一次回风全空气空调系统的节能改造
Energy conservation transformation of primary return air of all-air air conditioning system
摘要：
对露点送风的一次回风全空气空调系统和再热送风的一次回风全空气空调系统进行节能改造，提出改变后的一次回风全空气空调系统。介绍了这三种系统的空气处理过程，并结合工程实例进行分析。结果表明，改造后的系统不需要消耗再热量就能满足设定的送风温差，且可利用高温冷源，具有一定的节能性。

Abstract：
To improve the energy efficiency of the system, transforms the dew point supply air system and reheat supply air system, and puts forwards a transformed system. Presents the air handling process of the three systems, and analyses with a practical project. The results show that the transformed system can satisfy the supply air temperature difference set values without reheat energy consumption and utilize the high temperature cold source, and thus have better energy efficiency.
