The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity. The EER is related to the coefficient of performance (COP) commonly used in thermodynamics, …
WebThe Energy Efficiency Rating (EER): is the amount of heat removed from the cooled space in BTU’s for 1 Wh (watt‐hour) EER = 3.412 COPR Most air conditioners have an EER between 8 to 12 (COP of 2.3 to 3.5). The Second Law … WebEnergy Efficiency Ratio (EER) is a rating system used to measure the efficiency of an air conditioner. A higher EER is better. Ingrams Water and Air Equipment. Search: Search. …
