Refrigerants and compression refrigerating systems: the total equivalent greenhouse effect.

Frigorigènes et systèmes frigorifiques à compression : l'effet de serre équivalent total.

Author(s) : DUMINIL M.

Type of article: Article, Review, Case study

Summary

The influence of refrigerants on the environment is characterized by two notions: the ODP or stratospheric ozone depletion potential and the GWP or global warming potential. The measures aimed at reducing the negative effects due to refrigerant releases in the atmosphere are indicated. The energy consumption of a compression refrigerating unit in dependant on numerous parameters that are given in detail. A refrigerating system contributes to the greenhouse effect in two ways: direct release of the refrigerant into the atmosphere and CO2 release resulting from the unit's energy consumption. The TWI or total warming impact is a figure representing the total mass of CO2 (and equivalent CO2) en kilograms release into the environment by the operation of the refrigerating system over its lifespan. Two numeric examples are given: one represents a domestic refrigerator and the other a large sales display cabinet in France, in Germany and in Sweden, with, in each case, results obtained by varying the parameters.
