Application of solar maps to select a rational shape of the shading device for the tractor cabin

Abstract

The article is devoted to the use of solar maps to determine the period of unwanted insolation and the amount of thermal radiation that penetrates into the tractor cabin throughout the entire working day. In addition, an optimal form of a sun-protection device has been proposed, which makes it possible to reduce the magnitude of the exposure dose of thermal radiation affecting the operator. Since solar radiation makes the main contribution to the heat balance of the cabins of mobile machines (tractors, combines, etc.), the results obtained can mainly be used in assessing the working conditions of operators and in calculating and choosing systems for normalizing the microclimate (ventilation and air conditioning).
