SOLAR AIR SYSTEM
The innovative and eligible solar air system LUBI Wall transforms the solar energy free of charge, into warm air for the efficient heating of halls.
Solar Air System for fresh air in summer and comfortable heat in winter
With the Solar Air System, the incoming air flows through the numerous perforations of the LUBI panels into the space between the panels and the building wall, whereby the wall itself operates as solar colector.
The solar-heated air is extracted and directed to the hall or the air supply system.

Working principle of solar air heating system
All grazed solar thermal collectors, whether it is for air or water heating, lose most of their heat through the front glazed surface. This can be felt when the glazing gets warm: in this case, the collector is losing heat to the environment.
The basic principle of the “Lubi Wall” system consist in reducing these heat losses to the environment to a minimum.
Solar radiation passes through the highly transmissive polycarbonate. Some heat is absorbed within the Lubi polycarbonate collector.
The solar radiation reaches the black wall. This wall now acts as a solar absorber. The absorber may happen to be the existing wall or the roof of the building, or a special underlayer. At this stage, solar radiation turns into heat.
The absorber heat is then trapped as hot air between the Lubi panels and the absorber. The air gap is called the collector’s “plenum”.
At optimal solar conditions, the air temperature within the plenum may reach up to 81ºF (45ºC) above the ambient temperature.
When the fan is turned on, the influx of outside air through the Lubi panels’ perforations cools the panels down continuously, preventing them from warming up. In this way, heat losses to the environment are reduced to an absolute minimum.
The solar-heated air is mechanically fed into the building’s ventilation system or process.
Therefore, the only place where solar heat can go is into the building or the process to be heated.
