Protocol to evaluate a (magneto)caloric device with static thermal switches using a 1D numerical model
Katja Vozel, Katja Klinar, Andrej Kitanovski
Izvirni znanstveni članek
Oznake: thermal switches;magnetic cooling;heat transfer;thermal management;modelling;
This protocol describes the use of a simple 1D numerical model to evaluate a single-stage (magneto)caloric refrigerating device with static thermal switches. The model can be used to find appropriate values of parameters that lead to a significant refrigerating effect and COP of the device. The mode ...

Oznake: solid thermal switch capacitors;thermal control devices;magnetocaloric cooling heat pump;
Compact, solid thermal control devices offer a new way to control the intensity and direction of heat flow between the components of a system, which is crucial for both optimized performance and safety. In this work we study a thin, silicon thermal switch capacitor (TSC) used for heat transport in a ...

Thermal control elements (TCEs) and thermal control circuits (TCCs) are a promising addition to conventional methods of thermal management, as they enable non-linear, switchable, and active control of heat. However, TCEs and TCCs are still at an early stage of development and are not yet ready for u ...

Ferrofluidic thermal switch in a magnetocaloric device
Katja Klinar, Katja Vozel, Timm Swoboda, Tom Sojer, Miguel Muñoz Rojo, Andrej Kitanovski
Izvirni znanstveni članek
Oznake: thermal switches;ferrofluids;magnetic cooling;heat transfer;thermal management;sensitivity analysis;
Thermal switches are advanced heat-management devices that represent a new opportunity to improve the energy efficiency and power density of caloric devices. In this study we have developed a numerical model to analyze the operation and the performance of static thermal switches in caloric refrigera ...

Small demonstrator of a thermoelectric heat-pump booster for an ultra-low-temperature district-heating substation
Urban Tomc, Simon Nosan, Boris Vidrih, Simon Bogić, Kristina Navickaite, Katja Vozel, Miha Bobič, Andrej Kitanovski
Izvirni znanstveni članek
Oznake: district heating;thermoelectrics;heat pump booster;energy efficiency;
Heating and cooling systems account for approximately 50% of global energy consumption and contribute 40% of carbon dioxide emissions. District-heating systems offer enhanced energy efficiency, diversification, independence from energy sources, and the utilization of waste and renewable energy sourc ...
