Abstract (en)
A refrigeration cycle device is provided with a heat source-side unit (100), a load-side unit (200) connected to the heat source-side unit via a first connection pipe (300) and a second connection pipe (400), and a control device (50). A first compressor (2), a first heat source-side heat exchanger (3), a first heat source-side decompressor (4), a sub-cooling heat exchanger (10), and a load-side heat exchanger (6) constitute part of a first refrigeration cycle that is connected via a refrigerant pipeline and that circulates a first refrigerant. During a cooling operation in which the load-side heat exchanger functions as an evaporator, control is carried out which causes the first refrigerant to flow into the first connection pipeline (300) as a liquid refrigerant having a pressure smaller than the design pressure of the first connection pipe.
