Magnetocaloric Material
Environmental Friendly Refrigeration with CALORIVAC
CALORIVAC® is a magnetocaloric alloy enabling solid state energy conversion such as magnetic refrigeration. It enables engineers to build gas-free magnetic refrigeration using magnetocaloric alloys as active materials
Benefits:
- Non-toxic, cost-efficient magnetocaloric alloy for magnetic refrigeration
- Enables the design of environmentally friendly, gas-free refrigeration and air-conditioning devices
- Future proof technology with no legislative pressure on the end-user
- Alternative areas of use are direct conversion of low-grade waste-heat in to electricity
- Active area of R & D with sample quantities available upon request
Details
Different machines for energy conversion are possible
- Refrigeration and air conditioning devices
- Mechanical energy required to turn a magnet is used to pump heat from a lower temperature level to a higher temperature level
- Low grade waste heat conversion
- Switching the magnetic state of the magnetocaloric material using hot and cold fluids electrical or mechanical energy can be generated
- Adiabatic temperature change of 2 to 4 K @ 1.5 T magnetic field change
- Entropy change of 5 to 20 J/kgK @ 1.5 T magnetic field change
- Magnetocaloric alloys covering a temperature range from 100 to 350 K enabling their use in a multitude of applications
- Thermal conductivity of about 8 W/mK
To satisfy the new F-gas regulation the refrigeration and air conditioning industry is suffering from the phase-down of hydrofluorocarbons. Magnetic refrigeration can offer a more energy efficient, completely gas-free and future proof alternative. By magnetizing and demagnetizing magnetocaloric alloys, heat can be moved from a colder temperature level to a higher temperature level – the classical principle of a heat pump or refrigerator.
