For SI: 1 British thermal unit per hour = 0.2931 W, °C = [(°F) - 32]/1.8.
 
 
"Cap" = The rated cooling capacity of the product in Btu/h. If the unit's capacity is less than 7,000 Btu/h, use 7,000 Btu/h in the calculation. If the unit's capacity is greater than 15,000 Btu/h, use 15,000 Btu/h in the calculations.
 
a
Chapter 6 contains a complete specification of the referenced standards, which include test procedures, including the referenced year version of the test procedure.
 
b
Nonstandard size units must be factory labeled as follows: "MANUFACTURED FOR NONSTANDARD SIZE APPLICATIONS ONLY: NOT TO BE INSTALLED IN NEW STANDARD PROJECTS." Nonstandard size efficiencies apply only to units being installed in existing sleeves having an external wall opening of less than 16 inches (406 mm) high or less than 42 inches (1067 mm) wide and having a cross-sectional area less than 670 square inches (0.43 m2).
 
c
The cooling-mode wet bulb temperature requirement only applies for units that reject condensate to the condenser coil.
 
d
"Cap" in EER and COPH equations for PTACs and PTHPs means cooling capacity in Btu/h at 95°F outdoor dry-bulb temperature.
