Performance comparisons for ammonia and carbon dioxide cold storage systems.

Number: 1070

Author(s) : PEARSON A., LAMB R.

Summary

Ammonia has traditionally been used as the refrigerant for large cold stores and freezers in many parts of the world with fluorocarbon refrigerants preferred for smaller installations. Recently, increasing environmental concerns have put pressure on polyfluorinated alkyl substances and have renewed interest in the application of carbon dioxide as a refrigerant, not only in smaller systems but also in the larger plants that had previously used ammonia. This paper outlines the key parameters to be considered when specifying an industrial refrigeration plant and shows which combination of factors might lead to the selection of carbon dioxide in preference to ammonia. Case studies showing relative performance and reliability for each type of system are presented and best practice guidelines for each option are developed. Finally the paper presents the consequences of making a wrong decision in terms of reliability, efficiency and full life cost.
