This article presents a new scheme of air distribution for air conditioning systems of indoor ice arenas and proposesa method of calculating parameters of the microclimate zone of the ice field in this scheme. The developed “mixed scheme” differs from existing ones by adoption of multi-stage mixing of outdoor and recirculated air, removed from the upper and lower parts of the maintained area of the premises. To calculate the parameters of the microclimate zone of the ice field a graphic-analytical method using IDdiagrams was adopted. The results of numerical calculations show that the implementation of air distribution in the cold season according to the proposed scheme reduces energy costs for heating of supplied air bypossibly 15%, compared to the most economical of existing schemes.
