УСОВЕРШЕНСТВОВАНИЕ СИСТЕМЫ ВОДОИСПАРИТЕЛЬНОГО ОХЛАЖДЕНИЯ КОРОВНИКОВ

Abstract

The research was carried out in order to solve the problem of elevated air temperatures in livestock buildings during the hot season. The maximum intensity of moisture evaporation from the surface of the sample, blown by air flows of different speeds and directions, is achieved with the alternating action of the flow from opposite directions. As a means of creating a comfortable microclimate that can provide a change in the direction of air flows in barns, it is most advisable to consider the joint use of accelerating axial fans installed along the entire room and fine spraying of water, which gives a significant (up to 11°C) cooling effect. The developed devices for inducing air exchange and air conditioning for livestock farms have design features that allow you to change the direction of the air flow injected by the fans by 180 °, which provides a non-stationary ventilation mode that prevents the formation of stagnant zones in the air volume of the room, increases the assimilation capacity of the air and improves its quality indicators. The direction of the air flow is set using a reversible electromagnetic starter, or a system of cables and counterweights. At the same time, the cooling of the air flow using fine water spray is carried out taking into account the direction of its movement and is regulated by the control unit. Changing the direction of the air flow to the opposite also provides an increase in the surface area of the bodies of animals in contact with the flow, and, as a consequence, an increase in the cooling effect. The use of the proposed developments will make the microclimate in the summer more comfortable for animals, which will positively affect their productivity.
