Title:
NOVEL THERMOCHROMIC INTELLIGENT WINDOW HAVING ADJUSTABLE EMISSIVITY
Document Type and Number:
WIPO Patent Application WO/2021/243847
Kind Code:
A1
Abstract:
A thermochromic intelligent window having an adjustable emissivity, comprising a window frame (1). A glass assembly (2) is provided inside the window frame (1); the glass assembly (2) comprises a glass substrate (21); a metal oxide coating (3) used for adjusting the glass substrate (21) to have a low-radiation function in a mid-infrared region is deposited on one side of the glass substrate (21); the metal oxide coating (3) is a layer of a transparent indium tin oxide film; a solar adjustment high-radiation portion (4) is provided on the other side of the glass substrate (21); the solar adjustment high-radiation portion (4) comprises a first polyethylene layer (41); a hydroxypropyl cellulose hydrogel layer (42) is provided on the upper portion of the first polyethylene layer (41); the hydroxypropyl cellulose hydrogel layer (42) is further provided with a second polyethylene layer (43); the hydroxypropyl cellulose hydrogel layer (42) is wrapped in the middle by the first polyethylene layer (41) and the second polyethylene layer (43). The intelligent window can dynamically adjust heat radiation and solar transmittance of different wave bands according to change of seasons and climate, thereby reducing an indoor temperature and energy consumption, and reducing the cooling load of a building in summer and reducing the heat loss in winter.
