hello .this is  A CONCLUSIONS of simple air conditioning experiment 

can you correct the mistakes for me?

In the first experiment we have the air and refrigerant as a flow throw the device so we will get Moisture Addition and Pre-Heating from section A to B and Cooling and Condensation from section B to C .the properties of the air we find them from psychometric chart and the properties of the refrigerant from P-h chart. The refrigerant cycle will give us the compressor work, heat rate to evaporator and heat rate from condenser so from these value we can find the coefficient of performance for cooling and heating, after we get the formula for COP we know how to increase it by increasing the heat rate required and decreasing the input work. We have sub cooling at the expansion valve and saturated liquid inter to expansion valve. At the inlet of compressor we have saturated vapor and super-heated happen in compressor. The heat rate of condenser out and evaporator in. the second and third experiment we have only the air so we will just get Moisture Addition and Pre-heating because we have evaporator that will increase the temperature. At pre-heating the energy input have the same or close to energy air transfer. We have some errors in this experiments due to the losses and precision of measurement.
