Air conditioning system design for a biological diagnostic reagent production base in Fuzhou

This paper presents the design for a biological diagnostic reagent production base in Fuzhou, focusing on its cold and heat sources and air conditioning water system. Considering the building’s functional requirement features and local climate characteristics, an efficient cold and heat source system is implemented by using efficient magnetic levitation variable frequency centrifugal chillers and four-pipe air-source heat pump units. This configuration meets both the thermal-moisture load characteristics and process requirements of pharmaceutical plants and the flexible and comfort demands of office areas. The operation strategy of the cold and heat source system is introduced, under which the cold and heat sources operate in the high-efficiency zone for most of the year. A comparative analysis of energy conservation and emission reduction benefits is conducted with the traditional system using variable frequency centrifugal chillers with gas-fired vacuum hot water boilers. The results show that the annual operating energy consumption of this high-efficiency cold and heat source system is lower than that of the traditional scheme.
