Research on the Application of Wind Wall Type Direct Expansion Evaporative Condensation Air Conditioning System in Subway Stations
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.
