Coefficient of performance refrigeration h
WebCOP = Coefficient of Performance. NRE = Net Refrigeration Effect (Btu/lb) h = heat of compression (Btu/lb) Net Refrigeration Effect . Net refrigeration effect can be … 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.
