Abstract
(EN) Provided is an air-conditioning device comprising an outdoor unit that has a compressor and an outdoor heat exchanger and draws in outdoor air from outdoor space and discharges the outdoor air to the outdoor space, and an indoor unit that has a first expansion valve, a first indoor heat exchanger, and a second indoor heat exchanger and draws in indoor air from indoor space and discharges the indoor air to the indoor space, said air-conditioning device comprising: a second expansion valve that is disposed in the outdoor unit or the indoor unit; a refrigerant circuit that is configured by the compressor, the outdoor heat exchanger, the second expansion valve, the first indoor heat exchanger, the first expansion valve, and the second indoor heat exchanger being sequentially connected by piping; an adsorption/desorption device that has an adsorption member that adsorbs moisture from the air; and a controller that controls the opening degrees of the first expansion valve and the second expansion valve. The indoor unit has, formed therein, an air passage through which the indoor air drawn inside passes, and the first indoor heat exchanger, the adsorption/desorption device, and the second indoor heat exchanger are arranged in the air passage. The second indoor heat exchanger is disposed downstream of the first indoor heat exchanger. The adsorption/desorption device is disposed downstream of the first indoor heat exchanger and upstream of the second indoor heat exchanger. The controller controls the opening degrees of the first expansion valve and the second expansion valve, and has a cooling adsorption mode in which moisture in the indoor air is adsorbed by the adsorption/desorption device and a cooling desorption mode in which the adsorbed moisture is desorbed. The dehumidification control is performed by switching between the two modes.
(FR) L'invention concerne un dispositif de climatisation comprenant une unité extérieure comportant un compresseur et un échangeur de chaleur extérieur et permettant d'aspirer de l'air extérieur à partir d'un espace extérieur et d'évacuer l'air extérieur vers l'espace extérieur ; et une unité intérieure comportant un premier détendeur, un premier échangeur de chaleur intérieur et un second échangeur de chaleur intérieur et permettant d'aspirer de l'air intérieur à partir d'un espace intérieur et d'évacuer l'air intérieur vers l'espace intérieur. Ledit dispositif de climatisation comprend : un second détendeur disposé dans l'unité extérieure ou dans l'unité intérieure ; un circuit de fluide frigorigène formé par le compresseur, l'échangeur de chaleur extérieur, le second détendeur, le premier échangeur de chaleur intérieur, le premier détendeur et le second échangeur de chaleur intérieur, reliés successivement au moyen d'une tuyauterie ; un dispositif d'adsorption/désorption comportant un élément d'adsorption destiné à adsorber l'humidité de l'air ; et un dispositif de commande destiné à commander les degrés d'ouverture du premier détendeur et du second détendeur. L'unité intérieure contient un passage d'air apte à être traversé par l'air intérieur aspiré de l'intérieur, et le premier échangeur de chaleur intérieur, le dispositif d'adsorption/désorption et le second échangeur de chaleur intérieur sont agencés dans le passage d'air. Le second échangeur de chaleur intérieur est disposé en aval du premier échangeur de chaleur intérieur. Le dispositif d'adsorption/désorption est disposé en aval du premier échangeur de chaleur intérieur et en amont du second échangeur de chaleur intérieur. Le dispositif de commande permet de commander les degrés d'ouverture du premier détendeur et du second détendeur, et comporte un mode d'adsorption de refroidissement dans lequel l'humidité dans l'air intérieur est adsorbée par le dispositif d'adsorption/désorption, et un mode de désorption de refroidissement dans lequel l'humidité adsorbée est désorbée. La commande de déshumidification est effectuée au moyen de la commutation entre les deux modes.
