Mechanical Engineering
As a new engineer at CoolTech, you have been assigned to evaluate the performance of a cutting-edge refrigeration unit that uses R-134a as the working fluid. This unit operates on an ideal vapor compression cycle between 0.2 MPa and 0.9 MPa, and the mass flow rate of the refrigerant is 0.08 kg/s. Your task is to analyze the cycle and determine the following key performance indicators: (a) Calculate the rate at which the refrigeration unit removes heat from the refrigerated space. (4 pts) (b) Determine the power input required for the compressor. (3 pts) (c) Evaluate the heat rejection rate in the condenser. (3 pts) Bonus (1 pts) Compute the Coefficient of Performance (COP).
