Abstract
Relevance. It is known that the productive qualities of animals depend on the genetic component and animal housing conditions. Due to the fact that the microclimate of the room should be perceived as a complex dynamic system, it is necessary to determine a number of factors that have the greatest influence on its relationship with living organisms. In order to create favorable conditions in the premises for keeping cattle, it is necessary to comply with the regulated values from normative documents. The biggest problem at the moment in microclimate regulation is the detrimental effect of heat stress. As a rule, it is caused by uncontrolled temperature increase in the cattle housing. To date, heat stress is combated in several ways: the use of specialized equipment, pharmacological, prevention of harmful effects, genetic. At the same time used methods to reduce the impact of heat stress is still insufficient, in view of which nowadays research is conducted to create new systems.
The purpose of the study was to conduct simulation modeling to verify the values obtained from theoretical studies. Computer-aided design and data processing programs such as Compass-3D and Microsoft Office were used.
Results. The results of the study allow us to establish that the velocity of the outgoing air flow at the moment of exit from the duct is 1.615 m/s, and the velocity of the air flow when approaching the cattle decreases and reaches 0.450 m/s. These values are lower than the theoretical one by 15% and 10% respectively. The relationship between the results of simulation modeling and theoretical values is direct and has a strong closeness of relationship, convergence is equal to 0.86.
