text: Die Energieaufnahme von Haushaltskältegeräten ist seit den 1990er Jahren erheblich
gesunken. Dieser Wert wird von den Herstellern im Neuzustand der Geräte unter
Normbedingungen bestimmt. Wie jedes technische System unterliegen jedoch auch
Haushaltskältegeräte einem Alterungsprozess, der zu einem Anstieg der Energieaufnahme
über die Zeit führt. Im Rahmen dieser Dissertation wurde auf der Grundlage von
100 Messungen der Energieaufnahme, die an 32 Geräten über einen Zeitraum von 21
Jahren durchgeführt wurden, ein Alterungsmodell entwickelt. Dieses Modell ist
das erste, das mit Hilfe von Daten der Energieaufnahme real gealterter Geräte
entwickelt wurde. Es beschreibt einen Anstieg der Energieaufnahme von 27 % über
die durchschnittliche Einsatzzeit eines Haushaltskältegeräts von 16 Jahren. Der
stärkste Anstieg erfolgt in den ersten fünf Betriebsjahren. Durch Diffusionsvorgänge
in dem im Gehäuse verbauten Polyurethan-Schaum wird das im Zellgas vorhandene
Kohlenstoffdioxid durch Luft ersetzt. Hierdurch steigt die Wärmeleitfähigkeit
des Schaums um ca. 33 % an, wodurch sich die Energieaufnahme der Geräte erhöht.
Des Weiteren wurde der Einsatz von Paraffinen als Phasenwechselmaterial in Haushaltskältegeräten
untersucht. Durch deren Einsatz konnte die Energieaufnahme gesenkt und die Funktionalität
der Geräte gesteigert werden. Hierfür sind detaillierte Kenntnisse der Materialkenndaten
der Paraffine notwendig. Die Wärmeleitfähigkeit der verschiedenen Paraffin-Stoffgruppen
in der festen Phase ist jedoch bisher nur unzureichend untersucht worden. Daher
wurde ein Messaufbau entwickelt, mit dem die Wärmeleitfähigkeit von festem Paraffin
bestimmt werden kann, und es wurden entsprechende Messungen durchgeführt.

text: The energy consumption of household refrigeration appliances has decreased
significantly since the 1990s. This value is determined by the manufacturers under
standard conditions when the appliances are new. However, like any other technical
system, these appliances are also subject to an aging process that leads to an
increase of energy consumption over the time of usage. As part of this thesis,
an aging model was developed on the basis of 100 standard energy consumption measurements
carried out on 32 appliances over a period of 21 years. This model is the first
to be developed on the basis of energy consumption data from real aged appliances.
It describes an increase of energy consumption by 27 % over 16 years, which is
the average period of use of a household refrigeration appliance. The largest
increase occurs in the first five years of use. Diffusion processes in the polyurethane
foam installed in the cabinet of the appliances result in an exchange of carbon
dioxide with air. This gas exchange increases the thermal conductivity of the
foam by approximately 33 %, which rises the energy consumption of the appliances.
Furthermore, the use of paraffins, as one type of phase change materials, in household
refrigeration appliances was investigated. The use of these materials made it
possible to reduce energy consumption and increase the functionality of the appliances.
This application of paraffins requires detailed knowledge of their material characteristics.
However, the thermal conductivity of paraffins in the solid state has so far only
been investigated insufficiently. Therefore, a measurement setup for determining
the thermal conductivity of solid paraffins was developed and corresponding measurements
were carried out.

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.

text: AbstractThe homogeneous density of the liquid
phase is experimentally investigated for methyl diethanolamine. Data are obtained
along five isotherms in a temperature range between 300 K and 360 K for pressures
up to 95 MPa. Two different apparatuses are used to measure the speed of sound
for the temperatures between 322 K and 450 K with a maximum pressure of 95 MPa.
These measurements and literature data are used to develop a fundamental equation
of state for methyl diethanolamine. The model is formulated in terms of the Helmholtz
energy and allows for the calculation of all thermodynamic properties in gaseous,
liquid, supercritical, and saturation states. The experimental data are represented
within their uncertainties. The physical and extrapolation behavior is validated
qualitatively to ensure reasonable calculations outside of the range of validity.
Based on the experimental datasets, the equation of state is valid for temperatures
from 250 K to 750 K and pressures up to 100 MPa.

text: The increase of the thermal conductivity of PUR foam in the insulation of
the cabinet is an important cause for aging processes of household refrigerating
appliances. To determine the influence of the PUR foam aging on energy consumption,
the development of a new measurement method is necessary be- cause current methods
influence the aging behavior of household refrigerators and are therefore not
applicable in general. Based on a latent heat sink, constructed as an ice water
bucket, a new measure- ment method is developed to determine the k ·A value over
time. With this method, the k ·A value of four household refrigerating appliances
was determined over an interval of 14 months. The k ·A value increased between
3.6% and 11.5% during this period.
