Abstract

Un procédé de traitement d'air, visant à éliminer de cet air un brouillard givrant, brouillard givrant dont la présence est gênante pour un appareil ou système en contact avec cet air, se caractérisant en ce que : - on met en contact l'air avec un média filtrant (D, 1) apte à capter les microgouttelettes d'eau contenues dans l'air considéré ; - on procède à la régénération (M, 3) du média filtrant pour dégivrer et sécher ce média filtrant. Application à un système de refroidissement d'air utilisant un fluide cryogénique par l'intermédiaire d'un échangeur de chaleur (A) à convection forcée constitué d'un système de ventilation (V) et d'un échangeur de chaleur (G) « fluide cryogénique / Air », système tel une enceinte (E) climatique ou un camion frigorifique muni d'une enceinte (E) de stockage des produits transportés, système de refroidissement d'air qui comporte les éléments suivants : - Un système de filtration (F) placé sur l'aspiration d'air de l'échangeur de chaleur à convection forcé (A), apte à capter les micro-gouttelettes d'eau contenues dans l'air de l'enceinte aspiré par le système de ventilation (V); - Une enceinte de régénération (M) du système de filtration (M), apte à dégivrer et sécher le système de filtration.An air treatment process, aimed at eliminating from this air a freezing fog, freezing fog whose presence is troublesome for a device or system in contact with this air, characterized in that: - the air is brought into contact with a filtering medium (D, 1) capable of capturing the water microdroplets contained in the air in question; - Regeneration (M, 3) of the filter medium is carried out in order to defrost and dry this filter medium. Application to an air cooling system using a cryogenic fluid via a forced convection heat exchanger (A) consisting of a ventilation system (V) and a heat exchanger (G) " cryogenic fluid / Air ”, system such as a climatic chamber (E) or a refrigerated truck fitted with a chamber (E) for storing the transported products, air cooling system comprising the following elements: - A filtration system ( F) placed on the air intake of the forced convection heat exchanger (A), capable of capturing the micro-droplets of water contained in the air in the enclosure sucked in by the ventilation system (V ); - A regeneration chamber (M) of the filtration system (M), capable of defrosting and drying the filtration system.
