摘　　要：本文对城市轨道交通的空调系统目前应用的7℃~12℃冷冻水供回水温度方案所导致的空调器出风参数及室内环境参数难以保证、冷水机组及系统能效难以提升的问题进行了深入的研究。在此基础上,提出了城市轨道交通地下车站空调系统采用11℃~16℃的空调供回水温度方案。并通过模拟仿真计算及实际工程验证了该方案可有效保证出风温度、实际制冷量、室内空气参数与设计要求的匹配性。同时,该方案令冷水机组及系统能效比提升明显,具有显著的节能效果。This paper makes an in-depth study on the problems that the outlet air parameters and indoor environmental parameters of air conditioner are difficult to guarantee and the energy efficiency of chiller and system is difficult to improve due to the 7~12℃chilled water supply and return water temperature scheme currently applied in the air conditioning system of urban rail transit.On this basis,the scheme of 11~16℃air conditioning supply and return water temperature for the air conditioning system of urban rail transit underground station is proposed.Through simulation calculation and practical engineering,it is verified that the scheme can effectively ensure the matching of air outlet temperature,actual refrigeration capacity,indoor air parameters and design requirements.At the same time,the scheme can significantly improve the energy efficiency ratio of chiller and system,and has significant energy-saving effect.
