On the basis of the available data on the use of refrigeration units with conventional artificial refrigerants, recommendations on CO2 are used when designing refrigerant machines to operate under various external conditions, efficient in terms of their thermotechnical, energetic, and performance characteristics. A comparative analysis of the cycle indicators of refrigerating machines using various refrigerants as the working substance is given. The comparison is made considering the type of cold supply facility, the temperature levels of cold consumption, and the external conditions for heat removal to the environment. The advantages of using natural refrigerant R744 in the cycles of the lower stage of refrigerating machines with semi-hermetic compressors are justified. [ABSTRACT FROM AUTHOR] |
