Embodiment Construction

[0041] figure 1 The shown atmospheric moisture water generator 2 comprises a centrally located tower flue 4 surrounded by a heating enclosure 6 that collects incident solar energy to heat the air entering its periphery 8 . Due to the heating of the air in the heating enclosure 6, an updraft is generated in the tower 4 as the air returns from the heating enclosure 6 from the open end of the tower to the atmosphere. Around the base of the tower there is a base structure 10 housing a plurality of wind turbines. The flow of hot air from the heated enclosure 6 into the tower is controlled to turn the wind turbine. As described below, each wind turbine has a corresponding water collection device that includes a refrigeration system that cools the condensation surface to the dew point of the air or below, so that the moisture in the air is condensed on the condensation surface of the water collection device and collected . The refrigeration system includes a compressor driven by a...

Abstract

The atmospheric water harvester (2) shown in fig (1) comprises a centrally located flue in the form of a tower 4 and a surrounding heating enclosure (6) for collecting incident solar energy to heat air which enters its periphery (8). With heating of the air in the heating enclosure (6), an updraught is created within tower (4) as the air from the heating enclosure (6) returns to the atmosphere from the open end of the tower. A base structure (10) housing a plurality of wind turbines is provided around the base of the tower. As the heated air flows from the heating enclosure (6) into the tower it is harnessed to rotate the wind turbines. Each wind turbine (20) is provided with associated water collection apparatus (94) comprising a refrigeration system for cooling condensation surfaces to, or below, the dew point of the air to effect the condensation of water from the air onto condensation surfaces of the water collection apparatus for collection. The refrigeration system comprises a compressor (46) for compressing a refrigerant vapour for the cooling of the condensation surfaces and which is driven by the wind turbine (20).

Description

technical field [0001] The invention generally relates to condensing moisture in the atmosphere to provide a water source, in particular to a solar water generator that uses atmospheric moisture to produce water. Background technique [0002] Changing climate patterns and increased global pollution mean water scarcity is a major problem. Therefore various organizations and governments all over the world are designing various methods and equipment for saving water and producing drinking water. [0003] One of the problems with many existing water production methods is the need to power the potable water production facility. This is especially the case with known water desalination plants using reverse osmosis technology. These methods have two disadvantages, namely the production of pollution including greenhouse gases and high operating costs. [0004] In the past 15-20 years, pollution-free solar tower power plants using solar power have been proposed as an alternative t...
