Refrigerators, Heat Pumps, and Coefficient of Perfomance - Thermodynamics & Physics

This physics video tutorial explains how to calculate the coefficient of performance of refrigerators and heat pumps.  It explains how to calculate the mechanical work needed to transfer heat energy from the cold reservoir to the hot reservoir.  It also explains how to calculate the maximum coefficient of performance for a carnot refrigerator.  This thermodynamics video tutorial contains plenty of practice problems.
