text: The influence of latent heat storage elements on the cooling performance and
the temperature rise time of household refrigerating appliances is studied experimentally
in the context of the “new global refriger- ator standard”IEC 62552:2015. In addition
to the daily energy consumption, this international standard- ization introduced
performance tests for cooling capacity and temperature rise time. While the cooling
capacity has long been anchored in various test procedures of consumer organizations,
the temperature rise time, which has only been tested on freezers so far, will
be a decisive factor in the future. Moreover, the need for so-called "smart appliances"
that may balance power consumption is increasing since such devices may compensate
the volatility of renewable energies and thus stabilize the power grid. Against
this background, eight commercial household refrigerators and refrigerator-freezers
are equipped with polymer-bound phase change materials (PCM) and their performance
is determined under the new stan- dard test conditions. The results show that
the introduction of PCM increases the cooling capacity by up to 33 % and also
increases the temperature rise time by up to 145 %, without affecting power consump-
tion, as compared to the unmodified refrigeration appliances.

text: Despite the omnipresence of household refrigeration appliances, there is still
a lack of knowledge about their agerelated efficiency loss over time. Past studies
provide basic evidence for increasing electricity consumption of cooling appliances
with ageing but fail to investigate the associated technical wear. Concentrating
on the degradation of the thermal insulation, we first determined the ageing process
of sealed samples of polyurethane rigid foam by investigating changes in cell
gas composition and thermal conductivity over time. Simultaneously, the main challenge
was to develop an approach that investigates the age-related efficiency loss of
the insulation without its destruction. This testing procedure is referred to
as the Bonn method. The non-destructive Bonn method was applied to varying refrigerator
models in a series of successive experiments to evaluate the insulation degradation
over time. Subsequently, the physical relationship between the test value of the
Bonn method and the heat transfer through the multi-layered compartment walls
of domestic refrigeration appliances was established, ultimately characterising
the degrading insulation in terms of increasing heat transfer. Our results give
substantiated evidence that the efficiency loss of cooling appliances is greatly
influenced by insulation degradation over time. The ageing of sealed samples of
polyurethane rigid foam indicates a large initial increase of thermal conductivity
by 15% within the first year, corresponding to a change in cell gas composition.
These results are in line with those of the Bonn method, emphasising an increasing
heat flow through the multi-layered compartment walls of domestic refrigerators
with ageing. Therewith, the present study is of significance to a wide range of
stakeholders and forms the basis for future research.

text: Due to the trend towards lightweight design in car body development mechanical
joining technologies become increasingly important. These techniques allow for
the joining of dissimilar materials and thus enable multi-material design, while
thermic joining methods reach their limits. Semi-tubular self-piercing riveting
is an important mechanical joining technology. The rivet production, however,
is costly and time-consuming, as the process consists of several process steps
including the heat treatment and coating of the rivets in order to achieve an
adequate strength and corrosion resistance. The use of high nitrogen steel as
rivet material leads to the possibility of reducing process steps and hence increasing
the efficiency of the process. However, the high tool loads being expected due
to the high strain hardening of the material are a major challenge during the
rivet production. Thus, there is a need for appropriate forming strategies, such
as the manufacturing of the rivets at elevated temperatures. Prior investigations
led to the conclusion that forming already at 200 °C results in a distinct reduction
of the yield strength. To create a deeper understanding of the forming behaviour
of high nitrogen steel at elevated temperatures, compression tests were conducted
in a temperature range between room temperature and 200 °C. The determined true
stress – true strain curves are the basis for the further process and tool design
of the rivet production. Another key factor for the rivet manufacturing at elevated
temperatures is the influence of the process temperature on the tribological conditions.
For this reason, ring compression tests at room temperature and 200 °C are carried
out. The friction factors are determined on the basis of calibration curves resulting
from the numerical analysis of the ring compression process. The investigations
indicate that the friction factor at 200 °C is significantly higher compared to
room temperature. This essential fact has to be taken into account for the process
and tool design for the rivet production using high nitrogen steel.

text: As a result of lightweight design, increased use is being made of high-strength
steel and aluminium in car bodies. Self-piercing riveting is an established technique
for joining these materials. The dissimilar properties of the two materials have
led to a number of different rivet geometries in the past. Each rivet geometry
fulfils the requirements of the materials within a limited range. In the present
investigation, an improved rivet geometry is developed, which permits the reliable
joining of two material combinations that could only be joined by two different
rivet geometries up until now. Material combination 1 consists of high-strength
steel on both sides, while material combination 2 comprises aluminium on the punch
side and high-strength steel on the die side. The material flow and the stress
and strain conditions prevailing during the joining process are analysed by means
of numerical simulation. The rivet geometry is then improved step-by-step on the
basis of this analysis. Finally, the improved rivet geometry is manufactured and
the findings of the investigation are verified in experimental joining tests.
