Second-exchange solar collectors
It is a kind of non-pressure solar collectors, water circulating inside the vacuum glass tubes, open circulating, but pressure system finally.
Better for commercial projects, such as big solar water heating systems for factories, hotel, school, swimming pool.
Working Principle
The hot water in the inner tank of manifold heats the water following through the heat-exchange pipe.
The heated water in the heat-exchange pipe is delivered to the water tank, thus completes the circulating
Economic styles, best used for good solar energy markets. |
