Abstract
An air-conditioning device includes a main circuit in which a refrigerant circulates; a flow channel-switching unit that selects a certain parallel heat exchanger as a defrosting target; a bypass pipe; a temperature-detecting unit; and one or more processors. The processor(s) operates the flow channel-switching unit such that an operation mode is switched between a normal heating operation mode in which the parallel heat exchangers serve as evaporators and a defrosting heating operation mode in which one parallel heat exchanger is selected as the defrosting target to cause part of the refrigerant to flow thereinto via the bypass pipe and the other parallel heat exchangers serves as an evaporator. The processor(s) senses erroneous installation of an installed component based on a magnitude relationship between the detected temperatures in the parallel heat exchangers detected by the temperature-detecting unit.
