Clean air conditioning outdoor air treatment method analysis and schemes for operating department

 In view of the humidity deviation of air treatment mode commonly used in the clean air conditioning system of the operating department at present, proposes four schemes and calculates the moisture load. Through comparative analysis, selects the fourth scheme, that is, the outdoor air handling unit is equipped with a primary water-cooled surface cooler, and the cool and dry outdoor air is treated to be subcooled and subdried and mixed with part of the return air for the first time, the other part of the return air is cooled and dehumidified in the circulating unit and mixed with the primary mixed air for the second time, and then heated or cooled to fine-tune the air supply temperature.
