An Analytical Study of the Efficiency of the Natural General Ventilation of Cattle Building
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 21, Issue
Abstract
Operating costs for the work of general ventilation systems is about 30 % in the energy balance of premises for keeping cattle. The possibility of increasing the efficiency of general ventilation of the premises for keeping cattle due to the transition from mechanical to natural ventilation in certain period of the year is analysed in the article. The analysis is based on a compatible solution of equations of heat and air balance in cowshed and analytical productivity of changes of natural ventilation when the outdoor temperature of air is different in each season. The combination of mechanical and natural ventilation significantly reduces the annual consumption of electric energy by the engines of ventilation units of general forced ventilation. Outside the heating period, the operation of natural ventilation must be duplicated by forced ventilation systems
