Energy saving control of dual-channel air conditioning box with psychrometric calculation

In order to solve the excessive energy consumption problem in ordinary air conditioning box, such as high reheating capacity in summer and low utilization rate of outdoor air in transitional season, proposes a method to control the supply air temperature and humidity using psychrometric calculation, which adjusts the temperature and humidity with a dual-channel air conditioning box. This method can effectively eliminate the super cooling problem caused by the dehumidification of the air supply, so as to reduce the reheating steam consumption caused by dehumidification and realize the energy saving control in the transitional season by full use of outdoor air. Meanwhile, it can eliminate the irrational phenomenon of cold and heat counteraction in summer and save about 30% energy of air conditioning control area.
