Abstract

Reported about a method for conducting a structural analysis of the thermodynamic refrigerating machine on the basis of separation exergy of destruction on the external and internal independent parts, as well as removable and its components are inevitable. The methodology has allowed complex take into account the influence on the efficiency of the refrigerating machine thermal-hydraulic losses and estimates the components of the exergy destruction in the basic elements. The analysis of characteristics of the refrigerating machine showed that over 50 % of exergy destruction in the compressor is connected with inefficiency neighboring elements of the scheme. In the condenser the exogenous component of exergy destruction does not exceed 30 %. More than 98 % of the exergy destruction in the evaporator makes its an endogenous part.
