Efficient Compressor To Splash Aircon Power Use

The International Energy Agency (IEA) says fans and aircons already represent an astonishing 10 percent of global electricity consumption, but as billions more homes in hot areas install alternating current, power demand for these gadgets is set to skyrocket, Loz Blain reported for New Atlas.

So compressor efficiency is set to be a very big deal in the coming decades, and by proxy, that makes Magtor's Magtorpressor a device worth looking into – because this Maltese company claims its demonstrator units are already delivering 90 percent more pressure than the average air compressor for the same power consumption and some 29 percent more than the best current devices on the market.

“How? Well, Magtor does away with the rotating crank and piston assembly used by today's standard reciprocating designs, replacing it with a much simpler linear oscillating design capable of compressing air in both directions as it moves back and forth. Essentially, two round magnetic plates are joined at the middle by a connecting rod designed to transmit magnetic forces in both directions. These run through the middle of a large stator, the same diameter as the plates. The two plates joined by the rod comprise the single moving part in this design; there are no bearings or lubrication required,” Blain explained.

When a voltage is applied to the stator, it'll push this large double-sided piston in one direction or the other, depending on the polarity of the voltage. So if you plug it into alternating current, or switched single-phase DC, the pushing force will change directions many times per second and the piston will start moving rapidly back and forth.

Magtor calls it "the world's first high-energy bi-directional linear electric motor," and stresses that this is not an "unrolled" stator/rotor combination, nor does it use permanent magnets moving inside the electromagnet as with other linear motor designs.
