vapor compression refrigeration system operates on the cycle shown below (from Smith, Van Ness, and Abbott text). The refrigerant is tetrafluoroethane (P-H diagram from Smith, Van Ness, and Abbott text on next page). Determine the circulation rate of the refrigerant (in kg/s), the heat transfer rate in the condenser (in kW), the actual power requirement
A vapor compression refrigeration system operates on the cycle shown below (from Smith, Van Ness, and Abbott text). The refrigerant is tetrafluoroethane (P-H diagram from Smith, Van Ness, and Abbott text on next page). Determine the circulation rate of the refrigerant (in kg/s), the heat transfer rate in the condenser (in kW), the actual power requirement from compressor (in kW), the overall coefficient of performance of the cycle, and the coefficient of performance of a Carnot refrigeration cycle operating between the same temperature levels. Use the following operating data: Evaporation T = -10°C; Condensation T = 26°C; Compressor Efficiency Factor = 0.8; Refrigeration rate = 500 kJ/s.
