摘要:
Summer sol–air temperature (tsa) is a basic parameter required for building cooling load calculation, which is a comprehensive performance of heat radiation and outdoor air temperature. And the value is determined by the total heat transfer coefficient (αw) on the wall exterior surface. The code for thermal design of China stipulates that αw equals 19 W/m2·, which ignores the correction on convective heat transfer coefficient (αc) affected by prevalent wind speed in different climate zones and the evaporation heat transfer coefficient (αv) caused by rainfall. To address this issue, a case study was conducted on an island building in China. The value of αc at high wind speed (4.2 m/s) was corrected, and the hourly value of αv on the humid wall surface was supplemented. The results show that due to the correction of αw, tsa decreases by an average of 3.35 on the vertical and 8.34 on the horizontal. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
