分析了天津市9个气象站60年的气象数据的演化特征,研究了气候变化因素影响下空调室外计算参数的变化特征,以期为气候变化影响下建筑节能设计参数的选取确定提供参考。结果表明:室外计算温度随着气候变暖而呈现出增加的趋势,夏季室外计算温度的增加幅度要低于冬季的计算温度;城市的热岛效应导致市区的室外计算温度明显高于郊区,并且越靠近城市,室外计算温度越高;随着气候的变暖,以干(湿)球温度来确定露点温度的分析计算方法有失偏颇。
分析瞭天津市9箇氣象站60年的氣象數據的縯化特徵,研究瞭氣候變化因素影響下空調室外計算參數的變化特徵,以期為氣候變化影響下建築節能設計參數的選取確定提供參攷。結果錶明:室外計算溫度隨著氣候變暖而呈現齣增加的趨勢,夏季室外計算溫度的增加幅度要低于鼕季的計算溫度;城市的熱島效應導緻市區的室外計算溫度明顯高于郊區,併且越靠近城市,室外計算溫度越高;隨著氣候的變暖,以榦(濕)毬溫度來確定露點溫度的分析計算方法有失偏頗。

Based on the meteorological data for 60 years from nine stations in Tianjin, the evolution characteristics are analyzed, and various characteristics of air conditioner outdoor calculated parameters in-fluenced by climate change are studied. It can provide reference for the selection of design parameters of building energy conservation to determine under the influence of climate change. The results show that the outdoor design temperature will increase with the climate warming, and the increasing degree in summer is lower than the calculated temperature in winter. The calculated outdoor temperature in the city is signifi-cantly higher than that in the suburbs caused by the urban heat island effect; and closer to the city, higher the outdoor temperature is calculated. The method of analysis and calculation of dry (wet) bulb temperature to determine the dew point temperature is biased as the climate warming.
