Abstract

The invention discloses a gas water heater control method and control system. The control method comprises an ignition step and a heating step. The ignition step comprises the following steps of: carrying out ignition for the first time, if the ignition is successful, executing the heating step, if the ignition is unsuccessful, according to environment humidity, regulating ignition gas pressure, and carrying out ignition again. The heating step comprises the following steps of: collecting a drained water temperature, if the drained water temperature is lowered than a preset temperature, collecting an environment temperature, according to the environment temperature, regulating heating gas pressure to carry out heating, and if the drained water temperature achieves a preset temperature, maintaining the heating gas pressure to carry out heating. By use of the technical scheme, in the ignition step, according to the environment humidity, the ignition gas pressure is regulated so as to improve an ignition success rate, in the heating step, if the drained water temperature is lower than the preset temperature, according to the environment temperature, the heating gas pressure is regulated for heating so as to improve the thermal efficiency of the gas water heater, and the gas water heater can be guaranteed to realize a constant temperature function.

Description

technical field [0001] The present invention relates to the technical field of gas water heaters, and more specifically relates to a control method and a control system of gas water heaters. Background technique [0002] Gas water heaters are currently the most widely used heat source products. The thermal efficiency of existing gas water heaters is mainly affected by gas pressure, air temperature, and air humidity. The reduction in thermal efficiency of gas water heaters means that the hot water production capacity of gas water heaters is reduced, making it difficult for the outlet water temperature of gas water heaters to reach the preset temperature. . In addition, the ignition success rate of gas water heaters is mainly affected by gas pressure and air humidity. [0003] The gas water heater in the prior art cannot control its gas supply according to the environmental parameters, resulting in the failure of the gas water heater to ignite successfully or to realize the ...
