A concept for the application of a magnetocaloric device in energy-efficient air conditioners is introduced. In order to evaluate this concept, test stand has been developed equipped with magnetic field source providing about 1.5-T flux density change into which different regenerator geometries can be implemented and evaluated. processing route production profiled LaFeSiMn-based composite plates by tape casting presented. The processed show maximum isothermal entropy 3.8 J kg − 1 K at 1.5 T...
The following article describes an extract of the results experimental investigations on topic thermal comfort as a function radiation asymmetry. were carried out in climate chamber [1, 2] TU Dresden with help subjects. asymmetry was imprinted by subdividing into two vertically superimposed half-rooms, one which heated and other cooled. In this way, 46 experiments heating or cooling ceiling out. measurement show inseparable link between asymmetry, vertical air temperature difference...
Lighting is a fundamental requirement of our daily life, especially for human circadian rhythm. The light could affect humans either positively or negatively, even if it does not get in contact with the eyes. A lot researches and development carried out field daylight harvesting, which order day. One most desirable attributes harvesting that available universally cost-efficient form energy. impact ambient temperature on its perception also considered. Daylight sense lighting strategy control...
Thermal comfort is a very important issue for the design of HVAC systems. The aspects thermal are also significant in operation heating/cooling systems rooms. Many investigations studied stationary boundary conditions, while transient conditions were not focus. Therefore, this paper describes measurements carried out climate room under conditions. After an introduction, second part gives overview about experimental setup and methodology dynamic investigations. third main results analyzes....
Abstract Der Einfluss der Strahlungsasymmetrie auf die thermische Behaglichkeit wird in Fachwelt jüngster Zeit wieder kontrovers diskutiert. Die den Vorschriften wie z. B. DIN EN ISO 7730 [1] / 16798‐1 [2] verankerten Grenzwerte lassen sich ausgewählten Fällen deutlich überschreiten, ohne dass dies von Nutzern als unbehaglich empfunden [3, 4]. In anderen hingegen ist tatsächliche Nutzerakzeptanz geringer vorhergesagt. Um grundlegenden Zusammenhänge zwischen unterschiedlichen, dem Menschen...
Surface heating and cooling systems are gaining more importance in building energy technology. In order to implement these not only on the floor but also ceilings walls, thermodynamic requirements supplemented by constructional requirements. fulfil requirements, use of open-cell porous metals for such will be investigated detail. addition design manufacturing challenges, a large number numerical experimental investigations test samples necessary. These described explained detail following article.
Currently available energetic evaluation methods for heat pump and micro-CHP systems lead to results which partly deviate strongly from field measurements. A new method based on the Hardware-in-the-Loop concept was therefore developed tested in a research project. The employs representative days. procedure determining days is presented. functionality of could be proven round robin test key figures can confirmed by values measurements values.
