Optimisation expérimentale d’un cycle de Brayton inversé pour les applications de cryothérapie.

Experimental optimization of a reverse Brayton cycle for cryotherapy applications.

Résumé

A reverse Brayton cycle (RBC) using room air has been developed and tested under cryotherapy conditions, demonstrating a competitive coefficient of performance (COP) compared to cryogenic Rankine cycles. With no environmental impact or regulatory risks, this cycle offers a low-CAPEX, long-term investment option. Experimental data reveal key factors affecting COP and insights into the cycle of industrialization, maintenance, and operation challenges for cryotherapy. The cycle provides a fast dynamic response and stable performance under thermal loads and temperature variations. Economically, it benefits from low maintenance, no fluid costs, and low operational risk due to pressures below 5 bar (A). Key challenges include managing water freezing, condensates, and turbomachinery lubrication.
