Electric heating type air humidification control method and system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of air humidification, in particular to an electric heating type air humidification control method and system. Background technique [0002] In industrial production, many products have high requirements on the air humidity and temperature in the processing workshop. The air temperature and humidity change with the seasons, and the required air is sent into the room by the air supply equipment of the air conditioning system. Air humidifiers are usually used in air conditioning systems to humidify the air. [0003] Usually, the electric humidifier needs a period of time to heat the water at room temperature to the boiling point in the initial stage of humidification. , and during the humidification process, the electric heater can only run at full power, which will waste a lot of electricity. [0004] Usually the air conditioning system uses the air humidity monitor to detect the air humidity, but basicall...
