Design and application
- The aluminum rotor (nozzle), mounted on the shaft, is built into a steel frame structure.
- Rotor design - alternately laid flat and wave-shaped aluminum bands and forming channels for air passage.
- Variable speed electric drive to maintain maximum efficiency and control the degree of energy recovery.
- A cleaning airlock limits to a minimum the flow of "contaminated" exhaust air into the supply side of the unit.
- A seal placed around the rotor rim and on the airflow interface provides additional protection against overflows.
- Energy recovery is achieved by cooling the warm air stream (exhaust or outside air) and transferring the heat to the cooler air stream flowing in the opposite direction.
- Moisture recovery occurs when the surface temperature of the heat exchanger nozzle is below the dew point temperature or when a hygroscopic coating is present
Features
- Energy recovery efficiency reaches 86%, depending on airflow rates, mass flow rates, and relative humidity
