Of gaining ·! e refers to water supply and concerns the constructive performance of an autonomous installation for receiving water from humid air.

The purpose of the invention is to increase the efficiency of obtaining water pz humid air.

Pa figure 1 shows a stand-alone installation for obtaining water from humid air, a general view; Fig.2 installation diagram.

Offline installation of the day of receiving water from humid air contains placed on the rotary support 1 with the possibility of orientation in the direction of air movement condensing surface made in the form. the evaporator 2 of the refrigerating machine, in the lower part of which there is a tank 3 for collecting condensate, a cooling system made in the form of the condenser 4 of the refrigerating machine connected through compressor 5 by pipe b for circulating the refrigerant to the evaporator 2 and installed behind the evaporator 2 along the dried air .

Before the evaporator 2 on the rotatable support 1 mounted wind turbine 7 which is kinematically connected to a compressor 6 of the chiller, wherein the wind turbine 7, an evaporator 2 and a condenser 4 accommodated in general _hours duct 8 provided at the inlet with confuser 9 and having in the zone capacitor placement 4 ejector slit 10, with the possibility of changing the position along the smallpox of the duct 8,

The evaporator 2 and the condenser 4 are made with vertically arranged plates, facing to the inlet of the duct 8. The wind turbine 7 is connected to the compressor 5 through an additionally installed electric generator (not shown).

The evaporator 2 has on both sides condensate sloping channels .11 with an increasing cross-section from top to bottom, directed at an acute angle to the vertical towards the wind turbine 7. The air duct is provided with a vane rigidly connected with it (not shown).

The installation works as follows.

Before starting the installation, the installation is pre-positioned in the direction of external air movement, after which the installation independently orientates the confuser 9 of the air duct 8 towards the air flow using, for example, a weather vane.

The outside air enters the confuser 9 of the air duct 8, runs over the working element of the wind turbine 7, using which the energy of the air pressure is converted into mechanical (or electric) and then transferred to the compressor drive

After passing wind turbine

7, air flows through the duct 8 to the evaporator 2, where, in contact with its condensing surfaces, the air is dried and cooled.

Moisture released from the air flows from the vertical plates located mainly along the condensate discharge sloping channels 1.1 down into the condensate collecting tank 3. Running the condensate drain channels at an acute angle to the vertical towards the wind turbine 7 reduces the aerodynamic resistance in the evaporator 2 and an increase in the heat transfer coefficient of the condensing surfaces as a result of the intensification of the process of removing the moisture extracted from the air from the condensing surfaces. the upper levels.

From the evaporator 2 dried and cooled air enters by air. 1484886

the air to be heated to a temperature below the dew point temperature of the air, while the refrigerant heats up and enters the vapor state. From the evaporator, 2 pairs of refrigerant agent are pumped by compressor 5 through pipeline 6 to condenser 4, where they are cooled by the cooled air coming from the evaporator 2, and through the ejector slots 10 by outer 20 air.

From the condenser 4, the cooled refrigerant through the control valve (not shown) through the pipeline 6 again enters the evaporator 2. 25

To create the possibility of regulating the operation of the refrigerating machine in the nominal mode, the heat removal from the condenser 4 can be regulated by changing the flow rate and the point of supply through the adjustable ejector slots 10 to the outdoor air condenser 4.

In addition, control valves can be installed at the entrance or exit of the duct 8 (not yet. *

Zan), which may change the flow of air entering the duct 8 through the confuser 9 external air.

The use of the invention allows 40 to obtain moisture from the air without using for this any additional energy sources, provides full autonomy and high efficiency of the proposed installation.
