condenser Problem: An ammonia refrigerating system shown in the figures composed of three evaporators and arranged with multiple expansion valves and Intercoolers. The food and operating temperature of each evaporator are shown in the table below: perfor Compresor Intercooler 2 evaporator 2 compresor Intercooler quid evaporatori compressor Evaporator Load, tons 1 2 3 30 20 15 Evaporator Temperature, "C - 20 - 15 - 10 Condensing pressure is 1200 kPa. Saturated conditions exist of the exits of the evaporators and the condenser Liquid refrigerant leaves the condenser at 28°C. Determine a the mass flow rate in evaporator 1 kg/ b. the moss low rate in evaporator 2 kg/ c. the mass flow rate in evaporator 3. kg/s kg/ kg/ d. the mass flow rate in intercooler e. the mass flow rate in intercooler 2 the work of compressor 9. the work of compressor 2 kW kW n. the work of compressor 3 KW
