Available energy method for evaluating thermodynamic performance of heat pump systems
Abstract
An available-energy-efficiency method, based on the Second Law of Thermodynamics, is developed for the evaluation and comparison of the thermodynamic performance of different types of heat pump systems. Defficiencies and limitations of the more commonly used performance indicators, coefficient of performance and fraction of Carnot cycle coefficient of performance, are discussed. Finally, several heat pumps of different types and in various stages of development are evaluated and compared in terms of available-energy efficiency as examples of the application of the method.
