Exergetic Analysis and Evaluation of Compression Refrigerating Machines and Heat Pump Processes.

Real refrigerating machines and heat pumps require much more driving power than would be necessary in a completely reversible process control by involving the environment. Exergetic analyses reveal the cause of losses. A detailed exergetic analysis is made of the single plant sections and the total process of compression refrigerating machines and compression heat pumps which is quantitatively supported by measuring results obtained from a cold water set. A presentation of the exergetic variables of the process in the T-S plot and a reference to the treatment of complete refrigerating plant and heat pump installations conclude the description.
