Abstract
The performance of heating systems in passenger cars is a crucial factor affecting thermal comfort, safety, and energy efficiency, particularly in cold climates. Despite advances in automotive HVAC (Heating, Ventilation, and Air Conditioning) systems, comprehensive testing methods for heating functionality remain a challenge due to vehicle design diversity, user expectations, and environmental factors. This study investigates and evaluates various testing methods for heating systems in light vehicles based on international standards and practical approaches. Using experimental and simulation techniques, several heating configurations are analyzed for heat-up time, temperature distribution, energy consumption, and occupant comfort. Results suggest that multi-zone thermal mapping and standardized driving cycles provide the most reliable assessment framework. Furthermore, the study proposes improvements to current testing protocols to ensure better reproducibility and alignment with real-world conditions.
