Abstract (Original Language):
Refrigeration is one of the technology sectors that has sufered the most changes in the last twenty years,
because of the negative impact of the fuids used in the refrigeration cycles, i.e., refrigerants, due to their
impact on the ozone layer and their contribution to global warming. As a result of their negative efects, the
European Union has established several directives to restrict the use of refrigerant fuids, and the sector
therefore needs to adapt to the new regulations.
This process of adaptation of the refrigeration sector to the new regulations must be carried out by all the
agents involved, including those engaged in the training and education of the future refrigeration technicians.
To allow this to be accomplished, a project called CO2LD was developed to introduce the future technology in
High Degree Professional Training in Refrigeration. The objective of the project consisted in introducing more
efcient and more sustainable refrigeration systems, namely R134a/CO2 cascade cycles, into the Advanced
Vocational Training in Refrigeration studies, and in creating a collaborative framework among students,
secondary schools, refrigeration technicians, refrigeration companies, and the University in order to facilitate
the transfer of know-how. This paper presents the objectives of the project, describes its development, and
analyzes its main conclusions.
