Description

 The device relates to the field of water supply, namely to means for extracting water.

 The urgent need for fresh water of all sectors of life forces for the transfer of water resources, desalination of sea water and other expensive activities.

 It is known to extract water from the air [1] using the natural precipitation of dew from the air. The disadvantage of this device is its low productivity (1 liter of water per day) due to the limited ratio of temperature ratios required for the dew point in natural conditions.

 In the device [2], the required temperature ratio is maintained artificially through the use of a refrigeration machine.

 The disadvantage of this device is the need to expend a significant amount of energy for the operation of the refrigeration machine, often exacerbated by the lack of electricity in places of severe moisture deficiency.

 The objective of the present invention is to reduce the energy intensity of water from air. The technical result is achieved by the fact that in the installation for receiving water from air containing a vertical duct, a water collector, heating and cooling elements of the chiller, the cooling element is made in the form of a cylinder, which is placed in the central part of the duct channel, the heating element is made in the form of a truncated cone and placed on the outer casing, between the cooling and heating elements, a separation cup made of insulating material facing the open side is installed a, the glass is placed with the formation of two annular cavities - expanding downward one between the cooling element and the glass and the other between the glass and the heating element.

 Such use of elements known in the art required fundamental structural changes of devices, in connection with which the claimed proposal meets the criterion of "inventive step".

In fact, the above signs exhibit new, previously unknown properties, namely:
the implementation of the cooling element in the form of a cylinder ensures its greatest heat absorption due to the flow around the air from both inside and outside;
the use of structural elements of a conical shape provides a change in the volume of air (its density) in the direction of travel: in the cooling zone, the cross section is expanded, in the heating zone is narrowed, which, in accordance with the Boyle-Mariotte law, helps to cool the air in the zone of the cooling element and heat in the zone of the heating element;
the change in the living cross section of the air flow in the direction of its movement leads to turbulization of the air, which contributes to a uniform change in temperature;
the installation of a heating element on a conical-shaped casing ensures its position close to the front in relation to the Sun at any time of the day, which contributes to its better heating.

 The invention is illustrated by the drawing, in which the cooling element 1 in the form of a cylinder is installed in the glass 2 open from the bottom, made of heat-insulating material, and placed, in turn, in a conical-shaped casing formed completely or partially (from the side of the Sun) by the heating element 3.

 In the upper part of the casing, adapter 4 connects it to the vertical duct 5. Cooling 1 and heating 3 elements of the chiller are connected by functional blocks 6 (absorber, condenser, thermostatic valves).

 The lower part of the ducts is closed by a pallet 7 having a drain pipe 8 in the lower part. A water tank 9 is installed under the latter. Supports 10 provide the necessary pressure regime of water use, access to sunlight and protection from outside interference.

 The device operates as follows.

 Due to the heating of the heating element 3 and the duct 5 by the Sun, traction occurs in the latter. The air coming from below into the cooling element 1 is cooled to the dew point, the condensate falls on the tray 7, and the air heated also from the heat generated by moisture condensation goes higher through the adapter 4 into the duct 5. In this case, the air flowing around the separation cup 2 lengthens the path for cooling the air , and also serves as a place of moisture condensation, from where it flows onto the pallet. The nodes 6 of the refrigeration machine ensure its operation. From the pallet 7, water flows through the drain pipe 8, the hydraulic lock of which prevents air from entering the pipe, flows into the storage tank 9, the position of which under the pipe is provided by the supports 10.

 Thermal energy calculations show high efficiency of water production. At the same time, energy costs in regions with a complete absence of its traditional sources are significantly less than for distillation of sea water by evaporation.
