Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2014194327
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To relax temperature change in a space year-round, and to eventually enable reduction in energy used in the other heating apparatuses and other cooling apparatuses and contribution to energy saving.SOLUTION: Each of a first heat reservoir 1 and a second heat reservoir 2 includes a principal surface that is a floor surface 21 dividing an indoor space 8, and transmits heat accumulated by heat exchange with air passed therethrough to the indoor space 8 through the principal surface. As a latent heat storage medium of the first heat reservoir 1, a material lower in phase change temperature than a latent heat storage medium of the second heat reservoir 2 is selected. The first heat reservoir 1 is arranged in a region irradiated with solar radiation in winter whereas the second heat reservoir 2 is arranged in a region that is not irradiated with the solar radiation in summer. A control device 6 switches a state over among a state in which the heat stored in the first heat reservoir 1 by the solar heat from the principal surface is emitted into the space 8 in a time zone in which the first heat reservoir 1 is not irradiated with the solar radiation, a state in which a channel for passing the air outside of the space 8 through the second heat reservoir 2 and storing cold therein, and a state in which the cold stored in the second heat reservoir 2 is emitted into the space 8.
