AHE-35W/D AHE-50W/D AHE-60W/D AHE-80W/D AHE-100W/D AHE-100WB1/D AHE-120WB1/D
During summer operation, the fresh air obtains cold energy from the exhaust air of the air conditioner to lower the temperature, and at the same time, the water vapor in the fresh air penetrates into the exhaust air under the action of partial pressure; during winter operation, the fresh air obtains heat energy from the exhaust air of the air conditioner to increase the temperature , the water vapor in the exhaust air has just penetrated into the fresh air.
Why do energy recovery ventilator require high static pressure?
Energy recovery ventilators (ERVs) require high static pressure for several reasons:
Airflow Resistance: ERVs typically have air filters and heat exchange cores that introduce resistance to the airflow. To overcome this resistance and maintain the desired airflow rate, the ERV needs to operate at a higher static pressure.
Ductwork: ERVs are connected to the building's ventilation system through ductwork. The ductwork itself introduces resistance to airflow due to its length, size, and the presence of fittings like bends and dampers. The ERV needs to generate enough static pressure to overcome this resistance and ensure proper distribution of fresh air throughout the building.
Heat Exchanger Efficiency: ERVs use heat exchangers to transfer heat and moisture between the incoming and outgoing air streams. These heat exchangers are designed to maximize heat transfer efficiency. To achieve efficient heat exchange, the airflow across the heat exchanger needs to be balanced. High static pressure helps ensure that the airflow is evenly distributed across the heat exchanger, optimizing the heat recovery process.
Air Leakage: High static pressure helps minimize air leakage in the ERV system. By maintaining a higher pressure inside the ERV, the likelihood of air leakage through gaps, joints, or seals is reduced, improving the overall performance and efficiency of the system.
It's important to note that the specific static pressure requirements can vary depending on the design and specifications of the ERV unit.
