太阳能主动式供热采暖技术在欧洲等发达国家应用已有二十多年历史,到2005年约800万m~2太阳能集热器用于采暖系统,约占集热器总量的20%,每年新建太阳能采暖系统约12万个。近几年我国开展了主动式太阳能供热采暖系统研究和示范,2004年,北京市平谷区在新农村建设中,启动了平谷区 Solar active heating technology has been used in developed countries such as Europe for more than 20 years. By 2005, about 8 million m 2 solar collectors will be used in heating systems, accounting for about 20% of the total heat collectors. Each year About 120,000 new solar heating systems. In recent years, China launched an active solar heating heating system research and demonstration. In 2004, Pinggu District of Beijing in the new rural construction, started the Pinggu District
