大温差低温送风空调机组在地铁的应用

Large Temperature Difference Air Conditioning Units at Low Temperature Applications in the Subway

本文总结了广州地铁大温差低温送风空调机组在节能评估,设计开发的经验,分析表冷器冷冻水初温、排数、迎风面积、管程、管径、肋片片型等对空调机组性能的影响,以及低温送风对空调机箱体的要求,提出了设计冷水大温差低温送风机组的设计要点。

Thispaper summarizes the large temperature difference between Guangzhou Metro low - temperature air conditioning unit in the energy assessment, design and development experience, analysis table cooler chilled water temperature in early and exclusive few, the wind area, tube diameter, fin- type movie on the performance of air conditioning units, as well as the cold air distribution of air - conditioning requirements of the body chassis, the design of cold water with huge temperature difference of cold air distribution unit design.
