Cop of refrigeration formula
WebSep 9, 2024 · The coefficient of performance of the fridge is the refrigerating effect per cycle, Q1, divided by the net work done on the fridge per cycle, and, for a Carnot cycle it can be calculated from T1 / ( T2 − T1 ). 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…

WebChiller Efficiency = Power Consumption (kW) ÷ Chiller Capacity (RT) Chiller Efficiency = 164.9 ÷ (890 x 3412 ÷ 12000) Chiller Efficiency = 0.65 kW/Ton. Using the same principle, … WebThe Coefficient of Performance (C.O.P) of a Simple Vapor Refrigeration Cycle is C.O.P. = (heat extracted or refrigerating effect) / Work done. C.O.P. = (h2-h4) / (h3-h2). The detailed explanation of Vapor Compression Refrigeration cycle is h ere Now let's see about Refrigerants and its classification. Refrigerants:
WebHow to calculate COP? In reference to the standard heat engine, Coefficient of Performance is given by K = Q c W i n Where, k = Coefficient of Performance Q c = Heat dispelled from the system W in = Work input to the system If no work was input to the system (W in = 0) the Coefficient of Performance would equal infinity. Hence, K < ∞ WebApr 11, 2024 · COP = 5.5. If you want to calculate in imperial units then follow this calculation; 1 Kw = 3412.142 Btu/h. So. 8,533,364 Btu/h ÷ 3412.142 = 2500 Kw. COP = 2500 Kw / 450 Kw. COP = 5.5. You'll see that these COP comes out of five point five that's very good that's really very good so what this means is that for every one kilowatt of …
WebJul 22, 2024 · Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. Q = (999.78kg/m3 x 0.0995m3/s) x 4.19kJ/kg/K x ( (12*c+273.15K) – (6*c+273.15K)) We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final … WebThe formula for COP is: ` COP = NRE / h ` Where COP is the coefficient of performance, NRE is the net refrigeration effect in Btu/lb, and h is the heat of compression in Btu/lb. …
WebIn a refrigeration cycle, the desired output is Q C, because the goal is to remove heat from the cold reservoir. The required input is the work input, W ref. So, COP R = Q C over W …
