Working Principle:

This model uses the all-glass evacuatedsolar collector tubes as the heat-absorbing element. The high vacuum degree of theclearance between the outer and the inner tube reduces the heat emission whichis caused by convection and conduction the layer films of the all glassevacuated tubes transfer the sun energy into heat energy the high absorptionand low emittance rate of Rongchang’s layer films is unique, depending on thedifferent density between hot water and cold water, a water flowing cycle iscreated in the tube, hot water flows automatically upwards while the cold waterflows downward and the water in the storage tank will be heated from thisnatural circulation.
