Evaluation and Analysis of an Agro-Based Nano Refrigerant to Improve the Performance of a Domestic Refrigeration System

The use of nanoparticles along with the conventional refrigerant in a vapor compression cycle is relatively new idea, where nano-refrigerants are found to have improved thermo-physical properties over refrigerants. Nano-refrigerant combination improve performance refrigeration process. In this study, developed nanofluid from agricultural source (rice husk) was applied domestic refrigerator and its investigated. pre-developed which prepared using synthesis, centrifugation calcinations processes administered compressor at concentrations 0.2wt%, 0.3wt%, 0.5wt% 0.6wt% form mix R600a used (as control) allowed run for 4 hours. Performance evaluation measured parameters such as pull down time, discharge temperature coefficient (COP). Results show an increase COP by 31, 23 35% compared control sample 0.3wt% respectively. showed best time temperatures -6.1 -3.1℃ 240 minutes respectively reduced 7-16% respect sample. Hence, rice husk based nanofliud resulted enhanced refrigerator.
