The performance of vapor compression refrigeration cycles is restricted by thermodynamics.[50] These air conditioning and heat pump devices move warmth rather than convert it from 1 type to another, so thermal efficiencies don't properly describe the overall performance of these equipment. The Coefficient of general performance (COP) steps functionality, but this dimensionless measure hasn't been adopted. In its place, the Electrical power Effectiveness Ratio (EER) has typically been used to characterize the overall performance of numerous HVAC programs. EER would be the Power Performance Ratio based upon a 35 °C (95 °File) outside temperature. To much more properly describe the overall performance of air con products more than a typical cooling year a modified version of your EER, the Seasonal Electrical power Effectiveness Ratio (SEER), or in Europe the ESEER, is used.
