Working principle of low pressure solar heater
adopt the alternative absorption coating to absorb the solar energy,
heat the water in the vacuum tube directly, through the cold hot water convection.
change 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 coaxial structure, intermediate layer releases the vacuum, maintains 5 x 10-2Pa 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 absorption coating solar radiation absorption rate ≥93%, and hot emittance ≤6%.
d) Long performance life: 15 years.
e) Endures climate feature: thermal efficiency is good in the whole year.
