Abstract

When designing the systems of refrigeration for fruit and vegetables stores it is necessary to do a thermoeconomic analysis of the object being created for resolve the problem of today to save energy taking into account price changes of electric power. A thermoeconomic model of a refrigerating plant to provide with cold the fruit and vegetable stores. The model takes into account the exergy indexes and losses as the components of criterion of thermodynamic efficiency of energy systems providing minimum of costs cited. Thanks to the model an analytical solution has been obtained on the basis of which the optimal characteristics of the cold supply system and conditions of it exploitation were defined. Keywords: refrigerating plant, fruit and vegetable store, exergy, thermoeconomic model, optimization, electric power prices
