자기냉동 기술의 최근 동향

Recently, a near-room temperature proof-of-principle apparatus showed that magnetic refrigeration(MR) is a viable and competitive technology with conventional vapor compression refrigeration. Search for new material with improved magnetocaloric effect(MCE) led to the discovery of the giant MCE in Gd_5(Si_xGe_(1-x))₄ alloys. More recent research and development efforts have indicated that a high efficiency. rotary magnetic refrigerator using a Nd₂Fe₁₄B permanent magnet array as the magnetic field source could be used in household magnetic refrigerators/freezers and air conditioners.
