Active Recovery

Active recovery is a system of extraction air heat recovery used to comply with the requirements of the energy efficiency regulations for buildings and thermal facilities, incorporating an additional cooling circuit in the equipment. 

This system enables an increase of the equipment’s nominal power, which increases its compactness.

In addition, given that this additional system exchanges heat between the new air and the extraction air, in favourable temperature and humidity conditions, a high cooling performance is obtained.

This increases the nominal performance of the equipment and the seasonal performance subject to partial loads.

 

Dynamic Recovery

It is an extraction air energy recovery system that uses an additional exchange coil (subcooler) placed in series with the equipment’s air condensing unit, resulting in significant improvement to equipment efficiency regarding the reduction of compressor electrical consumption.

In addition, this system is advantageous compared to static recovery systems, as it prevents higher consumption from the induction and return fans, due to high load losses from these plate or rotary recuperators.

This system enables its installation on a rooftop with a return fan or extraction fan, which converts it into a very practical energy recovery system for both commercial and industrial applications.

 

Rotary Recovery

Rotary recovery involves a system of extraction air energy recovery that uses a rotary wheel, which enables the exchange of energy and mass between the extraction air and the new air, with a large exchange surface. 

Its high efficiency and the possibility to exchange heat and humidity enables an increase in the equipment’s nominal power.
