Abstract
The analysis of local infrared (IR) heaters of young animals with an assessment of their energy efficiency is carried out. Energy saving infra-red heater with regulated heat flow depending on position of animal, for calves, has been designed. The fittings and the reflector of the IR heater allow the use of various heating elements. Electrical circuit diagram of automatic control unit of energy-saving IR heater for prophylactorium period calves, in single penning breeding technology, has been described. The outlay of installation with electric heater has been described and an example of irradiance calculation has been presented. Mathematical expression for calculating irradiance from electric radiant heater, in particular point on the heated surface, has been defined by experiments. It was found that the proposed design and heater control scheme provide a reduction in energy consumption by up to 35% compared to traditional methods of maintaining the temperature in the area where the calves are located.
