洁净手术室空调系统热湿处理过程探讨
Air handling processes of air conditioning system for clean operating room
摘要：
分析了洁净手术室空调采用一次回风系统、二次回风系统及由新风负担全部湿负荷的湿度优先控制系统的热湿处理过程。以某工程项目为例进行了计算，结果表明：湿度优先控制系统易于实现和控制，采用常规冷水盘管与机械制冷相结合的双冷源冷却除湿可满足系统对新风的处理要求，与传统一次回风系统相比，湿度优先控制系统具有显著的节能效果。
Abstract：
Analyses the heat and moisture handling processes of three different air conditioning systems—the primary return air system, secondary return air system and humidity priority control system in which the fresh air eliminates the whole moisture load. Calculates a project example and the results show that the humidity priority control system is easy to achieve and control; the fresh air handling requirement can be satisfied by the dual cold sources equipped with conventional cooling coil and mechanical refrigeration; the humidity priority control system has more significant energy saving effect than the primary return air system.
