Document Type and Number:
WIPO Patent Application WO/2023/025664
Kind Code:
A1
Abstract:
A system (1) for cooling a refrigerant (R) for an aircraft comprising a plurality of ducts (2) for circulating the refrigerant (R) that are configured to be at least partially in contact with an airflow (A) so as to cool the refrigerant (R) through convection, the cooling system (1) comprising a safety heating device (3) extending internally inside at least one portion of the circulation ducts (2) so as to heat the refrigerant (R), a member (4) for measuring a physical parameter of the refrigerant (R) according to the flow rate of the refrigerant (R) in the circulation ducts (2) and a control member (5) configured to activate the safety heating device (3) when the measured physical parameter is below a predetermined threshold corresponding to a minimum flow rate of the refrigerant (R) in the circulation ducts (2).
