摘要
通过试验研究蓄热水箱,分别测量0.75 m和1.5 m螺旋盘管一天中进出水温度和流量等参数,对比分析二者制热量、耗功量、COP。结果表明,蓄热水箱采用0.75 m螺旋盘管系统COP低于采用1.5 m螺旋盘管系统COP。基于TRNSYS模拟软件,对太阳能集热器与空气源热泵采用串联和并联两种连接方式下的太阳能-空气源热泵系统全年运行下的制热量、耗功量、COP进行研究可知,采用并联方式连接的逐月系统制热量高于串联方式的系统制热量,4月—9月并联系统的耗功量低于串联系统的耗功量;5月时两种连接方式系统COP差距最大,2月时两种连接方式的系统COP差距最小。
The existing 0.75 m and 1.5 m long spiral coil heat exchange tank,experimental records of inlet and outlet water temperature and flow rate and other parameters.The heat production,power consumption and COP of the two were compared and analyzed.The results show that the COP of 0.75 m spiral coil system is lower than that of 1.5 m spiral coil system.Based on the TRNSYS simulation software,the heating capacity,power consumption and COP of the solar air source heat pump system with series and parallel connection of solar collector and air source heat pump are studied.It can be seen that the monthly heating capacity of the system with parallel connection is higher than that of the system with series connection,from April to September,the power consumption of parallel system is lower than that of series system.The COP difference between the two connection modes was the largest in May,and the COP difference between the two connection modes was the smallest in February.
