摘　　要：在昆明地区晴好天气条件下,对一种新型横双排全玻璃真空管太阳能热水器进行单天及连续多天的热性能实验.实验结果表明,新型太阳能热水器的单天日有用得热量偏低,为5.17 MJ/m^(2),但保温性能良好;新型太阳能热水器水箱温度分层比普通太阳能热水器明显,连续多天实验条件下各层水温变化有所不同;增大南北向集热倾角后,北向水温均高于南向.The thermal performance of a new horizontal double-row all-glass evacuated tubes solar water heater is tested under one day and multi-day with sunny day test conditions in Kunming.The results show that the daily useful heat gain of the new solar water heater is low at 5.17 MJ/m^(2),but the thermal insulation performance is good.The water temperature stratification in the new solar water heater tank is more obvious than that of the common solar water heater,and the temperature changes at each layer in the tank are different under the multi-day experimental conditions.The temperature in the north of the tank is higher than that in the south after the tilt angle of the collector increased.
