Abstract [en]

This thesis concerns the use of solar control and electrochromic glazing in trucks. The purpose has been to study the decrease in solar energy transport into the cab and how to utilize the technology. The solar spectrum consists of both visible light and near-IR radiation, and solar control glazing transmits the majority of the visible light and reflects or absorbs most of the near-IR radiation. Electrochromic glazing has variable transmittance, which enables the driver to regulate the energy flow through the window. A decrease in energy transfer can reduce the use of air conditioning and give a lower peak temperature in the cab. This could generate a better fuel economy and a possibility to reduce the cost of the polymer material in the instrument panel.

Five different types of glass were tested in several experiments to determine the reduction in heat transfer. The experiments evaluate the performance of the glass in an environment with simulated solar radiation and forced convection, caused by the speed of the truck. The tests showed that during a sunny day with an irradiance of 1000 W/m2 there is a possibility to lower the cab temperature by 5 °C and the inflow of energy by nearly 90 W/m2.

A survey was carried out to get a subjective assessment of the use of solar control and electrochromic glazing, and other potential technical applications. The general consensus was that the decrease of solar radiation would create a better working environment for the drivers.
