Working Principle

1) Vacuum tube is composed of inner and outer glass pipe, inspiratory layer, vacuum space, inspriatory membrane. The surface of inner and outer glass tube is plated with selective absorption layer. The layer absorb the solar energy and turn it into heat energy, aluminum fins pass the heat energy to the heat pipe, the liquid medium in the heat pipe is heated by the heat energy, then turns into the gas medium, the gas medium flows up to the top of the heat pipe (condenser) and transfer the energy to the copper manifold header heat pipe. At the same time the gas medium turns into the liquid when cooled, then flows down. Keep recycling.

 

2) An electronic controller measures the temperature of the solar collector and the water in the bottom of the storage tank. If the collector is hotter, meaning there is heat available. The controller supplies power to a circulation pump which pushes liquid which in circulation system circulating. The heat will transferred to storage tank via the liquid.

 

The typical household uses 10,000 to 15,000 BTUs of hot water per person per day. A 20 vacuum tube solar collector can produce 30,000 BTUs on a summer day with a footprint on a roof of only 36 square feet. The system can provide 100% of summer hot water ...
