A refrigerator uses R-134a as the working fluid and operates on an ideal vapor compression refrigeration cycle between 0.15 MPa and 1 MPa. Mass flow rate is 0.05 kg/s. If a minimum of 5 deg-C difference is used in the condenser design for effective heat transfer, what is the maximum value of the atmospheric temperature under this operating condition?
The Attempt at a Solution
No idea. Wouldn't it not matter since its atmospheric temperature? Or would it be the lowest temperature in the cycle?
