Embodiment Construction

[0028] Please refer to the attached figure 1 Shown, the present invention is further described.

[0029] As shown in the pattern,

[0030] When sunlight shines on the solar battery panel 1, the solar battery panel 1 charges the battery 3, and the solar battery panel controller 2 controls the charging current to protect the battery 3 from charging. In this example, the solar panel is 40W.

[0031] When the electric quantity in the storage battery 3 reaches the requirement. The semiconductor refrigeration sheet 5 is powered by the solar panel controller 2, and the solar panel controller 2 will control the current.

[0032] Under the action of electric current, the semiconductor refrigeration sheet 5 cools down rapidly at its cold end, and the temperature at the hot end increases accordingly. In this example, the semiconductor cooling chip is 33.4w, 30mmX30mmX3.2mm. Heat dissipation aluminum sheet 4 can be bonded on the hot end of semiconductor refrigeration sheet 5 with hea...

Abstract

The invention relates to a method for collecting water from the air. According to the principle that water vapour dissolution in the air is changed along with temperature, electric energy produced by solar-cell panel is utilized to supply power to a semiconductor refrigerating piece, the temperature of the cold end of the refrigerating piece is reduced under the action of current, when the temperature of a cold storage plate connected with the cold end is lower than the dew-point temperature of the environment, the water in the air is dewed on the cold storage plate.

Description

technical field [0001] The present invention relates to a method of collecting water from the air. Background technique [0002] The climate is warming, precipitation is decreasing, arid and semi-arid areas are expanding, and desertification is becoming more and more serious. Drought threatens people's survival and affects a variety of industries. [0003] At present, in response to drought, people usually exploit groundwater. However, with the development of society and the change of climate, the groundwater level keeps dropping. Moreover, limited by geological conditions, some arid areas have no groundwater for extraction. People need to find a permanent source of water. [0004] The air surrounds the whole earth, and the air on the earth is circular; the air contains moisture, and the amount of water vapor dissolved in the air changes with the temperature. One cubic meter of air can dissolve 9.41 grams of water at 10°C, and at 30°C Dissolve 30.38 grams of water. Und...
