Heating with the power of the Sun – Solar air collectors themselves build currently on the market available solar air collectors are still very expensive relative to the collector. So are the payback periods in the range of 15-20 years. Trubadu.de solar air collectors since 2008 for the construction of the self. The self construction air collectors work very effectively, are simple in design and can be combined well with existing heating systems. Solar air collectors thus directly contribute to the saving of energy, work independently and can be easily retrofitted to almost every building.
The air collector used as a medium of air, which is heated and blown by fans directly in the rooms to be heated in the collector. Compared to the hot water collector, an air collector respond faster to changing irradiation conditions and works very effectively in the cold season. Efficiencies of 50-70% are the rule, the air flow rate of the projects presented by Trubadu.de is up to 250 m/h. In new and thus almost airtight, well insulated buildings contribute the air collectors to improve the room climate. The required air change rates are thus due to the supply by means of fresh preheated air reached – CO2 critical values for residential building significantly exceeded. A combination with a controlled load and ventilation systems, as well as an air to air heat pump are possible and increase its efficiency.
Combined with the unique in Germany Trubadu air storage in PCM memory boards so far day surplus quantities for the night can be saved and thus ensures a pleasant room climate. Trubadu.de presents four air collectors and a PCM air space to the replica. Meanwhile, over 2,000 customers building instructions for the various reconstruction projects have acquired. 95% of them come from Germany, the remaining 5% are spread all over the world. Interesting reference projects are the heating of an Iraqi school, as well as a yurt in the Mongolia. In Indonesia, a reconstruction project is used to dry tea leaves and in Sweden for the venting of holiday homes. Due to the air collector Kit S-line is developed the experience that a not inconsiderable number of projects does not come to realize since the procurement constitutes a not inconsiderable amount of time, 2011. All parts are available and included in the Kit. The replica is very easy and estimated no more than 4-6 hours of work. With a low-cost air collector Kit Trubadu.de occupies a market niche and thus contributes to a wider dissemination of the air collector in Germany.
