Durante l\u2019inverno \u00e8 per\u00f2 possibile <strong>sfruttare sistemi a scambio diretto<\/strong> grazie alle basse temperature ambientali. Si tratta di sistemi <a href=\"https:\/\/www.tempco.it\/blog\/7100\/dry-cooling-autodrenante-raffreddamento-economico-in-ogni-stagione\/\" target=\"_blank\" rel=\"noopener\">dry cooling o free cooling<\/a>, che consistono in batterie di scambio o grandi <strong>radiatori ventilati<\/strong> che permettono di raffreddare l\u2019acqua.<\/p>\n<p>La convenienza del sistema dipende da due fattori, in primo luogo la <strong>latitudine del sito di installazione<\/strong> dell\u2019impianto. In secondo, il livello di <strong>temperature dell\u2019acqua di raffreddamento richiesto<\/strong> dal processo industriale implicato.<\/p>\n<p><iframe loading=\"lazy\" width=\"750\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/kHOFRQhQZk8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>Ipotizzando di avere un processo che necessita acqua di raffreddamento a 15\u00b0 C, durante l\u2019estate sar\u00e0 indispensabile avere un chiller. In inverno, invece, o comunque <strong>quando la temperatura esterna scende al di sotto dei 10\u00b0 C<\/strong>, \u00e8 possibile avere acqua a 15\u00b0 C utilizzando un normale dry cooler. Ottenendo un <strong>notevole risparmio energetico<\/strong>: infatti si avr\u00e0 comunque l\u2019energia consumata per il <strong>pompaggio dell\u2019acqua<\/strong> e per il <strong>circuito di ventilazione<\/strong>, ma si potranno <strong>spegnere completamente i compressori<\/strong> del gruppo frigorifero. Che per un impianto ad esempio da 100 kW possono comportare un consumo energetico di circa 30 kW l\u2019ora. Il risparmio energetico ottenibile spegnendo i compressori sar\u00e0 quindi tanto maggiore quanto pi\u00f9 importanti sono le potenze termiche richieste.<\/p>\n<p>Occorre pertanto valutare sia le temperature richieste dal processo sia le temperature medie stagionali nel sito di installazione, onde valutare accuratamente e caso per caso il <strong>ritorno dell\u2019investimento dell\u2019implementazione di un sistema di free cooling<\/strong>.<\/p>\n<p>Per restare sempre informato sulle ultime applicazioni, iscriviti qui alla <a href=\"https:\/\/www.tempco.it\/newsletter-solid-temperature\/\" target=\"_blank\" rel=\"noopener\">Newsletter &#8211; Solid Temperature di Tempco<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La convenienza di implementare un sistema di free cooling combinato con gruppi frigoriferi nel raffreddamento di processi industriali dipende dalle temperature richieste dal processo e dalle temperature stagionali locali.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16,55,44,47,19,6,50,39,4,12,10],"tags":[1018,112,150,1350,1864,375,256,594,394,435,118,70,1543,1870,2026],"class_list":["post-8176","post","type-post","status-publish","format-standard","hentry","category-chiller","category-cooler","category-dissipatori","category-dry-cooler","category-free-cooler","category-free-cooling","category-pompaggio-dellacqua","category-radiatori","category-raffreddamento","category-refrigeratori","category-risparmio-energetico","tag-acqua-refrigerata","tag-chiller-2","tag-compressori","tag-consumo-energetico","tag-dry-cooling","tag-free-cooler","tag-free-cooling","tag-gruppi-frigoriferi","tag-pompaggio-acqua","tag-radiatori","tag-raffreddamento-2","tag-risparmio-energetico-2","tag-solid-temperature","tag-ventilatori","tag-ventilazione"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Quando implementare il free cooling \u00e8 davvero conveniente?
