THERMAL CURTAINS USING IN THE MICROCLIMATE SYSTEMS FOR LIVESTOCK FARMS
The article considers the possibility of using air thermal curtains in microclimate systems for livestock facilities. In microclimate systems to maintain a given temperature and humidity conditions in the room, a significant amount of thermal energy is spent on heating the cold air penetrating through the open gate. This is due to some technological operations. The use of thermal curtains has the purpose of limiting the amount of cold air entering through the open gate and heating it. The designs of thermal curtains at the place of intake and air temperature are considered. The main attention is paid to thermal curtains with lateral air supply through vertical slits on both sides of the opening. Their design features are considered and recommendations on their execution are offered. The method of calculation of air curtains for open openings in the outer walls of livestock buildings is proposed. The technique allows you to perform the calculation and determine the necessary thermal and structural parameters. Preliminary analytical calculations have shown that the use of air-thermal curtains reduces the consumption of thermal energy to maintain the required microclimate by 15-20%.
