Traditionally that heat is dumped outdoors through cooling towers and chillers. With energy costs climbing, operators are asking a simple question: can that heat be used instead of wasted?<\/p>\n<h2>Two Main Recovery Paths<\/h2>\n<p>La premi\u00e8re voie est la r\u00e9cup\u00e9ration air-air. L'air de la all\u00e9e chaude passe par un \u00e9changeur air-air \u00e0 plaques ou rotatif pour r\u00e9chauffer l'air frais entrant ou les espaces voisins. Pour la r\u00e9cup\u00e9ration sensible en environnement de centre de donn\u00e9es, les \u00e9changeurs \u00e0 plaques et les unit\u00e9s \u00e0 \u00e9vaporation indirecte (IEC) sont le choix courant. Les roues rotatives sont g\u00e9n\u00e9ralement \u00e9vit\u00e9es ici en raison du risque de contamination crois\u00e9e et de fuite entre les flux d'arriv\u00e9e et d'\u00e9vacuation.<\/p>\n<p>La seconde voie est bas\u00e9e sur l'eau. La chaleur des serveurs est transf\u00e9r\u00e9e dans une boucle d'eau et distribu\u00e9e aux r\u00e9seaux de chauffage urbain ou aux b\u00e2timents voisins. Cela fonctionne mieux dans les villes denses et froides o\u00f9 la demande de chaleur est stable.<\/p>\n<h2>Why the Timing Is Right<\/h2>\n<ul>\n<li>Co\u00fbts \u00e9nerg\u00e9tiques : chaque kilowatt-heure r\u00e9cup\u00e9r\u00e9 en est un de moins achet\u00e9 au r\u00e9seau.<\/li>\n<li>Objectifs ESG : r\u00e9utiliser la chaleur transforme un flux de d\u00e9chet en un gain de durabilit\u00e9 report\u00e9.<\/li>\n<li>R\u00e9gulation : certaines r\u00e9gions exigent d\u00e9sormais que les grands \u00e9quipements r\u00e9cup\u00e8rent ou rapportent la chaleur gaspill\u00e9e.<\/li>\n<li>Chauffage urbain : les partenariats avec les services publics rendent la r\u00e9utilisation pratique \u00e0 l'\u00e9chelle de la ville.<\/li>\n<\/ul>\n<h2>What to Specify<\/h2>\n<p>Pour la r\u00e9cup\u00e9ration c\u00f4t\u00e9 air, choisir des \u00e9changeurs \u00e0 plaques ou l'IEC pour la chaleur sensible et garder les flux d'arriv\u00e9e et d'\u00e9vacuation s\u00e9par\u00e9s. Pour la r\u00e9cup\u00e9ration c\u00f4t\u00e9 eau, dimensionner la boucle pour la charge partielle plut\u00f4t que le pic, et la prot\u00e9ger par une filtration adapt\u00e9e. Quelle que soit la voie, associer l'\u00e9changeur \u00e0 un comptage pour que l'\u00e9nergie r\u00e9cup\u00e9r\u00e9e puisse \u00eatre mesur\u00e9e et report\u00e9e.<\/p>\n<h2>Outlook<\/h2>\n<p>Attendez-vous \u00e0 ce que la r\u00e9cup\u00e9ration passe des projets pilotes \u00e0 la conception par d\u00e9faut dans les nouvelles constructions de centres de donn\u00e9es. \u00c0 mesure que les r\u00e9seaux se d\u00e9carbonent et que la demande de chaleur reste \u00e9lev\u00e9e, transformer la chaleur r\u00e9siduelle en ressource partag\u00e9e sera l'un des gains les plus clairs du calcul efficace.<\/p>\n<div class=\"yc-related\">\n<h3>Articles connexes<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/hr-vs-erv-differences\/\">VRC vs. VRE : la diff\u00e9rence qui d\u00e9termine le confort de votre b\u00e2timent<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/data-center-support-space-heat-recovery\/\">R\u00e9cup\u00e9ration de chaleur des espaces annexes de centres de donn\u00e9es : bureaux, laboratoires et quais<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/heat-recovery-ventilation-retrofit\/\">Retrofitting Heat Recovery Ventilation into Older Buildings<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/run-around-coil-design-guide\/\" title=\"Syst\u00e8mes \u00e0 bobine en boucle interm\u00e9diaire : r\u00e8gles de conception pour flux d&#039;air s\u00e9par\u00e9s\">Syst\u00e8mes \u00e0 bobine en boucle interm\u00e9diaire : r\u00e8gles de conception pour flux d'air s\u00e9par\u00e9s<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/marine-product-drying-waste-treatment-heat-recovery-unit-corrosion-resistant-stainless-steel\/\" title=\"Marine Product Drying &amp;amp; Waste Treatment Heat Recovery Unit \u2013 Corrosion-Resistant Stainless Steel\">Marine Product Drying &amp;amp; Waste Treatment Heat Recovery Unit \u2013 Corrosion-Resistant Stainless Steel<\/a><\/li>\n<\/ul>\n<\/div>\n<h2>Questions fr\u00e9quemment pos\u00e9es<\/h2>\n<p><strong>Why recover heat from data centers?<\/strong><br \/>Almost all the electricity a data center draws ends up as heat.

Where higher-grade heat is available, heat pumps or Organic Rankine Cycle units can lift it for district heating or power.<\/p>\n<p><strong>Why are rotary wheels often avoided in data centers?<\/strong><br \/>Rotary wheels rotate exhaust and supply through a shared matrix, so a small amount of contaminated exhaust can carry into the clean supply air, a risk most operators avoid in IT spaces.<\/p>\n<p><strong>What can the recovered heat be used for?<\/strong><br \/>Nearby office or lobby heating, domestic hot water, greenhouses, swimming pools, or district heating networks where the data center sits close to heat demand.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Data Center Heat Problem Data centers use a large share of the world&#8217;s electricity, and almost all of it ends up as heat.
