A client requested to build a freezer to store fish at -2C using a vapor absorption system. Based on the requirements, the generator, condenser, and absorber of the refrigeration system operating at temperatures of 110C, 40C, and 30C, respectively.

(i) What is the minimum pressure at the condenser?

(ii) What is the maximum pressure at the evaporator?

Calculate:

(iii) The refrigerant concentration at the generator and absorber,

(iv) The mass flow rate entering condenser and absorber, when the mass flow rate of the pump is 0.85 kg/s, and

(v) The coefficient of performance (COP) of the system.
