Abstract：
Presents the situation and existing problems of the air conditioning system in the Palace Museum’s underground treasures storage, and puts forward a reformation scheme of air conditioning system. Based on the measured data of typical day, calculates the air conditioning design indoor load, and determines the air handling process. In addition, proposes a fine adjustment method of the relative humidity in the storage, the improved measures of outdoor air supply and the alternative refrigerant suitable for the air conditioning unit of this project.
