The article is kinda technical, so wrote a simplified explanation of the process.
___________________________________

In this new technology, a magnetic field magnetically orders the material at ambient temperature, which raises its temperature above ambient. The excess heat is removed through a thermal medium, such as water or air, bringing the material back to ambient temperature. The magnetic field is then removed, the material becomes magnetically disordered and its temperature drops below ambient temperature leading to a cooling effect. This "solid state" cooling process is significantly more energy efficient than the conventional, compressed gas systems currently on the market today.

This process has been demonstrated on small scale for years. In fact it appeared in Forbidden Planet!

The red rings in the lower dome was, in effect, this process. It has different labels but physicists call it the Thompson Effect; named after William Thompson, 1st Baron Kelvin (more commonly "Lord Kelvin") in 1851.
