Cold spray (CS) deposition of a durable silver coating with high infrared reflectivity for radiation energy saving in the polysilicon CVD reactor

This paper for the first time presents a set of background, theory and practice of energy saving architecture of buildings that allows harmonization of appropriate thermal “behaviour” of the building itself with the energy saving behavioural actions of the people in it depending on year-round and daily dynamics of renewable energy of an environment and incoming solar radiation. Energy saving architecture offers a solution to the two-fold task of saving energy and ensuring acceptable internal conditions due to the beneficial influence of natural processes of the building and human behaviour. It is aimed to provide year-round acceptable parameters for the internal microclimate and sanitary-hygiene conditions and to minimize heating, cooling, and ventilation energy consumption. This paper presents the derivation of the formula on the dimensionless indicator of the building’s energy efficient form; its values of the real building forms; examples of solved computational optimization of the location, orientation, and size of the building, and its rooms and thermal envelope components (especially windows and doors). Considerations include issues of minimizing the effect of thermal bridges, especially architectural ones, as well as the structural and operational bridges from the author’s classification. The architectural, constructional, and operational practices are demonstrated by: passive gain and prevention of solar heating; heating and cooling by natural ventilation.

Under the background of energy saving and emission reduction, energy-saving renovation of kilns in ceramics industry has always been the key step to promote sustainable development strategy in ceramics industry, and also one of the key points for enterprises to reduce production costs. For the manufacturing enterprises of gongdao kiln in ceramics industry, the choice of refractory and heat preservation materials is one of the keys to manufacturing high efficiency and energy saving kilns. Through a series of technological innovations and development experiments, the researchers solved the problem of surface peeling of thermal radiation materials after sintering on the inner wall of kiln, and made the thermal radiation materials more widely used. This paper introduces the development process, physical and chemical characteristics, energy-saving principle and application methods of heat radiation energy-saving coatings, and lists specific examples for analysis. Through energy-saving comparative experiments and specific application cases, it shows that thermal radiation energy-saving coatings have great application prospects in the ceramic industry, and should be vigorously promoted to provide direction for energy-saving and emission reduction in the ceramic industry.

Summary: Different shapes of individual subjective discount functions were compared using real measures of willingness to accept future monetary outcomes in an experiment. The two-parameter hyperbolic discount function described the data better than three alternative one-parameter discount functions. However, the hyperbolic discount functions did not explain the common difference effect better than the classical discount function. Discount functions were also estimated from survey data of Dutch households who reported their willingness to postpone positive and negative amounts. Future positive amounts were discounted more than future negative amounts and smaller amounts were discounted more than larger amounts. Furthermore, younger people discounted more than older people. Finally, discount functions were used in explaining consumers' willingness to pay for an energy-saving durable good. In this case, the two-parameter discount model could not be estimated and the one-parameter models did not differ significantly in explaining the data.
