A refrigeration system for supermarkets using natural refrigerant CO2
This paper describes a refrigeration system using a natural refrigerant that has been developed to reduce significantly both direct and indirect greenhouse gas emissions. The new system uses both R-404A and CO2 (R-744) as refrigerants. The new system has very low global warming potential compared with conventional HFC systems which reduces significantly direct emissions. Indirect emissions are also much reduced as the system efficiency is much greater than achieved using conventional HFC refrigeration. The paper firstly describes an experimental system that has been used to demonstrate the new technology. It then compares the relative efficiency, operating cost and greenhouse gas emissions from the new system with that from a conventional system. It can be seen that emissions are approximately 66% of those from a conventional installation.
