Start With the Test Standard 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. Sensible vs Total Effectiveness Read both sensible (temperature) and total (enthalpy) effectiveness. A plate exchanger only reports […]
EN 308: Test Procedures for Air-to-Air Heat Transfer in Recovery Equipment
Purpose of EN 308 EN 308 is the European standard that specifies test procedures for air-to-air heat transfer in heat recovery equipment. Rather than setting a pass/fail threshold, it defines how to measure temperature effectiveness and, for enthalpy devices, moisture effectiveness under controlled inlet conditions. What Gets Measured The test fixes inlet dry-bulb temperatures and, […]
