ENERGY EVALUATION OF THE WIDE AREA HEAT SUPPLY SYSTEM WITH COMBINED HEAT AND POWER PLANT IN JAPAN

摘要

The District Heating and Cooling (DHC) system using the urban heat such as the exhaust heat from the waste incineration plants is expected becoming widespread and developing. The construction of the Wide area Heat Supply System with Combined Heat and Power (CHP) Plants which is seen in Europe is helpful for becoming widespread of DHC and for saving energy. So in this study, energy evaluation of the Wide Area Heat Supply System with CHP was done by the comparison with Heat Pump (HP) system. 1.Relations between the quantity of heat from the power plant can be supplied, and the decrease quantity of the generating electricity output by the heat supply were explained. 2.A difference in the carriage power by the temperature of heat medium was explained. 3.The energy evaluation of this system wad done by the comparison with the Heat Pump system. 4.Cooling heat ratio was taken in the index, and the coming into existence condition of the system was explained.
