Patent number: 11512858Abstract: An air conditioning apparatus according to an aspect of the invention includes: an air conditioner that has a heat pump; a humidity controller of a wet desiccant type; an air transport flow path through which air discharged from the air conditioner is transported to the humidity controller; and a control unit that includes an air conditioner temperature control unit controlling a temperature of air discharged from the air conditioner and a humidity controller humidity control unit controlling a humidity of air discharged from the humidity controller. The air conditioner supplies the air, the temperature of which is controlled, to the humidity controller via the air transport flow path and the humidity controller discharges the air, the humidity of which is controlled, into a room.Type: GrantFiled: October 30, 2018Date of Patent: November 29, 2022Assignee: SHARP KABUSHIKI KAISHAInventors: Tetsuya Ide, Sho Ochi, Makoto Yamada, Hiroka Hamada, Jun Sakuma, Tsuyoshi Kamada

Publication number: 20220212140Abstract: Provided is a humidity control device capable of stably absorbing and desorbing moisture. The humidity control device includes: a moisture absorber causing a hygroscopic material to come into contact with air so that the hygroscopic material absorbs portion of moisture contained in the air, the hygroscopic material being in liquid and containing water, polyalcohol having hygroscopicity, and metal salt having hygroscopicity; and a composition controller controlling composition of the hygroscopic material. The composition controller controls the composition of the hygroscopic material to be within a range in which the hygroscopic material is capable of absorbing the moisture while the metal salt is kept from being deposited.Type: ApplicationFiled: April 16, 2020Publication date: July 7, 2022Applicant: SHARP KABUSHIKI KAISHAInventors: TETSUYA IDE, SHO OCHI, HIROKA HAMADA, TSUYOSHI KAMADA
