Project study
Cabin climate control for a mobile work machine
A transient thermal scope linked heating and cooling capacity, airflow distribution, surface temperatures and external loads for comparison of compact HVAC concepts.
CFD simulation · Thermal analysisMobile-machine cabin climate
Engineering question
Supply system and airflow had to be assessed for cold and warm states without separating comfort, transient response and component thermal effects.
Boundary conditions
- Steady and transient heating or cooling states
- Convective, conductive and radiative heat transfer
Assessment focus
- Heating and cooling response under cold and warm ambient conditions
- Effect of air distribution and surface temperatures on thermal comfort
Study objective
The objective was to compare HVAC concepts and air-distribution layouts for cabin thermal design.
