Résumé

Nowadays, due to the increasing climate change problem, the existing regulation in the refrigeration market is leading to an intense research on systems that use CO2 as an efficient alternative to fluorinated substances. In these systems, whose operation implies high working pressures, it has been demonstrated that the performance of transcritical cycles considerably improves when an additional subcooling is introduced after the gascooler.

This work presents a vapour compression refrigeration system that operates with CO2 and which utilizes thermoelectric technology in order to provoke the subcooling. To that purpose, a computational model has been developed including, not only the vapour compression system, but also the subcooling system formed by a thermoelectric cooler. The obtained results show that the global COP of the system can be improved up to the 13.3 % and increments of 28.5 % in the cooling power can be achieved by means of thermoelectric subcooling.
