Show simple vapour compression Refrigeration cycle with showing all the devices and also draw T-sand P-R diagram and illustrate it also.
A Bell-Coleman cycle works between 1 bar and 6 bar. Compression and expansion follows PV1.25 = C. Determine COP and capacity of unit in tons of Refrigeration if the air flow is 0.5 Kg/Sec. Consider expansion and compression starts at 7OC and 37OC respectively. Neglect clearance.
