THERMODYNAMIC EFFICIENCY OF NON-ELECCTRICALLY DRIVEN REFRIGERATION MASHINE
Abstract
This work shows some research in the field of thermal refrigeration machines on the possibility of using waste heat from various industrial productions. The utilization of waste heat and secondary energy resources from power plants and technological processes in industrial enterprises with different temperature levels is also one of the main conditions for saving energy carriers. For refrigeration equipment, as one of the most energy-intensive sectors of the economy for any country, the prospect is the improvement of refrigeration machines, with the expanded possibility of using any type of heat, combined with the creation of new solutions for circuit cycles, contributing to reducing their energy dependence.
A comparative exergy analysis of the different types was made and a methodology was proposed for determining the degree of thermodynamic perfection necessary for determining the energy efficiency of the installations.
