Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0013] The AC fan controls the speed of the AC fan by controlling the conduction angle of the AC fan. The larger the conduction angle, the greater the fan speed.
[0014] According to the experimental test, the relationship curve between the conduction angle and the speed of the AC fan is parabolic. When the fan speed is in the range of 1300-2000 rpm, the relationship between the speed and the conduction angle of the AC fan is linear, that is, by adjusting the conduction angle The pass angle can linearly adjust the speed of the AC fan.
[0015] Such as figure 1 As shown, the gas water heater blower anti-wind pressure control method based on the AC blower in this embodiment includes the following steps:
[0016] After the water heater starts to burn, first calculate the corresponding AC fan speed V0 according to the required heating energy of...
