Description

Title of the invention: Permanent self-adapting air filtration and purification module intended to be inserted in place of a disposable filter.

[0001] The present invention relates to a permanent air treatment module intended to be installed in place of a disposable filter in a ventilation, air conditioning or heat pump system.

[0002] Disposable filters cause a progressive increase in pressure drop, a decrease in air flow and an increase in the electrical consumption of the blowers, resulting in a degradation of the energy performance coefficient of the associated systems.

[0003] The invention proposes a module comprising a permanent metallic filter medium, self-cleaning means and means for dynamic adaptation of the aerodynamic resistance, allowing to maintain an optimized airflow over time.

[0004] The pressure loss AP of the module is defined by the relation: AP = K • (p / 2) • v2, in which K represents the pressure loss coefficient, p the air density and v the air flow velocity.

[0005] The dynamic reduction of the pressure loss allows a decrease in the power absorbed by the blower and an improvement in the coefficient of performance COP of the thermodynamic system.
