Coefficient of Performance Formula - GeeksforGeeks

WebThe efficiency of a perfect, or Carnot, engine is Ef f C =1−(T c T h) E f C = 1 − ( T c T h); thus, the smaller the temperature difference, the smaller the efficiency and the greater the COPhp (because COP hp = 1 Eff C O P hp = 1 E f ). In other words, heat pumps do not work as well in very cold climates as they do in more moderate climates. WebThe Coefficient of Performance (COP) is a measure of the efficiency of a refrigeration or air conditioning system. It is defined as the ratio of the amount of cooling provided by the system to the amount of energy required to operate the system. The formula for COP is: ` COP = NRE / h ` ds2 two handing
