Investigation of the Use of Underground Cold in a Tunnel-type Ventilation System

The article analyzed the main factors affecting the productivity of birds, indicating the importance of poultry production, and also studied the widespread use of two storage systems in poultry farming. As a result of the conducted analyses, the task was set to study the optimal parameters and operating modes of the installation providing tunnel-type ventilation as a working hypothesis for warm climatic zones. The aim of the study was to increase the reliability of the cooling effect inside the building in tunnel-type ventilation installations. Based on the existing methodology, an experiment was conducted and positive results were obtained. The obtained methods have shown that it is not possible to provide the treated moisture inside the building with normal ventilation. Cooling systems ensure normal humidity. But here the use of an underground cooling channel has a wider range of redundancy. In the experimental version, egg production increased by an average of 1.26%, and the weight of eggs increased by 1.5%, and the losses of birds for 5 months of the warm period were 21 heads less.
