Air Solar collectors cost



New air collector concept


Low Cost

Good Performance

Flexibility

Lightness

Simplicity


Simplicity


Air as heat transferring agent does not freeze, does not boil, does not oxidize and has not problem of leakage

Air systems already installed in buildings Air-handling, filtered, driving and forced ventilation

Fresh air regulations for buildings ventilation (EN 13779-2005, CEN/TR 14788) and energy (CEN/TR 14788)

Simplicity


The aim is to simplify the construction to reduce material costs and installation.

Minimal design SilhouetteClassical eyeglass frame

New Air Collector concept

Simplicity


The façade is the structure system

This reduces support material and makes easier the installation.

Simplicity


Connect outside with air-handling system

Just a drill in façade for all the system

Simplicity


Quick collector installation

Modular-based lightweight installation kits.

Simplicity


How does the system work? Winter operation

Take air convection.External wall insulation.

Simplicity


Summer operation

It works as a ventilated façade.External wall insulation.

Simplicity


Flexibility of adaptation


Wall with windows and obstacles


Realistic façade.Preferably south facing.


Minimum installation 3 modules


Good performance.Just a drill in facade.


Installation 5 modules


Building Integrated.Just a drill in facade.


Installation 10 modules


Building Integrated.Two drills in facade.


Big installation


Building Integrated. Horizontal and vertical growth.


Lightness and functionality


High impact resistance 250 times more than glass

We continue to improve


improvements identified

Performance on cloudy days

Increase efficiency of diffuse solar radiation

Performance on very cold days

Fresh air setting without efficiency loss



The efficiency of a solar collector is highest when the ambient temperature is cold.

Air return



But on cold, cloudy days there may be insufficient energy to achieve this. We can recirculate a part of inside air to increase the temperature.

Air return



Increase of absorber surface


The efficiency of a solar collector increases with more surface absorber
