[Difficulty: 2]Problem 1.32Given:Equation for COPidealand temperature data.Find:COPideal, EER, and compare to a typical Energy Star compliant EERvalue. Solution:Use the COP equation. Then use conversions from Table G.2 or other sources (e.g., www.energystar.gov) tofind the EER.The given data isTL20273+() K⋅=TL293 K⋅=TH40273+() K⋅=TH313 K⋅=The COPIdealisCOPIdeal293313293−14.65==The EER is a similar measure to COP except the cooling rate (numerator) is in BTU/hr and the electrical input (denominator) is in W:
