The invention relates to agriculture, in particular, to the plants to create a regulatory climate in livestock premises.

A device for sanitizing the air in livestock buildings, containing a duct mounted fans, heat exchanger, heater, thermal curtain, the connecting duct and tray for collecting condensate (SU # 1672137, 1991).

Part of the air along with the heat is removed, which increases the creation of optimal microclimate and requires high energy consumption.

The technical result consists in reducing energy consumption and increasing the level of treatment (microdisperse moisture and ammonia) internal air in the housing.

The technical result is achieved in that a device for sanitizing the air in livestock buildings, containing a fan and a duct, according to the invention, the duct is made of a triangular shape with an installed underneath a V-shaped metal shield mounted under the ceiling of the facility and connected to the mixing chamber with two air valves installed with the ability to work in automatic mode from a temperature sensor installed in the mixing chamber and the upper part of the duct is mounted on R which is 0.2 m from the ceiling.

In this device the inner oblojenny air smoooshed due to condensation microdisperse of air moisture on the outer surface of the duct, mounted under the ceiling of the room. Figure 1 presents a plan of the facility with a triangular suction duct, figure 2 - a section of the room with duct.

The device consists of a centrifugal fan 1 is attached to the suction duct triangular 2, mounted to the ceiling space of the animals. Under the duct 2 is mounted a V-shaped shield 3, which drains drip condensation moisture 4 on the outer surface of the duct 2 and is discharged into the sewer.

The upper part of the duct 2 is mounted at a distance of 0.2 m from the ceiling of the room. The ceiling mounted clamps 5 that secure the outboard duct 2 over the entire length of the room. On the triangular end of the suction duct 2 is installed mixing chamber 6 with an automatic air valve: internal 7 and 8 external air. Indoor animals are also mine 9 natural ventilation. Inside the mixing chamber is the sensor of the temperature controller 10. An additional mechanism 11 automatically adjusts the valves.

The device operates as follows. When the enable voltage is 1 and the outer air is sucked through the valve 8, as part of the interior through the valve 7. These valves are set to automatic and are driven synchronously from the actuator 11. Inside the mixing chamber 6 is the sensor of the temperature controller 10, which eliminates the freezing chamber 6 in the winter and regulates the temperature of the outer surface of the triangular duct 2, the temperature is constantly below the dew point temperature of the air surrounding the duct.

Therefore, continuously moisture condensation and absorption of ammonia from the air. Drip moisture absorbing ammonia, sliding on the outer inclined surfaces of the triangular duct in the V-shaped shield 3, which is installed under the duct and drains it into the sewer.

The device (almost 2-3 days) reduces the relative humidity of 55-60%, reduce up to 8-10 mg/m3the content of ammonia in the air and allows the HVAC system to operate in the recirculation mode of formation of the regulatory climate in livestock object and thereby to save up to 45-50% of energy for heating and ventilating a farm.

A device for sanitizing the air in livestock buildings, containing a fan and a duct, wherein the duct is made triangular is army installed underneath a V-shaped metal shield mounted under the ceiling of the facility and connected to the mixing chamber with two air valves installed with the ability to work in automatic mode from a temperature sensor installed in the mixing chamber and the upper part of the duct is mounted at a distance of 0.2 m from the ceiling.
