The amount of cooling provided by a central air conditioner per unit of electricity purchased; SEER is tested over the entire cooling season, taking cycling into account. The higher the SEER number, the more efficient the air conditioner. SEER, in contrast to EER and COP, takes into account the efficiency losses resulting from system cycling.
A calculated air-conditioning performance rating defined by the U.S.D.O.E. Air-conditioning Test Procedure and describing the seasonal performance of an air conditioner for a typical residential load. SEER is equal to the total annual cooling output in Btu divided by total electrical energy input in watt-hours.
An equipment efficiency rating that takes into account the startup and shutdown for each cycle.
The total cooling output of an air conditioner during its normal annual usage period for cooling, in Btu/h (W), divided by the total electric energy input during the same period, in watt-hours, as determined by DOE 10 CFR Part 430, Subpart B, Test Procedures. New equipment ranges from about 10 to 16 SEER. Higher SEER ratings indicate more efficient equipment.
(SEER) - The total cooling output of a central air conditioner in British thermal units during its normal usage period for cooling divided by the total electrical energy input in watt-hours during the same period. The test procedure is determined by the Air-Conditioning and Refrigeration Institute.
The average cooling efficiency over an entire cooling season.
SEER): The total cooling output of a central air conditioning unit in British thermal units during its normal usage period for cooling divided by the total electrical energy input in watthours during the same period, as determined using specified federal test procedures.
A measure of seasonal or annual efficiency of a central air conditioner or air conditioning heat pump. The higher the SEER, the more efficient the unit. A rating of 14.5 or higher for a new unit is recommended. The formula for the rating takes the average number of Btu of cooling divided by the watt-hours of electricity used by the unit for a hypothetical "average" U.S. climate.
A measure of seasonal or annual efficiency of a central air conditioner or air conditioning heat pump. It takes into account the variations in temperature that can occur within a season and is the average number of Btu of cooling delivered for every watt-hour of electricity used by the heat pump over a cooling season.
The efficiency of air conditioners are often, but not always, rated by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner.
