Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/047330
Kind Code:
A1
Abstract:
An air conditioner is provided which obtains improved power saving performance by avoiding decreases in refrigeration cycle efficiency. This air conditioner is provided with a main circuit which circulates a refrigerant and which comprises, sequentially connected with pipes, a compressor, a refrigerant flow path switching device, a load-side heat exchanger, a load-side throttle device, and multiple heat source-side heat exchangers. When using multiple heat source-side heat exchangers as a condenser, a first heat source-side heat exchanger and a second heat source-side heat exchanger are connected to each other in series, and when multiple heat source-side heat exchangers are used as an evaporator, the first heat source-side heat exchanger and second heat source-side heat exchanger are connected to each other in parallel. A distribution adjustment header for adjusting distribution of the refrigerant is provided in a position which, when multiple heat source-side heat exchangers are used as an evaporator, becomes the inlet-side refrigerant flow path of at least one of the first heat source-side heat exchanger and the second heat source-side heat exchanger.
