Document Type and Number:
Japanese Patent JP6945741
Kind Code:
B2
Abstract:
An air conditioning apparatus (1) includes a compressor (11), a first heat exchanger (13), a second heat exchanger (22) configured to exchange heat between a first heat medium and a second heat medium, a plurality of flow rate control valves (33, 43, 53), and a pump (23) configured to circulate the second heat medium between a plurality of third heat exchangers (31, 41, 51) and the second heat exchanger (22). In a heating mode, a controller (100) is configured to open the flow rate control valve corresponding to a heat exchanger, of the plurality of third heat exchangers (31, 41, 51), to which a request for air conditioning has been made, and to close the flow rate control valve(s) corresponding to a heat exchanger(s), of the plurality of third heat exchangers (31, 41, 51), to which the request for air conditioning has not been made. In a defrosting mode, when a temperature of the second heat medium is lower than a first determination temperature, the controller (100) is configured to open at least one of the flow rate control valve(s) corresponding to the heat exchanger(s) to which the request for air conditioning has not been made.
