- First confirm which standard the report uses — AHRI 1060 or EN 308. The method defines the conditions, so a number from one standard is not directly comparable to a number from another.
- Read both sensible (temperature) and total (enthalpy) effectiveness. A plate exchanger only reports sensible; an enthalpy wheel reports both, and the gap between them tells you how much moisture it moves.
- Check the effectiveness at your actual airflow split, not just balanced flow. Then read the pressure drop on both sides — fan energy depends on total external static pressure, and a high or unbalanced drop can erase the savings recovery provides.
- For wheels, check carryover (supply-to-exhaust) and purge-sector performance; for plates, check leakage. Contaminated streams need separated cores. See the effectiveness and standards overview.
- Send us the report and we will benchmark it against your duty. Contact our engineers or email kuns913@gmail.com / WhatsApp +86 15753355505. Frequently Asked Questions Which effectiveness number should I trust? Trust the one measured at your operating conditions and airflow balance; nameplate effectiveness at balanced flow often overstates real unbalanced performance. Why check pressure drop on both sides? Fan energy depends on total external static pressure; an unbalanced or high pressure drop on one side can erase the energy savings the recovery provides.
