In a test of a simple vapor compression refrigeration cycle operating at a steady state condition, the chilled water, at a rate of 800 liter/min entered at 11 C and left at 6 C, while the cooling water temperature difference was 7 "C at a rate of 1000 liter/min cooling water. Sketch the simple refrigeration cycle and its ideal P-h chart, and then calculate: a- the cooling capacity (in kW). b- the compressor power (in kW). c- the cycle COP. (Make a comment on the value of the COP)
