Study of the regularities of the influence of air heat curtains on the energy balance of livestock premises

Abstract

The use of air heat curtains allows you to limit the amount of cold air incoming the room through open gates or doors, as well as to heat it up. The article considers the influence of air heat curtains on the energy balance of livestock premises. The calculation method is presented and the main aerodynamic characteristics of an air curtain installed in a calf house for 50 animals are substantiated. The main heat and power and structural parameters of the air curtain have been determined. On the basis of the heat balance of the calf barn, its modes of operation are substantiated. It has been established that the power consumption for the fan drive during the operation of the air curtain is significantly less than the cost of thermal energy to compensate for the air temperature in the room from the inflow of cold air. The technical and economic calculation showed the effectiveness of the use of air heat curtains in microclimate systems for various livestock facilities of agricultural production.
