Abstract: The heat and mass exchange (HMX) module comprises a plurality of plates in a spaced-apart arrangement and provided with a plurality of air channels for air flow and a plurality of liquid channels for flow of liquid, wherein a liquid channel is embodied at a surface of a plate and is arranged adjacent to an air channel with a mutual exchange surface, which liquid channel is provided with an entry and an exit. The module further comprising a distance holder arranged between a first and a second adjacent plates. The entry of the liquid channel is defined as a plurality of entry regions spaced apart by means of closed regions, which entry regions define entry points for the liquid into and onto the layer of wicking material, in which closed regions the distance holder extends between the first and the second plate.

Abstract: The air-conditioning system comprises a dehumidification module and a regeneration module, that are arranged such that a first flow of liquid desiccant material may run in a cycle between those. The system also comprises a first container for the liquid desiccant material for supply into the dehumidifier module. Furthermore, the system is provided with a second regeneration module for generation of a second flow of liquid desiccant material and a second container for storage of desiccant material with an entry for the dehumidified second flow. It further comprises mixing means for mixing desiccant material from the second container into the first container and/or with the first flow upstream of the dehumidifier module.

Abstract: A heat and mass exchange (HMX) module comprising a plurality of plates in a spaced-apart arrangement and provided with a plurality of air channels for air flow and a plurality of liquid channels for flow of liquid, wherein a liquid channel is present on a surface of a plate and is arranged adjacent to an air channel with a mutual exchange surface, wherein the liquid channel is provided with a width extending substantially perpendicular to a flow direction in the liquid channel, further comprising means for setting a flow profile over the width of the liquid channel.

Abstract: The laminate comprising a first film of a polymer, a second film of a non-woven textile material, and a third film of a non-woven textile material, wherein the first film is arranged between the second and the third film, and wherein the second film and the third film of the laminate are provided with a corrugated surface provided with a plurality of ribs and valleys in a first direction, and a protrusion arranged in a direction at least substantially perpendicular to the said ribs and valleys. This may be created by thermoforming and for instance comprises a pattern of waves. The laminate is intended for use in an air-conditioner.

Abstract: The air-conditioning system comprises a dryer (10) comprising a membrane contactor (11) provided with a first channel (11b) for air flow and a second channel (11a) for desiccant flow, which channels are separated through a membrane (11c). The air conditioning system further comprises a humidifier (20) comprising a membrane contactor. The air flow passes in operation the dryer (10) and the humidifier (30) between an inlet (121) and an outlet (122). The dryer (10) comprises a series connection of a heat exchanger (12) and the membrane contactor (11), which heat exchanger couples air flow from the inlet (121) with desiccant flow from a regenerator (40) and in which membrane contactor (11) the thus heat-exchanged air flow and the heat-exchanged desiccant flow are coupled for drying of the airflow.
