How to Calculate Minimum Work required when Cooling Ratio is fixed?
Minimum Work required when Cooling Ratio is fixed calculator uses Work Required = (Polytropic Index for Compression/(Polytropic Index for Compression-1))*Mass of refrigerant in kg per minute*[R]*((Suction temperature at Low pressure Compressor*(Discharge Pressure of High Pressure Compressor/Suction Pressure of Low Pressure Compressor)^((Polytropic Index for Compression-1)/(2*Polytropic Index for Compression))+Discharge Temperature of Refrigerant*(Discharge Pressure of High Pressure Compressor/Suction Pressure of Low Pressure Compressor)^((Polytropic Index for Compression-1)/(2*Polytropic Index for Compression))-Suction temperature at Low pressure Compressor-Discharge Temperature at high pressure compressor)) to calculate the Work Required, The Minimum Work required when Cooling Ratio is fixed formula is defined as the minimum amount of work required to run the multi-stage compressor when the cooling ratio is fixed. Work Required is denoted by W symbol.
How to calculate Minimum Work required when Cooling Ratio is fixed using this online calculator? To use this online calculator for Minimum Work required when Cooling Ratio is fixed, enter Polytropic Index for Compression (nc), Mass of refrigerant in kg per minute (m), Suction temperature at Low pressure Compressor (T1), Discharge Pressure of High Pressure Compressor (P3), Suction Pressure of Low Pressure Compressor (P1), Discharge Temperature of Refrigerant (Tdischarge) & Discharge Temperature at high pressure compressor (T3) and hit the calculate button. Here is how the Minimum Work required when Cooling Ratio is fixed calculation can be explained with given input values -> 461.5352 = (1.2/(1.2-1))*0.0333333333333333*[R]*((300*(1500000/200)^((1.2-1)/(2*1.2))+450*(1500000/200)^((1.2-1)/(2*1.2))-300-1000)).
