Abstract
With the onset of cold weather, heat transfer through the walls and especially the roofs of bird rooms, unlike in the summer period, increases significantly, which leads to a sharp decrease in warm indoor air. Therefore, in order to maintain the regulatory conditions of the ventilation system, it is reduced to a transitional mode, and then to a minimum ventilation mode. Low ventilation repeatability limits inside the building determine the minimum volume of air supplied by the ventilation system. The economic and production efficiency of poultry farming is related to the premises and climatic conditions, which can seriously affect the well-being of broilers. Heat stress contributes to behavioral, physiological and biochemical changes in broilers, which leads to economic losses.
 The purpose of this study is to influence the annual efficiency of the poultry house ventilation system, mainly in summer, in order to evaluate the efficiency during the reconstruction of the cooling system, that is, to improve the ventilation system of the room, as well as to give an economic assessment of waste disposal technology.
 Energy– and resource-saving, environmentally friendly technologies and technological tools, plastic-type recuperators, a bird droppings removal system, as well as lighting and irrigation processes were taken as the object of the study. In conducting our research, let’s use classical and special methods, including a decomposition method for analyzing the functional use of recycling technology, a logical and linguistic method for assessing the safety of nitrogen during disposal, microclimate technology, nutrition and storage.
 Based on the mathematical model, a computer research methodology was developed to improve the energy efficiency of the poultry house. Using a computer program, the number of LEDs (α=200, I0=20 cd) for an enclosure measuring 66×12 m is N=273 pieces, and the number of LEDs (α=200, I0=20 cd) for a building measuring 78×18 m is N=259 pieces. The design parameters of the illuminators are justified
