EJECTOR REFRIGERATION CYCLE APPARATUS

WIPO Patent Application WO/2016/000652

A1

An ejector refrigeration cycle apparatus. An air vent of a compressor (101) is connected to an outdoor heat exchanger (103) via a conduit, the other end of the outdoor heat exchanger (103) is connected to a first electronic expansion valve (105) via a conduit, and the other end of the first electronic expansion valve (105) is connected to a gas/liquid separator (106) via a conduit; the gas/liquid separator (106) is provided with a gas outlet and a liquid outlet; the gas outlet is connected to a first inlet of an ejector (109) via a conduit, and the liquid outlet is connected to a second electronic expansion valve (107) via a conduit; the other end of the second electronic expansion valve (107) is connected to an indoor heat exchanger (108); the other end of the indoor heat exchanger (108) is connected to a second inlet of the ejector (109); an outlet of the ejector (109) is connected to a gas intake port of the compressor (101) via a conduit. When there is a change in the operating mode of the air conditioning, the working medium state and flow in the first inlet of the ejector (109) are adjusted by means of the first electronic expansion valve (105). This broadens the range of operating modes to which the ejector (109) may adapt and increases air conditioning energy efficiency.
