Flat Plate Solar Collector KD-SC-FP

Working principle:
Flat Plate Solar Collector is the key part of the flat plate solar water heater. It consists of absorber, cover glass, insulation, and shell. The metal absorbing plate with coating is welded on the red copper pipe. The cold water or the medium liquid is heated when running through the pipe. The transparent cover glass allows visible light to pass through and blocks the the far infrared. It means the sunlight can pass the cover glass and reaches the absorber to produce heat, but the far infrared resulted from the radiation of heated absorber is blocked and kept inside. In this way, the heat loss is reduced. And the heat-absorbing efficiency and the temperature of the absorber can be increased. There are usually three kinds of coatings: black selective coating, black chrome coating and blue tinox titanium coating. In areas with winter temperature above 0 ℃, system of direct-heating of cold water is applicable, but in areas with winter temperature below 0 ℃, the user could input medium liquid in the system to heat cold water indirectly as an alternative.
