Title:
EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
Japanese Patent JP2019020062
Kind Code:
A
Abstract:
To provide an ejector-type refrigeration cycle which can suppress the lowering of an air-conditioning capacity caused by a pressure loss of an ejector or a suction-side decompression part.SOLUTION: A bypass passage 21 for introducing a refrigerant flowing out of an outdoor heat exchanger 14 to a refrigerant inlet side of a suction-side evaporator 19, and an opening/closing valve 22 for opening and closing the bypass passage 21 are arranged at an ejector-type refrigeration cycle having an indoor condenser 12, the outdoor heat exchanger 14, a flow-out side evaporator 18 for evaporating the refrigerant flowing out of a diffuser part 16d of the ejector 16, and a suction-side evaporator 19 for evaporating the refrigerant which is decompressed by a fixed throttle 17, and making the refrigerant flow out to a refrigerant suction port 16c side of the ejector 16. Then, by using the indoor condenser 12 as a heat radiator, the bypass passage is opened at dehumidification and heating at which the outdoor heat exchanger 14, the flow-out side evaporator 18 and the suction-side evaporator 19 are used as an evaporator.SELECTED DRAWING: Figure 1
