System-structural cycles analysis of refrigerating machines and heat pump installations
Keywords:
heat pump installation, refrigerating machine, criterion of the complexity, exergetic lossAbstract
On the basis of modern methods of applied thermodynamics method of system-structural analysis of the thermodynamic efficiency of refrigerating machines (RM) and heat pump systems (HP) been designed. To assess the impact of the structural complexity of the technological scheme of heat pump installations on its thermodynamic perfection the first time in the thermodynamic analysis of the criterion of the complexity of the scheme been introduced.By using the proposed method at the stage of the design analysis RM and HP depending on the structural complexity of the technological scheme the rational design characteristics of the heat exchange surface of the evaporator and condenser, piping of basic equipment can choose.Systemic laws of appearance of losses of irreversibility in the technological scheme of refrigeration and heat pump systems vapor compression type been identified.
