EER SEER2 COP HSPF2 kW/Ton Converter
This EER SEER2 COP HSPF2 kw/Ton Converter Calculator allows you to convert between SEER, HSPF, the DOE's new SEER2 and HSPF2 ratings, COP, and kW/Ton.
Visit SEER2's website to learn the Department of Energy's January 1, 2023, DOE's SEER2/SEER & HSPF2/HSPF requirements based on geographic location.
Instructions:
All inputs are required for full results
-
Review the methodology to make sure it aligns with your project's requirements.
-
Select the Efficiency Type that you want to convert from in the dropdown menu. Options Include:
COP, EER, SEER, SEER2, HSPF, HSPF2, kW/Ton, -
Enter the Efficiency Value. For example, for 15 SEER equipment, enter "15".
-
Enter the Equipment Type. This is required when converting to and from the DOE's Jan 1, 2023, HSPF2 and SEER2 energy ratings.
-
Click the Calculate buttons. The results will appear in the table.
Methodology and Equations:
The following conversion equations are used in the calculator:
EER = 0.875 x SEER
EER = 12 / kW/Ton
COP = 3.516/ kW/Ton
COP = EER / 3.413
COP = 0.293 x HSPF
Conversions between SEER2 and HSPF2 use RESNET's conversion factors which were created based on empirical data. The conversions are as follows:
SEER2 HSPF2
Single Package SEER x 0.96 HSPF x 0.84
Single Split SEER x 0.95 HSPF x 0.85
Small Duct High Velocity SEER x 1.00 HSPF x 0.85
Space Constrained SEER x 0.99 HSPF x 0.85
