The Coefficient of effectiveness (COP) measures general performance, but this dimensionless measure has not been adopted. In its place, the Vitality Performance Ratio (EER) has usually been accustomed to characterize the effectiveness of numerous HVAC programs. EER will be the Energy Efficiency Ratio dependant on a 35 °C (ninety five °F) outdoor temperature.
