I've a question here in which I am a little puzzled by..I have this data Quantity Units Set1 Set2 Set3 Set4
Refrigerant flow rate g/s 7.5 6.5 5.4 4.5
Condenser pressure kN/m^2 1125 1100 950 850
Evaporator pressure kN/m^2 290 225 185 145
Compressor inlet temp C 23.7 10 8.1 3.7
Compressor outlet temp C 67.3 65.7 63.6 61.7
Compressor input voltage V 225 225 225 225
Compressor input current A 4.5 4 3.8 3.8
Condenser outlet temp C 26.4 26.5 24.2 22.9
Evaporator inlet temp C 7.9 4.9 0.9 -3.8
Condenser water in temp C 15.5 15.7 15.7 15.7
Condenser water out temp C 34.2 32.4 30.4 28.2
Cooling water flow rate g/s 2.1 2.2 2.15 2.1
Compressor speed R.P.M 457 460 462 464
Evaporator input voltage V 220 200 185 170
Evaporator input current A 6.1 5.4 5.1 4.5
Brake force N 14.5 13 12.2 11.95

The questions I have is "using 134A property tables find the compressor, condenser and evaporator loads"..."compare these to the corresponding loads on the water and electrical inputs and explain any observed differences"
Now this is all good and well but I haven't the slightest idea what they want done and how to approach it..this coupled with plotting a R134a ph diagram. All other work is fine except this section of refrigeration. I would be eternally grateful for your collective and innate wisdom.
