A Scheme and Method of Calculation for Ventilation and Air Conditioning Systems of Ice Arenas

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