Abstract

Abstract:

Observations from 10 national meteorological stations in Shanghai from 1961 to 2020 were used to calculate 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-conditioning 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 calculated 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.
