Question

Problem 8. Consider the following refrigeration system: The working fluid is R-134a. The refrigerated space is maintained at \( -5^{\circ} \mathrm{C} \) by this system. The condenser is water cooled. \( 0.13 \mathrm{~kg} / \mathrm{s} \) of water enters the condenser at \( 20^{\circ} \mathrm{C} \) and leaves at \( 28^{\circ} \mathrm{C} \). Refrigerant enters the condenser at 1.2 MPa and \( 50^{\circ} \mathrm{C} \) and leaves as a saturated liquid. The compressor consumes 1.9 kW of power. Find: a) Refrigeration load, in BTU/h b) COP c) Second-law efficiency d) Exergy destruction and entropy generation of the full cycle
