Abstract
This report tells what the recent movement of urban redevelopment is, what electric power companies are doing for that, and what the district heating and cooling (D. H. C.) system with heat pumps is, especially in the water-front area in Tokyo.
Now the movement of urban redevelopment is spreading all over Japan with its first step in Tokyo. D. H. C. system is also in the limelight, because it has high energy conservation and good environmental preservation. Namely, D.H.C. system with heat pumps has high coefficients of performance (3-5) and discharges no pollutants (NOx and SOx), to keep urban environment clean and safe.
In this report D. H. C. system utilizing urban wasted heat is described, which provides heat in the water-front area in Tokyo. Example systems in Hikarigaoka Park Town and Shibaura 4-chome Distric where D.H.C. systems are in actual operation are also demonstrated.
