Abstract
The objective of this dissertation is to study and evaluate the energy performance of domestic
refrigerators. More specifically, the increase in efficiency of domestic refrigerators is
investigated, ultimately aiming to save on electricity consumption.
There is also a description of methods with which refrigerators may achieve higher
efficiencies with reference to existing studies and their results. After analysing the above,
there is an extensive description of the factors which influence the energy consumption of a
domestic refrigerator and the various ways that may be adopted by the consumers to save
energy are outlined. The reliability and the precision of temperature control units and other
devices is examined through laboratory testing, along with the question whether there is an
increase of electricity consumption by reducing the internal temperature.
Furthermore, the differences between the mechanical and electronic temperature control units
are observed and a study follows on the potential to reduce a refrigerator’s electricity
consumption using power factor correction.
Finally, there is a consideration about whether the increase and decrease of the amount of
refrigerant in the system as well as other modifications of the refrigeration cycle affect the
refrigerator’s performance.
