For other airflow conditions, see heating capacity correction factor (Table PD-19).
Net Heating Capacity and Power Input include indoor fan heat at nominal cfm and .40 inch ESP. To obtain net heating at other
conditions, subtract fan heat at this condition and add fan heat at new condition.
Heating capacities and powers are integrated to include the effects of defrost in the frost region.
All heating capacities and power (kW) are at 70% OD relative humidity.
