Title: REFRIGERATION CYCLE DEVICE
Abstract:
This refrigeration cycle device (50) comprises a refrigerant circuit which circulates a nonazeotropic refrigerant mixture. The refrigerant circuit includes a compressor (1), an outdoor heat exchanger (5), an indoor heat exchanger (8), an expansion valve (7), and a four-way valve (2). The four-way valve (2) is configured so as to be capable of assuming a first state (cooling) and a second state (heating). The outdoor heat exchanger (5) includes a plurality of refrigerant flow paths (10a, 10b) and a linear flow path switching valve (12) that switches the connection of the plurality of refrigerant flow paths (10a, 10b) between a series state, in which the refrigerant flows in series, and a parallel state, in which the refrigerant flows in parallel. A control device (30) switches the linear flow path switching valve (12) between the series state and the parallel state when a multidirectional valve is in the second state (heating).
