Abstract:
The paper presents a test stand to study the magnetocaloric effect. The stand utilises a magnetocaloric material, gadolinium, as a refrigerant. This material was chosen, because of good magnetocaloric properties and suitable work temperature close to the room temperature. The magnetic field of 1 T is generated by cylindrical Halbach array which is a special arrangement of permanent magnets that concentrate and homogenize the magnetic field in the inner gap of the flux source. As a heat transfer medium a special liquid was selected. In addition, the paper provides first results from an investigation. Results amounted to 1.6 ºC temperature difference between hot and cold heat exchanger.
