Abstract

The modern approach to cost calculation of the target product of the energy-transducing  systems is based on the application of the thermoeconomics principles. Thermoeconomics considers exergy flows as cost bearers. The end-product cost is connected with each stage of exergy transformation. The basic thermoeconomic models of cost formation of the cold produced by a vapor compression refrigerator are considered. For testing thermoeconomic models the uniform method of the cost analysis of the exergy flows was applied. The conclusion about the advantage of a negentropy approach to decomposition of the exergy flows with regard to the refrigerator analysis has been drawn.
