The invention relates to the field of agriculture, technology rearing and maintenance of agricultural animals and poultry. Primarily the invention relates to a local heating rabbits, piglets, lambs, chickens, geese and turkeys the brooders.

Known convective-radiative electropower for chickens in the form of a metallic umbrella defined in its upper part by a tubular electric heaters (see brochure "Brooder BP-1A". M: (Author : N.Yu. Ed. # 122/3086. 1986. 1 C.). High reliability and safety.

The disadvantages of this widespread brooder are technological inconvenience when using it because of its great mass and size parameters and high energy consumption due to the large air brooder.

Known brooder-house for piglets in contact with the floor of the pigsty dome in the shape of a half cut crosswise and vertically standing on a circular base of the paraboloid of revolution of transparent plastic with established near its top, infrared and ultraviolet lamps (see A.S. USSR №1340679. And 01 To 29/00. House for piglets. / Ackleson, Rentalasian, EAL // BI. 1987. No. 36. Cm. also: Zasypala CENTURIES, Lantsov A.K., Torosyan R.N. The brooder for piglets-when snow PC heat and UV radiation / Technology in agriculture. 1989. No. 2. P.14-15). For entry and exit of piglets has one hole with a transparent shutters, which is located on the floor level of the room. This solution has a clear power advantage over the known brooder heaters type and even greater energy advantages over conventional infrared heaters with luciotraut valves through the use of heat from the heated emitter litter inside the dome, no drafts, and accordingly the absence of a large convective heat transfer of the heating zones, and facilities management thermal regime.

The disadvantages are the loss of radiant energy through transparent to radiation wall design brooder-house and the loss of energy from the hot air by conduction through the plastic fencing with a relatively high thermal conductivity.

These disadvantages of the known and similar technical solutions of brooders for farm animals due to either high weight and performance of their designs, either the low electric security or loss of part of the radiant heat flux through the transparent wall, or loss of thermal energy by convection of the heated zone of the heated air through drafts or conduction of thermal energy across the insufficient heat-insulating wall of the brooder.

The objective of the invention is to reduce energy consumption brooder, reducing its mass and size parameters and the corresponding increase of the efficiency of service brooder. Another object of the invention is to expand the functionality of low brooder with a wide range of changes in temperature of the internal air of the facility.

As a result of use of the invention reduces the required power of the local heater and is saving fluid from the energy source almost any kind due to the concentration of the radiant component of heat flow from the emitter to the animals only within the zone of heating. This technical result is achieved by using insulating and luteotrophic blinds. By reflecting radiant heat energy from facing the area of the heated mirror for heat radiation surface vertically installed on the perimeter of the brooder blinds is achieved by the additional heating of the floor or litter in the zone of heating. So there is an additional temperature increase in the volume of heated local habitat, more uniform radiant heating surface of the animal from many directions and the corresponding impact on plooman animal's previous level of infrared radiation. Easier to achieve to satisfy the first condition of thermal comfort, which is required for the cultivation of animal its level of heat transfer. Therefore facilitated by the local thermal regime of the heater, resulting in its previous level of energy consumption is significantly reduced. Vertical incisions blinds allow animals without special effort to get out of the brooder, deflecting or bending the portion of the cut sections of the curtain under the influence of his body, and also to enter the zone heating the brooder, acting on the cut sections of the blind and bending them into heating zones. Without affecting the animal's body shutters occupy a vertical position and reflect infrared heat inside the heating zones, while preventing convective loss of heat the brooder through the movement of air between the area of heating the brooder and the rest of the space. Thus, the use of the invention is achieved by the use of insulating shutters with put on them internally to the construction of brooder side Lokotrack coating. Blinds have vertical slits, resulting ensure free entry of animals under the brooder and their exit from under him. When this conductive heat transfer brooder with a production location reduced the and through the use of heat insulating material of the blinds, convective - through cuts blinds with the lowest clearance or no clearance, radiant - through infrared reflecting material inner side of the curtain.

Another result of the use of the invention is to increase the productivity and livability. This technical result is also provided blinds to reflect heat radiation facing the inside of the heating zones of its surface. Multiple reflection of heat rays from various directions cause a uniform radiant heating almost the entire surface of the animal from many directions, which reduces the uneven distribution of the surface temperature of the animal, which can be a source of animal diseases. Thus, is the second condition of thermal comfort, directed in this technical solution to increase the uniformity of infrared heating surface of a biological object.

The result of the use of the invention are also advanced features for use in chilled standards in excess livestock building, because its thermal regime of weakly depends on thermal properties of the environment.

This technical result is achieved by the fact that the proposed brooder for heating selskohozyays the public animals, representing the rigid structure of the heat insulating element installed under the insulating element by the heat sources, and on the perimeter of the brooder posted by vertical insulating blinds, covered with a facing zone heating them Lokotrack in the range of the emitter material, the height of which is sufficient to touch the lower edge of the floor heating zones and installed by fastening to the structure of the heat insulating element, and curtain-side with their lower edges are vertical sections.

Figure 1 shows a diagram of a rectangular versions brooder, a cut in the vertical plane. Figure 2 shows the principle of the brooder with plots field thermal radiation and air temperature in the heated volume. Figure 3 shows schematically a graphical illustration of the energy benefits brooder for infrared oblojennosti in a horizontal plane on the surface of the heated floor area of animals or poultry in comparison with the trivial infrared heater, and an infrared brooder-house with a transparent dome.

The brooder for heating farm animals and poultry is a rigid structure of the heat insulating element 1 installed under the insulating uh what Eminem 1 sources of heat 2, moreover, the perimeter of the 3 designs brooder posted by vertical insulating blinds 4 covered with a facing zone heating them Lokotrack in the range of the emitter material 5, the height of which is sufficient to touch the lower edge of the floor heating zones and installed by fasteners 6 on the structure of the heat insulating element 1, and the shutter 4 from its lower edge are vertical sections 7.

The brooder works as follows. The radiant heat flux is reflected from lucotrudeau material blinds and remains almost completely in the zone heating (see figa), raising animals feel the room temperature under the brooder. At the same time increased the level of the floor under the brooder heat radiation (see figb) additionally increases the temperature of the litter under the brooder, which leads to additional heating of the air in the zone of heating. Regarding the litter curtains of heat insulating material dramatically reduce useless air from under the brooder and contribute to the further increase in air temperature under the brooder (see figb) and, accordingly, feel the temperature in the zone of local heating. At the height of the brooder is determined mainly by the size of the heated animals and taking into account required for breathing animals ventilation can be minim the school compared with other local heaters, because in the brooder can be applied to low-temperature heat sources. Therefore, the volume of heated space under the brooder is relatively small. The result is to reduce the power sources radial convective heat recovery required on cultivation of agricultural animals thermal conditions under the brooder, i.e. to reduce its energy consumption.

This is the principle of saving this brooder. Figure 3 shows the same radiation power irradiators in the local heaters these different types: high irradiance within the zone heating the brooder Emirrorcompared to the brooder-house with transparent to radiation and thermally conductive material of the dome with lower irradiance Ebrooder-house,even greater energy savings compared to the trivial infrared irradiator animals with even less irradiance EIR irradiatorwhich distributes its radiant energy far beyond the surface area of the production area, heating, without delivering technological heating mode outside and having no technical means of thermal protection from the cooling influence on animals and on thermal regime in the zone of the heated moving air of the facility with ponie is authorized by temperature. Estimates for different conditions of heat exchange confirm energy savings the brooder for 5...10% compared to the most energy-efficient still the brooder-house and not less than 15...20% compared to conventional infrared irradiator with a reflective fixture.

Sufficient for breathing animals under the brooder ventilation is achieved and even facilitated by the inventive vertical sections of blinds, allowing for the same animal exercise is widely known, for example, in pigs, phenomenon: the pigs are under local heater, sticking out only their "noses".

Issues of application of the brooder in pollution lucotrudeau coverings blinds and mechanical effects on the animal completely solved by the use of modern self-cleaning under conditions of heating and mechanically strong enough luteotrophic insulating coatings, such as StekloSouz, penofolom and similar.

Thus, the brooder has in comparison with the known local heaters mass, energy and technological advantages, with advanced features for use in chilled standards in excess livestock building, because its thermal mode is only weakly dependent on thermal properties of the action.

The brooder for heating farm animals, representing the rigid structure of the heat insulating element installed under the insulating element sources of heat, characterized in that on the perimeter of the brooder posted by vertical insulating blinds, covered with a facing zone heating them Lokotrack in the range of the emitter material, the height of which is sufficient to touch the lower edge of the floor heating zones and they are installed by attaching them to the structure of the heat insulating element, and curtain-side with their lower edges are vertical sections.
