Cooling MBH based on 8
0
°F entering air temperature, 50% RH, and rated air flow.
KW includes compressor, outdoor fan and indoor blower motor watts. Add-on coils include 365 watts/1000 CFM for blower motor.
EER (Energy Efficiency Ratio) is the total cooling output in BTU’s at a 95°F outdoor ambient divided by the total electric power in watt-hours at
those conditions.
SEER (Seasonal Energy Efficiency Ratio) is the total cooling output in BTU’s during a normal annual usage period for cooling divided by the
total electric power
input in watt-hours during the same period.
