Abstract

The invention discloses a control method and device for a gas water heater. The control method comprises the steps that the current heating rate of the gas water heater is obtained; according to the relation between the current heating rate and the heating rate interval, the thermal load correction mode of the gas water heater is determined; and the thermal load of the gas water heater is adjusted in the thermal load correction mode. Through the arrangement, the thermal load correction mode of the gas water heater can be determined according to the relation between the current heating rate and the heating rate interval, and the heating power of the gas water heater is adjusted through the thermal load correction mode, so that the heating thermal load and the heating rate of the gas water heater can be adjusted and controlled. Therefore, the temperature rise overshoot can be reduced while the heating speed is increased.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a control method and control device for gas water heaters. Background technique [0002] The use of gas water heaters is very popular now. The gas water heater quickly heats the cold water flowing through the heat exchanger through the large amount of heat generated instantaneously when the gas is fully burned. Compared with electric water heaters, it has high heat exchange efficiency, low cost, and instant heat, which is favored by users. When the user is using a gas water heater, a period of cold water is usually discharged first after turning on the hot water tap, and then hot water can be used. [0003] From the principle of energy conservation, since the total heat required in the heating process is determined, and during heating, the greater the instantaneous heat load, that is, the greater the firepower, the shorter the required heating time. However, if the i...
