Abstract
This study quantifies the proportion of anthropogenic heat and convective heat from a building by using a numerical simulation system. The numerical simulation system consists of external heat balance simulation, building heat load simulation, air-conditioning energy simulation and anthropogenic heat simulation. As the results of the numerical simulation for a 12 story-building with an absorption refrigerator and cooling tower, it is shown that latent heat release occupies large part of the anthropogenic heat and the amount of sensible heat released by convection occupies approximately 80% of the atmospheric heat load by sensible heat. By changing the air-conditioning system to the system with an air-cooled heat pump chiller, the atmospheric heat load by sensible heat increases to 2.1 times and the sensible heat from the air-conditioning system becomes two times larger than the sensible heat by convection. .
