选用1961-2020 年上海市10 个国家气象站观测资料,计算该地区冬季室外空调不同气象参数下的空调热负荷变化,结合碳排放因子法,基于2020 年数据量化分析上海市冬季气象条件变化对空调热负荷和碳排放量的影响.结果表明:上海市冬季空调室外计算气温明显升高,计算相对湿度变化以减小为主,其中中心城区的计算气温和相对湿度变幅最大,上海东北部的崇明区最小.综合空调室外计算气温和相对湿度变化,上海市冬季空调热负荷总量为减小趋势.与 1961-1990 年相比,1991-2020 年总热负荷减小5.39%～8.42%.上海市冬季空调碳排放受气候变化影响可减少55～4553 t.
Changes in outdoor calculated meteorological parameters of air-conditioning in winter and effects on air-conditioning heat load and carbon emissions in Shanghai,1961-2020
Observations from 10 national meteorological stations in Shanghai from 1961 to 2020 were used to cal-culate the changes in heat loads under different meteorological parameters for outdoor air-conditioning in winter.Combined with the carbon emission factor method,the impacts of changes in meteorological conditions on air-con-ditioning heat loads and carbon emissions in winter in Shanghai were quantified and analyzed based on the 2020 data The results show that the calculated outdoor air temperature of air conditioning in winter in Shanghai increases significantly,and the change of calculated relative humidity mainly decreases,with the largest variation of calculat-ed air temperature and relative humidity in the central urban area,and the smallest in Chongming District in the northeastern part of Shanghai.Comprehensive air conditioning outdoor calculated temperature and relative humidity changes,the total air conditioning heat load in Shanghai in winter is a decreasing trend.Compared with 1961-1990,the total heat load decreases by 5.39%to 8.42%from 1991 to 2020.The carbon emission from air conditioning in winter in Shanghai can be reduced by about 55-4553 t by climate change.
