- Homework Statement
- A vapor compression refrigeration cycle uses R-22 and follows the theoretical single-stage cycle. The condensing temperature is 48 oC, and the evaporating temperature is -18 oC. The power input to the cycle is 3 kW, and the mass flow rate of refrigerant is 0.1 kg/s. Determine (a) the heat rejected from the condenser, (b) the coefficient of performance, and (c) the refrigerating efficiency.
- Relevant Equations
- R-22 table
Refrigeration system
Can efficiency be larger than 100%?
I have double checked the values of
enthalpy of point 1,2,3 from R-22 tables.
And I obtained enthalpy of point 4 from the work done given.
Thank you.
