text: The aging behavior of closed-cell polyurethane (PUR) foam, a material widely
used in household refrigeration, is studied by examining the variation of cell
gas composition and thermal conductivity over time. Aging is primarily driven
by gas permeation, wherein the initially present cell gases carbon dioxide and
cyclopentane are progressively replaced by nitrogen and oxygen from the ambient,
resulting in an increased thermal conductivity and reduced insulation performance.
The cell gas composition is measured over 1400 days employing gas chromatography,
and the thermal conductivity of the foam is measured over 190 days. Morphological
foam characteristics, such as average cell diameter, are determined via scanning
electron microscopy and barrier measurements are performed to estimate the effective
diffusion coefficient of oxygen. To simulate the aging process, one-dimensional
and three-dimensional models are developed for both diffusive mass transfer as
well as heat transfer. The present model for the thermal conductivity explicitly
accounts for condensation effects, i.e. partial condensation of cyclopentane and
carbon dioxide occurring at around 12°C, which significantly influences the insulation
behavior of the foam. Sensitivity analyses indicate that an initial cell gas pressure
of approximately 0.7 bar yields results that closely coincide with the experimental
measurements, where the three-dimensional model demonstrates better accuracy.
These measurements and simulations provide valuable insights for evaluating and
predicting the long-term degradation of the insulation performance of PUR foams.

text: "In Haushaltskältegeräten werden in den letzten Jahren immer häufiger Vakuumisolationspaneele
(VIP) eingesetzt. Hiermit ist es unter anderem möglich, dass die Geräte in die
Energieeffizienzklassen A bis C klassifiziert werden können. Ein VIP besteht vereinfacht
aus einer Schutzfolie, die nahezu gasdicht ist und einem Füllmaterial, welches
für die Formstabilität im Vakuum zuständig ist. Aufgrund von technischen Alterungsprozessen
kommt es mit der Zeit zu einem Anstieg des Innendrucks im VIP, wodurch die Wärmeleitfähigkeit
des VIP steigt. Je nach Füllmaterial erfolgt dieser Alterungsprozess unterschiedlich
schnell. Im Extremfall kann so ein neues Haushalts-kältegerät der Energieeffizienzklasse
A nach 1 bis 3 Jahren nur noch als Klasse D bis F eingestuft werden.\r\nInnerhalb
eines Forschungsprojekts wurden Haushaltskältegeräte mit VIP thermografisch untersucht.
Im Rahmen dieser Studienarbeit wurde ein Versuchsaufbau entwickelt, mit dem die
zeitliche Veränderung von Wärmebrücken begutachtet werden kann und so Rückschlüsse
auf den Effizienzverlust der Geräte möglich sind. Der Funkionsnachweises dieses
Versuchsaufbaus wurden an einem Haushaltskältegerät mit künstlich gealterten Vakuumisolationspaneelen
durchgeführt. Diese Arbeiten bieten zukünftig die Möglichkeiten Haushaltskältegeräten
mit VIP bezüglich ihres Degenerationsverhaltens besser zu beurteilen.\r\n"

text: AbstractThe incorporation of heteroatoms
into the framework of polycyclic aromatic hydrocarbons (PAHs), in particular of
nitrogen to yield polycyclic aromatic nitrogen heterocycles (PANHs), has been
proposed for both astronomical and combustion environments, but no suitable precursors
and pathways have been found. Analogous pathways to PAH formation are kinetically
or energetically inhibited in the presence of a nitrogen heteroatom. We report
on the reaction of phenylnitrene (3PhN, c‐C6H5N)
with resonance‐stabilized propargyl radicals (C3H3)
and find that the association reaction bifurcates depending on the orientation
of the attacking propargyl radical and yields multiple isomeric products. Among
them, we identify the condensed‐ring quinoline and conclude that nitrenes are
viable candidates to drive the formation of PANHs.

text: In spray-flame synthesis of nanoparticles, a precise understanding of the
reaction processes is necessary to find optimal process parameters for the formation
of the desired products. Coupling the chemistries of flame, solvent, and gas-phase
species initially formed from the particle precursor in combination with the complex
flow geometry of the spray flame means a special challenge for the modeling of
the reaction processes. A new burner has been developed that is capable to observe
the reaction of precursor solutions frequently used in spray-flame synthesis.
The burner provides an almost flat, laminar, and steady flame with homogeneous
addition of a fine aerosol and thus enables detailed investigation and modeling
of the coupled reactions inde-pendent of spray formation and turbulent mixing.
With its two separate supply channel matrices, the burner also enables the use
of reactants that would otherwise react with each other already before reaching
the flame. These features enable the investigation of a wide range of flame-based
synthesis methods for nanoparticles and, due to the flat-flame geometry, kinetics
models for these processes can be developed and validated. This work describes
the matrix burner development and its gas flow optimization by simulation. Droplet-size
dis-tributions generated by ultrasonic nebulization and their interaction with
the burner structure are investigated by phase-Doppler anemometry. As an example
for nanoparticle-for ming flames from solutions, iron-oxide nanoparticle-generating
flames using iron(III) nitrate nonahydrate dissolved in 1-butanol were investigated.
This effort includes measurements of two-dimensional maps of the flame temperature
by a thermocouple and height-dependent concentration profiles of the main species
by time-of-flight mass spectrometry. Exper-imental data are compared with 1D simulations
using a reduced reaction mechanism. The results show that the new burner is well
suited for the development of reaction models for precursors supplied in the liquid
phase usually applied in spray-flame synthesis configurations.& COPY; 2022 The

text: Polycyclic aromatic hydrocarbons (PAHs) are formed in fuel-rich and sooting
hydrocarbon flames. These compounds and smaller aromatic flame constituents, such
as benzene, toluene and naphthalene can be detected by flame-sampling molecular
beam mass spectrometry (MBMS). They are readily ionized by photoionization with
UV light, either in resonant or non-resonant ionization processes. The multiphoton
ionization of benzene, toluene, and styrene with MBMS detection was investigated
as a function of laser power and wavelength and the quantitative relation between
ion signal and mole fractions in the flames was established. These measurements
were prerequisites for the measurement of quantitative mole fraction profiles
of these species in flames of various fuels. In addition, the measurements provide
relative mole fraction profiles of various other aromatic flame species. The results
are compared to measurements of aromatics in butadiene, propyne, and allene flames
by single-photon ionization with vacuum ultraviolet radiation from a synchrotron
source and other literature data. (c) 2023 Published by Elsevier Inc. on behalf

text: The technical importance of paraffins as phase change materials (PCM) in heat
storage systems increases. Knowledge on the thermal conductivity of paraffins
is necessary for the design and optimization of heat storage systems. However,
for most paraffins solely the thermal conductivity of the liquid state has been
sufficiently investigated. For the solid state, precise thermal conductivity data
are only known for a few paraffins, while only generalized values are available
for the remainder, some of which contradict each other. In this study, a measurement
setup based on the modified guarded hot plate method is developed. It is used
to investigate the thermal conductivity of several paraffines in the solid state,
including pure n-docosane and its compounds with different types and concentrations
of graphite. For n-docosane in the solid state, the thermal conductivity is determined
to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out
to be optimal to increase the thermal conductivity. This allows the thermal conductivity
of a compound with 10% graphite to increase by a factor of three compared to the
pure paraffin. Furthermore, significant differences to thermal conductivity data
from the literature are found.

text: "Die für die Berechnung des Energieeffizienzindex von Haushaltskältegeräten
benötigten Parameter werden durch Norm-Messungen im Neuzustand der Geräte bestimmt.
Aus früheren Untersuchungen ist bekannt, dass durch verschiedene technische Alterungsmechanismen
der Energieverbrauch über eine Produktlebensdauer von 18 Jahren um bis zu 33 %
zunehmen kann. Ziel des vom BMWi geförderten Projekts ALGE war es, die verschie-denen
Ursachen und Einflussgrößen für die Alterung von Haushaltskältegeräten zu ermitteln
und eine Alterungs-funktion zu bestimmen, die den zeitlichen Verlauf des zunehmenden
Energieverbrauchs beschreibt.\r\nIn diesem Projekt wurde das Alterungsverhalten
von Haushaltskältegeräten durch 100 Normenergieverbrauchs-messungen an 32 real
gealterten Geräten untersucht. Aus den gewonnenen Ergebnissen konnte eine Alterungs-funktion
bestimmt werden, die den Anstieg des Energieverbrauchs beschreibt. Alle untersuchten
Geräte wurden an der Universität Paderborn im Neuzustand vermessen und nach einer
Laufzeit von bis zu 21 Jahren erneut geprüft. Bereits nach einem zweijährigen
Betrieb konnte ein Mehrverbrauch von bis zu 11 % festgestellt werden. Über die
durchschnittliche Produktlebensdauer von Haushaltskältegeräten von ca. 16 Jahren
steigert sich der Energieverbrauch um durchschnittlich 27 %.\r\nIm Rahmen des
Projekts wurden verschiedene Systemkomponenten, wie Isolierung und Verdichter,
hinsichtlich ihres Alterungsverhaltens untersucht. Bei dem im Gehäuse als Isolierung
verwendeten PUR-Schaum konnte über einen Zeitraum von 31 Monaten ein Anstieg der
Wärmeleitfähigkeit von 19,5 W/(m⋅K) auf 24,5 W/(m⋅K) festge-stellt werden. Zur
Untersuchung der Alterung der Verdichter wurden zuvor auf einem Kalorimeterteststand
ver-messene Verdichter in Geräte eingebaut. Nach einem zweijährigen Betrieb wurden
diese Verdichter wieder aus-gebaut und erneut vermessen. Hierbei konnte keine
Änderung des COP festgestellt werden. Zusätzlich zu den technischen Parametern
wurde der Einfluss des Verbraucherverhaltens analysiert. Hier zeigte sich, dass
bis zu 33 % des Gesamtenergieverbrauchs nach einer mehrjährigen Nutzungsdauer
verbraucherinduziert sein können."

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.
