In this paper, a new type of reciprocating magnetic refrigerator working with high remanence permanent magnets as the source of the magnetic field is presented. The simulated and measured magnetic field at the machine air gap is about 1.45 Tesla.  

A pleasant indoor climate and no energy costs. The ZERO+ house in Sønderborg is the first residential house in Denmark to produce more energy than is consumes, thanks to a range of energy saving initiatives along with a PV installation with a Danfoss ULX 5400o inverter.

90 % of refrigeration service companies, distributors and operators of refrigeration systems surveyed by DuPont at the end of 2009/ start of 2010 consider the future availability of reclaimed R22 to be “insufficient” or “acutely insufficient” to meet actual market needs.  

According to the International Institute of Refrigeration, 20% of the global warming potential of refrigerating and air-conditioning systems come from leaks (direct emissions), while 80% results from their energy consumption (indirect emissions).

Compressed air has become vital for day-to-day operations in most industries. Currently, the most commonly used compressors are oil-injected rotary screw. As the name suggests, it requires oil to operate. 

Maybe one of the keys to the solution of the climate changes lies in an invention, which is more than 60 years old? While the discussions leading up to COP15 have tended to focus on developing renewable energy, well-known technologies can already reduce the burden on the climate considerably.
