The AP solar collector comprises three main parts:
2.Evacuated Tube (ET)
Absorbs solar energy and converts it to usable heat. Vacuum between the two glass layers insulates against heat loss.
3.Heat Pipe (HP)
Copper vacuum pipe that transfers the heat from within the ET up to the manifold.
Insulated box containing the copper header pipe. The header is pair of contoured copper pipes with dry connect sockets that the heat pipes plug into.
Strong and easy to install with various options to match different mounting methods.
Step 1: The absorber coating on the inner glass tube absorbs sunlight and converts it into heat.
Step 2: Steam forms inside heat pipe which transfers heat rapidly up to the manifold.
Step 3: A pump circulates water or heat transfer fluid through the header pipe, carrying heat back to the storage tank. Gradually throughout the day the tank is heated up.
The instantaneous efficiency level depends on the surface area used for the calculation. It is important to use the same area (absorber, aperture or gross) when comparing collectors. Aperture is the standard area measurement for presenting efficiency values.
