HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2012/014345
Kind Code:
A1
Abstract:
This heat pump comprises a first bypass pipe (6) and a second bypass pipe (40). One end of the first bypass pipe (6) is connected to a main pipe (5) connecting a compressor (1) to an indoor heat exchanger (2), and the other end of the first bypass pipe (6) is branched and connected to the main pipe (5) on the inlet side of each outdoor heat exchanger (4A, 4B). One end of the second bypass pipe (40) is connected to an injection port (43) which is in communication with a compression chamber being compressed in the compressor (1), and the other end of the second bypass pipe (40) is branched and connected to the main pipe (5) on the outlet side of each outdoor heat exchanger (4A, 4B). During a defrost operation for defrosting an outdoor heat exchanger (4A, 4B), part of the refrigerant discharged from the compressor (1) is supplied from the first bypass pipe (6) to the outdoor heat exchanger to be defrosted, and is then passed through the second bypass pipe (40) and injected from the injection port (43) of the compressor (1).
