Calculation method for the effect of heat rejection of split-type air conditioner on thermal environment and building energy demand for neighbourhood-level

The purpose of this research is to propose a simple and fast method evaluate the effect heat rejection split-type air conditioner on thermal environment surrounding building cooling demand provide guidance for architectural design in urban planning stage. In paper, we first determined factors that affect or are affected by as dissipation, wind speed, ambient temperature, which inputs CFD build regression model temperature rise. Then, coupled with energy consumption simulation software EnergyPlus estimate increase. result taking typical residential reference show maximum rise increase values 1.86°C 17%.
