At least one major appliance maker plans to commercialize magnetic refrigeration for use in the home. The rationale for the change is that the technology uses no refrigerants or compressors and is said to be 20% more efficient than conventional techniques. It could also work well in HVAC.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/energy/magnetic-refrigeration-heats" target="_blank">read more</a></p> http://machinedesign.com/energy/magnetic-refrigeration-heats#comments Energy Sustainable Engineering Fri, 21 Mar 2014 14:23:00 +0000 35601 at http://machinedesign.com
