In order for economically viable distributed generation systems for local community to spread, it is essential to develop an efficient and low-cost heat supply system. We have proposed a new heat supply system presented at ICOPE-03 Kobe and ICOPE-05 Chicago. The key technology for the system is to connect compact heat supply units installed in all the households of the local community, such as a condominium, by a single loop of hot water piping. Phase change material such as paraffin was used for a heat supply unit as heat storage material. However we have developed a new heat supply unit made of plastic water tank for ease to use and a serious cost reduction. Hot water for space heating is used as heat storage material. Some experiments for a heat supply unit and dynamic simulations for heat demand have been conducted, such as heat storage and supply of the heat supply unit, and COP evaluation of a new CO_2 heat pump system using low- temperature exhaust gas. In this paper, experimental results on the performance of the new heat supply system installed to 7 households in condominium, and evaluation of dynamic simulation for 50 households using 1B hot water piping are presented.
