▎ 摘　　要

NOVELTY - Water collecting device based on metal-organic framework (MOF) material comprises radiation refrigerating film (1), conversion chamber (2), solar reflection film (3), heat conducting plate (4), MOF adsorbing material (5), heat medium chamber, water collecting chamber, cooling medium chamber, water tank, movable clapboard, temperature sensor, first piston, second piston, first valve rod, second valve rod, first valve, second valve, pressure regulating valve and exhaust valve. The bottom of radiation refrigerating film is closely connected to top of conversion chamber. The heat medium chamber is connected to conversion chamber through first pipeline. The MOF adsorbing material is connected to water collecting chamber through third pipeline. The heat medium chamber is connected to output end of first valve through fifth pipeline. A fourth pipeline fills heat medium chamber with heat medium. A sixth pipeline fills cooling medium chamber with cooling medium. USE - Used as water collecting device based on MOF material. ADVANTAGE - The device: combines MOF adsorption material with radiation refrigeration technology and solar heat collection technology; obtains cold energy by heat exchange between radiation refrigerating film and outer space to improve adsorption performance of MOF materials; utilizes heat medium to improve absorption capacity of MOF materials to solar heat radiation; and improves desorption performance of MOF materials and ability of MOF materials to absorb moisture in air while fully utilizing natural ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a water collecting method based on MOF material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the water collecting device based on MOF material. 1Radiation refrigerating film 2Conversion chamber 3Solar reflection film 4Heat conducting plate 5MOF adsorbing material
