The light-colored, white or ivory, rarely is recommended for absorbers of solar collectors more. However, the recent development of solar technology with patented perforated solar air heating solar wall glass makes it possible without having to bear the costs of dark paint or alter the aesthetics of the building of 26,000 square meters of outdoor. The solar air heater is closer to a wall of Windows in a solar collector to Plastech, a Sherbrooke, Quebec division of the Group of integration of my supplied interior molded by injection and sealing for automotive parts.

 

Lubi Plastech wall heating solar air, manufactured by Enerconcept technologies, has a power of 80.7 efficiency by the Canadian Standards Association. On a black surface, the Lubi is 20 percent more efficient than other nominal wall solar glass or metal collectors. In a white wall such as Plastechs, however, the Lubi is 58 per cent more efficient.

 

With darker colors, the collector can provide the temperature of the air to 81 degrees F (45 degrees C) above ambient outdoor and maximum outputs of 254 BTU/h/ft2 (800 watts/m2). Since its installation in Plastech closure system services by the end of 2010, an increase in temperature of 45 degrees F (25 degrees C) was measured in the sunny days, a performance that was previously unknown in the solar industry for a white collector. Performance statistics Lubi are certified by the center of national Solar test (NSTF), a Mississauga, Ont laboratory. based third tests and solar technologies in the rates of temperature control / solar / wind and is sanctioned by the Solar Rating and certification Corp. (SRRC).

"For Plastech, solar air heater has been a good way to reduce energy costs and CO2 emissions, preserve the environment and the maintenance of a comfortable workplace for our employees," said Stéphane Tremblay, general manager of Plastech.

 

With walls dark as absorbent is recommended for efficiency optimal solar performance, however, the inherent disadvantages of performance of light color Plastech wall were compensated with a 40 percent larger collector. After incentives of natural resources Canada and a discount of the Fund of energy efficiency (EPS) of the company's natural gas, Gaz Metro, the recovery of the investment in the project is four years. In addition to $6,000 in annual savings, the manifold reduces emissions of CO2 in a 15 Plastech tons / year.

How does the system work?

 

Installed by Sherbrooke, Quebec based on metal contractor RTSI, 90 x 24 meters high wall solar collector has crystal clear that from afar looks like Windows. The Sun radiates through the glazing, where it is absorbed through the wall of the building of corrugated steel. The efficiency of the Lubi is attributed to its patented design with 906 holes by 3 x 1 meters long (900 x 320 mm) Panel. As the indoor fan collected draws hot air through the collector of six inches deep, ambient air is based through the holes and cooling panels. Unlike other mounted on the wall solar collectors who suffer the loss of heat through the significant glazing or metal facade, the cooling of the air flow panel minimizes heat loss and increases efficiency.
