摘要:
AbstractUse of secondary energy sources has a growing importance to supply of energy. The utilization of corresponding heat source potentials frequently requires the adaptation of time or power difference by means of heat storage units. Recent heat storage methods are based on the utilization of reaction heats of reversible reactions or latent heats of phase transformations. Presently, latent heat storage units have the best possibilities of realization. In the range of normal temperatures between 0–120°C storage densities of 200–600 MJ/m3are obtained on the basis of the phase change liquid‐solid at the melting point of salt hydrates. Mainly kinetic hindrances owing to phase separation, supercooling and heat transport are to be considered for application as a latent heat storage material. Internationally given solutions prefer stabilized compounds in static latent heat storage units. In contrast, with that, in the G.D.R. the dynamic latent heat storage method called „Galisol”︁ has been developed which allows optimum energy yields in narrow temperature ranges of about 10 K with high heat transfer powers. Among the developed 9 substance combinations in the temperature range between 25°C and 120°C up to now technical storage units with working temperatures of 30°C and 60°C have been realized. Various reference plants show the possibilities of application and the technical and economic advantages compared with the traditional heat

摘要:
AbstractAdvanced high‐vacuum technology enables the reproducable production of evaporated dye layers (EDL). By means of separate sources even the production of multilayers or homogeneous mixtures, e.g. dyes mixed with other evaporable organic or inorganic compounds as metal halides or oxides (“norganics”), is possible. Pure and mixed EDL's show a lot of specific electrical and optical properties which can be used in different fields of application, e. g. charge transfer and generation processes in information recording and solar storage, color microfilters and optical data storage. The survey resumes recent results of authors and literature
