Performance of a domestic refrigerator using nanoparticles-based polyolester oil lubricant

open access: yesJournal of Mechanical Engineering and Sciences, 2016
The performance of a domestic refrigerator with the addition of nanoparticles in the lubricant was experimentally investigated. Different sizes of nanoparticles of Al2O3 and TiO2 were added to the polyolester (POE) oil in two different volume ...

Performance Characteristics and Optimization of a Dual-Loop Cycle for a Domestic Refrigerator-Freezer [PDF]

open access: yes, 2012
A dual-loop cycle for a domestic refrigerator-freezer (RF) has a large energy saving potential because of lower compression ratio due to higher evaporating temperature in the fresh food compartment (R)-operation, and the individual optimization ...

Dynamic Performance Simulation of a Household Refrigerator with a Quasi-Steady Approach [PDF]

open access: yes, 2012
The paper presents a quasi-steady approach for modeling a household refrigerator. The model applies a novel methodology to perform the dynamic simulation. It uses a map of unit which contains high accuracy performance data of the refrigeration loop. This

Occurrence of Listeria and Enterobacteriaceae in Domestic Refrigerators

open access: yesJournal of Food Protection, 2008
Consumers' refrigeration practices have a significant impact on the safety and quality of foods. To determine the prevalence and the identity of microorganisms in domestic refrigerators, swab samples were taken from various locations in the refrigerators from 137 households in middle Tennessee.

Experimental Performance of R-1234yf as a Drop-in Replacement for R-134a in Domestic Refrigerators [PDF]

open access: yes, 2012
Concerns about anthropogenic climate change have generated an interest in low global warming potential (GWP) refrigerants and have spawned policies and regulations that encourage the transition to low GWP refrigerants. Recent research has largely focused
