Abstract：
This paper presents the design of the air conditioning system for a free electron laser facility, which mainly includes the cold and heat source system and the air handling system. According to the characteristics that the five working wells distribute in different bases, a cold and heat source system is set up for each base. To meet the high-precision temperature control requirement of ±0.1 ℃ for the wiggler tunnel, various interference factors affecting the temperature control accuracy are analysed and the key factors are found. Based on this, a high-precision temperature control air conditioning system with a water mixing function is designed. This paper proposes air conditioning equipment vibration control measures for the 150 nm micro-vibration requirement of the scientific facility.
