Document Type and Number:
WIPO Patent Application WO/2018/054052
Kind Code:
A1
Abstract:
An air conditioner and a defrosting system thereof. The defrosting system comprises an enthalpy increasing compressor (11), an outdoor heat exchanger (12), an indoor heat exchanger (13) and an economizer (14); the enthalpy increasing compressor (11) comprises an intermediate pressure chamber and an enthalpy injection port which is in communication with the intermediate pressure chamber; the economizer (14) has a first flow channel (15) and a second flow channel (16); a first end of the first flow channel (15) is connected to the outdoor heat exchanger (12) by means of a first pipe line system (19), and a second end of the first flow channel (15) is in communication with the indoor heat exchanger (13) by means of a main path; a first end of the second flow channel (16) is connected to the main path by means of an auxiliary path, and a second end of the second flow channel (16) is connected to the enthalpy injection port of the enthalpy increasing compressor (11) by means of a second pipe line system (20); the second pipe line system (20) is provided with a valve device (18); the auxiliary path is provided with a throttling and pressure reducing member (17); a refrigerant, after being throttled and pressure-reduced by the throttling and pressure reducing member (17), enters the second flow channel (16) and can absorb heat of the refrigerant in the first flow channel (15). The defrosting system of the air conditioner can reduce defrosting time, satisfying the comfort requirement of a user.
