Cooling and Heating Ratings
Cooling Ratings
EER = Energy Efficiency Ratio at full load - the cooling capacity in Btu’s per hour (Btuh) divided by the power input in watts, expressed in Btuh per
watt (Btuh/watt).
EER; condensing unit only ratings based on 45º F SST and 95ºF entering outdoor air temperature.
IEER - A single number cooling part-load efficiency figure that is calculated based on equipment stages and EER at these capacity stages (ANSI/
ARI STD 340/360 - 2007)
LEGEND
EER = Energy Efficiency Ratio
SST = Saturated Suction Temperature
ARI = Air Conditioning and Refrigeration Institute
IEER = Integrated Energy Efficiency Ratio
