Question

During an experiment to simple vapour compresion cycles in the HVAC lab at Faculty of Engineering, Rabigh , the following data are obtained:-

• The temperature enter to the compressor is "saturated vapor condition".

• The temperature exit the compressor is 55 0C.

• The temperature enter to the expansion device is 18.5 0C.

• The evaporator gauge pressure is 3.05 bar.

• The condenser gauge pressure is 10.7 bar.

• The volume flow rate at the evaporator entrance is 1.5 lit,/min
