Due to the increasing effects of global warming, it is necessary to improve vehicle air conditioning systems. Among the various methods for enhancing cooling performance in the automotive industry, selecting the right approach—while considering time and cost priorities—is crucial. For this purpose, the use of an internal heat exchanger in the R134 refrigerant circuit, achieved through a modified manufacturing method, has gained significant attention in the automotive sector. This article presents the results of applying a new manufacturing method to an air conditioning pipe equipped with an internal heat exchanger in the Tara vehicle. The findings demonstrate that using an internal heat exchanger reduces the evaporator surface temperature, leading to a decrease in the average cabin and vent temperatures by approximately 7°C and 12°C, respectively, under highway driving conditions. In the traffic driving cycle, the results show that the internal heat exchanger reduces the average cabin temperature by about 5°C under optimal conditions.
