Abstract:
An air conditioning device (1000) comprises: a refrigerant circuit (500) which includes, at least, a compressor (200), a condenser (211), an expansion mechanism (230), and an evaporator (110), and which is configured to circulate a refrigerant; and a control device (100) for controlling the refrigerant circuit (500). One of the condenser and the evaporator includes a first heat exchanger (211) and a plurality of first fans (221, 222) having rotational speeds that can be controlled independently from one another by means of the control device (100). The control device is configured such that, if an operating frequency of the compressor is a predetermined lower limit frequency (Fmin), the rotational speed of at least one first fan (222) among the plurality of first fans can be made lower than the rotational speed of the remaining first fan (221).
