SEPR - STULZ answers

The Seasonal Energy Performance Ratio (SEPR) is an adapted ESEER measurement. SEPR takes more account of all possible temperature influences based on the number of hours per year.  This ratio is obtained from the respective capacity figures of the chillers at four different ambient temperatures and various load levels (100, 93, 87 and 80 percent).  The higher the SEPR value, the more energy-efficient the cooling system.

SEPR=Qcoolingcapacity* / Pelectric
