WebCOP = Coefficient of performance, kW/kW Cooling Capacity = Cooling Output, kW Power Consumption = Power Input, kW Since the cooling capacity of air conditioners is often rated in BTU (British Thermal Unit), … WebJan 1, 2012 · Models must meet or exceed the energy efficiency ratio (EER) and coefficient of performance (COP) values in the tables above. The specifications in the charts above apply to single stage models. Multi-stage models may be qualified based on: EER = (highest rated capacity EER + lowest rated capacity EER) / 2
WebThe EER can be calculated as EER = (10000 Btu/h) / (1000 W) = 10 HSPF - Heating Season Performance Factor The Heating Season Performance Factor - HSPF - is a measure of the overall heating efficiency of a heat … WebBtu/hr). An EER of 10 yields a COP of 2.9. Refrigeration systems are also rated in terms of tons of refrigeration. One ton of refrigeration is equivalent to 12,000 Btu/hr or 211 kJ/min. How did the term “ton of cooling” originate? Reversed Carnot Refrigerator and Heat Pump Shown below are the cyclic refrigeration device operating between two
