Abstract

The invention discloses a method for adjusting the air volume of a fan used in a gas water heater, which is specifically implemented according to the following steps: S1, the user inputs a preset temperature T 预设 ; S2, according to the preset temperature T in the S1 预设 Calculate the initial secondary pressure P 初始 , and according to the initial secondary pressure P 初始 Adjust the initial current I of the fan 初始 ; S3, gas water heater with the initial current I described in S2 初始 start; S4, according to the outlet water temperature, inlet water temperature and water flow rate to the initial secondary pressure P 初始 Adjust to obtain the actual secondary pressure P 实际 , and according to the actual secondary pressure P 实际 Calculate the actual current I of the fan 实际 ; S5, blower fan with the actual current I in the said S4 实际 run. The invention also discloses a gas water heater. The method for adjusting and controlling the fan air volume of the present invention does not need to increase additional costs, and only needs to adjust the fan current again according to the actual secondary pressure in the control program to solve the problem of unstable combustion of existing gas water heaters under different pressures.

Description

technical field

[0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a method for adjusting the air volume of a fan used in a gas water heater and the gas water heater. Background technique

[0002] In order to improve the wind resistance performance of gas water heaters, the application of DC frequency conversion fans to gas water heaters has appeared in the market;

[0003] However, the DC variable frequency fan basically adjusts the air volume according to the change of the gas proportional valve current, and this adjustment method cannot adapt to low gas pressure operation. When using proportional valve current adjustment, under normal gas pressure, the outlet water temperature is close to the preset temperature value, and the combustion is stable; Stable, the outside wind is easy to turn off the flame. Contents of the invention

[0004] In order to solve the above problems, the present invention provides a fan air vo...
