摘　　要：按不同的使用时间分别抽取郑州在用全玻璃真空太阳热水器真空集热管,通过对水垢厚度和热性能进行测试,结果表明,全玻璃真空太阳热水器,在使用的前24个月内,水垢厚度生成比较快,超过24个月,水垢生成速度减缓;全玻璃真空太阳热水器在使用18个月后应进行除垢,以恢复全玻璃真空太阳集热管的吸热性能.这项研究为全玻璃真空太阳热水器使用及保养提供了有益的参考.　From the thickness and thermal performance tests on the all-glass evacuated solar collector tubes sampled from Zhengzhou city with disparate duration.The results show that for all-glass evacuated solar collector tube the forming speed of the incrustation scale is higher in the first 24 months.The speed will decrease 24 months later.And the incrustation scale in the all-glass evacuated solar collector tubes should be cleaned up after 18 months of use to recover their heat absorbing performance.The study will provide favorable reference for the maintenance of the all-glass evacuated solar water heater after sale.
