Description

The invention relates to agriculture, namely, electrothermal heaters, designed to create the required microclimate parameters in the production rooms of livestock farms.

Known heat recovery installation "Febag" company "Gemmel" (Germany), an air heater for microclimate systems on livestock farms (AS USSR No. 1307167).

The disadvantages of the Febag heat exchanger and the air heater are their lack of devices for additional supply air heating, which is necessary for the unit to operate at low outdoor temperatures, the absence of a room indoor air recirculation system used to reduce energy consumption, a frost protection device for heat-exchanging surfaces of the heat exchanger, and a supply air cleaning system and exhaust air.

Closest to the technical nature of the present invention is an electrothermal recovery installation comprising supply and exhaust air fans, a small-sized heat exchanger made of polymeric materials, an air supply pipe, an exhaust and supply air ducts, an supply air electric heater installed between the supply fan and the air supply pipe, a recirculation channel, connecting the exhaust and supply air ducts through the damper (RF patent No. 2296463 of 08/08/2005).

The disadvantages of the prototype is its lack of a system of high-quality cleaning and disinfection of indoor air, which significantly limits the possibility of using indoor air recirculation due to its contamination and bacterial contamination as a result of animal activity, and thus the required air composition established by the technological design standards is not provided, in zone of animals. It is also necessary to clean and disinfect the air because a large amount of dust, microorganisms, and gases is carried out from the premises with ventilation air, which leads to environmental pollution. With a large dust content and a high content of microorganisms in the outdoor air, ventilation becomes ineffective.

The objective of the invention is to provide the required standards for technological design of livestock enterprises basic microclimate parameters (including the composition and purity of air) for various climatic zones of the Russian Federation while reducing energy consumption for heating the supply air and improving the environment.

As a result of using the present invention, it becomes possible to provide heating of the ventilation air in the coldest period of the year due to partial recirculation of the exhausted warm indoor air after its purification and disinfection by the ozonation method, which saves energy costs up to 30 ... 50%, significantly improves the gas composition of the supply and exhaust air, normalize the environmental situation around the livestock enterprise, increase efficiency and expand the scope electrothermal heat exchanger.

The proposed electrothermal heat exchanger with ozonation and air recirculation is designed to create and maintain the required microclimate parameters in the working area of the placement of animal production facilities of livestock farms.

The above technical result is achieved in that an electrothermal heat exchanger with ozonation and air recirculation, comprising supply and exhaust air fans, a small-sized heat exchanger made of polymeric materials, an air supply pipe, exhaust and supply ducts, a supply air electric heater, a recirculation duct with a damper, air purification filters, a distributor, supply air contains a corona discharge ozonizer mounted on the lower outer side of the housing of the supply pipe air with flexible ozone supply pipelines, and a recirculation channel mixing chamber, while the ozone supply pipelines are connected on one side to a corona discharge ozonizer, and, on the other hand, the pipelines are connected to the recirculation channel mixing chamber and the supply air distributor.

The invention is illustrated in the drawing, which shows a functional-technological scheme of the operation of an electrothermal heat exchanger with ozonation and air recirculation.

The electrothermal heater with ozonation and air recirculation includes a ventilating fan 1, a small-sized heat exchanger made of polymer materials 2, a supply air fan 3, a peak supply air heater 4, an air supply pipe 5, a supply air distributor 6, a fitting 7, a tee 8, flexible pipelines ozone supply 9, corona discharge ozonizer 10, exhaust air filter 11, supply air filter 12, supply air duct 13, recirculation channel 14 with a mixing chamber, in zdushnuyu damper 15, exhaust air duct 16.

Ozone supply pipelines 9 are connected on one side to a corona discharge ozonizer 10 using a nozzle 7 and a tee 8, on the other hand, using nozzles 7 they are connected to the mixing chamber of the recirculation channel 14 and the supply air distributor 6, in which ozone is disinfected and saturated with air .

Works electrothermal heater with ozonation and air recirculation as follows. Warm and moist air from the room is taken through the suction port of the heat exchanger 2 using an exhaust fan 1, passes through a filter 11, where it is cleaned of mechanical impurities and cooled and dried during heat exchange through the open damper 15 and the exhaust air duct 16 is removed to the street. External air is taken in through the opening of the supply air duct 13 using the supply fan 3, passes through the filter 12 and is supplied to the heat exchanger 2 and heated during the heat exchange through the air supply pipe 5 enters the electric heater 4, which, if necessary, is additionally heated. After it, the supply air is supplied to the air distributor 6, where after mixing with ozone coming from the corona discharge ozonizer 10 through fittings 7 and tee 8 via pipeline 9, it is fed to the locations of the animals.

Ozone (O ₃ ) is superior to other substances in the oxidizing effect, and this fact highlights it as a highly effective means of disinfection and air purification.

With a significant decrease in the temperature of the outdoor air, the shutter 15 opens and the exhausted warm room air, cleaned of mechanical impurities by the filter 11 and drained in the heat exchanger 2, is fed for partial recirculation. Once in the mixing chamber of the recirculation channel 14, it is treated with ozone coming from the ozonizer 10 through the pipe 9. In the mixing chamber of the recirculation channel 14, it is decontaminated. Mixing with the external supply air and additionally cleaning through the filter 12, it enters the heat exchanger 2, is heated by heat exchange, passes through an electric heater 4, an air distributor 6, and is fed to the locations of the animals.
