TEE are semi-conductor devices that can provide heating and cooling via a heat pump effect without direct noise emissions and no refrigerant use. An efficiency evaluation of the optimal operating mode is carried out for different numbers of TEE, ambient temperatures, and heating loads. The influence of an additional heat recovery unit on system efficiency and an unevenly distributed heating demand are examined. The results show that TEE can provide heat at a coefficient of performance (COP) greater than one especially for small heating demands and high ambient temperatures. The efficiency increases with the number of elements in the system and is subject to economies of scale. The best COP exceeds six at optimal operating conditions. An additional heat recovery unit proves beneficial for low ambient temperatures and systems with few TEE. It makes COPs above one possible at ambient temperatures below 0 ∘C. The effect increases efficiency by maximal 0.81 (from 1.90 to 2.71) at ambient temperature 5 K below room temperature and heating demand Q˙h=100W but is subject to diseconomies of scale. Thermoelectric technology is a valuable option for electricity-based heat supply and can provide cooling and ventilation functions. A careful system design as well as an additional heat recovery unit significantly benefits the performance. This makes TEE superior to direct current heating systems and competitive to heat pumps for small scale applications with focus on avoiding noise and harmful refrigerants.}, language = {en} } @article{GoettscheTammeNunez2005, author = {G{\"o}ttsche, Joachim and Tamme, Rainer and Nunez, Thomas}, title = {Speicherung f{\"u}r Hochtemperaturw{\"a}rme / Rainer Tamme ; Joachim G{\"o}ttsche ; Thomas Nunez}, series = {W{\"a}rme und K{\"a}lte - Energie aus Sonne und Erde : Jahrestagung des Forschungsverbunds Sonnenenergie in Kooperation mit der Landesinitiative Zukunftsenergie NRW / Stadermann, Gerd, Hrsg.}, journal = {W{\"a}rme und K{\"a}lte - Energie aus Sonne und Erde : Jahrestagung des Forschungsverbunds Sonnenenergie in Kooperation mit der Landesinitiative Zukunftsenergie NRW / Stadermann, Gerd, Hrsg.}, publisher = {Forschungsverbund Sonnenenergie}, address = {Berlin}, pages = {126 -- 131}, year = {2005}, language = {de} } @article{GoettscheSchwarzerRoetheretal.2009, author = {G{\"o}ttsche, Joachim and Schwarzer, Klemens and R{\"o}ther, S. and Jellinghaus, Sabine}, title = {Efficient daylighting, heating and shading with rooflight heliostats}, series = {Conference Internationale Energie Solaire et Batiment}, journal = {Conference Internationale Energie Solaire et Batiment}, publisher = {EPFL}, address = {Lausanne}, pages = {243 -- 248}, year = {2009}, language = {en} } @article{GoettscheRuss2005, author = {G{\"o}ttsche, Joachim and Russ, Christel}, title = {Energieversorgung in Niedrigstenergie-Neubauwohnungen / Christel Russ ; Joachim G{\"o}ttsche}, series = {W{\"a}rme und K{\"a}lte - Energie aus Sonne und Erde : Jahrestagung des Forschungsverbunds Sonnenenergie in Kooperation mit der Landesinitiative Zukunftsenergie NRW / Stadermann, Gerd, Hrsg.}, journal = {W{\"a}rme und K{\"a}lte - Energie aus Sonne und Erde : Jahrestagung des Forschungsverbunds Sonnenenergie in Kooperation mit der Landesinitiative Zukunftsenergie NRW / Stadermann, Gerd, Hrsg.}, publisher = {Forschungsverbund Sonnenenergie}, address = {Berlin}, pages = {93 -- 98}, year = {2005}, language = {de} } @article{GoettscheReillyWittwer1991, author = {G{\"o}ttsche, Joachim and Reilly, S. and Wittwer, Volker}, title = {Advanced window systems and building energy performance / S.

The concentrator consists of a mirror array, which was created using the application builder. The mirror facets are preconfigured to form a focal point. During tracking all mirrors are moved simultaneously in a coupled mode by 2 motors in two axes, in order to keep the system in focus with the moving sun. Optical errors on each reflecting surface were implemented in combination with the solar angular cone of ± 4.65 mrad. As a result, the intercept factor of solar radiation that is available to the receiver was calculated as a function of the transversal and longitudinal angles of incidence. In addition, the intensity distribution on the receiver plane was calculated as a function of the incidence angles.}, language = {en} }
