针对阳台壁挂分体式太阳能热水系统,以太阳能保证率、经济性、用水舒适度和用水卫生状况为指标,比较分析了蓄热水箱电加热和用水终端燃气加热两种辅助加热模式对系统性能的影响,并在此基础上,提出了一种更为适宜的辅助加热运行模式。结果表明:相比较于蓄热水箱电加热模式,用水终端燃气加热模式的太阳能保证率提高了45.4%且年运行费用降低了40.73%;此外,用水终端燃气加热模式的出水温度稳定性更高,但其蓄热水箱存在滋生军团菌而影响用水卫生的隐患,建议定期在用水时段利用蓄水箱内置的电加热装置将水加热到60℃以确保水质卫生。
Aiming at the split solar hot water system on the balcony wall, taking the solar energy guarantee rate, economy, water comfort and sanitary status as the indexes, two auxiliary heating modes, electric heating and water terminal gas heating, were compared and analyzed. On this basis, a more suitable mode of auxiliary heating operation is proposed. The results show that compared with the electric heating mode of the heat storage water tank, the solar energy guarantee rate of the end gas heating mode is increased by 45.4% and the annual running cost is reduced by 40.73%. In addition, the stability of the water temperature of the terminal heating mode is higher , But its thermal storage tank breeding Legionella bacteria affect the health of the hidden dangers, it is recommended that regularly use water storage tank built-in electric heating device to heat the water to 60 ℃ to ensure water quality and hygiene.
