Real Calculation"},"content":{"rendered":"<p>An industrial warehouse needs between <strong>150 and 250 frigories per square meter<\/strong>, not the 100fg\/m\u00b2 applied in residential spaces. The difference is determined by ceiling height, thermal load from machinery, building envelope insulation, and whether the space remains open or closed during working hours. However, if the goal is not to cool the entire warehouse but to protect workers at their workstations, the calculation is radically different: a <a href=\"https:\/\/blizzcool.es\/aire-acondicionado-industrial\/\">portable industrial air conditioner<\/a> of 3,500-5,300 frigories is enough to effectively cool one or two fixed workstations, without needing to size the entire warehouse.  <\/p>\n<h2>Why the 100 Frigories per m\u00b2 Rule Doesn&#8217;t Work in a Warehouse<\/h2>\n<p>The 100fg\/m\u00b2 rule is designed for spaces with 2.5-meter ceilings, well insulated, without internal heat sources, and with moderate occupancy. An industrial warehouse violates all those assumptions at once: <\/p>\n<ul>\n<li><strong>Height:<\/strong> industrial warehouses have ceilings from 5 to 12 meters. The greater the air volume, the more power needed. Above 4 meters in height, the calculation must be done by cubic meters, not square meters.  <\/li>\n<li><strong>Operating machinery:<\/strong> a press, milling machine, furnace, or welder generates constant heat that adds to the thermal load. Every 1 kW of electrical power consumed by a machine generates approximately 860 frigories\/hour of residual heat that must be extracted. <\/li>\n<li><strong>Metal enclosures:<\/strong> metal sheeting accumulates and transfers heat much more efficiently than insulated brick or concrete in a residential building. A warehouse with an uninsulated metal roof can double the thermal load compared to a well-constructed warehouse. <\/li>\n<li><strong>Open doors:<\/strong> many warehouses operate with industrial doors open, eliminating any possibility of maintaining cold air inside with a centralized system.<\/li>\n<\/ul>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5729 size-large\" src=\"https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-1024x572.png\" alt=\"Blizzcool portable industrial air conditioner in workshop with industrial machinery in background\" width=\"1024\" height=\"572\" srcset=\"https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-1024x572.png 1024w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-300x167.png 300w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-768x429.png 768w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-600x335.png 600w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool-64x36.png 64w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/aire-acondicionado-industrial-spot-cooler-blizzcool.png 1376w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/h2>\n<h2>Frigories per m\u00b2 Table for Industrial Warehouse<\/h2>\n<table>\n<thead>\n<tr>\n<th>Warehouse Type<\/th>\n<th>Frigories\/m\u00b2<\/th>\n<th>Equivalent in kW\/m\u00b2<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Well-insulated warehouse, no heavy machinery, closed doors<\/td>\n<td>120 \u2013 150 fg\/m\u00b2<\/td>\n<td>0.14 \u2013 0.17 kW\/m\u00b2<\/td>\n<\/tr>\n<tr>\n<td>Standard warehouse, light machinery, occasional openings<\/td>\n<td>150 \u2013 200 fg\/m\u00b2<\/td>\n<td>0.17 \u2013 0.23 kW\/m\u00b2<\/td>\n<\/tr>\n<tr>\n<td>Warehouse with heavy machinery, welding, furnaces, or forging<\/td>\n<td>200 \u2013 300 fg\/m\u00b2<\/td>\n<td>0.23 \u2013 0.35 kW\/m\u00b2<\/td>\n<\/tr>\n<tr>\n<td>Semi-open warehouse or with frequently open doors<\/td>\n<td>Calculation not valid for fixed system<\/td>\n<td>Use spot cooler per workstation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>To convert frigories to kW: divide frigories by 860. To convert to BTU: multiply frigories by 3.97. <\/p>\n<h2>How to Calculate Your Warehouse&#8217;s Frigories Step by Step<\/h2>\n<p>The base formula for an industrial warehouse is: <strong>m\u00b2 \u00d7 height (m) \u00d7 thermal load factor<\/strong>. The factor ranges from 50 to 80 depending on warehouse type (equivalent to calculating by cubic meters with an adjusted coefficient). <\/p>\n<p>Practical example: 300 m\u00b2 machining warehouse with 6-meter height and operating CNC machinery.<\/p>\n<ul>\n<li>Volume: 300 m\u00b2 \u00d7 6 m = 1,800 m\u00b3<\/li>\n<li>Load factor (moderate machinery): 65<\/li>\n<li>Total frigories: 1,800 \u00d7 65 = 117,000 fg\/h<\/li>\n<li>In kW: 117,000 \u00f7 860 = ~136 kW cooling capacity<\/li>\n<\/ul>\n<p>That is the sizing to cool the entire warehouse. It requires a large-scale centralized installation. <\/p>\n<h2>The Calculation No One Does: Cool the Workstation, Not the Warehouse<\/h2>\n<p>In most workshops and manufacturing warehouses, the real problem is not that the entire warehouse is at 40\u00b0C: it&#8217;s that the worker at their welding, machining, or assembly station works at temperatures that affect their performance and safety. The difference is important because it completely changes the sizing. <\/p>\n<p>An <a href=\"https:\/\/blizzcool.es\/aire-acondicionado-industrial\/\">industrial spot cooler<\/a> of 5,300 frigories\/hour directs an airflow of 900 m\u00b3\/h of cold air directly to the workstation, creating a comfort zone with a 4 to 6-meter radius. In a workshop with five workers at fixed stations, five units of this type solve each worker&#8217;s thermal problem at a fraction of the cost of cooling the entire 300 m\u00b2 warehouse. Installation is zero: plug them in and they work the same day.  <\/p>\n<p>This approach doesn&#8217;t work if the production process requires temperature and humidity control throughout the entire space (food, pharmaceutical, precision electronics). For those cases, complete warehouse sizing is unavoidable. But for machining workshops, welding, metal carpentry, or logistics, cooling the workstation is almost always the fastest, cheapest, and most flexible solution.  <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5728 size-large\" src=\"https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-1024x572.png\" alt=\"Three workstations in industrial warehouse each with an individual Blizzcool spot cooler\" width=\"1024\" height=\"572\" srcset=\"https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-1024x572.png 1024w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-300x167.png 300w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-768x429.png 768w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-600x335.png 600w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool-64x36.png 64w, https:\/\/blizzcool.es\/wp-content\/uploads\/2026\/06\/nave-con-aires-industriales-portatiles-de-blizzcool.png 1376w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h2>Blizzcool: Power for the Workstation That Needs It Most<\/h2>\n<p>The Blizzcool spot cooler range covers from 1,900 to 5,300 frigories\/hour, with one or three directional air ducts to concentrate cold air at the exact workstation.
