WebOur Products Speak For Themselves. Reach out today to see what they can do for you. Contact Us 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. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting wor… WebThe Danfoss #TrainCO2 mobile made it to the next stop on its North American tour in Irwindale, California at North American Sustainable Refrigeration Council (NASRC) #NatRefTraining Summit ... tint mart strathpine
