SOLVED: A refrigerator uses refrigerant-134a as the working fluid and operates on an ideal vapor compression refrigeration cycle between A and B. If the mass flow rate of the refrigerant is 0.04 kg/s and the specific work input to the compressor is 65 kJ/kg, determine: the rate of heat removal from the refrigerated space, the rate of heat rejection to the environment, and the COP of the refrigerator. Note that constant enthalpy process the expansion valve.Conversions: Properties of Saturated Ref

Consider a refrigerator that operates on the vapor compression refrigeration cycle with R-134 a as the working fluid. The refrigerant enters the compressor as saturated vapor at 160 kPa, and exits at 800 kPa and 50^∘ C, and leaves the condenser as saturated liquid at 800 kPa. The coefficient of performance of this refrigerator is (a) 2.6 (b) 1.0 (c) 4.2 (d) 3.2 (e) 4.4 | Numerade

SOLVED:An actual refrigerator operates on the vaporcompression refrigeration cycle with refrigerant-22 as the working fluid. The refrigerant evaporates at -15^∘ C and condenses at 40^∘ C. The isentropic efficiency of the compressor is 83 percent. The refrigerant is superheated by 5^∘ C at the compressor inlet and subcooled by 5^∘ C at the exit of the condenser. Determine (a) the heat removed from the cooled space and the work input, in kJ / kg and the COP of the cycle. Determine ( b ) the same p

A refrigerator operates on the ideal vapor-compression refrigeration cycle with refrigerant- 134 a as the working fluid. The refrigerant evaporates at -10^∘ C and condenses at 57.9^∘ C.The refrigerant absorbs heat from a space at 5^∘ C and rejects heat to ambient air at 25^∘ C. Determine (a) the cooling load, in kJ / kg, and the COP,(b) the exergy destruction in each component of the cycle and the total exergy destruction in the cycle, and (c) the second-law efficiency of the compressor, the eva
