Installation of free cooling and what costs it implies (Engelska)
Abstract [en]

In this work, a refrigeration centre with the use of free-cooling has been projected, drawn and then cost-calculated. The work began drawing a flowchart for the cooling system in the cooling centre, this flowchart were drawn in a program called Autodesk Autocad. After that, the work continued by drawing and projecting the cooling centre with the reality of a threedimensional modeling. This projection was done in Autodesk Autocad´s MagiCAD plug-in. Meanwhile when these flowcharts and model drawings were constructed, communication with manufacturers and suppliers of the major machines in the system was done parallel with the modeling. This was made to get the correct values, measurements and budget sacrifices. Once both the flowchart and the three-dimensional, realistic looking model were completed, a product calculation was initiated in Wikells Sektionsdata. The calculation includes all products in the entire refrigeration centre, as well as things that were previously unpublished. Examples of items that were not in the flowchart nor the three-dimensional model, but included in the product calculation are welding work, bolt joints, primary and secondary works. A product calculation was made for the system both with and without free-cooling, just to see how much the free-cooling installation will cost. The result was that the freecooling installation will cost 1 225 725 SEK. Subsequently, calculations were made to see how profitable it is for the company to invest in free-cooling. These calculations were made largely from an energy calculation from Ramböll. With those calculations, there was a result in the form of payback time. The payback time for free-cooling was calculated to just under 8,3 years.
