EDMMT712101 The Correction Ratio of Exchange Efficiency
VAM-HVE/HVLT Series 97
8. The Correction Ratio of Exchange Efficiency
<Example of correction>
VAM500 (50 Hz): Airflow rate at high notch 500 m
3
/ H
(Cooling) Enthalpy exchanging efficiency
62.5%
Supply air and exhaust airflow rate for fresh-up mode:
Supply airflow rate / Exhaust airflow rate = 520 / 500 = 1.04
(Cooling) Enthalpy exchange efficiency from above Table
62.5 0.98 = 61.3%
