Превышение допустимых концентраций газов приводит к заболеваниям животных, падению продуктивности и падежу молодняка КРС, поэтому целесообразно прогнозировать концентрацию газового состава в животноводческом помещении. С целью определения и распределения вредных газов (аммиак, сероводород, углекислый газ) в животноводческом помещении осуществлено 3D-моделирование фрагмента фермы в программном комплексе SolidWorks 2020. Созданы параметрические модели движения газов в различных условиях и определены оптимальные точки замеров концентрации газов в животноводческом помещении. Произведенное моделирование позволило определить направление воздушных потоков, обнаружить скопления и облака газов. Максимальная концентрация углекислого газа выявлена на уровне 0,9 м (скорость воздуха – 0 м/с) и на уровне 1,3 м (скорость – 0,75 м/с). Наибольшая концентрация сероводорода отмечена в области, граничащей с коньковым пространством (скорость воздуха – 0 м/с), и на уровне 2,25 м (скорость – 2 м/с). Наибольшая концентрация аммиака наблюдается под крышей и в области под коньком (скорость воздуха – 2 м/с). Рекомендовано устанавливать датчики сероводорода и аммиака под коньком, датчики углекислого газа, сероводорода и аммиака – в стойле, датчики углекислого газа и сероводорода – у кормового стола. Измерение концентрации необходимо производить на высоте 500, 1500 и 3000 мм. При увеличении концентрации выделяемого газа и прочих равных условиях увеличивается концентрация газа в облаке, но структура облака изменяется незначительно. Датчики опроса параметров необходимо устанавливать в закрытых продуваемых боксах, как в погодных метеостанциях.</p></abstract><trans-abstract xml:lang="en"><p>Indoor climate parameters influence the productivity of animals and their physiological condition. Exceeding permissible concentrations of gases leads to animal diseases, loss of productivity, and the mortality of young cattle. Therefore, it is reasonable to predict the concentration of gas composition in the livestock houses. To determine and distribute harmful gases (ammonia, hydrogen sulphide, and carbon dioxide) in the livestock house, the authors performed the 3D modeling of a fragment of the farm in the SolidWorks 2020 software package. Parametric models of gas movement under different conditions were created and optimal measurement points of gas concentration in the livestock house were determined. The simulations made it possible to determine the direction of air flows and detect accumulations and clouds of gases. The maximum concentration of carbon dioxide was detected at 0.9m (an air speed of 0 m/sec) and at 1.3m (a speed of 0.75 m/sec). The highest concentration of hydrogen sulphide was found in the area bordering the ridge space (an air speed of 0 m/s) and at the level of 2.25 m (a speed of 2 m/s). The highest concentration of ammonia was observed under the roof and in the area under the ridge (an air speed of 2 m/s). It is recommended to install hydrogen sulphide and ammonia sensors under the ridge, while carbon dioxide, hydrogen sulphide and ammonia sensors – in the stall, carbon dioxide and hydrogen sulphide sensors – near the feed table. Concentrations should be measured at heights of 500, 1500, and 3000 mm. When the concentration of emitted gas increases and other conditions are equal, the concentration of gas in the cloud increases, but the structure of the cloud changes insignificantly. Parameter interrogation sensors should be installed in enclosed ventilated boxes in the same manner as in weather stations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микроклимат</kwd><kwd>КРС</kwd><kwd>аммиак</kwd><kwd>углекислый газ</kwd><kwd>сероводород</kwd><kwd>параметрическая модель</kwd><kwd>моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>indoor climate</kwd><kwd>cattle</kwd><kwd>ammonia</kwd><kwd>carbon dioxide</kwd><kwd>hydrogen sulfide</kwd><kwd>parametric model</kwd><kwd>modeling</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Довлатов И.М., Юферев Л.Ю.
