Abstract:
An air-conditioning device in which multiple heat-source-side units (A, B) having a compressor (10), a four-way valve (2), a heat-source-side heat exchanger (3), and an expansion valve (7), and one or more load-side units (X, Y) having a load-side throttle device (12) and a load-side heat exchanger (11), are connected by means of pipes, thereby forming a refrigerant circuit that circulates a refrigerant, said air-conditioning device being equipped with a control device (100) that controls the degree of opening of the expansion valve (7) and thereby controls the condensing of the refrigerant in the heat-source-side heat exchanger (3) when a defrosting operation, wherein refrigerant flows from the compressor (1) into the heat-source-side heat exchanger (3) and defrosting occurs, is performed.
