HVAC design and research of National Speed Skating Oval

The National Speed Skating Oval undertook the avenue speed skating competition and training during the 2022 Olympic Winter Games. Its design goal is to meet the requirements of the green energy saving and science and technology Olympic Winter Games, and to build good technical conditions for athletes to achieve good results. This paper introduces the research on the indoor thermal and humidity environment construction of the National Speed Skating Oval, the design method of HVAC, etc., and verifies the suitability and innovation of the HVAC design of the project through energy saving effect and the actual measurement of the temperature and humidity of the competition hall during the Olympic Winter Games, and provides a new solution for the HVAC design of the avenue Speed Skating Oval.
