Abstract (en)
[origin: EP2693139A1] A refrigeration cycle apparatus includes: a compressor; a fan (95a-95d) for heat source-side heat exchangers (4); multiple heat source-side heat exchangers (4) which exchange heat with air and are divided in the direction of height and grouped from a position close to the fan (95a-95d), including heat exchanger groups (401, 402, 403); an expansion valve (5); a use-side heat exchanger (6) which exchanges heat with a use-side heat conveying medium; a refrigerant pipe which sequentially connects the compressor (2), heat source-side heat exchangers (4), expansion valve (5), and use-side heat exchanger (6) and circulates refrigerant; and a controller (10) which controls the quantity of refrigerant flowing into each of the heat exchanger groups according to a load factor. As a result, the following can be implemented when the wind speed distribution of the heat source-side heat exchangers (4) is ununiform in the vertical direction: even in part load operation in which capacity requirement varies, refrigerant can be more appropriately distributed to the heat source-side heat exchangers and the period coefficient of performance (COP) for a refrigeration cycle apparatus can be enhanced.
