Funny bomber jacket made of functional materialDetachable hood with synthetic fur (We only use animal-friendly vegan fur. The fur trimming are detachable for easy cleaning.) The sparkling frontal 2-way zip is a real eye-catcher. Outer jacket and lining made of technical fabric. The jacket has sealable outer pockets, and it also has a sealable inner pocket for your mobile phone. On the front, there is a continuous sparkling 2-way zip with wind protection. Even when we are not doing any sports at all, our body is generating heat, and we begin to sweat. A healthy adult produces 200 to 700 ml of sweat on average on a daily basis. It goes without saying that this is higher when you engage in physical exercise or during the summer. In order to keep our body temperature at a comfortable level and to keep sweat levels on the skin as low as possible, a jacket must have good ventilating properties as well as breathability. The material of the Funny Facts bomber jacket can absorb up to 1000 g of steam within 24 hours per square metre, and it has the ability to transfer this to the outside. An ISO standard says that water-tight textiles must have a water column of at least 1,300 mm. In a lab, a tube is placed on a sample of the fabric to be examined, and after this, the tube is filled with water. This process checks which water level penetrates the fabric. This means that, if the water only penetrates the fabric at more than 1,300 mm, the material is deemed water-tight. The Funny Facts bomber jacket only lets water through from 3,000 mm.

The industrial sector is very promising for the use of solar thermal technology, since it accounts for a large share of the total final energy consumption (e.g. 27 % in Germany in 2010) and it predominantly uses the consumed energy as thermal energy (74 % in Germany in 2010). In order to develop this area of application, it is necessary to understand which industrial sectors have the highest potential, which processes within these sectors are most suitable for the integration of solar heat as well as to quantify the possible contribution to the industrial heat demand. For this thesis, the industrial heat consumption in Germany is analyzed, which leads to the selection of the 11 most promising sectors within industry. These are Chemicals, Food and beverages, Motor vehicles, Paper, Fabricated metal, Machinery and equipment, Rubber and plastic, Electrical equipment, Textiles, Printing and Wood. The theoretical potential of solar heat for industrial processes below 300 °C in Germany adds up to 134 TWh per year, the technical potential (considering efficiency measures, limited roof area and a solar fraction) being 16 TWh per year or 3.4 % of the overall industrial heat demand.Solar thermal systems can achieve higher system yields in industrial applications compared to domestic ones. At the same time, systems can be more complex in industrial applications. In order to design and operate solar process heat systems efficiently and to exploit the large potential, possible faults of such systems and their impact have to be evaluated. In this thesis, an implemented solar process heat system is methodically analyzed based on measurements and simulations with a validated model. Several faults are identified and their influence, as well as the influence of a reduced load on the system yield is evaluated. The analysis shows that a reduced load is most influential. Further, the most important impact factors on the system performance are identified: the collector parameters (?0, a1) and load characteristics (mass flow, temperature). The design of solar process heat systems is in many cases very demanding, hence costly. This high effort is a major barrier for a further development of solar heat for industrial applications. The decision to install solar thermal systems is in most cases based on solar heat generation cost. Collector field and heat store size are the most important figures for the estimation of the overall cost of a solar thermal system. Therefore, a simple approach for dimensioning the collector field and heat store is developed in this thesis in order to enable manufacturers and planners on one hand and costumers on the other hand to make a decision in favor or against a solar process heat system. In addition to investment cost, the specific system yield, which is determined for selected process heat applications in this thesis, is necessary to calculate solar heat generation cost. Finally, indications on the necessary accuracy of the load profile are provided to help to reduce effort in the design phase.
