Abstract

This research aims to investigate the thermodynamic performance, including temperature differential properties and energy efficiency ratio (EER) of the air conditioning cooling system. A 2.5 kW split inverter air conditioning with R-410A was applied in this research for investigation and integrated with a microcontroller ATmega 2560 for data acquisition. The investigation was carried out between temperature setpoint of 16°C and 20°C. An online psychrometric chart calculator was employed in this research to facilitate the calculation of thermodynamic properties. The results showed that the average temperature differential across all the temperature setpoint was found to be 11°C to 12.89°C. This result indicated an ability to exceed the minimum tolerance allowed for evaporator temperature differential standards. Moreover, the highest result of the EER of the air conditioning system was 13.87 at a temperature setpoint of 20°C. The research revealed that all temperature setpoint ranging from 16°C to 20°C yielded EER values within the range of 8 to 15, which is widely recognized as the efficient operational range for residential air conditioning applications. In addition, this air conditioning system has better energy efficiency and cost savings over the lifetime of the cooling system. The integration of microcontroller technology in this research facilitated the real-time recording of each investigation parameter. This approach enhanced the efficiency, complexity, and reliability of the experimental investigation of the air conditioning system.
