Refrigeration and air conditioning account for ~17% of global energy consumption, a figure expected to triple by 2050, while contributing over 10% of global greenhouse gas emissions. Conventional vapor-compression cooling relies on high–global-warming-potential refrigerants, creating an urgent need for energy-efficient and environmentally friendly alternatives.
Electrocaloric cooling is a promising solid-state technology that can be up to 20% more efficient than vapor-compression systems. It uses ferroelectric materials that undergo a reversible temperature change under an applied electric field. The materials heats upon application and cools upon removal of an electric field. This temperature change arises from an entropy variation induced by the electric field. The electrocaloric effect is strongest near the Curie temperature, where the material transitions from ferroelectric to paraelectric and the polarization changes most strongly with temperature. To date, EC research has largely focused on room-temperature operation, while low-temperature electrocaloric effects, down to liquid nitrogen temperatures remain largely unexplored.
The intern will investigate the electrocaloric effect in ferroelectric ceramics at low temperatures.
First, the work will include validating an existing low-temperature electrocaloric measurement setup using an infrared camera.
Second, the intern will characterize the electrical (ferroelectric) and thermal properties of the materials using, respectively, an electrical setup and a differential scanning calorimeter.
Finally, the intern will measure the electrocaloric response down to liquid nitrogen temperatures using an infrared camera and/or thermocouples.
