Abstract


Automotive air conditioning (AC) systems, traditionally powered by the engine, contribute to reduced fuel efficiency and environmental challenges. However, the heat released by the AC condenser has the potential for energy reuse. This study aims to design and evaluate an integrated thermal management system that combines the functions of a water heater and an AC. A lab-scale system is developed to investigate the thermodynamic behavior of the refrigerant and assess the system performance at various cooling water flow rates. The results show an increase in the Energy Efficiency Ratio (EER) with this integration, which offers new applications, such as intercity buses by providing warm water for on-board toilets. This innovation not only improves passenger comfort but also improves energy efficiency and sustainability in transportation systems. The proposed integration is an example of a practical approach to utilize waste heat and address energy and environmental issues in modern vehicles.
