The invention relates to the technical field of air humidification, and particularly discloses an
electric heating type air humidification control method and a
system. The method comprises the following steps: detecting a
dew point of an air outlet of air supply equipment, calculating the difference value
delta T1 of the
dew point and the
dew point set value of the air outlet, detecting the watertemperature of a water tank of a humidifier, and calculating the difference value
delta T2 of the
water temperature and the set value of the
water temperature; and obtaining the output quantity of SCRof the humidifier through PID operation according to the
delta T1 and the delta T2, and controlling the output power of the humidifier according to the output quantity of the obtained the SCR of thehumidifier. The output quantity of the SCR of the humidifier is obtained according to the difference value of the
dew point of the air outlet of the air supply equipment and the
dew point set value ofthe air outlet, and the difference value of the
water temperature of the water tank of the humidifier and the water temperature set value of the water tank of the humidifier, and the output power ofthe humidifier is controlled according to the acquired output quantity of the humidifier, so that the humidifier is not always in a high-power state, the
electric energy is saved, and the cost is saved. Meanwhile, the
dew point of air is measured by a dew point sensor, so that measured value is accurate.
