Summary

In this fifth part, the author deals with the problem of a group of refrigeration units combining various functions. Under the direction of a designated manager, an overall diagnosis is offered before any modification is proposed. This diagnosis may call into question the whole installation and lead to a more complete analysis on the in-depth retrofitting of the factory, or even reject it. This impartial diagnosis leads to a feasibility study based on energy savings and financial aspects, two inseparable aspects of any modern project.
