CONVERTING KW/TON TO COP or EER


(ex: If a chiller's efficiency is rated at 1 KW/ton,
the COP=3.5 and the EER=12)
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



ELECTRIC UTILIZATION INDEX (EUI)

Calculate EUI by dividing annual KWh consumption by the facility's square footage. Use this table for general comparison purposes only ...
