… is extracted usually by photovoltaic cells but also with the help of thermal processes. There are different types of solar cells in which crystalline silicon solar cells are the most common. Because I want a solar collector to cover a large part of the heating for hot water …
Produktutvecklingsprojekt för en effektivare och mer användarcentrerad metod för tillskärning av nätisoleringsmattor
… shaping wire-net insulation mats. This insulation product isused for fire and thermal insulation of technical installations. The insulation consists of stoneor glass wool with a sewn on steel wire netting on the out facing side. This netting has thepurpose to enable fastening to …
Detta examensarbete utreder lönsamheten i en systemlösning för termiskt akviferenergilager tillsammans med ny VVS-teknisk lösning i fastigheterna kv Hästskon 9 och 12 vid en föreslagen framtida helrenovering. Dessutom utreds förutsättningar för miljöklassning i energi- och …

… of sheet metal and the foundation wall is flawed as this has a much lower thermal resistance compared to other parts of the building envelope. An alternative connection was developed which reduces the heat loss to one-fifth of the initial connection. An analysis regarding the …
Detta examensarbete har utförts med begäran från Trafikförvaltningen. Arbetets huvudmål är att undersöka om det är möjligt att använda värmestrålning direkt mot ytan av strömskenan för att hindra isbildning på en kortare tid då absorptiviteten är som bäst.
… losses in the exhaust and cooling systems. By recovering and converting the thermal energy of a combustion engine to mechanical/electric power the efficiency of the combustion engine can be increased. In this work the performance of a truck engine has been investigated with the …
… constitute a much larger problem factor than the materials coefficient of thermal expansion. This resulted in the exclusion of one of the concepts. The right side was treated somewhat more briefly as it quickly became clear that the only thing that prevented from making the …
… includes the boreholes and necessary equipment for filtering and pumping the thermal water. The secondary circuit involves two paralleled series of heat pumps, a pellet boiler for peak production and a storage tank to even out the daily consumption variations. The system is then …
en ekonomisk utredning
Sverige är idag i starkt beroende av importerade oljeprodukter för att driva de dagliga transporter som krävs för att samhället ska fungera. Kraftigt ökade priser på olja, eller en slopad internationell oljehandel skulle få ödesdigra konsekvenser för Sverige. Samtidigt är …
En kvalitativ studie av en kommuns utformning av ungdomstjänst
… service as well as how and why the chosen design came to be. The result was thermalized with four topics: how is youth service designed? The reasoning behind Gothenburg’s design, the adjustment of the process of evaluating the suitability of the sentence youth service for the …

… available there are both physical, chemical, biological, electrical and thermal variants. Many of the treatments (except for carbonation and microbial bioleaching) results in chloride levels below the limits. Several are however unrealistically expensive or generate wastewater …
Konvektorers och nischdjupets inverkan på lufthastigheter i rummet
… that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often …
… It also shows that it is possible to combine the needles with a thermal activated pump (actuator) unit made of paraffin to transport liquid through the needles. Hence the experiments show that microneedles and actuator fulfil the fundamentals towards micro scaled drug …
