Notes:
1. Dry coil condition. Total gross capacity (MBh) shown to the left is not applicable. In this case the Sensible Heat Capacity (SHC) is the total capacity.
2. All temperatures are in °F.
3. All capacities shown are gross and have not considered indoor fan heat.
4. To obtain net cooling capacities, subtract indoor fan heat.
5. MBH = Total Gross Cooling Capacity
6. SHC = Sensible Heat Capacity
