Converting KW / TON to COP or EER |
Example: if equipments efficiency is rated at 1 KW/ton, the COP=3.5 and the EER=12 |
Calculate Electric Utilization Index (EUI) by dividing annual KWh consumption by the facility's square footage. |
|
(ex: If a chiller's efficiency is rated at 1 KW/ton, |
|
KW/ton |
= |
(12)/EER |
KW/ton |
= |
(12)/(COP x 3.412) |
EER |
= |
(12)/KW/ton |
EER |
= |
COP x 3.412 |
COP |
= |
(EER)/3.412 |
COP |
= |
12/(KW/ton)/3.412 |
