Experimental & CFD analysis of Hybrid Air-Conditioning system using nanofluid via Heat & Mass Transfer Characteristics

Abstract

This research paper investigates the heat and mass transfer characteristics of hybrid air conditioning system with radiator as indirect evaporative cooler and chilled water spray using nanofluid. Both experimental and computational fluid dynamics (CFD) analyses were conducted to study the heat transfer coefficient and the effect of water spray on the temperature and humidity of the air. The experimental setup consisted of a duct radiator and chilled water a water spray system using nanofluid, while the CFD simulations were performed using Python’s CFD Analysis Toolkit which assisted in performance evaluation for different use cases. The results show that the Coefficient of performance (COP) of hybrid air-conditioning system increases with the water flow rate, nanofluid concentration and controls the temperature and humidity of the air with respect to the nanofluid chilled water spray levels. The CFD simulations provided a detailed understanding of the flow and temperature distribution inside the air duct, and the results were in good agreement with the experimental data samples. The findings of this study can be useful in designing and optimizing the performance of hybrid air-conditioning system with nanofluid chilled water spray systems for various applications, such as cooling electronic equipment or air conditioning systems.
