Summary

Carbon dioxide is one of the earliest substances to have been used as a refrigerant. In the mid-19th century, when refrigeration technology was in its infancy, technicians used readily available substances, such as ether, sulphur dioxide, air, ammonia and carbon dioxide. Each substance had its advantages and disadvantages, and as compressor technology developed, ammonia came to dominate the early refrigeration market. The authors study the use of carbon dioxide instead of ammonia in food factory. A recent work in a UK factory has demonstrated the viability of carbon dioxide cascade systems for low temperature applications and provided the users with valuable experience of the various advantages and disadvantages of this fluid. Some further development needs to be done in the design and implementation of components and ancillary systems, but in all other aspects the technology is already proven, and is available for implementation now.
