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. - lang: eng 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. author: - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul citation: ama: Paul A.

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. article_number: '117992' author: - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: Elmar full_name: Baumhögger, Elmar id: '15164' last_name: Baumhögger - first_name: Andreas full_name: Elsner, Andreas id: '16124' last_name: Elsner - first_name: Michael full_name: Reineke, Michael id: '24603' last_name: Reineke - first_name: Christian full_name: Hueppe, Christian last_name: Hueppe - first_name: Rainer full_name: Stamminger, Rainer last_name: Stamminger - first_name: Heike full_name: Hoelscher, Heike last_name: Hoelscher - first_name: Hendrik full_name: Wagner, Hendrik last_name: Wagner - first_name: Ulrich full_name: Gries, Ulrich last_name: Gries - first_name: Wolfgang full_name: Becker, Wolfgang last_name: Becker - first_name: Jadran full_name: Vrabec, Jadran last_name: Vrabec citation: ama: Paul A, Baumhögger E, Elsner A, et al.

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. article_number: '10' author: - first_name: Tobias full_name: Neumann, Tobias last_name: Neumann - first_name: Elmar full_name: Baumhögger, Elmar id: '15164' last_name: Baumhögger - first_name: Roland full_name: Span, Roland last_name: Span - first_name: Jadran full_name: Vrabec, Jadran last_name: Vrabec - first_name: Monika full_name: Thol, Monika last_name: Thol citation: ama: Neumann T, Baumhögger E, Span R, Vrabec J, Thol M.

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. author: - first_name: Gerrit full_name: Sonnenrein, Gerrit last_name: Sonnenrein - first_name: Elmar full_name: Baumhögger, Elmar id: '15164' last_name: Baumhögger - first_name: Andreas full_name: Elsner, Andreas id: '16124' last_name: Elsner - first_name: A. full_name: Morbach, A. last_name: Morbach - first_name: Moritz full_name: Neukötter, Moritz id: '45530' last_name: Neukötter orcid: 0000-0001-9101-8828 - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: J. full_name: Vrabec, J. last_name: Vrabec citation: ama: Sonnenrein G, Baumhögger E, Elsner A, et al.

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. article_number: '115113' author: - first_name: Christian full_name: Hueppe, Christian last_name: Hueppe - first_name: Jasmin full_name: Geppert, Jasmin last_name: Geppert - first_name: Rainer full_name: Stamminger, Rainer last_name: Stamminger - first_name: Hendrik full_name: Wagner, Hendrik last_name: Wagner - first_name: Heike full_name: Hoelscher, Heike last_name: Hoelscher - first_name: Jadran full_name: Vrabec, Jadran last_name: Vrabec - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: Andreas full_name: Elsner, Andreas id: '16124' last_name: Elsner - first_name: Wolfgang full_name: Becker, Wolfgang last_name: Becker - first_name: Ulrich full_name: Gries, Ulrich last_name: Gries - first_name: Alfred full_name: Freiberger, Alfred last_name: Freiberger citation: ama: 'Hueppe C, Geppert J, Stamminger R, et al.
