Abstract
We are developing a co-generation system for apartment buildings (Neighboring Co-Generation: NCG). The key concept of this system is to install a heat accumulator with a hot water supply and a room heating function at each household and to connect different households with single loop of heat transfer line. As a result, time leveling of the heat supply and heat transferring among households become possible. Thus, the costs of the piping and the heat source equipment decreases. The former conference 2006 we reported heat accumulator with normal pressure tank of hot water for space heating. In this paper, we reported the evaluation of this NCG under demands of living conditions in apartment buildings.
