Reconstruction design of air conditioning systems for Capital Indoor Stadium

 Short track speed skating and figure skating competitions of the Beijing 2022 Olympic Winter Games are held in Capital Indoor Stadium. To meet the competition requirements of the Olympic Winter Games, the air conditioning and dehumidification systems in the stadium should be reconstructed. Starting from the competition demands of the Olympic Winter Games and the objectives of environment control of the indoor artificial ice stadium, this paper analyses the heat and humidity load calculation and air treatment process of the air conditioning system, proposes the reconstruction design measures of the air conditioning and dehumidification system, and performs the simulation verification combined with different outdoor meteorological conditions. Through the test of actual competitions in the Beijing Olympic Winter Games, the air conditioning and dehumidification systems after reconstruction design achieve the expected design objectives and satisfactory results.
