For the purpose of acting as an air-cooled water chiller, an ammonia refrigerant vapor compression system is deployed. It is functioning with an evaporator temperature of 0 degrees Celsius and a condenser temperature of 40 degrees Celsius. The refrigeration produced by the system is equal to 15 tons. Find out: a. The temperature of the discharge and the mass flow rate of the refrigerant that is being circulated. b. The piston displacement that can be considered theoretical for the compressor. c. The work that can be done by the theoretical compressor. d. The heat that is not allowed to escape through the condenser. e. The Carnot coefficient of performance and the actual COP of the cycle. f. The volume of air that is supplied in the condenser if the air comes in at 30 degrees Celsius and exits at 34 degrees Celsius. g. The LMTD and AMTD of the condenser h. The water flow rate of the chiller assuming that the water enters the evaporator at 10 degrees Celsius and exits at 5 degrees Celsius i. The LMTD and AMTD measurements taken in the evaporator
