System and method for air handling and air conditioning

Abstract

A system for air handling and air conditioning to supply cool air inside a volume, the system including at least one enthalpy exchanger module including a dual airflow, enabling a heat transfer and a water vapor transfer between both airflows, the system configured to operate according to a cooling mode of the volume in which both airflows are respectively made of an outside airflow to be introduced into the volume, and a cooler dryer foul airflow, coming from inside of the volume. The system further includes: a mechanism enabling relative humidity of the outside airflow at an inlet of the enthalpy exchanger module to be determined; and a controller configured to command a heat supply to the outside airflow before it enters the module, when the relative humidity thereof exceeds a predetermined value.
