What Eurovent Certification Is Eurovent certification is an independent, third-party verification that a manufacturer’s published energy-recovery performance matches tested results. Certified products appear in a public directory with their verified ratings. Why It Reduces Risk Recovery effectiveness is easy to overstate in a brochure. Certification against a method such as EN 308 gives buyers a […]
Dew-Point Effectiveness vs Temperature Effectiveness: Two Numbers for ERV
Temperature effectiveness (sensible) Temperature effectiveness compares supply temperature change to the maximum possible: epsilon_T = (T_supply_out - T_supply_in) / (T_exhaust_in - T_supply_in) This is the number a sensible plate reports, and it is what most generic "efficiency" labels mean. Dew-point effectiveness (total / enthalpy) For an enthalpy wheel or membrane, moisture matters, so effectiveness is […]
