Elements of microclimate normalization system in the cabin of TORUM grain mandy combine

Abstract

Abstract The article conducted a study of the working conditions of the combine operator, as a result of which it was revealed that the occupational hazards of an employee are unfavorable microclimate parameters. Based on the analysis of the thermal state of the combine cab during the summer and winter operation, a microclimate normalization system has been proposed, for which the main functional characteristics (cooling and heating capacity) have been determined. According to the results of the calculation, the relationship between these characteristics and the working speed of the combine is established. So, with the increase in the speed of the combine up to 20 km/h, the cooling capacity of the climate system increases by 36%, and the heat output – by 22%. The surface areas of the main elements of the microclimate normalization system (condenser and evaporator), providing the necessary performance, are also determined.
