the microcomputer control system adjusts the actual water yield of the water outlet proportional valve and/or the actual output power of the combustion assembly according to the following formula, so that the actual water outlet temperature of the gas water heater is preferably equal to the set temperature of the gas water heater:
t is set = Lmax T out/lri;
t is set as the set temperature of the gas water heater, Lmax is the maximum output water volume of the gas water heater, Tout is the water outlet temperature when the maximum output water volume of the gas water heater is achieved, L is the actual water outlet volume adjusted by the gas water heater, Lmax T/L is the actual water outlet temperature adjusted by the gas water heater, and the temperature value of Tout is calculated by the microcomputer control system according to the water inlet temperature and the actual output power of the combustion assembly.
In the above steps, when the set temperature is higher than the outlet water temperature, the microcomputer control system preferentially increases the actual output power of the combustion assembly, so that the actual outlet water temperature is preferentially equal to the set temperature, and when the actual output power of the combustion assembly reaches the maximum value and the set temperature is still higher than the actual outlet water temperature, the microcomputer control system reduces the actual outlet water amount of the outlet water proportional valve, so that the actual outlet water temperature is preferentially equal to the set temperature.
