太阳能排空双循环户用供热系统应用案例分析

本文以邢台市隆尧县某农村住宅采暖为例,对太阳能+电辅助清洁采暖系统设计、应用特点及运行效益进行分析。太阳能集热器吸收太阳能转化为热水的热能,通过热水循环泵和循环管路实现热水循环,地暖或暖气片等采暖末端实现户内采暖。系统具有自排空防冻功能,水箱安装在室内或封闭的设备间内,水箱内置不锈钢波纹盘管满足四季热水需求。

This paper takes a rural residential heating system in Longyao County of Xingtai City as an example to analyze the design,application characteristics and operating benefits of solar energy coupling electrically assisted clean heating system.The solar collector absorbs the solar energy and converts it into hot water heat energy,and the hot water circulation pump circulates water through pipelines.The heating ends,such as floor heating or radiator,realize indoor heating.The system has the function of self-emptying as well as anti-freezing.The water tank is installed indoors or in a closed equipment room and the internal stainless steel corrugated coils meet the demand of hot water in all seasons.
