Abstract

This study aimed to understand regional heat discharge by means of thermal system analysis that considered the ratio of cooling heat source devices derived from a completed database of building equipment. The results showed a clear relationship between floor space and the ratio of latent heat to total heat released from air conditioning systems and related devices. This may have been due to the effect of cooling towers, which are mainly used in large buildings. The total amount of sensible heat released from air conditioning systems and related devices in the 23 wards of Tokyo was estimated using the GIS database of floor spaces. The results showed that summertime sensible heat in the 23 wards of Tokyo reached 13-14GW in the daytime, and 180GW・h per day. In addition, latent heat that was released from air conditioning systems and related devices in the 23 wards of Tokyo accounted for 25-28% of total daytime heat in the summer.
