CALCULATION OF HEAT LOSS THROUGH CHAMBER WALLS OF MULTIFUNCTIONAL HELIOTECHNICAL DEVICE

Abstract

<p>The heat requirement of an egg incubator working with solar energy is studied in the<br>article. In the determination, the following were made: there is a steady-state condition, onedimensional<br>heat flow prevails, the incubator materials have a constant thermal conductivity, and<br>the incubator is a closed system at a constant temperature. When it comes to incubator design, the<br>heat required and delivery are important considerations. The temperature and relative humidity in<br>the incubator depend on the degree of heat and ventilation supplied. Adequate heat supply and<br>ventilation increase air circulation and heat transfer.It is provided with continuous heat and electricity, and the heating, ventilation and cooling<br>system of the hatchery can save up to 1.5-2.0 times the electricity compared to incubators with lamps<br>or TENs that work on traditional full electric energy, useful work coefficient It was found to be 95%.<br>As a result of the introduction of the device, the cost of the product was reduced by 30-40% due to<br>alternative energy sources. In addition, the drying of medicinal plants allows temporary storage of<br>perishable agricultural products.<br>Based on the analysis of scientific and technical materials and scientific research, the scheme<br>and heat losses through the walls of the multifunctional heliotechnical device were substantiated.<br>It was found that the proposed multi-functional solar powered heliotechnical device has the<br>ability to effectively incubate in the incubation mode. The results of the indoor environment of the<br>installed incubator were found to be close to the results required by natural egg incubation. The use<br>of the system in the poultry industry eliminates the problem of electricity supply.</p>
