OPTIMAL ARRANGEMENT OF THE LONGITUDINAL LINES OF THE LAMPS AT THE FLOOR POULTRY KEEPING

Abstract

A standard-width poultry house with outdoor poultry keeping is considered, for which longitudinal lines of LED lamps are used for lighting. The need to increase the productivity of poultry leads to the urgent problem of creating the most uniform energy-saving lighting of the working area of the facility. When solving the problem, the problem arises of estimating the optimal distance between the lines of lamps of the Lop. Its solution is possible using the optimality criterion. Difficulties in accounting for reflected light are the reason for searching for a criterion independent of the reflected component. (Research purpose) The research purpose is evaluating the optimal distance between the longitudinal lines of lamps for poultry houses of standard width based on a criterion independent of the reflected component of illumination. (Materials and methods) The shortcomings of the recommendations obtained on the basis of the utilization factor method were identified. It was proposed to take into account the width of the poultry house to overcome the shortcomings and evaluate the Lop by the point method. A model of diffuse light reflection was applied. The optimality criterion was substantiated and an algorithm for the computer evaluation of Lop was developed. We used the developed algorithm for poultry houses of standard width. (Results and discussion) Poultry houses with a width b, a multiple of 6 meters, were studied with a constant length of each poultry house a1 = 78 meters for the height of the suspension of lamps H1 = 3.0 meters, H2 = 3.5 meters and H3 = 4.0 meters. Presented the results of the assessment of the protected areas in the form of a table. It was revealed that the dependence of Lop(b) is quadratic. (Conclusions) It has been established that the assessment of Lop can be performed in a model of diffuse reflection of light based on a criterion independent of the reflected component of illumination. It was noted that with the arrangement of the lighting lines, according to the table, the risk of unauthorized demolition of eggs by poultry decreases, which contributes to improving the quality of the eggs obtained and increasing the productivity of poultry. It was stated that the results of the Lop assessment can be recommended to specialists of poultry farms to adjust the existing lighting system or before purchasing it to plan an energy-efficient arrangement of lamps.
