Abstract:
If a state continues for a first determination time period (TP1), said state being when the drive voltage of a pump (23) is set to an upper limit voltage and the opening degree of at least one of a plurality of flow adjustment valves (33, 43, 53) is set to the maximum opening degree, then the operation frequency of a compressor (11) increases at a first time (t2) so that the heat exchange amount of a second heat exchanger (22) increases. After the first time (t2), if either an operation stop request is input to or an indoor temperature (Tr) reaches a set temperature (Trs) in at least one of a plurality of third heat exchangers (31, 41, 51), then either an operation frequency (fc) of the compressor (11) decreases or a drive voltage (Vp) of the pump (23) decreases.
