Abstract：
This article presents the cold source and air conditioning system in the core technology area of the main media center of the Olympic Winter Games, discusses the determination of outdoor calculation parameters under the winter and spring cooling conditions, the configuration of the system, and the conversion after the game. The design conditions and actual operating parameters are compared and analysed, and the engineering design principles of the Olympic projects that operate temporarily for a short time and need to ensure that there is no mistake are summarized.
