The ECOFROID patent.



This article presents a refrigerating circuit using a halogenated refrigerant fluid (non-specific), enabling low condensation temperatures to be used in winter. The condensed refrigerant is expanded twice. The first time, the fluid is expanded from condensation temperature to up to 20 deg C, while the second time it is expanded from 20 deg C to evaporating temperature. Expansion valves are adjusted in the most advantageous manner all year round.
