Document Type and Number:
WIPO Patent Application WO/2020/164215
Kind Code:
A1
Abstract:
A refrigerant circulation system and an air conditioner. The refrigerant circulation system comprises a first centrifugal compressor (1), a second centrifugal compressor (2) connected in series with the first centrifugal compressor (1), a first heat exchanger (5) communicated with the second centrifugal compressor (2) and used for allowing a compressed refrigerant to condense and release heat in the first heat exchanger (5), and second heat exchangers (13) communicated with the first heat exchanger (5) and used for allowing the condensed refrigerant to evaporate and absorb heat in the second heat exchangers. The air conditioner comprises the refrigerant circulation system. The refrigerant circulation system improves the cooling or heating effect of the air conditioner.
