That\u2019s because these machines employ a delicate thermal cycle. The application are mostly in the <strong>HVAC sector<\/strong>, both for residential and industrial conditioning.<\/p>\n<p>But there are also machines with lower power capacities on the market, allowing to operate both in conditioning and <strong>production processes applications<\/strong>, being able to <strong>reach temperatures of -10\u00b0 C<\/strong>.<\/p>\n<p>Those are machines produced by <a href=\"https:\/\/www.robur.com\/\" target=\"_blank\" rel=\"noopener\"><strong>Robur<\/strong><\/a>, and Italian company that acquired many years ago the patent of this technology from an American company. These are in fact <strong>small size absorption refrigerators<\/strong>. The standard range of these machines employs a direct fired burner which provides the heat required to trigger the <strong>thermal cycle for cold production<\/strong>.<\/p>\n<p><iframe loading=\"lazy\" width=\"750\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/RsBHJKn4lpI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>A very interesting and smart idea that fascinated me is to <strong>leverage waste heat coming from industrial production<\/strong> to start that same thermal cycle. The company has in fact modified its machines to integrate a sort of <a href=\"https:\/\/en.tempco.it\/solutions-en\/heat-exchangers\/\" target=\"_blank\" rel=\"noopener\"><strong>heat exchanger<\/strong><\/a>, which allows to work using waste heat coming from industrial processes, waste steam or diathermic oil at the end of a process.<\/p>\n<p>The interesting thing is the extension of an <strong>energy recovery approach for the production of cold<\/strong>, leveraging energy that otherwise should be lost and dissipated.<br \/>\nThe only limit I see here is that this application requires <strong>waste heat at very high temperature levels<\/strong>, between <strong>190\u00b0 C and 220\u00b0 C<\/strong>. And it\u2019s not easy to find waste heat at this temperature, but in case it is available the solution becomes surely extremely interesting and intriguing.<\/p>\n<p>I\u2019m thinking about applications where there is a <strong>continuous generation of waste heat<\/strong>, allowing the continuous production of cold. A kind of solution that could then be very interesting in a wide variety of applications, such as on <a href=\"https:\/\/www.tempco.it\/blog\/en\/6768\/exhaust-heat-recovery-in-cogeneration-with-shell-and-tube-exchangers\/\" target=\"_blank\" rel=\"noopener\"><strong>waste fumes from cogeneration plants<\/strong><\/a>, or fumes coming from <a href=\"https:\/\/www.tempco.it\/blog\/en\/6189\/temperature-regulation-on-steel-mill-fournace-gases\/\" target=\"_blank\" rel=\"noopener\"><strong>steel industries of metallurgy plants<\/strong><\/a>, where high amounts of high quality energy is available, meaning high temperature waste heat.<\/p>\n<p>Subscribe here to our <strong><a href=\"https:\/\/en.tempco.it\/newsletter-solid-temperature\/\" target=\"_blank\" rel=\"noopener\">Tempco Newsletter &#8211; Solid Temperature<\/a><\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Energy recovery applied in cold production, using waste heat in small size absorption chillers that allows high energy savings where waste heat at high temperature is available. <\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[79,64,73,63,143],"tags":[175,112,388,442,177,126,967,74,2365,138,785,537,194,2367,176,2366,1543,893,1082],"class_list":["post-7679","post","type-post","status-publish","format-standard","hentry","category-cogeneration","category-cooling","category-energy-saving","category-heat-exchangers","category-heat-recovery","tag-absorption-chiller","tag-chiller-2","tag-cogeneration","tag-cold","tag-conditioning","tag-energy-efficiency","tag-energy-recovery","tag-energy-saving-2","tag-fumes-recovery","tag-heat-exchangers-2","tag-high-temperatures","tag-hvac","tag-industrial-processes","tag-production-processes","tag-refrigeration","tag-robus","tag-solid-temperature","tag-steel-industry","tag-waste-heat"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
