Development of microclimate normalization system elements in the cabin of torum grain harvester
Abstrak
The working conditions of the combine operator are investigated. It is revealed that the leading occupational hazards of the worker are microclimate adverse parameters. Based on the analysis of the harvester cabin thermal state during summer and winter operation, a system of microclimate normalization is proposed, for which the main functional characteristics — cold and heat capacity — are determined. According to the calculation results, the relationship between these characteristics and the operating speed of the combine is established. Computer modelling of heat and mass transfer in the conditions of active ventilation of the cabin allows us to get a more detailed picture of the formation of streams of air movement and temperature in the working area of the operator and to recommend measures of thermal protection.
