250L Compact Pressurized Evacuated Tube Integrated Solar Water
Heater for Home
Working Principle:
Compact Pressurized Solar Water Heaters are all-glass evacuated
tube solar domestic water systems combined with heat pipes inside
the glass tube. The selective coating on the inner tube converts
solar energy into heat energy and transfers to the heat pipe by an
aluminum fin. The liquid in the heat pipe changes into vapor which
rises to the condenser. The heat conducts the water inside the tank
and the vapor becomes liquid, returning to the base of the heat
pipe. This continuous circulation transfers heat from the heat pipe
to the cold water in the tank as long as sun is heating the
collectors. Hot water can be obtained by injecting cold water from
the bottom of the tank.
