text: The parameters required to calculate the energy efficiency of household refrigerating
appliances (i.e. refrigerators, freezers and their combinations) are determined
by standard measurements. According to regulations, these measurements are carried
out when the appliances are new. It is known from previous studies that various
technical aging mechanisms can increase electrical energy consumption by up to
36 % over a product lifespan of 18 years. In order to determine the time dependence
of the energy consumption of household refrigerating appliances, repeated measurements
are carried out in this work. Eleven new appliances are examined under standard
measurement conditions. After just two years of operation, an additional energy
consumption of up to 11 % is determined. Furthermore, 21 older appliances that
had previously been measured in new condition are tested again after up to 21
years of operation. For these older appliances, an average increase of energy
consumption of 28 % is found. For individual appliances, the maximum increase
is 36 %. An aging model is developed on the basis of these measurement results,
which may help to predict the aging-related increase of energy consumption of
household refrigerating appliances. This model shows an average increase in energy
consumption of 27 % for an appliance age of 16 years. Supplemental performance
tests of eight compressors do not show any significant aging effects related to
these devices after two years of operation. Furthermore, measurements of the thermal
conductivity of aged polyurethane foam test samples are carried out and an increase
of its thermal conductivity of 26 % over a period of about three years is determined.
