   The SEER (Seasonal Energy Efficiency Ratio) rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. smoke damper A damper or adjustable louver designed to augment the ventilation of a space during ...

6. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   Less work is required to move heat than for conversion into heat, and because of this, heat pumps, air conditioners and refrigeration systems can have a coefficient of performance greater than one. The COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often ...
