Abstract
The aim of the study is to analyze and select a rational method for calculating heat suply from solar radiation for the correct determination of the thermal load on the climate system of the cabin of a mobile machine. The correct calculation of this component of the heat balance allows to correctly determine the power of the climate system of the cabin, which ensures optimal working conditions at the workplace of operators of mobile machines. To achieve the goal, the most common methods for calculating solar radiation were described and analyzed in detail, and the most accurate ones were recommended. The more laborious Bogoslovsky method (taking into account the time of the day) can be recommended for automated calculations in Excel, and the Hamburg method (taking into account the horizon sides) – for comparative evaluative engineering calculations. When carrying out “in-depth” model calculations and accounting for solar radiation, the ASHRAE method is explicitly suitable, which has two important advantages: it takes into account the solar factor in relation to a specific type of glazing and is adapted for automated calculations in ANSYS FLUENT.
