A refrigerator uses R−134a as its refrigerant and operates on an ideal vapour compression refrigeration cycle between 0.14MPa and 0.8MPa. If the mass flow rate of the refrigerant is 0.05kg/s, the rate of heat rejection to the environment is \(kW\).Given data :At P=0.14MPa,h=236.04 kJ/kg,s=0.9322 kJ/kgK At P=0.8 MPa,h=272.05 kJ/kg(superheated vapour)At P=0.8 MPa,h=93.42 kJ/kg(saturated liquid) |
