置换通风在某车间空调改造中的应用

分析了原有工程空调系统存在的夏季室温降不下来、室内空气品质差等问题，改造设计中采用了水平置换通风空调系统，改造后空调系统运行良好。介绍了设计经验，认为置换通风空调方式在大空间工艺性空调中使用有其优越性，提出了发展这种空调方式尚需解决的一些问题。

Displacement ventilation used in reforming the air conditioning system in a workshop

Analyses the problems existed in the old air conditioning system in a workshop, including higher temperature and poor air quality. Adopts horizontal displacement ventilation in the reformed system design, which proves to work well. Presents the design experience and considers it advantageous to use the displacment ventilation air conditioning system in large space workshops. Puts forward some issues need to be solved in developing this mode.
