Start With the Test Standard<\/h2>\n

First confirm which<\/em> standard the report uses \u2014 AHRI 1060<\/a> oder EN 308<\/a>. The method defines the conditions, so a number from one standard is not directly comparable to a number from another.<\/p>\n

Sensible vs Total Effectiveness<\/h2>\n

Read both sensible<\/strong> (temperature) and total<\/strong> (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.<\/p>\n

Airflow Balance and Pressure Drop<\/h2>\n

Check the effectiveness at your actual airflow split<\/strong>, not just balanced flow. Then read the pressure drop on both sides<\/strong> \u2014 fan energy depends on total external static pressure, and a high or unbalanced drop can erase the savings recovery provides.<\/p>\n

Leakage and Carryover<\/h2>\n

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<\/a>.<\/p>\n

Frequently Asked Questions<\/strong><\/p>\n

\n

Which effectiveness number should I trust?<\/h3>\n

Trust the one measured at your operating conditions and airflow balance; nameplate effectiveness at balanced flow often overstates real unbalanced performance.<\/p>\n<\/div>\n

\n

Why check pressure drop on both sides?<\/h3>\n

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.<\/p>\n<\/div>\n

One-page checklist<\/strong>
Before you accept a recovery unit, tick these off from the test report: (1) same standard as your spec AHRI 1060 or EN 308; (2) both sensible and total effectiveness where moisture matters; (3) effectiveness at your real airflow split, not balanced flow; (4) pressure drop on both sides within your fan budget; (5) leakage or carryover figures for the core type. If any line is missing, ask for the full sheet a headline number with no conditions is not comparable across suppliers.<\/p>\n
