Abstract [en]

Nowadays, many electrical appliances are used daily. The refrigerator is one of them.

Consequently, by affecting the energy used by the refrigerator, a huge amount of energy,

greenhouse gases (GHG) emissions and money can be saved. It is what this thesis tries to do

by applying a concept: using the cold from outside. Indeed, this report exposes the process to

answer the following question:

How much energy, GHG emissions and money can be saved by using the cold from

outside on the refrigerating appliances?

To do so, measurements have been done on a refrigerator placed in a climate chamber. The

experiment procedure is inspired by the Swedish standard of energy consumption testing in

order to have the most relevant results as possible. The results of the measures were then used

to create a mathematical modelling. And finally, by applying the modelling at different

climate of the world represented by chosen cities, calculations were made to estimate the

energy, GHG emissions and money savings which can be done thanks to this concept.
