Note :
1. ODU Capacity ratios mentioned in the table above are not exact.
2. Evaporative temperature / Condenser temperature may vary depending on system operating frequency,
pressure option setting and piping installationconditions.
3. The evaporator temperature is based on target low pressure of compressor. The actual temperature at
the evaporator may vary by pressure drop. Please contact your LG representative to design an AHU
heat exchanger.
