CEILING RADIANT COOLING SYSTEM BY COLD STORAGE/RADIATIONAL COOLING AND MOISTURE STORAGE/MOISTURE DESORPTION

摘要

PROBLEM TO BE SOLVED: To provide a radiant cooling system by cold storage/radiational cooling and moisture storage/moisture desorption, solving a temperature variation in a room and covering processing for a sensible heat load and a latent heat load in the room by midnight power.SOLUTION: This radiant cooling system by cold storage/radiational cooling and moisture storage/moisture desorption includes: a sealed ceiling space 4 defined between ceiling material 2 formed of moisture-permeable material and a skeleton slab 11 as a cold storage body above the ceiling material; an air conditioner 5 cooling and dehumidifying air in the ceiling space 4; and moisture conditioning material 54 storing and desorbing moisture in the air in the ceiling space 4. At night, the air in the ceiling space 4 is cooled by the air conditioner 5. Thereby, cold storage of the skeleton slab 11 is performed, and also the inside of the ceiling space 4 is dehumidified. In the daytime, the skeleton slab 11 subjected to the cold storage cools the ceiling material 2 by radiation and convection. Thereby, radiant cooling with respect to the inside of the room 3 is performed by the ceiling material 2, and also the moisture in the air in the room 3 permeates the ceiling material 2, is intruded into the ceiling space 4, and is absorbed by the moisture conditioning material 54.
