摘要
增加供热时间及供应生活热水成为供热企业提高经济效益的途径,但对于以区域供热锅炉房或热电厂为集中供热热源的供热系统,会造成较大的热损失及产生较强的交变热应力冲击。引入太阳能热源系统与集中供热热源联合供热是实现增加供热时间及供应生活热水的有效方法。介绍了太阳能热源系统的关键装置———全天候真空集热管,阐述了联合供热系统的组成及其运行调节过程。
The extension of heating period and supply of domestic hot water are a way to improve the economic benefit of heating enterprises, but more heat loss may be caused and stronger alternating thermal stress shock may be produced in the heating system using district heating boiler room or heat and power plant as heat source of centralized heat-supply system. The combined heating with solar heat source and heat source of centralized heat-supply system is an effective method to fulfill the extension of heating period and supply of domestic hot water. The key device of solar heat source system, namely all-weather vacuum heat collecting pipe is introduced. The composition of the combined heating system and its opera- tion and adjustment process are described.
