Abstract：
This paper presents the design of the cold and heat sources, heating and air conditioning water systems, air conditioning air systems and anti-freezing measures, etc. for the gymnasium. Combined with the gymnasium’s function and the local dry-heat climate features, using indirect evaporative chillers provides high-temperature chilled water for floor radiation cooling system and pre-cooling section of air conditioning units of competition hall seat-air-supply system. This paper analyses the measures of anti-freezing in depth and proposes a method to confirm the minimum opening of electric regulating valves in an outdoor air pre-heating system.
