Answer all parts please

(a) Draw a schematic showing the layout of a lithium bromide based absorption refrigeration system? (b) Describe the operation of the system drawn in part (a) and identify typical key operating parameters. (c) List five desirable properties for a refrigerant (d) A simple cycle refrigerator using R134a has compressor inlet and outlet pressures of 2.5bar and 11bar respectively. The liquid leaving the condenser is sub cooled by 10C and that leaving the evaporator is superheated by 5C. The mass flow rate of refrigerant in the cycle is 30g/s. The compressor has an isentropic efficiency of 70%. Assuming that there are no pressure drops in the condenser or evaporator: i. Plot the cycle on the P-h chart. ii. Calculate the evaporator load. [4.6kW] iii. Calculate the COP for the unit. [3.35]
