energiflöden och kylning
This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess …
… considered the concept before. I would like to turn the focus from heating to cooling. Houses with large glass facades facing south and a closed climate shell risk too high an indoor temperature. How do we plan houses so that they don’t need a cooling system? Is protection from …
… PUE, is lacking some information. It is not able to compare different kinds of cooling solutions and it does not take in account the large amount of heat produced in a data center. This development and the limitations of the existing index calls for an improved way of measuring …
… on verifying whether the existing structure provides sufficient heating and cooling functions. Based on the validation review, the current prototype's performance is presented and suggestions for improvements are submitted.Knowledge in the relevant area has been acquired through …
… from industrial processes, primarily from the production hall leads to high cooling demand to maintain good thermal comfort. Limitations in operation control of the buildings HVAC (Heating, Cooling and Air-conditioning) systems causes high heating and cooling demand and hence …
Kartläggning av kylapotential för Vattenfall Värm
… the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today …
tensile properties of cast iron
… four points of view, carbon concentration, nodularity, amount inoculation and cooling rate. After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a. These results were plotted in different diagrams to show the relations …
… savings potential, but with low investment costs. Those are: Eliminate a cooling water flow to the hot water tankUse water in two positions without additional heatingOptimize the heat recovery towers by increasing the dew point One of the other losses that were identified was a …
… De teman som ligger till grund för analysen är: studie- och yrkesvägledning, cooling down, empowerment, informationsteorier, forskningslitteratur samt karriärvalsteorin SCCT. Studien visar att samtliga respondenter har utsatts för dämpande påverkan, cooling down, under sin …
… investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of …
