solar collector of solar water heater

Description

1) working principle of high pressure solar heater:it utilizes the alternative absorption coating on the inner surface of the vacuum tube, from the high-temperature environment super-conduction tubes, leads the heat to the water tank, and produces hot water, 2)Easy to use and convenient to install, 3) can be put in the courttard, on the roof or balcony, 4)inlet water hole connects to the tap water, and the outlet hole connects to the tap water, and the outlet hole produces pressure hot water directly, 5) working principle of low pressure solar heate: it adopts the alternative absorption coating absorb the solar energy, heat the water in the vacuum tube directly, through the cold and hot water convection, changes the solar energy into heat energy to store in the water tank: a)adopts the double-deck highly special hard glass tube of boron silicon b)double-deck glass coaxical structure, intermediate layer releases the vacuum, maintains 5X***2Pa high vacuum for a long time while in charge c)Magnetism accuse of alternative absorption coating, AL/N/AL of sputter aluminum nitrogen aluminum alternative absorptation coating solar radition absorption rate>*2%, and hot emittance<7%, d)long performance life: *5 years e)Endures climate feature:thermal effiency is goos in the whole year, Specification; 1) inner manifold:stainless steel SUS**4 2b, 2) outer manifold: VPDF 3)glass tube dimension:*7X***0 mm 4)heat preservation: *2 hours 5) hail resistance:*5mm
