Pressurized Flat Plate Solar Collector

date:2020-08-04 16:24viewed:

Working Principle:

The absorber board absorbs solar radiation and converts it into thermo energy, and heat up the riser pipes inside flat plate solar collector. The cold water or heat transfer medium is heated when it flows through the riser pipes, and then it flows into water tank or tank jacket or copper coil in tank. The water temperature goes up gradually through the circulation between water tank and solar collector.
