介绍了在社区系统中使用太阳能和储能的几个例子（瑞典Lyckebo，芬兰Kerava），在区域供暖和制冷（DHC）中使用天然气（芬兰拉彭兰塔和拉赫蒂），以及在DHC中使用热泵的应用（瑞典乌普萨拉废水和斯德哥尔摩预热系统）。在废物处理和DHC系统的未来发展中，对几种来自生物质、回收和其他可能技术的替代燃料进行了一些预测。简要讨论了美国和世界其他地方的环境问题和立法发展。关键词:1996年，能源，生物量，回收，区域供暖，区域制冷，太阳能，储能，芬兰，瑞典，丹麦，德国，地热能，天然气，美国，立法，废水，热电联产引用:研讨会，ASHRAE Trans。 1996年，第102卷，第2部分

Describes a few examples of the use of solar energy and energy storage in community-wide systems (Lyckebo, Sweden, Kerava, Finland), the use of natural gas in district heating and cooling (DHC) (Lappenranta and Lahti, Finland), and applications of heat pump utilisation in DHC (Uppsala waste water and Stockholm preheat system in Sweden). Some projections are made of several alternative fuels derived from biomass, recycling, and other possible technologies in the future development of waste-handling and DHC systems. A brief discussion is included regarding the environmental concerns and legislative development in the US and elsewhere in the world.KEYWORDS: year 1996, energy sources, biomass, recycling, district heating, district cooling, solar energy, energy storage, Finland, Sweden, Denmark, Germany, geothermal energy, natural gas, USA, legislation, waste water, combined heat and power
