The invention relates to agriculture, in particular to methods for making optimal microclimate on farms and can also be used for dehydration of the air in rooms of bath and Laundry plants.

There is a method of sanitizing the air in livestock buildings, including the supply of outdoor air, the mixing of external and internal air, receiving condensate and collect it in the tray, located under the heat exchanger, air heating and dehumidification [1].

For reasons that impede the achievement of specified following technical result when using this method include increased energy consumption for heating the incoming outside air and the removal from the air of considerable heat.

There is also known a method of sanitization of air in the housing, including submission of external and internal air through the duct triangular-shaped cross-section, the formation of condensation on it and its collection into the sewer through a V-shaped visor, fixed under the duct [2], adopted for the prototype.

For reasons that impede the achievement of specified following technical result when using the known method, taken as a prototype, is that in the known method the condensation duct tre the verbal form of the cross section occurs due to the presence in the air a certain number of centers of condensation, i.e. dust, smoke particles, etc. floating in the atmosphere, and entirely dependent on the amount of internal air space, which is not sufficient for timely and guaranteed dehydration of air to a valid sanitary standards, as well as launch together with the condensate impurities.

The invention consists in the use of the ability of electric charges to accumulate on the edges and sharp edges of the conductors and to ionize the air around points for artificial obtain near duct ions, i.e. an additional number of new nuclei of germ droplets, due to the use of metal visor for collecting condensate Crescent-shaped form with sawtooth projections on the lateral edges along its length and message him of electric charge.

In particular, the supply of Crescent-shaped visor-shaped cross-section sharp sawtooth projections on the lateral edges facing the triangular duct, and submission to it of the electric charge leads to an increase in charge density on the edges, and hence increase the strength of the electric field near the points where these fields reach a large size, which causes ionization of air molecules and the ions of different sign near each edge, in this regard, in the space between the duct is Crescent-shaped visor, in addition to the existing centres of condensation on ions new germ droplets, i.e. additional centers of condensation, which activates the process of dehydration and clean the inside of air contaminants entering in connection with the condensate.

The technical result is the acceleration of the process of condensation of moisture from the indoor air and the removal from it of harmful impurities.

This technical result in the implementation of the invention is achieved in that in the known method of sanitization of air in the housing, including submission of external and internal air through the duct triangular-shaped cross-section, maintaining the outer surface of the duct below the dew point temperature of the interior air, the formation of condensation on it and its collection into the sewer through the V-shaped shield secured under the duct, hood for collecting condensate made of a metal conductor sickle-shaped cross-section with sawtooth projections on its lateral edges facing the triangular duct, and connected to a source of direct electric current.

The acceleration of the process of condensation and cleaning the inside of the air duct triangular-shaped cross-section occur due to the emergence of ions near it, on razuysya on the sharp edges of the canopy to collect condensate sickle-shaped cross-section, which attract the vapor molecules and form tiny droplets that serve as centers of further condensation.

The proposed method is illustrated by drawings.

In figure 1, 2 represents the diagram of an animal breeding facility located in it with duct triangular-shaped cross-section and is suspended underneath Crescent-shaped visor for collecting condensate with a sharp sawtooth projections on the lateral edges connected through a rectifier to a source of electric current.

Information confirming the ability of the invention to provide the above technical result.

The method is as follows. The mixture of warm wet recirculation and external cold air under the pressure of the suction fan is inside the triangular duct 1, is installed under the ceiling of the livestock building 2, and constantly supports on the outer surface of the duct 1 temperature below the dew point of the inside air.

Dehydration internal air is realized by obtaining condensate 3 of air farm on the outer surface of the triangular suction duct 1, and collecting and transporting it into the sewer through the metal Crescent-shaped visor 4 hanging from the duct 1 in the electrically insulating bracket is 5 (for example, from rubberized belt).

Condensate 3 get on the nuclei of germ droplets, which along with dust particles, smoke, etc. are ions of different sign, formed near sharp edges 6 Crescent-shaped visor 4, charged from the positive terminal (terminal 7) of the rectifier 9 is connected to the household electrical network with earthed negative pole (terminal 8).

When the message is isolated from the earth to the sun visor 4 electric charge by connecting it to terminal 7 of the rectifier 9, the charge density due to the peculiarities of their distribution on the surface of the conductor, substantially independent of the shape of its surface, will be the largest on the sharp protrusions 6 Crescent-shaped visor 4, where the electric field intensity is particularly high, which causes ionization of the air molecules near sharp edges 6 and even the emergence of "ion wind", the intensity of which depends on the voltage supplied.

Flow in the space between the Crescent-shaped visor 4 and the duct 1 triangular cross-section sufficient number of nuclei of germ droplets in the form of ions with a different sign, coming from points 6 located on the side of the sawtooth edges of the visor 4, accelerates the process of condensation of water from the internal air of the facility and facilitates its purification from the Reden impurities, output from the condensate.

Thus, the presented data suggest the implementation of the use of the claimed invention (method) the following cumulative conditions:

- means for its implementation is intended for use in agriculture, namely the creation of optimum microclimate on farms, in particular, clean the inside of the air in livestock buildings from moisture and contaminants;

for the inventive method, it is described in the independent clause sets out the claims, confirmed the possibility of its implementation using the steps described in the application or known before the priority date tools and methods.

Therefore, the claimed invention meets the condition of "industrial applicability".
