Solutions

 One idea, many solutions

The goal of the freescoo concept is to maximize the use of solar thermal energy at low temperature (55-60°C) as energetic source for HVAC systems.  Freescoo is the ideal solution for those who have already invested in solar thermal systems or intend to invest in NZEB buildings by having available the necessary low grade solar thermal energy at 55°C to feed the process. Nevertheless, Freescoo can be also integrated even with alternative heat sources (heat pumps and boilers).

Compact facade system

This system offers the possibility to provide cooled, dehumidified or preheated air to the building with the necessary air change.

It is suitable for residential users or service sectors that require low flow of air treatment.

The system can be powered by liquid solar thermal or from any other heat source also operating at low temperature (50-60 ° C).

Can be installed on the external walls of the building.

In case of new buildings or in case of more serious renovations, the unit can also be installed directly into the structure of the wall.

Freescoo facade unit can be installed in a remote position from the solar collectors.

Air handling units

The system provides a complete air treatment and cover the needs of ventilation and air change.

It is suitable for users requiring a treatment of an air flow > 1000 m3/h

The unit can be powered by solar thermal or by any other heat source also operating at low temperature (50-60 ° C).

For the integration of the heat in the winter season, the system can be connected to any source of heat also operating at low temperature (40-50 ° C).

Installable on the roof of the building or on other suitable surface reached by solar radiation. The air handling unit can be installed in a remote position from the solar collectors.

Example of freescoo facade system configuration

 

freescoo plant

Every common solar thermal plant used for domestic hot water preparation can be adapted to power a freescoo unit, normally adding one or two collectors. Freescoo doesn’t need any water tank to store solar heat, since the system has an internal latent storage which guarantee the operation also after the sunset.
Furthermore:

  • The freescoo concept is modular and scalable.
  • Adsorption (ADS) and evaporative (EVA) modules can be applied separately respectively for dehumidification and cooling purposes to make Freescoo adaptable to different configurations.
  • Freescoo in new (or major renovation) buildings: Freescoo is an essential HVAC device for any high-performance building, and indispensable for the European nZEB parameters and Passivhaus Standard.
  • Freescoo in retrofit: substitution of existing low efficiency fan coils, AC splits in public/private/commercial buildings where minimum parameters of ventilation to guarantee comfort conditions are not satisfied (especially in crowded indoor areas).
