To calculate the Carnot coefficient of performance: Determine the temperature of the hot reservoir (Th) in K or °R. Determine the temperature of the cold reservoir (Tc) in K or °R. Use the coefficient of performance formula: For a reversible refrigerator: COPr = 1/(Th/Tc - 1). For...
thatremoves the greatest amount of heatfrom the inside of the refrigerator (cold reservoir) for the least expenditure of mechanical work or electric energy. The relevant ratio is, therefore, the larger this ratio, the better the refrigerator. ...
