\nThe origami microfluidic devices produce more surface convection because of their geometry and because they have more surface area than flat panels. As a result, lukewarm water instead of chilled water may be sufficient for cooling a room, leading to potential savings in primary energy use and lifecycle greenhouse gas emissions. Analytical models and physical experiments show a 55\u201367% improvement in thermal performance when comparing these novel folded surfaces to flat surfaces, mainly due to the improved convection heat transfer.<\/p>\n<\/div>\n<\/div>\n\n\n\n

At 75 W\/m2<\/sup>, a higher surface temperature [2C\u02da] increases global average Natural Ventilation Hours by 24%<\/p>\n<\/div>\n<\/div>\n\n\n\n Jonathan Grinham <\/p>\n<\/div>\n\n\n\n The origami microfluidic devices produce more surface convection because of their geometry and because they have more surface area than flat panels. As a result, lukewarm water instead of chilled water may be sufficient for cooling a room, leading to potential savings in primary energy use and lifecycle greenhouse gas emissions. Analytical models and physical experiments show a 55\u201367% improvement in thermal performance when comparing these novel folded surfaces to flat surfaces, mainly due to the improved convection heat transfer.<\/p>\n<\/div>\n<\/div>\n\n\n\n Grinham Research Group Harvard University Graduate School of Design Origami Microfluidics Radiant Cooling Project Overview Design and fabrication methods translated […]<\/p>\n","protected":false},"author":178,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_mi_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"class_list":["post-316","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"\n<\/figure>\n\n\n\nInnovation<\/h2>\n\n\n\n
