Definitions for "Coefficient of Performance"
Measurement of the steady-state performance of electrically operated systems, including ground-source heat pumps. It is the ratio of useful-energy output to purchased-energy input. Can also refer to gas-fired systems.
A ratio of the work or useful energy output of a system versus the amount of work or energy inputted into the system as determined by using the same energy equivalents for energy in and out. Is used as a measure of the steady state performance or energy efficiency of heating, cooling, and refrigeration appliances. The COP is equal to the Energy Efficiency Ratio (EER) divided by 3.41(2) The higher the COP, the more efficient the device.
The ratio of total useful work output by a machine to the net energy input. Units must be consistent.
