PURPOSE:To provide the operation control method of an air-conditioner which is capable of being stabilized quickly at a set temperature without adjusting the opening degree of a hot-water flow rate regulating valve excessively. CONSTITUTION:An indoor temperature Tr is compared with a set temperature Ts upon starting heating operation and when Tr<=Ts, the opening degree of a hot-water flow rate regulating valve is set at a first initial stage opening degree set value thetas1, but when Tr>Ts, the opening degree is set at a second initial stage opening degree set value thetas2 to start the heating operation. After an initial time to has elapsed, indoor temperature control is effected based on fuzzy operation at every predetermined operating times DELTAt employing a temperature difference DELTAT and a hot-water indoor heat exchanger temperature changing amount DELTATh as input parameters. When the result of fuzzy operation indicates the control of opening the hot-water flow rate regulating valve, the valve is closed with a speed Vc when the temperature Th is higher than an upper limit specified value Thmax, the opening and closing operation is stopped when Thmax-delta<=Th<Thmax-alpha, the valve is driven into the opening direction with a slow opening and closing speed V when Th=Thmax-y while the valve is driven into the opening direction with a fuzzy opening speed Vfo when Th<=Thmax-y. |
