Experimental results of transcritical CO2 refrigerator using an air cooling evaporator.
Author(s) : APREA C., ROSSI F. de, MAIORINO A.
Summary
The main purpose of this study is to investigate about the energetic performances of a transcritical CO2 refrigerator working as classical "split-systems" to cool air in residential applications. The design and construction of the refrigerator is shown and experimental results of the investigations carried out are presented. The CO2 system uses aluminium heat exchangers, a semi-hermetic compressor, an expansion valve and suction line heat exchangers. The performances measured in terms of COPs show a decrease respect to the "split-system" working with the HCFCs at the same external and internal conditions. Further improvements regarding the components of the cycle are necessary to use in large scale the "split-systems" working with the carbon dioxide.
