Le pompe di calore sono state valutate in termini di efficienza, prestazioni del sistema di sbrinamento e capacit\u00e0 di operare in un clima freddo.<\/b><\/p>\n<p class=\"parastd\">I risultati mostrano che le pompe di calore sono diventate pi\u00f9 efficienti dal 1991 al 2001. In media, il coefficiente di prestazione (COP) \u00e8 aumentato di 7-24 % dal 1991. Anche i sistemi di sbrinamento sono migliorati, anche se esistono ancora sistemi che in pratica funzionano con un semplice controllo a tempo e quindi eseguono inutilmente molti cicli di sbrinamento, riducendo le prestazioni e probabilmente anche la durata delle apparecchiature.<\/p>\n<p class=\"parastd\">\n<p class=\"parastd\"><a href=\"\/it\/script\/tool\/forg\/doc66\/HPC-NL_4_2006_p18-25.pdf\/\" target=\"_blank\" ><\/p>","protected":false},"excerpt":{"rendered":"<p>Feb. 05, 2007 &#8211; Twelve variable-speed capacity controlled air-to-air heat pumps have been evaluated by laboratory measurements and the results [&hellip;]<\/p>","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[29],"tags":[28],"faqcat":[],"class_list":["post-1641","post","type-post","status-publish","format-standard","hentry","category-heating-knowledge","tag-heat-pump"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/posts\/1641","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/comments?post=1641"}],"version-history":[{"count":0,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/posts\/1641\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/media?parent=1641"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/categories?post=1641"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/tags?post=1641"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/faqcat?post=1641"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
