 is formed. Then, a throttle opening of the variable throttle mechanism 16 is adjusted so that a temperature difference ΔTe between a flow-out side evaporation temperature Te1 at the flow-out-side evaporation part 18a and a suction-side evaporation temperature Te2 at the suction-side evaporation part 18b reaches a reference temperature difference KΔTe or smaller.SELECTED DRAWING: Figure 1
