14-88 Atmospheric air at 1 atm, 32°C, and 95 percent rela- tive humidity is cooled to 24°C and 60 percent relative humid- ity. A simple ideal vapor-compression refrigeration system using refrigerant-134a as the working fluid is used to provide the cooling required. It operates its evaporator at 4°C and its condenser at a saturation temperature of 39.4°C. The con- denser rejects its heat...

Refrigeration Cycle Analysis In the refrigeration lab, a water bath is cooled to sub-ambient temperatures by using a refrigeration unit and a heater at the same time. The refrigerant used is R-290 (propane), with a density of 0.5 kg/L. The sight glass for measuring the refrigerant flow rate has a volume of 14...

The heat-pump system shown is designed to provide water-heating and space-cooling. The system includes a heat exchanger to subcool the R134a refrigerant at the outlet of the water heater while heating the refrigerant at the outlet of the evaporator. Given the following data, determine the enthalpy at each station, 1 through 6, using the R134a property tables (click here). Type your answers hy through h6 in the...

Q1): It is required to design a condenser that will be suitable for a refrigeration system that uses refrigerant 22 as the working fluid. The refrigeration system provides a refrigerating capacity of 50 kW for air conditioning purposes. At design conditions, the condensing temperature is 40°C while the evaporating temperature is 0°C. Cooling water enters the condenser at 25°C and leaves at 30°C. Design the condenser (calculate the required heat transfer...

Consider a concentric tube heat exchanger with hot and cold water inlet temperatures of 202 and 35°C respectively. The flow rates of the hot and cold fluids are 42 and 84 kg/h, respectively. Assume the overall heat transfer coefficient is 178 W/m2k. cc = 4186 J/kgk, ch = 4302 J/kgK What is the maximum heat transfer rate that could be...

Figure 1 presents a seawater cooled steam ejector refrigeration/Heat Pump System for Naval Surface Ship Applications. A Steam Ejector Refrigeration System is thermally driven heating and cooling technology by changing the pressure to control the boiling temperature which will enhance evaporation of fluid to realize cooling purpose. A heat pump system is to utilize the phase change of fluids to realize heating and cooling purpose. Please answer following questions: exhaust gas boiler nozzle section...
