OPTIMIZING AUTOMOTIVE AIR-CONDITIONING PERFORMANCE WITH INNOVATIVE SPRAY-BASED COOLING

This study investigates the impact of cooling fluid mist as an auxiliary condenser cooling method on the performance of automotive air-conditioning systems. Experimental tests were carried out using two vehicles—a 2014 Toyota Camry and a 2012 Nissan Pathfinder—under varying ambient temperature conditions. The research focused on analyzing the effects of mist application on key performance indicators, including low-side and high-side pressures, compressor workload, and thermal efficiency. Results showed a marked improvement in condenser efficiency when the mist system was engaged, leading to lower system pressures and enhanced cooling performance. These improvements contribute to increased energy efficiency, reduced thermal load on the compressor, and potentially longer service life of the air-conditioning system. The study concludes that implementing cooling mist technology is particularly beneficial in high-temperature regions and offers a promising direction for the enhancement of automotive HVAC systems. It also recommends further research on system integration and trials with alternative refrigerants to expand the scope of application and sustainability of the technology.
