Discussion on air conditioning system scheme of an ice basket gymnasium in Lanzhou

The ice basket gymnasium integrates various functions such as indoor ice rink, basketball court, badminton and theatrical performances. Aiming at the complex use of the ice basket gymnasium and the high requirements for the adaptability and flexibility of the air conditioning system, takes the design of air distribution, the defogging of ice surface and the anti-condensation of the ceiling as the focus of the air conditioning system. Proposes the air conditioning system scheme and operation strategy suitable for the competition center, and predicts the indoor air distribution through CFD simulation to evaluate the expected effect. Based on the dimensionless velocity distribution diagram of the rotating jet, verifies the reliability of the simulation results. Finally, discusses the anti-condensation and defogging measures of ice rinks.
