基于實測與問卷調研的高溫天地鐵車站空氣運行溫度優化
Optimization of air operating temperature in subway stations in high temperature days based on actual measurement and questionnaire
摘要：
提出了高溫天基于相對熱指標（RWI）確定地鐵車站空氣運行溫度的方法。在上海市某地鐵車站現場測試熱環境參數，同時同步在車站站廳及站臺發放熱舒適調研問卷，選取乘客熱感覺為舒適的問卷，根據室外與站廳、站廳與站臺RWI差值的最小值來確定站廳及站臺的推薦空氣運行溫度。結果表明：在車站相對濕度為40%～70%的條件下，當室外溫度為35.0～36.0 ℃時，站廳及站臺推薦空氣運行溫度分別可達到32.6、31.1 ℃；當室外溫度為36.0～37.0 ℃時，站廳及站臺推薦空氣運行溫度分別可達到33.3、31.9 ℃。本文推薦的車站空氣運行溫度滿足乘客從室外進入站廳、站廳進入站臺“短暫舒適”的需求，同時較高車站空氣運行溫度對空調系統的節能意義重大。
Abstract：
This paper presents a method for calculating the air operating temperature of subway stations based on the relative warmth index (RWI) in high temperature days. While testing the thermal environment parameters in a subway station in Shanghai, the thermal comfort survey questionnaires are simultaneously distributed in the station hall and platform. The questionnaires with comfortable thermal sensation are selected to determine the recommended air operating temperatures of the station hall and platform according to the minimum difference of RWI between the outdoor and the station hall, and between the station hall and the platform. The results show that when the relative humidity of the station is 40% to 70%, the recommended air operating temperature of the station hall and platform can reach 32.6 ℃ and 31.1 ℃ respectively when the outdoor temperature is 35.0 ℃ to 36.0 ℃, and 33.3 ℃ and 31.9 ℃ respectively when the outdoor temperature is 36.0 ℃ to 37.0 ℃. This article recommends that the air operating temperature of the station meets the needs of passengers entering the station hall from the outside and entering the station platform from the station hall for “short-term comfort”. At the same time, higher station air operating temperature is of great significance to the energy saving of the air conditioning system.
