WebUse Excel - Be organized. Use Excel formulas/functions. A new high efficiency motor is being considered for a large compressor. It will cost $22,000 but it will save $8250 per year in O&M. The useful life of the motor is 8 years. The company has a 3-year discounted payback period, and a MARR of 15%. (a) Should the motor be bought? WebThis heat pump therefore achieves 66% of the ideal limit. Note that we have not accounted for the efficiency of the electric motor that drives the compressor. Since motors are very efficient, the actual electrical power might be 2–3% higher than calculated in this example. 1.5.3. Thermodynamic efficiency of vapor compression refrigerators
