The Transition of Air-Conditioning Equipments and the Presumption of the Change on Urban Heat Environment Load

Abstract

Data base of air-conditioning systems used in Japan was prepared to examine the influence of air-conditioning waste heat given on urban thermal environment. By using this data base, the time series transition of heat source equipment, heat discharge methods, and equipment capacities etc. was discussed. Moreover, the amount of waste heat from air conditioning systems in Osaka city area was estimated about 1977, 1985 and 1993 respectively and the distribution of sensible waste heat was also estimated.
