Thermal efficiency - Wikipedia
In thermodynamics, the thermal efficiency ($${\displaystyle \eta _{\rm {th}}}$$) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, … See more
In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, $${\displaystyle Q_{\rm {in}}}$$, to the device is See more
For a device that converts energy from another form into thermal energy (such as an electric heater, boiler, or furnace), the thermal efficiency is
$${\displaystyle \eta _{\rm {th}}\equiv {\frac {|Q_{\rm {out}}|}{Q_{\rm {in}}}}}$$
where the See more
