Abstract (en)
A refrigeration cycle apparatus (1) includes a compressor group (3), a four-way valve (5), a first heat exchanger (7), an expansion valve (9), a second heat exchanger (11), an accumulator (13), and an oil storage (15). The oil storage (15) is connected to the discharge side of the compressor group (3) via a discharge gas bypass pipe (17) provided with a first solenoid valve (19). The oil storage (15) is connected to the accumulator (13) via a first oil bypass piping (21) provided with a second solenoid valve (23). The oil storage (15) is connected to the compressor group (3) via a second oil bypass pipe (25) provided with a third solenoid valve (27).
