The 5-ton AC unit designed in 13.2.5 reached 33% of the Carnot limit on CoP. Look back
Question:
The 5-ton AC unit designed in §13.2.5 reached 33% of the Carnot limit on CoP. Look back at the definition of the “Energy Efficiency Ratio” in Problem 10.12, which employs a different temperature range than the one we specified. Assuming that the unit’s fraction of the Carnot limit remains unchanged, compute its EER. How does this compare with the current US standard of EER ≥ 11.7?
