WebMar 1, 2024 · On the other hand, classifying heat pipes by their use and shape, there are many different types: a constant conductance heat pipe (CCHP), a loop heat pipe (LHP), an oscillating heat pipe (OHP), a variable conductance heat pipe (VCHP), a flexible heat pipe, and so on. 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.
