id=\"kuo-skiriasi-rekuperatorius-nuo-iprasto-vedinimo\"><strong>What is the difference between a recuperator and regular ventilation?<\/strong><\/h2>\n\n\n\n<p>Many people, lacking more knowledge about modern ventilation solutions, think that a recuperator and a conventional ventilation system are the same. However, in fact, they are two different solutions that differ in both their operating principle and efficiency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"iprastas-vedinimas\"><strong>Normal ventilation<\/strong><\/h3>\n\n\n\n<p><strong>Indoor ventilation is the process by which indoor air is removed to the outside and fresh air from the outside is supplied to the inside of the premises.<\/strong>The key task of a ventilation system is to ensure constant exchange of outdoor and indoor air, while simultaneously purifying the air of harmful substances. This exchange ensures the removal of carbon dioxide and air pollutants from the air.<\/p>\n\n\n\n<p>By the way, ventilation of rooms should not be confused with cooling, which is also often done. Devices such as air conditioners and fans can move air indoors, effectively reduce the temperature and ensure comfort, but they do not clean the air, so cooling should definitely not be equated with the operation of ventilation systems.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2240\" height=\"1260\" src=\"https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis.jpg\" alt=\"Natural ventilation through an open skylight\" class=\"wp-image-23909\" title=\"\" srcset=\"https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis.jpg 2240w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-300x169.jpg 300w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-1024x576.jpg 1024w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-768x432.jpg 768w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-1536x864.jpg 1536w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-2048x1152.jpg 2048w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-18x10.jpg 18w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-1200x675.jpg 1200w, https:\/\/orotech.lt\/wp-content\/uploads\/2025\/07\/atidarytas-stoglangis-150x84.jpg 150w\" sizes=\"(max-width: 2240px) 100vw, 2240px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"vedinimas-rekuperatoriumi\"><strong>Ventilation with a recuperator<\/strong><\/h3>\n\n\n\n<p>The recuperator also ensures the entry of fresh air from outside into the premises, but <strong>It differs from conventional ventilation in that it also warms the air coming in from outside, using as much of the heat energy already present in the premises as possible.<\/strong><\/p>\n\n\n\n<p>This is a very sustainable and economical solution, as the heat recovery unit ensures ventilation of the premises by returning a large part of the energy for reuse.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ieskote-kokybisko-rekuperatoriaus\"><strong>Are you looking for a quality recuperator?<\/strong><\/h2>\n\n\n\n<p>As we have already discussed, a properly selected heat recovery unit has a significant impact on indoor air quality and comfort.
