Experiments were conducted to compare the different effects of finned tube condensers coated and not coated with far infrared materials on the heat exchange and energy saving efficiencies of split-air conditioner in both the same outside air and indoor environments. Experiment results show that the use of commercial far infrared materials on finned tube condensers in split-air conditioner can increase the EER by 15.94-17.87%, power savings by 4.62-6.32%, the freezing capability by 9.8-10.58%, and outlet temperature reduction by 2.6%-4.1%. The far infrared materials used in this experiment are proven to be able to improve the in-service efficiency of heat exchangers. This means that the spray-applied installation method can significantly improve the viability of far infrared materials in future real world applications.
