Unit: THA2AC. Air Conditioning Unit (two condensers.
(water and air) and one evaporator (air))

1.-Determination of the inlet power, heat produced and performance coefficient. Air as heat source.

2.- Preparation of performances curves of the unit whit different inlet and outlet temperatures. Air as a heat source.

3.- Lay out of the steam compression cycle in a diagram P-H and comparison with the ideal cycle. Air as heat source.

4.- Preparation of the performance curves of the unit based on the properties of the refrigerant and at different condensation and evaporation temperatures. Air as heat source.

5.- Energy balances.

Other possible practices:

6.- Temperature sensors calibration.

7.- Flow sensors calibration.

8.- Pressure sensors calibration.

9-27.- Practices with PLC.
