A refrigerator operates between 120 kPa in an ideal vapour compression cycle withy R - 134a as the refrigerant enters the compressor as saturated vapour and leaves the condenser as saturated liquid. The mass flow rate of the refrigerant is 0..2 kg/s. Properties for R - 134a are as follows: || |---| | Saturated R - 134a| ||||||| |---|---|---|---|---|---| | P (kPa)| T (oC)| hf (kJ/kg)| Hg (kJ/kg)| Sf (kJ/kg. k)| Sg (kJ/kg. K)| | 120| - 22.32| 22.5| 237| 0.093| 0.95| | 800| 31.31| 95.5| 267.3| 0.354| 0.918| || |---| | Superheated R - 134a| ||||| |---|---|---|---| | P (kPa)| T (oC)| h (kJ/kg)| S (kJ/kg)| | 800| 40| 276.45| 0.95|
The rate at which heat is extracted (in kJ/s) from the refrigerated space is
