Dioxyde de carbone pour les supermarchés utilisant des puits thermiques à basse température : une étude de cas.

Carbon dioxide for supermarkets using low temperature heat sinks: a case study.

Auteurs : COLOMBO I., BUTLER A., GEBRAIL G., et al.


Carbon dioxide (R744) can be used as an alternative refrigerant to hydrofluorocarbons (HFCs) which are currently in widespread use. This can reduce the direct emissions of potent greenhouse gases from supermarket refrigeration plants. These applications are energy intensive and use large amounts of refrigerant; collectively they have a large environmental impact. Due to its thermodynamic properties, R744 provides real benefits when used in multistage refrigeration systems. Also, R744 which is not covered by the F-Gas regulation will reduce the running cost specifically by the avoidance of periodic inspection. This paper reports on work being carried out investigating the use of R744 in supermarkets. The energy usage and running cost of a typical supermarket system are described. It then describes how a novel R744 system may be incorporated and provides some generic calculations to identify the energy use by different systems. The economic and environmental performances of R744 systems are compared.
