In the world practice, there is a common and complex multifactorial indicator of the effectiveness of the equipment OEE (Overall Equipment Effectiveness). The major component of this indicator is the energy efficiency. Its significant reserve increase is in the refrigeration technology development and application of absorption thermotransformers. For qualitative assessment the use of thermodynamic analysis is requiredto ensure quality characteristics obtaining. These methods include entropy and exergy analysis. Thermodynamic analysis makes it possible to obtain the basic indicators of the processes in the various absorption lithium bromide refrigeration machines schemes. The overall objective of the work is to develop a methodology for assessing the thermodynamic efficiency of absorption lithium bromiderefrigeration machines (ALBRM) of new a generation over a wide range of operating parameters. As the results for this work a program has been written that allows one to conduct this assessment and get the best option for real ALBRM operating modes.
