Kelix Energies has developed a heating and cooling system that performs effectively without the use of a refrigeration compressor. Cooling systems can only operate if the refrigerant is maintained at a constant high pressure, a task performed by high-maintenance, inefficient compressors in conventional systems. By replacing compressors with a process called Centrifugal Heat Transfer (CHT), Kelix have reduced the amount of electricity needed for effective cooling and created a system with fewer moving parts that's less susceptible to mechanical failure.

CHT technology creates the necessary pressure differential via centrifugal force - heat transfer is achieved as the refrigerant passes from the condenser section, through a throttling device, and into the evaporator section.

The highly scalable Kelix heat transfer system allows the use of a wide variety of environmentally safe refrigerants at lower amperage rates. Combined with minimal space requirements and the ability to operate independently of any internal combustion engine, the Kelix system has the potential to dramatically expand air-conditioning applications at home, in the office and in automobiles.

"...a task performed by high-maintenance, inefficient compressors in conventional systems."
So, lasting 20-30 years without maintenance is "high maintenance?"
The inefficiencies of standard home refrigerators are largely due to the fact that consumers in the USA anyway, are largely indifferent to efficiency, so manufacturers were too. Most designs could easily be made much more efficient by adding insulation, and rearranging the access so that the machine doesn't dump all the cold air out every time the door opens.
Note that they announced this "new" technology in 2001.
This process may be more efficient, but compressor efficiencies aren't the driver for home refrigeration.
For commercial and large scale operations, or vehicle cooling this could be a game changer...though you could build a solar powered heat driven system...
