"An epidemic of moisture-related problems are causing more system failures today than ever before in the history of air conditioning and refrigeration," said Paul Appler a technical speaker at the State of Alabama's mandated Continuing Education Program for HVAC/R Contractors.

The choice of the magnetocaloric refrigerant is of great importance as it influences strongly the thermodynamic performances of the cooling machine. Pure gadolinium is the only material used in most magnetic refrigeration prototypes. 

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).
