Title:
EVAPORATOR UNIT
Document Type and Number:
WIPO Patent Application WO/2017/154603
Kind Code:
A1
Abstract:
This evaporator unit is equipped with a gas-liquid separator (14, 24), a liquid reservoir (15), an ejector (16), a decompression device (19), and evaporators (17, 18). The gas-liquid separator separates a refrigerant into a gas-phase refrigerant and a liquid-phase refrigerant. The liquid reservoir retains the liquid-phase refrigerant. The ejector has a body (16b), which is formed with a nozzle (16a), a refrigerant suction port (16c), and a booster (16d). The nozzle decompresses the refrigerant containing the gas-phase refrigerant. The refrigerant suction port sucks the refrigerant as a suction refrigerant by the suction action of the high-speed jet refrigerant jetted from the nozzle. The booster mixes the jet refrigerant and the suction refrigerant, and raises the pressure. The decompression device decompresses the liquid-phase refrigerant flowing out from the liquid reservoir. The evaporators have discharge-side heat exchangers (17a, 18a, 17b) and a suction-side heat exchanger (18b). The discharge-side heat exchangers evaporate the refrigerant flowing out from the booster. The suction-side heat exchanger evaporates the refrigerant decompressed by the decompression device, and causes the refrigerant to flow into the refrigerant suction port.
