Impact of solar radiation on the climate of a passenger car

Abstract

The volume of passenger traffic is constantly growing. Accordingly, the requirements for passenger transportation conditions are increasing - it is necessary to ensure improved comfort. Since the travel routes of passenger cars follow different climatic zones, comfort dictates the need to maintain a constant temperature in the car - 22-26˚C in summer, 20-24˚C in winter. The temperature regime in the car also depends on the materials used in car construction, namely: the heat transfer coefficient, the thermal properties of the car materials. In addition, window openings of passenger cars also participate in heat transfer processes, which also affects the climatic conditions in the car. The article presents the results in the form of calculations and graphs of temperature dependences of the influence of solar radiation on climate (temperature conditions) in a passenger car.
