DESIGN AND PROJECT WARRANTY
Accuair heat recovery system already meets without difficulty ECO Design Directive 1253 of 2018. The Directive provides that the high values of efficiency by heat recovery go to offset the power consumption of the fans. In this way, with an efficiency of 90%, producers can build much more compact AHU. Slightly higher pressure drop values, due to the filters, are compensated by the high efficiency.
MAXIMUM EFFICIENCY
MOISTURE RECOVERY
Thanks to its specific enthalpy storage structure the heat recovery ventilation system is able to recover the moisture contained in the exhaust air in the winter months. The value of the recovery of moisture exceeds 70%, avoiding in this way in the winter months a too dry climate in the room.
ANTIFREEZE
The heat recovery system is frost resistant up to a temperature of -25°С. Therefore, it did not need expensive bypass systems or preheating. ERI Corporation guarantees a high degree of efficiency for the whole year. The high performance heat accumulator represents today the most efficient system for heat recovery for air treatment systems, existing on the market. It improves comfort without the addition of further humidification systems.

OPERATION
Our heat recovery ventilation system consists of two static accumulation masses that alternately are heated by the exhausted warm air. The damper system serves to direct the flow of air in and out in the relevant areas of accumulation. The sector loaded with warm exhaust air is used in the next cycle for the incoming air. This is heated almost to the temperature of the indoor environment and is introduced into the building through the air entrance. At the same time after that the sector with the air inlet has been discharged, it is automatically converted on the flow of exhausted air, in this way the sector is again heated in the next cycle.
POWER CONTROL
The adjustment of the performance occurs through the variation on the time interval of the frequency deviation of the dampers, which can be adjusted from 100% to 0%. With 0% value, the dampers are no longer changed and it enable a free cooling of the building through the air entrance. The gradual adjustment of the system is regulated through a 0-10 V external signal.
SELECTION SOFTWARE
The selection software calculates the necessary technical operating data of the AHU and is also available as stand alone Black Box or as dll for ready integration into your running calculation system.
