| Experimental Investigation of Ambient Temperature Effects on Domestic Refrigerator Performance and Running Ratio Abstract The domestic refrigerator is one of the most widely used household appliances, and improving its performance can significantly contribute to energy savings and environmental sustainability. Maintaining low and uniform temperatures is essential to prevent food spoilage and inhibit microbial growth. This study experimentally investigates the impact of varying ambient temperatures (15°C, 30°C, and 43°C) on refrigerator performance and running ratio. Three refrigerator samples were tested in a controlled laboratory setting to evaluate their efficiency under different thermal conditions. The results provide insights into how external temperature fluctuations affect operational performance, offering a potential increase in running ratio by 16% when testing the samples in 30 °C compared with testing in 15 °C to matin the performance, slightly change in running ratio for the tested samples around 2% in 43 °C compared with its result in 30 °C. | ||
