Refrigeranti naturali nel settore RACHP – Impianti e componenti

L’impiego di refrigeranti naturali nei cicli a compressione di vapore viene considerato una delle soluzioni necessarie per la sostenibilità dei sistemi RACHP, in grado di contribuire non solo alla mitigazione climatica (ODP e GWP) ma anche alla tutela degli ecosistemi e della salute (TFA, PFAS). La sfida consiste quindi nello scegliere il refrigerante naturale più adatto per ogni applicazione e nel realizzare la soluzione più efficiente ed economicamente sostenibile. Il ripensamento dei sistemi e dei componenti alla luce delle opzioni disponibili (ammoniaca, idrocarburi, anidride carbonica, acqua, aria), delle loro proprietà termofisiche  e di trasporto e delle caratteristiche di sicurezza è un altro passo fondamentale per il raggiungimento degli obiettivi di sostenibilità. L’attività di ricerca richiede una collaborazione continua con l’industria del settore.
