Abstract

The invention belongs to the technical field of gas water heaters, and discloses a control method of a gas water heater and the gas water heater. The control method is characterized in that based on different openings of gas valves, gas has different quantities of heat production in unit time in gas combustion, different heat conversion optimal efficiencies are set for the different quantities ofheat production, when the quantity of heat production is fixed, the instant efficiency and the optimal efficiency of heat conversion are compared, and when the different value between the instant efficiency and the optimal efficiency is larger than the allowable value, the water flow of the gas water heater is adjusted. The gas water heater is controlled by using the control method of the gas water heater. According to the control method and the gas water heater, the optimal efficiency is taken as an index, the water flow is adjusted according to the comparison result of the instant efficiencyand the optimal efficiency, and the gas water heater is intelligently variable, so that the gas water heater is automatically adjusted to the optimal state to work, the unnecessary actions of a device are reduced, the error rate is reduced, heat generated in gas combustion can be sufficiently utilized, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a control method of a gas water heater and a gas water heater. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel to transfer heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. When the existing gas water heater is working, the heat generated by gas combustion cannot be fully converted, so that the gas cannot be burned at its optimal efficiency, resulting in waste of energy. Contents of the invention [0003] The object of the present invention is to provide a gas water heater control method and a gas water heater, which can fully utilize the heat generated by gas combustion. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A control method for a gas water heater, ...
