低温送风空调系统焓湿图分析
Psychrometric chart analysis of cold air distribution system
摘要：
分析了低温送风空调系统在新风直接引入和新风集中处理至室内空气状态点的等比焓线后引入空调机房两种情况下的空气处理过程，详细给出了空调器采用压出式风机配置时的焓湿图绘制步骤。介绍了采用不同末端型式的低温送风系统在冬、夏季负荷变化时的调节方法并进行了焓湿图分析。

Abstract：
Analyses the air handling process of cold air distribution system with outdoor air introduced to machine room directly or after being handled to the state of indoor air enthalpy. Presents in detail the drawing steps of the air state points in psychrometric chart for the air conditioning unit with blowing-through type fan. Presents the regulating method with different terminal units in varied load and performs the psychrometric analysis.
