Coefficient of performance
The coefficient of performance or COP of a heating or cooling of a system is a ratio of useful heating or cooling provided to work required.
Formula used :
\[COP_{heating}=\frac{T_{heat}}{T_{heat}-T_{cold}} \]
\[COP_{cooling}=\frac{T_{cold}}{T_{heat}-T_{cold}} \]
let x be the value of Theat and y be the value of Tcold
