+
+//INPUT DATA
+T2=40;//Temperature at point 2 in oC
+T1=-10;//Temperature at point 1 in oC
+h2=367.155;//Enthalpy at point 2 from refrigerant-12 tables in kJ/kg
+s2=1.54057;//Entropy at point 2 from refrigerant-12 tables in kJ/kg-K
+s1=1.54057;//Entropy at point 1 from refrigerant-12 tables in kJ/kg-K
+sg=1.56004;//Entropy from refrigerant-12 tables in kJ/kg-K
+sf=0.96601;//Entropy from refrigerant-12 tables in kJ/kg-K
+hf=190.822;//Enthalpy from refrigerant-12 tables in kJ/kg-K
+hfg=156.319;//Enthalpy from refrigerant-12 tables in kJ/kg-K
+h3=238.533;//Enthalpy at point 3 from refrigerant-12 tables in kJ/kg-K
+h4=h3;//Enthalpy at point 4 from refrigerant-12 tables in kJ/kg-K
+
+//CALCULATIONS
+x1=(s1-sf)/(sg-sf);//Quality factor
+h1=hf+(x1*hfg);//Enthalpy at point 1 from refrigerant-12 tables in kJ/kg
+COP=(h1-h4)/(h2-h1);//Co-efficient of performance
+
+//OUTPUT
+mprintf('COP of the system is %3.2f',COP)
