4. A supermarket refrigeration system uses Ammonia as the refrigerant. It has an evaporation temperature of 30°C. If it is an Ideal Refrigeration cycle with 2 kg/s of mass flow for the ammonia, and it provides 2215.3 kW of cooling, how much work must be added to the compressor? Answer: about 630 kW Hint: consider solving the cycle clockwise: i.e. going from point I to point 4, etc.. You'll need to do some interpolating at the ena

A freezer is designed, based on vapor-compression refrigeration cycle. The designed conditions are: R-134a as refrigerant, with a cooling capacity of 500 kW; compressor of 70% efficiency, with a superheat of 10°C before compressor inlet; operation temperature of -10°C inside the refrigerator, with the environment temperature of 25°C outside the refrigerator; Determine the pressure range of refrigeration cycle if a 10°C difference is required to ensure effective heat transfer of evaporator and condenser; Plot the refrigeration cycle on P-h diagram;...

In a vapor-compression refrigeration cycle, ammonia exits the evaporator as saturated vapor at -22°C. The refrigerant enters the condenser at 16 bar and 160°C, and saturated liquid exits at 16 bar. There is no significant heat transfer between the compressor and its surroundings, and the refrigerant passes through the evaporator with a negligible change in pressure. If the refrigerating capacity is 150 kW, determine: (a) the mass flow rate of the refrigerant, in kg/s. (b) the power input to the...

In a vapor-compression refrigeration cycle, ammonia exits the evaporator as saturated vapor at -22°C. The refrigerant enters the condenser at 16 bar and 190°C, and saturated liquid exits at 16 bar. There is no significant heat transfer between the compressor and its surroundings, and the refrigerant passes through the evaporator with a negligible change in pressure. If the refrigerating capacity is 50 kW, determine: (a) the mass flow rate of the refrigerant, in kg/s. (b) the power input to the...

4. A water chiller provides 100 tons 3.516 kw/ton of refrigeration to cool water to a temperature of 12.10 C for an air conditioning system. The heat extracted from the water is to be rejected in a cooling tower at 35.4°C, Assuming that the chiller operates on an ideal vapour refrigeration cycle with the temperature in the evaporator equal to the chilled water temperature and the saturation temperature in the condenser equal to the cooling tower water temperature, determine (a)...

In a vapor-compression refrigeration heat pump cycle with Refrigerant 134a as the working fluid provides heating at a rate of 15 kW to maintain a building at 20 °C year-round. During the heating mode in the winter, the outside temperature is 5 °C. It is also used for cooling in the summer when outside temperature is 34 °C. Saturated vapor at 2.4 bar leaves the evaporator and superheated vapor at 8 bar leaves the compressor. There is no significant heat...
