Design of HVAC system for Winter Olympic venue group in Guyangshu

 This paper presents the design of HVAC systems for the three venues in the Zhangjiakou Chongli competition area of the Beijing Winter Olympics—the National Ski Jumping Center, the National Biathlon Center and the National Cross-Country Skiing Center. Combined with the local climatic characteristics, the different heat source methods are analysed and compared, and the heating effect of the selected electric heating and heat pump-multi split air conditioning system is tested and analysed. The results show that the indoor temperature meets the design requirements.
