+//INPUT DATA
+T2=40;//Temperature at point 2 in oC
+T1=-5;//Temperature at point 1 in oC
+h2=367.155;//Enthalpy at point 2 from F-12 tables in kJ/kg
+sg=1.55717;//Entropy from F-12 tables in kJ/kg-K
+s1=1.54057;//Entropy at point 1 from F-12 tables in kJ/kg-K
+sf=0.98311;//Entropy from F-12 tables in kJ/kg-K
+hf=195.394;//Enthalpy from F-12 tables in kJ/kg
+hfg=153.934;//Enthalpy from F-12 tables in kJ/kg
+h4=238.533;//Enthalpy at point 4 from F-12 tables in kJ/kg
+h4s=218;//Enthalpy at point 4 with subcooling from F-12 tables in kJ/kg
+
+//CALCULATIONS
+x1=(s1-sf)/(sg-sf);//Quality factor
+h1=hf+(x1*hfg);//Enthalpy at point 1 from refrigerant-12 tables in kJ/kg
+COPns=(h1-h4)/(h2-h1);//Co-efficient of performance with no subcooling
+COPs=(h1-h4s)/(h2-h1);//Co-efficient of performance with subcooling
+
+//OUTPUT
