Résumé

In the last years, international organizations undertook some actions with the aim to reduce anthropogenic CO2 emissions and to move towards a competitive low carbon economy. The European Union has recently drawn a new Regulation (No 517/2014) that prohibits the placement on the market of products and equipment after a specified date, according to the type or global warming potential of the fluorinated greenhouse gas contained. In order to comply with the abovementioned regulation different alternatives as hydrofluoroolefins (HFOs), hydrocarbons (HCs) and refrigerants blends are coming to the fore. In the present paper, the heat transfer performance during condensation and vaporization of these low-GWP refrigerants are reported. Since the refrigerant charge affects the risk associated with the use of HCs, an estimation of the charge in the heat exchanger is also presented.
