SYSTEME ET PROCEDE DE COMMANDE D'UN GROUPE MOTO-VENTILATEUR, NOTAMMENT POUR UNE INSTALLATION DE CHAUFFAGE ET/OU DE CLIMATISATION DE VEHICULE AUTOMOBILE

摘要

A method for controlling a motor fan unit (7) in a heating and/or air-conditioning facility comprising an inner heat exchanger (2), an outer heat exchanger (3), a compressor (4), an expander (5) and a refrigerant passing through these components and intended to exchange heat with a secondary fluid, said motor fan unit (7) facing the external heat exchanger (2). The method involves defining a minimum power to supply to the motor fan unit (7) in order for the refrigerant to reach the inlet of the compressor (4) in the gaseous phase.
