Low-carbon approach with the low-temperature air distribution in air-conditioning applications

Today, air management in air-conditioning processes is characterized by low displacement preferences independent of energy loads. Particularly in low-carbon approaches where thermal control management is gaining value, energy sustainability is being shaped together with effective heat management. In the thermal control approaches of air-conditioning systems, low-temperature air distribution together with heat mobility can be seen as an approach for an energy-efficient solution. In this study, first of all, the technical characteristics of the low-temperature air distribution system and its effects on the air-conditioning systems were examined, and the efficiency effects of the distribution system on the air-conditioning potential were evaluated. In the study, the energy efficiency effect of refrigerant preferences was especially assessed. It has been observed that the low-temperature system preference in air handling units varies depending on the refrigerant preference. In fact, it represents an increase in efficiency of 61.95% for R410a fluid and 61.84% for R134a. In addition, the environmental performance index based on entropy production also indicates an advantage of 22.24% for R410A and 25.26% for R134a. At the end of the study, thermodynamic and environmental assessments were made depending on the performance effect of the system.
