How can the cop be maximised for a heat pump
WebYes, air source heat pumps work below 20 degrees Fahrenheit —in fact, they can perform well below -10! If you’re worried—or if you live in Antarctica—you can get a cold-climate heat pump with a supplemental heating system in case of emergencies (the vast majority of people never need it). WebCalculation of COP (coefficient of performance) COP is generally used for evaluation of various heat pump systems. Using the method discussed above, COPs of AHP and RHP are caluculated. Fig. 8 shows the feature of RHP. In this case temperature amplifier or resorption heat transformer (RHT) is considered. RHT has two solution circuits.
