This can directly determine the effective thermal conductivity of the investigated area and allow the correct sizing of the planned closed geothermal system.<\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\">The main advantage of the method is that it directly provides thermal conductivity values along the entire borehole, taking into account local hydrogeological factors (presence of groundwater) and the physical properties of the surrounding sediment or rock (mineral composition, porosity, saturation, density, grain size), which can provide significantly different results than those obtained in the laboratory or in the field with a needle probe, as the measurements are carried out on a smaller sample size and consequently do not capture all relevant factors.<\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\">According to the German VDI standard and the Guidelines for shallow geothermal drilling up to 300 m depth (Prestor et al., 2021), the test is recommended for installations where more than 30 kW of power is planned, or if a larger array of geoprobes is planned.<\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\"><strong>Access to equipment of equipment<\/strong><\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\">Thermal Response Test<\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\"><strong>Equipment rental<\/strong><\/span>\n<\/p>\n<p style=\"margin-left:0cm\">\n    <span lang=\"SL\" dir=\"ltr\">It is possible to rent a service with operators.<\/span><\/p>","protected":false},"featured_media":939971,"template":"","class_list":["post-73764","infrastructure","type-infrastructure","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Test toplotnega odziva - GeoZS<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.geo-zs.si\/en\/infrastructure\/test-toplotnega-odziva\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Test toplotnega odziva - GeoZS\" \/>\n<meta property=\"og:description\" content=\"Opis opreme Proizvajalec: UBeG GmbH &amp; Co.
