Abstract: A dual air flow exchanger, allowing a heat transfer and humidity transfer between two air flows, and including a plurality of first and second air circulation networks separated by membranes permeable to water vapor and impermeable to air and to liquid water, each of the first and second networks including cells each defined by a wall including openings for passage of air, the cell wall including two opposing edges at which same is open in a direction of stacking. For at least one of the first networks, at least one of the two opposing edges of each cell wall defines a hollow open in a direction of the second directly consecutive air circulation network, the hollows receiving a part of the second network.

Abstract: A concentrating solar module comprising a device (D) for managing the moisture contained in a casing (2) of the module (M). The device comprises a housing (12) one of the walls (14) of which is provided with a window (15), a moisture absorbing material provided in the housing (12), a shield (28) provided facing the window (15) and distant therefrom so as to provide a space for the air flow between the window (15) and the shield (28), the shielding means (28) protecting the absorbing material from the concentrated solar radiation. The device is attached to a side wall (4) of the casing (2) such that said window (15) faces an aperture (16) provided inside said side wall (4) ensuring with said window (15) a fluid communication with the internal volume of the module and the shielding means (28) being located inside the solar module (M).

Abstract: A solar module in a concentrating solar system including: a box including a top wall, formed from an optical system, and walls; at least one photovoltaic cell placed in the box; and at least one humidity management device. At least one first wall among the walls includes a principal part contained in a plane. The humidity management device includes a housing defined between the first wall and a cover fixed to the first wall including an occultation part and an inner part forming an air film at the occultation part. A moisture-absorbing material is placed in the housing, at least part of the moisture-absorbing material is located on one side of the plane containing the occultation part.

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.

Abstract: A dual air flow exchanger, enabling heat transfer and humidity transfer between two air flows, and including a plurality of air circulation networks stacked on each other along a stacking direction and separated in pairs by membranes permeable to water vapor and impermeable to air. At least one of the networks is made from a honeycomb structure with its two sides bearing on two of the membranes, the structure including cylindrical cells with axes parallel to the direction, and in which at least some of the cell faces are perforated to allow air passage.
