+//INPUT DATA
+TL=268;//Low temperature in K
+TH=293;//High temperature in K
+t=24;//time in hrs
+C=2100;//Capacity of refrigerator in kJ/s
+Tw=10;//Water temperature in oC
+L=335;//Latent heat of ice in kJ/kg
+
+//CALCULATIONS
+COP=TL/(TH-TL);//Co-efficient of performance
+Pmin=C/COP;//Minimum power required in kW
+Qr=(4.187*(Tw-0))+L;//Heat removed from water in kJ/kg
+m=C/Qr;//mass of ice formed in kg/s
+W=(m*t*3600)/1000;//Weight of ice formed in tons
