室外温度较低时如何提高空调冷水机组的适应性

Adaptability of Air-conditioning Water Chilling Units to Lower Outsdie Temperature

根据空调冷水机组本身的运行原理和特性改造空调冷却水管路系统,通过调节冷凝器水温的方法来调节冷凝器的压力,使其稳定在空调冷水机组要求的范围之内,以实现室外温度较低条件下空调冷水机组能够正常运行。摸索出一种科学合理、简单易行的空调冷水机组的调节方法,并已将其应用到北京地铁6号线工程的设计之中。

Methods of transforming cooling water through the pipeline system are adopted, which are based on the operation principle of water chilling unit, and will regulate the condenser water temperature to make the condenser pressure within the scope of water chilling unit requirements, in order to keep water chilling unit in normal operation when the outdoor temperature is lower. This scientific, reasonable,simple and easy operation scheme has been applied in the design of Beijing subway Line 6.
