Abstract
The power consumption of domestic refrigerators shown by manufacturers is the result of
a set of internationally standardized measurements. The tests performed to determine it
are highly expensive due to the conditions that need to be established in laboratories.
Several investigations carried out in real working conditions are limited, and their main
problem has to do with obtaining the behavior of the variables under these conditions.
This document presents a proposal for a system of measurement and display of data from
a domestic refrigerator to analyze the behavior of energy consumption and thermodynamic
parameters (temperature, pressure, power and COP) in real operating conditions, case
study Neiva (Huila). The virtual instrumentation used to simulate the variables is supported
by an Arduino programming module and is integrated to the IoT ThingSpeak platform. With
this solution it was possible to establish different correlations between some of the variables
measured by means of MatLab.
To carry out this theoretical research, the historical logical method was used for the study
of the art, the method of induction deduction to determine the regularities of the hermetic
compressors, the analysis and synthesis to determine the key factors that influence the
phenomenon.
Finally, it was found that the power consumption of the domestic refrigerator in real
operating conditions for tropical climates (above 32°C ambient temperature) and voltage
variations [ 97 (V)-127 (V)] can be up to 30% higher than that provided by the manufacturer,
since these variables greatly affect the cooling power and COP variables, which are
extremely important in consumption.
