American Journal of Physics
written by Harvey Leff and William Teeters
The relation between the energy efficiency ratio (EER) of an air conditioner and the coefficient of performance (COP) of its refrigeration cycle is discussed. Two other efficiency parameters, the total COP and total EER, measured relative to the energy extracted by a primary energy source (e.g., a fossil fuel), are defined. A comparison of the actual total COP (or total EER) relative to its maximum allowed value, consistent with the second law of thermodynamics, leads to an estimate for air conditioners of the second law efficiency.
