Magnetic refrigeration

The award of a $2.9m energy grant to Astronautics Corp of America will be used to develop the next generation of an air conditioning system using magnetic refrigeration technology.

This uses special alloys combined with a magnetic field to create temperature changes, replacing conventional compressors and refrigerants.

The company plans to create a prototype providing 3.5 kW of cooling power, with a manufactured version due in five years.
