2. A freezer with a capacity of 180 kW is needed for a food processing plant. The required cooling will be provided by an ideal vapor-compression refrigeration cycle with its evaporator at 320 kPa and its condenser at 1.4 MPa. If the refrigerant used in the cycle is R-134a, show the cycle on the T-s diagram with respect to saturation lines and determine, a) the mass flow rate of the refrigerant, b) the required compressor power, c) the COP of the cycle.
