Abstract[English]
A hybrid air conditioning system (100) for cooling a chamber (170), the hybrid system including a desiccant-coated heat pump (110) configured to cool, through evaporation and condensation of a refrigerant (140), a first air stream OA, and an indirect evaporative cooling, IEC, unit (160) configured to cool a second air stream MA, which is related to the first air stream OA, through direct heat exchange between wet channels (162) that are placed adjacent to dry channels (164). The desiccant-coated heat pump (110) is fluidly connected to the IEC unit (160) so that a generated supply air stream SA is dehumidified by a desiccant material (118, 126) coated on first and second heat exchangers (112, 120) of the desiccant-coated heat pump (110).[French]
L'invention concerne un système de climatisation hybride (100) pour le refroidissement d'une chambre (170), le système hybride comprenant une pompe à chaleur revêtue de déshydratant (110) conçue pour refroidir, par évaporation et condensation d'un fluide frigorigène (140), un premier flux d'air OA, et une unité (160) de refroidissement par évaporation indirecte, IEC, conçue pour refroidir un second flux d'air MA, qui est associé au premier flux d'air OA, par échange direct de chaleur entre des canaux humides (162) qui sont placés adjacents à des canaux secs (164). La pompe à chaleur revêtue de déshydratant (110) est en communication fluidique avec l'unité d'IEC (160) de sorte qu'un flux d'air d'alimentation généré SA est déshumidifié par un matériau déshydratant (118, 126) revêtu sur des premier et second échangeurs de chaleur (112, 120) de la pompe à chaleur revêtue de déshydratant (110).
