what is a typical eer value
Definition 1: EER, energy efficiency ratio: Is the measure of air conditioner efficiency at maximum air conditioning load. It is measured by ratio of Btu/hour of cooling or heating load, to watts of electrical power input. The unit is in Btu hr-1 W-1. Definition 2: SEER, seasonal energy efficiency ratio: The measurement units of SEER is exactly the same as EER, but the difference lies in the data used for the measurement. Values for SEER, is determined through averaging readings of different air conditions, to represent air conditioner efficiency throughout the season.
