摘要
针对地铁站在地面设置冷却塔的拆迁、环保等问题,在蒸发冷凝技术现状研究的基础上,结合地铁站内环境和土建布局的特点,提出风墙型直膨式蒸发冷凝空调系统在地铁站的应用方案,并以我国南方某城市的标准地下车站为例,与传统空调系统、机房型蒸发冷凝方案进行综合技术经济对比分析.结果表明,风墙型直膨式蒸发冷凝空调系统取消了地面冷却塔,空调系统COP虽有所降低,但在节约地下空间、降低车站投资、系统控制、运营维护等方面具有明显的技术经济优势.
Abstract
Based on the research on the current status of evaporative condensation technology and the characteristics of the internal environment and civil layout of subway stations,this paper proposes an application plan for the wind wall type direct expansion evaporative condensation air conditioning system in subway stations,addressing issues such as demolition and environmental protection of cooling towers installed on the ground.Taking a standard underground station in a city in southern China as an example,a comprehensive technical and economic comparison analysis is conducted with traditional air conditioning systems and machine room type evaporative condensation schemes.The results show that the wind wall type direct expansion evaporative condensation air conditioning system eliminates the ground cooling tower,and although the COP of the air conditioning system has been reduced,it has obvious technical and economic advantages in saving underground space,reducing station investment,system control,operation and maintenance,etc.
