Abstract

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.
