Solar Thermal Active Air Heating

From solar pool heating systems to solar water heating systems active solar energy is a cost effective way for homeowners to take advantage of solar energy this solar energy technology is called active because you are actively gathering and using energy from the sun for your solar home heating needs.

Solar thermal active air heating. A trombe wall is a passive solar heating and ventilation system consisting of an air channel sandwiched between a window and a sun facing thermal mass. Active solar heating works under the same basic principle as passive solar. The system provides 1500 watts equivalent heating capacity and since it comes ready to mount out of the box its designed for the diy installer. Solar thermal collectors are either non concentrating or concentrating.

Some provide a contribution towards space heating for example by pre heating air for a warm air central heating system or contain specially designed collectors in a solar wall. Active solar heating uses the hot rays of the sun to heat water or air which is them moved inside the building warming up the interior. That s where active solar comes in. Active solar air heating systems a more recent development use fans to draw in circulate and exhaust air.

However that s about the end of their similarity. Active solar heating systems use solar energy to heat a fluid either liquid or air and then transfer the solar heat directly to the interior space or to a storage system for later use. A pv panel powers the air circulation fan which is controlled by a simple thermostat in the conditioned space. The major difference between the two is that an active solar system has an active element which moves the heat from the collector and absorber to the thermal mass or.

If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat. The arctica solar 1500 series heater is a very unique stand alone solar air heater. During the heating cycle the trombe wall radiates stored heat. The perforated cladding system figure 1 is a bare plate solar collector that uses fans to draw air through thousands of tiny holes in a layer of unglazed dark metal plating which acts as the solar absorber.

The heat could be used to heat up a thermal mass inside the building so that even when it is cloudy the mass.
