Abstract
An air conditioning apparatus includes a plurality of third heat exchangers and flow rate control valves. In a heating mode, a controller opens a flow rate control valve corresponding to a heat exchanger that is being requested to perform air conditioning of the plurality of third heat exchangers, and closes a flow rate control valve corresponding to a heat exchanger that is not being requested to perform air conditioning of the plurality of third heat exchangers. In a defrosting mode, when a temperature of a second heat medium is lower than a first determination temperature, the controller opens a flow rate control valve corresponding to at least one of the heat exchangers that are not being requested to perform air conditioning. The at least one of the heat exchangers is assigned a higher priority than a remaining heat exchanger that is not being requested to perform air conditioning.
