Il raffreddamento dei data center<\/strong><\/a> viene solitamente garantito da gruppi frigoriferi<\/strong><\/a> ad espansione diretta. Questi sistemi oltre ad essere alquanto energivori fanno uso di refrigeranti fonti di gas serra<\/strong>, sempre pi\u00f9 osteggiati dalle normative ambientali. La crescita della potenza computazionale correlata alla diffusione globale di intelligenza artificiale<\/strong>, big data analytics<\/strong>, cloud computing<\/strong><\/a>, machine learning<\/strong> e blockchain<\/strong> rende quindi il problema dell\u2019impatto ambientale dei data center sul global warming un\u2019emergenza da affrontare subito.<\/p>\n

Se da una parte l\u2019incremento delle temperature a cui i computer possono operare riduce la necessit\u00e0 di raffreddamento meccanico dei data center, dall\u2019altra le normative spingono a una drastica riduzione dell\u2019impiego di refrigeranti, responsabili di emissioni inquinanti.<\/p>\n

 <\/p>\n

I data center fanno impiego di diversi refrigeranti HFC<\/strong> (idrofluorocarburi), tra cui i pi\u00f9 comuni sono l\u2019R134a (usato negli impianti di grandi dimensioni) e l\u2019R410A (utilizzato nei siti di piccola e media grandezza). Il controllo della loro disponibilit\u00e0 a livello normativo sta portando ad un aumento dei loro prezzi. Ci\u00f2 impone agli operatori di data center di ricorrere a nuove tecnologie e strategie di raffreddamento Green dei data center<\/strong>.<\/p>\n

Tra queste vi \u00e8 il raffreddamento a immersione<\/a> con scambiatori TCOIL<\/a><\/strong> per il raffreddamento a liquido dei server<\/a>. Magari sfruttando anche la presenza di acqua a bassa temperatura disponibile nell\u2019ambiente (ad esempio acqua di fiordo come nell\u2019installazione Green Mountain in Norvegia). L\u2019eliminazione dei refrigeratori, oltre a eliminare il ricorso a gas fluorurati refrigeranti, in questo caso potrebbe anche consentire ai data center di operare a basso consumo energetico<\/strong>.<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Un\u2019altra strategia Green di raffreddamento dei data center \u00e8 quindi rappresentata dal free cooling<\/a><\/strong>, che come per gli scambiatori a immersione spicca sia per efficienza di raffreddamento che per sostenibilit\u00e0. Il free cooling<\/a>, che laddove possibile sfrutta le basse temperature ambientali esterne, rappresenta un\u2019ottimale opzione di raffreddamento in combinazione a sistemi ad acqua refrigerata (CW). La possibilit\u00e0 di potenziamento adiabatico<\/strong><\/a>, che estende l\u2019efficienza di dissipazione del sistema in free cooling, amplia infine le aree geografiche in cui \u00e8 possibile fare ricorso a questa soluzione Green di raffreddamento.<\/p>\n","protected":false},"excerpt":{"rendered":"
