The overall performance of vapor compression refrigeration cycles is restricted by thermodynamics.[36] These air conditioning and heat pump equipment move warmth instead of convert it from just one sort to another, so thermal efficiencies never correctly describe the performance of those units. The Coefficient of general performance (COP) actions overall performance, but this dimensionless measure hasn't been adopted. Alternatively, the Energy Performance Ratio (EER) has typically been accustomed to characterize the general performance of numerous HVAC systems. EER could be the Energy Performance Ratio based on a 35 °C (95 °File) out of doors temperature. To a lot more accurately explain the general performance of air conditioning machines over a typical cooling season a modified Edition of your EER, the Seasonal Electricity Effectiveness Ratio (SEER), or in Europe the ESEER, is utilized.
