二次回风空调系统在某体育馆工程中的应用

Application of Secondary Return Air Conditioning System in Gymnasium Project

二次回风系统常用于座椅下送风,以满足送风温度较高的要求,其控制策略直接关系到室内温湿度环境及节能效果。通过对一、二次回风系统运行能耗的比较,介绍了某体育馆比赛大厅观众区二次回风空调系统的系统设置及其自控策略。分析了二次回风系统在该条件下的节能效果。

Secondary return air conditioning system is always used in the under-seat air supply system to obtain a higher supply air temperature, and its control strategy directly affects the temperature and humidity of inner environment;By the comparison on energy consumption between the air conditioning system with secondary return air and the system with primary return air, presents air conditioning system and control strategy of the gymnasium, and analysis energy-saving effect of secondary return air conditioning system.
