NOTE
• Based on 7.5 m piping length condition, According to piping length evaporating/condensing
temperature will be increasing/decreasing.
• ODU Capacity ratios mentioned in the table above are not exact.
• 'Evaporative temperature / Condenser temperature' may vary depending on system operating
frequency, pressure option setting and piping installation conditions.
• Single Split ODU is only supporting <1 system> table.
CAUTION
!
The actual temperature at the evaporator may vary by pressure drop. Please contact a local
sale person to design an AHU heat exchanger.
