Compression cooling formula
WebCompression Horsepower Calculator (method 1) Compression Work (W): Btu/min. Calculate. Compression Horsepower (P): hp. The second formula for compression horsepower is: P = c 42.4 ⋅ COP P = c 42.4 ⋅ C O P. Where P is the compression power in horsepower (hp), c is the capacity in Btu/min, and COP is the coefficient of performance.

WebJul 22, 2024 · Heating BTUs = CFM x ∆t x 1.08. • CFM = the fan CFM plotted on the fan tables, or measured at several points in the system. • ∆t = the dry bulb temperature change through the system. • 1.08 = the heating BTU multiplier at sea level, or .075-lbs. of air per CFM x .24 (the specific heat of air) x 60 (minutes in an hour.) WebIt implies the ratio of cooling output at the evaporator to the work input for the air conditioner or refrigerator. It also implies the ratio of heat extract value at the condenser to the work input for the heat pump. If COP is more, power consumption is more, and operating costs will be more. Coefficient of Performance or COP Formula
