MAINTENANCE OF TEMPERATURE AND HUMIDITY CONDITIONS IN ANIMAL BUILDINGS IN THE MOUNTAIN ZONE OF AZERBAIJAN

Abstract

Material is given from a research into the resource-saving options of ventilation and heating systems applied for winter, summer and transient conditions in poultry and stock buildings. The research was carried out under conditions of the mountain zone of Azerbaijan, the analytical studies at the Azerbaijan State Agrarian University. Experimental studies of the temperature field in the animal zone have shown that when atmospheric air with the temperature of -5°C in winter enters the building and mixes with warm indoor air, the temperature of air mixture at the outlet of diffuser reaches 6 °C, and 13 °C at the distance of 3 m on the axis of diffuser. In the animal area, the temperature of indoor air ranged from 11 to 12°C that meets the requirements of zootechnic standards for cattle. Relative air humidity in the animal area, when supplied unheated indoor air with the temperature of -5°C in winter, did not exceed the permissible normal values, and made up 80% on the average. After operating the decentralized units, relative air humidity was stabilized in 2 hours at the level of 74%. Based on theoretical and experimental studies conducted as well as on model projects of poultry and stock premises, design solutions of ventilation systems have been developed that allow using the warmth of indoor air in combination with the heater.
