A Study of District Heating and Cooling Considerating the Climate of Japan

本研究的目的是掌握日本各地能源需求的气候差异特点，探讨未利用能源和热电联产的利用方式。首先，对日本北海道、东京和日本西部地区的分布式热电联产设施进行了调研，掌握了该地区的特点。根据这项调查，北海道地区的热负荷密度最高，日本西部地区的冷负荷密度最高。我们提出了利用太阳能、未利用的河流能源和热电联产的新能源供应系统。并考察了札幌、东京和福冈地区引入该系统的效果。因此，福冈地区在引入未使用的能源方面是最好的，因为福冈支持日照时间和水温。但在其他领域也被证明是成功的。因此，在日本各地开发利用闲置能源的DHC是非常有效的。

The purpose of this study is grasping the characteristics of energy demand depends on defference of the climate in all parts of Japan and examining the methods of utilizing unused energy and co-generation.First, we surveyed the facilities of DHC in Hokkaido, Tokyo and west Japan area, and grasped the district characteristics. According to this survey, the heating load density is highest in Hokkaido area, and the cooling load density is highest in west Japan area.We proposaled new energy supply system, utilizing solar energy, unused river energy and co-generation. And examined the effects of introducing systems into Sapporo, Tokyo and Fukuoka area. As a consequence, Fukuoka area was best in introducing unused energy because Fukuoka is in favor of the hours of daylight and water temperature. But also proved to be successful in other area. So exermining DHC of utilizing unused energy in all parts of Japan is very effective.
