Perversum multicell heater, this second thermocouple through the temperature unit is connected to the second two-piece heater.

A disadvantage of the known device is the absence of the scheme, excluding the emissions of combustion products in the livestock or poultry facilities for use of the kit IR burners.

The direct output of combustion products from the IR burners in agricultural premises, on the one hand, allows them warmth, on the other hand, it will considerably relative to norms RSTP-4-93, be saturation of the CO2and other gases from the combustion products, which will require more active ventilation, additional energy consumption, increase the local velocity near the floor. This creates unfavorable conditions for the development of animals and birds, especially in the first period (the first week). The direct output of the combustion products in the agricultural space makes use of the level control of heating at different periods of development and growth of animals and birds in accordance with the rules RSTP 4-93. In the process of development of animals, birds living organism is allocated a different amount of heat, CO2and H2O, it requires a different level ventilation/x space, that is chami combustion, they are not used.

For "light" infrared burner with a temperature of the surface radiation over 800oWith a capacity of 3.2 kW, thermal power 2,33 kW (radiation is 1.95 kW, convection 0,388 kW), heat coming from the burner products of combustion 0,827 kW, consumption 3,24 m3/h, which includes the release of CO2the number of 0.37 m3/'clock In the table. 1 presents data on the production of CO2and H2About in the house on 20 thousand birds.

In table. 2 presents the necessary amount of air flow for the organization of heating in the house on 20 thousand birds and the amount of air for removal of CO2(thinning to normal) when I remove it from the house and from the burners. As can be seen from the table. 2, when considering the allocation of CO2from the birds of the air flow in the poultry area must be increased in the 1.06-2 times, and when considering the allocation of CO2from birds and burners should be increased from 8.5 to 1.5 times in accordance with the rules RSTP 4-93. The emission of combustion products from the IR burners in agricultural premises will significantly reduce the load on ventilation, significantly reduce energy consumption and improve the ecology of the habitat of the bird.

The above disadvantages are eliminated using the proposed the proposed system is achieved by the creation of comfortable conditions of heating while saving gas.
