C symbol thermodynamics
WebCoefficient of performance. 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. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. WebCh 4, Lesson B, Page 13 - Heat: Symbols and Sign Convention. The top table summarizes the symbols related to heat transfer and the appropriate units for each. The second table restates the sign convention for heat that we will use in Thermo-CD. Remember that heat is energy transferred across a system boundary because of a …
