A refrigerator uses refrigerant 134a as the working fluid and operates on a ideal vapor-compression refrigeration cycle between 0.1 and 0.6 MPa. The mass flow rate of the refrigerant is 0.08 kg/s. Show the T-s diagram with respect to saturation lines. Determine: 1. The rate of heat removal from the refrigerated space and the power input to the compressor. 2. The rate of heat rejection to the environment.
