Basic study about an air conditioner which combined the magnetic refrigeration technologies using superconducting magnets with humidity regulation system
The basic study about a highly effective and large scale magnetic refrigeration system using a superconducting magnet has been studied. We have conducted R&D to convert magnetic refrigeration technology, which uses magneto-caloric effect and is a highly-efficient, energy-conserving/environment-friendly technology, into practical application. The performance calculation for the magnetic refrigerator using superconducting magnets was already carried out, and we have obtained the result that COP of 5-8 is predicted when ΔH is 10 T. This value is as good as that of conventional air-conditioners. The possibility to apply the large scale air conditioner using the magnetic refrigeration technologies with superconducting magnets was confirmed. Recently, we propose a new humidity regulation system applying a magnetocaloric effect to the desiccant type humidity regulator. When magneto-caloric materials coated with the sorbent are heated by magnetizing, the moisture in the sorbent is released into the air. During demagnetization, the moisture in the air is adsorbed on the sorbent. In this paper, possibility to apply the highly effective and the large scale air conditioner which combined the room temperature magnetic refrigeration technologies using superconducting magnets with humidity regulation system applying a magnetocaloric effect is presented.
