Document Type and Number:
Japanese Patent JP6320567
Kind Code:
B2
Abstract:
An air-conditioning apparatus is capable of efficiently performing defrosting operation without suspending a heating operation of an indoor unit. The air-conditioning apparatus includes a main circuit (50) sequentially connecting, via a pipe, a compressor (1), indoor heat exchangers (3b and 3c), first flow control devices (4b and 4c), and a plurality of parallel heat exchangers (5-1 and 5-2) connected in parallel to each other to allow refrigerant to circulate, first defrost pipes (39-1 and 39-2) branching a part of the refrigerant discharged from the compressor 1 and causing the part of the refrigerant to flow into one of the plurality of parallel heat exchangers (5-1 and 5-2) to be defrosted, an interface heat exchanger (11) located between the plurality of parallel heat exchangers (5-1 and 5-2), a first bypass pipe (37) branching a part of the refrigerant discharged from the compressor (1) and causing the part of the refrigerant to flow into the interface heat exchanger (11), and a second bypass pipe (38) causing the part of the refrigerant flowing out of the interface heat exchanger (11) to flow into the main circuit (50).
