Weba Annual Fuel Utilization Efficiency (AFUE) is the ratio of annual output energy to annual input energy, which includes any non-heating season pilot input loss and, for gas or oil-fired furnaces or boilers, does not include electric energy. Residential Boilers are covered by ENERGY STAR and use AFUE as the efficiency metric. Web9 Example of a set of efficiency coefficients and how to calculate useful energy 9 Recommendations, and topics for discussion in the group 2. What is a thermal efficiency coefficient? In thermodynamics, the thermal efficiency E th is a performance measure of a thermal device such as an internal combustion engine, a boiler, or a furnace. The input Q
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP … See more According to the first law of thermodynamics, after a full cycle of the process $${\displaystyle Q_{\rm {H}}+Q_{\rm {C}}+W=\Delta _{\rm {cycle}}U=0}$$ and thus See more A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of … See more 1. ^ "Archived copy" (PDF).
