针对一个具体实例,设计了一个利用燃气大锅灶烟气余热与直热式空气源热泵热水器联合供热水系统,提出了一种利用大锅灶烟气余热为直热式空气源热泵热水器除霜的方法,研究了大锅灶余热深度回收的方案。在设计工况下,该系统可节能19.5%,可以提高天然气热能利用率28%。

For a specific example,a combined heating water system using flue gas waste heat of large gas stove and direct heat air source heat pump water heater was designed,a defrosting method using flue gas waste heat of large gas stove as air source heat pump water heater was proposed,and a deep recovery scheme of waste heat of large gas stove was studied.Under design conditions,the system can save 19.5%energy and in...
