HVAC Design for assembled structure temporary buildings of Olympic Winter Games in Zhangjiakou

The assembled structure temporary building can be assembled quickly and adapt to different scenarios, which has been widely used in the 2022 Paralympic Winter Games, but its warmth is a technical problem that needs to be solved. Taking the prefabricated temporary building in Zhangjiakou competition area as an example, this paper presents the general engineering situation, architectural characteristics, special requirements of indoor environment design, thermal performance requirements of maintenance structure, heating load and power supply demand, as well as the special requirements of heating and ventilation terminal forms. It provides a reference for the HVAC design of assembled structure temporary buildings in winter in the future.
