4problem that occurs while designing and operating poultry houses built as module structures. Literature review and problem statementGrowing poultry in an industrial environment is a challenging task. Young birds are especially sensitive to changes in the environment. In [1], there is research on the influence of an increased temperature and relative humidity on the bodies of broiler chickens. According to the findings, poultry consume less forage under the influence of high temperature and humidity. This adversely affects the growth of the poultry body weight. In [2], it is shown that in a clean environment the bird body assimilates nutrients and supplements better, so it is highly important to maintain temperature and humidity parameters in poultry sheds. To improve the efficiency of poultry houses, it is recommended to use local heating systems with infrared heaters [3][4][5]. This creates comfortable temperature conditions in the area of heating with the help of direct radiation. In [6], there is an estimation of different heating systems of a poultry house for broiler chickens. Specifically, the study examines a heating system with a direct heating 4  S. Shcherbovskykh, N.

Energy-efficient heating systems for poultry houses are infrared heating systems. With the correct location of infrared emitters heating occurs only in the zone where the poultry is located and the need to heat the entire poultry house disappears. In this way, it is possible to achieve the necessary zoo-hygienic parameters in the zone for breeding of young chicken, without increasing indoor temperature, and if it is possible, lowering it. On the basis of principle of sectional poultry breeding the modular breeding of chicken broilers is proposed. The heating system of the module is a panel infrared heater, intended for local heating of the growing zone. To ensure a constant inflow of fresh air and assimilation of harmfulness in the module provides an inflow and exhaust ventilation system. Modular poultry breeding allows to use modules as well as in industrial poultry farming, and within individual farms. As the industrial method of poultry breeding involves the accumulation of a large amount of poultry in one poultry house, there is a possibility of emergence and rapid spread of infectious diseases. Due to the local microclimate provided in the module for poultry breeding, it is possible to prevent this negative phenomenon. In addition, there is an opportunity to keep multi-year poultry categories in one poultry house and to provide a temperature regime as the growth of poultry. In this paper the study of temperature regime in the module at the change of thermal power of a heater was described. The results of experiment show that the greatest influence on the value of relative air temperature have thermal power of infrared heater and air velocity in module. At constant values of height of a heater installation and air velocity, and with increasing the heat capacity of heater twice, value of relative air temperature will increase by 3.8%. Due to the use of energy-efficient infrared heating system, it was possible to reduce annual expenses related to the purchasing feed by 11.7% and increase cost of final product of chicken-broiler by 12.8%. Based on technical and economic calculations, the use of modular poultry breeding with the infrared heating system was substantiated. This confirms the wide possibilities of implementation energy-efficient infrared heating systems.
