Premiere of cutting-edge cooling appliance at CES 2015
  • Haier, Astronautics, and BASF present the first prototype of a magnetocaloric wine cooler at the International Consumer Electronics Show in Las Vegas/Nevada
  • Partners demonstrate the functional principle of innovative technology for energy efficient cooling

Ludwigshafen, Germany and Las Vegas, Nevada, January 6, 2015. Haier, a leading global manufacturer of household appliances, Astronautics Corporation of America, a global technology company, and BASF, the world’s leading chemical company, present at the International Consumer Electronics Show (CES, Jan. 6 - 9) in Las Vegas, Nevada, a proof‑of‑concept wine cooler refrigerated by a magnetocaloric heat pump.

A magnetocaloric heat pump – a cooling device based on magnetocaloric materials – is an ideal alternative to traditional compressor-based refrigeration technology. Magnetocaloric materials heat up when put in a magnetic field and cool down when removed from the magnetic field. In the magnetocaloric heat pump, heat is transferred from the cold interior of the wine cooler to the warm surrounding air by shuttling a water‑based coolant through the magnetocaloric materials as they go in and out of the magnetic field.

One key to success is a class of functional materials based on manganese and iron developed by BASF and its partner Delft University of Technology, the Netherlands. “Together with our research colleagues who are well-experienced in functional materials as well as in systems solutions and modelling, we developed this innovative class of materials,” explains Andreas Riehemann, Managing Director of BASF New Business GmbH. “Together with our partners we can develop tailor-made functional materials for our customers’ cooling applications.” The magnetocaloric materials consist of abundant and affordable raw materials. They feature high performance across the whole range of temperatures relevant to refrigeration as well as high volume stability under operating conditions. BASF will sell these materials under the Quice® brand.

Astronautics provided the specialized expertise to integrate the new materials into the magnetocaloric heat pump. “By operating an integrated wine cooler prototype we demonstrate that magnetocaloric technology has the potential to revolutionize the cooling industry,” says Dr. Steven L. Russek, Director of the Astronautics Technology Center in Madison, Wisconsin. Using BASF’s magnetocaloric materials, Astronautics developed the magnetocaloric heat pump and along with Haier integrated it into the prototype wine cooler. Theoretical studies demonstrate that refrigeration systems based on the magnetocaloric effect can be up to 35% more energy-efficient than vapor compression systems. Furthermore, cooling systems based on magnetocaloric materials will operate with less noise due to the absence of a compressor. This technology makes use of water-based coolants instead of gaseous refrigerants.

Haier contributed their knowledge of household appliances and led the prototype development of the wine cooler which is now equipped with the magnetocaloric heat pump. “The investment in the world’s first magnetocaloric wine cooler symbolizes Haier’s determination to be truly customer-focused and forward-thinking,” says Dr. Tao Xie, Director of Disruptive Technology of the Haier America Tech Center in Evansville, Indiana. “We are constantly challenging ourselves for disruptive ways to deliver new user experiences and be socially responsible for the community and the environment. The magnetocaloric wine cooler prototype shows great promise to help our customers save energy, cut utility bills, and reduce operating noise. As an environmentally friendly technology that produces zero ozone depleting gases or greenhouse gases, it is a technology Haier is aggressively pursuing.” Haier plans to introduce the technology into the market within the next couple of years providing a compressor free cooling alternative. The partners plan to continue their cooperation to achieve this goal.
