Definitions for "Seasonal Energy Efficiency Ratio"
Keywords:  seer, btu, watt, cooling, efficient
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.
