Energy recovery units SupraBox COMFORT-2

Heat Recovery Efficiency of the Heat Recovery The SupraBox-Units are equipped with high efficiency cross counter flow plate heat exchangers made from corrosionresistant aluminum. The actual efficiency ratings that can be attained depend primarily on the operating conditions. Outdoor Air Temperature and Return Air Humidity During most times of the year the humidity of the return air is irreverent. If supply air and return air flow volumes are identical then the SupraBox attains efficiency ratings over 80%. With falling outdoor temperatures the surface temperature of the plate heat exchanger also...

Energy recovery units SupraBox COMFORT-3

Heat Recovery Level of Return Air Volume in relation to Supply Air Volume 200% Ventilation heat loss The level of the return air volume in correlation to the supply air also has a strong influence on the efficiency of the heat recovery. If the return air volume is reduced compared to the supply air volume, then the efficiency rating of the heat recovery with regards to the supply air is also decreased. By looking at the resulting ventilation heat loss, an assessment is made possible of the higher return air in regards to the supply air. Since the entire air volume in the room to be ventilated...
