Hello All,

*From the user's guide, the fan power should be removed from the
standard EER*rating of packaged cooling systems.

A 15-ton packaged rooftop single-zone system having an EER of 8.6 (COP of
2.5) is

specified for a building. The following table gives the design
specifications. How should

this be modeled?

Equipment parameter Value

Net Cooling Capacity (Btu/h) 174,000

Total Packaged Unit Input Power (W) 20,128

EER 8.64

Gross Cooling Cap (ARI conditions) 182,000

The supply fan power is the difference between the gross and the net cooling
capacity.

*So my Query is that Gross Cooling capacity ( ARI Condition ) is same
for all Packaged system of any tonnage ??? Is it standard one or what
???? ........Like i have 1.5 *

*ton of PTAC system, so for 1.5 ton of PTAC system also its gross
cooling capacity is same 182,000????*
