Embodiment
[0025] An adaptive control method for a finned tube coating dehumidification unit is used for switching between dehumidification and regeneration of two finned tube heat exchangers. Specifically, humidity sensors are installed in both the air supply chamber and the exhaust chamber of the dehumidifier unit, and the change of absolute moisture content is analyzed according to the temperature and humidity data collected by the sensors. Determine the degree of dehumidification or regeneration according to the change rate of absolute moisture content, so as to judge the completion of the dehumidification and regeneration process, and automatically control the switching of the air valve and water valve according to the set target humidity requirements, so as to realize the dehumidification and regeneration conditions. conversion to meet the set humidity target value.
[0026] Specifically, the temperature and humidity sensors collect data at intervals Δt to obtain the absolute moist...

The invention discloses an adaptive control method for a finned tube type coating dehumidification unit and relates to the technical field of adsorption dehumidification units. The control method is used to switch between dehumidification and regeneration of the two finned tube heat exchangers inside the unit. Temperature and humidity sensors are respectively installed in the air supply chamber and exhaust chamber of the unit, and the absolute humidity is analyzed according to the temperature and humidity data collected by the sensors. Determine the degree of dehumidification or regeneration according to the change rate of absolute humidity, so as to judge the completion of the dehumidification and regeneration process, and realize the automatic conversion of dehumidification and regeneration conditions according to the set target humidity requirements. By installing temperature and humidity sensors at the air supply port and air exhaust port, monitor the change of humidity, compare the humidity and its change rate with the set value, judge the dehumidification and regeneration of each finned tube heat exchanger, and determine the best switching The timing of dehumidification and regeneration conditions enables the unit to adapt to different operating environments, and automatically, continuously and stably send out air at different humidity settings.
Description
technical field [0001] The invention relates to the technical field of adsorption dehumidification units, in particular to an adaptive control method for finned tube coating dehumidification units. Background technique [0002] At present, indoor air dehumidification mainly adopts two relatively mature technologies: surface cooling and dehumidification, and rotor adsorption dehumidification. Surface cooling and dehumidification products use the surface with a temperature lower than the air dew point to condense water vapor to reduce air humidity. The technology has the advantages of simple and reliable way of obtaining, continuous supply of cold source and continuous operation. But cooling and dehumidification are coupled, and dehumidification must lower the temperature. In some occasions, it needs to be dehumidified and reheated, resulting in low dehumidification efficiency and high energy consumption; in addition, due to dew point dehumidification, the dew point temperatu...
