New Testing and Rating Procedures for Seasonal Performance of Heat Pumps
David Didion, George E. Kelly
It more efficient products are to be developed, it is essential that fair credit be given to as many energy conservation innovations as possible. In order to give such credit, and evaluation procedure is necessary which considers the causes of the inefficiencies, or stated in a positive sense, considers the modifications to the unit which will tend to minimize all the inefficiencies that may exist as operated in the field.
