Design of air conditioning and refrigeration system design for curling venue of National Aquatics Center

As the venue for the curling competition of the 2022 Olympic Winter Games, the National Aquatics Center builds a convertible ice plate on the swimming pool. The design scheme is determined by means of simulation calculation and combined with the measured data of the test competition. The dehumidification air conditioning for ice plate is designed, so as to ensure the air temperature, humidity and speed indexes above the ice, and meet the ice quality and competition environment requirements of the four curling tracks. The air conditioning systems for the audience are renovated. The environment near the ice surface and the auditorium are designed for different zoned air conditioning. On the premise of ensuring the events of the Olympic Winter Games, the concept of conservation, environmental protection and sustainable development is implemented. The design parameters and the refrigeration system design meet the technical requirements of the World Curling Federation. The ice making system is designed in accordance with the convertible and movable mode to fulfill the repeated, comprehensive and long-term utilization of venues.
