Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/068188
Kind Code:
A1
Abstract:
The present invention comprises: a branch portion (103) that branches the refrigerant flowing out of a condenser (104) into a main circuit (130) through an evaporator (108) and a bypass circuit (140) bypassing the evaporator (108); a merging portion (112) that merges the refrigerant from the main circuit (130) and the refrigerant from the bypass circuit (140); a first throttling means (106) for decompressing and expanding the refrigerant between the condenser (104) and the evaporator (108); a first inter-refrigerant heat exchanger (114) that exchanges heat between the refrigerant between the condenser (104) and the first throttling means (106) and the refrigerant between the merging portion (112) and the inlet of a compressor (102); a second throttling means (110) for decompressing and expanding the refrigerant branched at the branch portion (103), the second throttling means (110) being disposed in the bypass circuit (140); and a second inter-refrigerant heat exchanger (111) that is disposed in the bypass circuit (140) and exchanges heat between the refrigerant decompressed and expanded by the second throttling means (110) and the refrigerant flowing out of the condensation-side outlet of the first inter-refrigerant heat exchanger (114).
