Abstract (en)
[origin: EP3306204A1] A hot water heating system includes a room temperature sensor that detects room temperature information of a building; a heat source unit that generates hot water; an indoor unit that rejects heat of hot water generated by the heat source unit and heats the building; and a controller that controls the heat source unit. The controller includes a control gain determination unit that calculates a first gain and a second gain based on thermal properties of the building, a heating control unit that updates a hot-water discharge temperature command corresponding to a target value of a temperature of water at an outlet of a refrigerant-water heat exchanger by using the first gain and the second gain, and a hot-water discharge temperature control unit that, in a case of air-conditioning ON in which the indoor unit supplies heat to the building, outputs a heat supply command to the heat source unit based on the hot-water discharge temperature command updated by the heating control unit. The first gain is designed so that the hot-water discharge temperature command that results in intended room temperature response in the case of air-conditioning ON is obtained, and the second gain is designed so that the hot-water discharge temperature command reflecting a change in room temperature in a case of air-conditioning OFF in which the indoor unit does not supply heat to the building is obtained. The heating control unit updates, in the case of air-conditioning ON, the hot-water discharge temperature command by using a setting temperature for room temperature, the room temperature information, and the first gain, and updates, in the case of air-conditioning OFF, the hot-water discharge temperature command by using the setting temperature, the room temperature information, and the second gain.
