Analysis of key and difficult points in air conditioning design for new Sanxingdui Museum

Taking the new Sanxingdui Museum project as an example, this paper analyses the configuration scheme of centralized air conditioning cold and heat sources. It conducts an economic analysis of different chiller capacity configuration schemes in the low-carbon composite cold source scheme combining air-source heat pumps and water-cooled chillers, and determines an economically suitable cold and heat source configuration scheme by comprehensively considering the backup capability of chillers, the converted annual cost, and the investment payback period. According to the design concept of high-efficiency machine rooms, it analyses and calculates the annual design energy efficiency ratio (EERa) of the cold source system. In addition, it elaborates on the design concept of the constant temperature and humidity air conditioning system for the collection storage rooms and the design scheme for high-reliability assurance.
