nanoSUN

The experimental and innovative solar energy collector system integrated into the ventilated façades of buildings, playing a significant role in the air conditioning and ventilation of living spaces. The main features and benefits of the system include:

Preheating of Fresh Air in Cold Seasons: During daytime in colder seasons, outdoor air is preheated as it passes through perforated plates. This process is augmented by phase change materials enhanced with nanomaterials (nePCM), which store excess heat. Consequently, the warm air is directed indoors, ensuring the fresh air.

Minimization of Heat Loss During Nighttime: The retractable thermal insulation system is automatically extended at night during the cold season to reduce heat loss to the exterior. This allows only the fresh outdoor air to be heated, optimizing energy efficiency.

Introduction of Pre-warmed Fresh Air at Night in Warm Seasons: Depending on needs, pre-warmed fresh air is introduced indoors at night during the warm season. The retractable thermal insulation system is complemented by a thermal insulating structure made from high energy efficiency sandwich panels.

Through the replacement or reducing of the main air pollutants within living spaces, this system ensures occupants' comfort and health while following the strict fresh air ventilation regulations of the European Union. It is an example of a cutting-edge approach to benefiting from environmental conditions consistently.
