摘要： Method of forecasting heat output of a solar collector. First, heat output for a plurality of solar collectors is simulated, located at respectively different geographic locations but having the same solar collector settings as the solar collector to be forecasted. The simulation is performed by calculating a dataset of theoretical heat outputs for the plurality of solar collectors, based on acquired related weather data. From the calculated dataset a function is adjusted, the function defining the theoretical heat output of any solar collector related to its geographic location, e.g. latitude, solar Direct Normal Irradiation, DNI, and collector settings, e.g. operation temperature, and forecasting the heat output of the solar collector based on the adjusted function. When traditional methods for estimating heat output require substantial amounts of measurements and processing capacity, the proposed method may instead enable an efficient and appropriate method of producing precise estimations of heat output.

摘要： Method of manufacturing a spectrally selective surface. The method comprises cleaning an outside of a tubular substrate, e.g. by sonicating in acetone, polishing the cleaned outside, and depositing a Co—Cr coating on the polished outside, i.e. the tubular substrate's outside. The Co—Cr coating comprises Co(II) compounds and Cr(III) compounds but no Cr(VI) compounds. By applying a DES electrolyte Cr(III)-ions may be solved in the electrolyte such that a receiver tube arranged in the electrolyte may become coated with a selective Co—Cr coating from Cr(III)-ions, where the optical characteristics regarding absorptance and emittance for the resulting receiver tube are comparable or surpasses traditional black chrome. Thereby use of harmful hexavalent chrome could be avoided, which may achieve more healthy and environmental friendly conditions. Particularly, no harmful Cr(VI)-ions or rest substances comprising them will contaminate ambient air or need to be handled or disposed.

摘要： An arrangement for manufacturing a reflector for a PTC from a rectangular reflective structure. The arrangement comprises a tensioning device configured to tension a reflector portion of the rectangular reflective structure, such that a surface of the tensioned reflector portion acquires a curvature perpendicular to the tensioned reflector portion's longitudinal propagation, along the tensioned reflector portion's longitudinal propagation. The arrangement further comprises a fixating device configured to fixate the surface's curvature, such that the tensioned reflector portion remains tensioned. The tensioning device is configured to tension the reflector portion of the rectangular reflective structure by pre-forming the reflector portion to a pre-curvature, and adjusting the pre-curvature by applying a torque at a longitudinal borderline of the pre-formed portion. Because the reflector will be maintained tensioned by torques only, it will adapt a curvature of a high precision parabola.

摘要： The logistics arrangement comprises an arm adapted to be pivotably attached to a logistics stand. The arm comprises a support member adapted to carry an object, when the arm is substantially horizontally directed in a storage position, and a pivoting means adapted to pivotably attach the arm to the logistics stand, such that the arm is enabled to pivot between the storage position and a standby position where the arm is substantially vertically directed. The arm also comprises a stop member adapted to together with the logistics stand hold the arm in a storage position. The support member is connected with the stop member and the pivoting means, and the arm is configured to be forced into the standby position by an upwardly directed lift-movement of the another located object, during unload of the lower located object form the logistics stand. The invention also relates to a logistics stand comprising a plurality of logistics arrangements, a logistics system comprising a freight container and at least one logistics stand, and a method for unloading objects from a logistics stand.

摘要： A holder for securing a fluid tube to a trough-formed solar collector. In an operation mode of the solar collector, the holder partly encircles a circumference of a cross-section of the fluid tube and leaves a portion of the circumference un-encircled by the holder. The holder may comprise a base member adapted to abut the fluid tube, the base member comprising at least one securing means adapted to secure the base member to the solar collector. Further, the holder may comprise an immobilizing member adapted to together with the base member immobilize a centre-line of the fluid tube in the solar collector when the fluid tube abuts the holder. The base member is connected with the immobilizing member, such that the base member together with the immobilizing member, in an operation mode of the solar collector, partly encircles the circumference of the cross-section of the fluid tube and forms an opening smaller than a diameter of the cross-section of the fluid tube. The immobilizing member may be pivotably connected to the base member by a connecting means, such that the immobilizing member can pivot in relation to the base member to, in a service mode of the solar collector, leave an opening larger than the diameter of the cross-section of the fluid tube.

摘要： An end seal arrangement for a Parabolic Trough solar Collector, PTC, comprises an elongated parabolic reflector trough and a receiver pipe arranged at a focus-line of the reflector trough. The end seal arrangement comprises a housing configured to be fixated to one short-end of the reflector trough, and an inlay configured to be inserted in the housing to slidably abut a circumference of the receiver pipe, such that the reflector trough is sealed to the receiver pipe by the inlay when the housing is fixated to the short-end of the reflector trough and the reflector trough pivots about its focus-line. The end seal arrangement further comprises a fixation means configured to fixate the housing to the reflector trough. By reducing heat leakage and prevent ice, snow, sand, etc. from deteriorating the reflector, improved operational performance will be achieved.

摘要： The solar tracking arrangement enables a plurality of parallel arranged PTCs to be directed towards the travelling sun. The solar tracking arrangement comprises a drive means, a transmission means, and a plurality of conversion means. The transmission means are connected with the drive means and to each of the plurality of conversion means. The transmission means is configured to convey an operating movement caused by the drive means to the plurality of conversion means, and each of the conversion means is configured to convert the conveyed operating movement into a pivoting movement of a respective one of the plurality of PTCs about a focus line, such that each of the pivoting movements directs the respective PTC towards the travelling sun. One or more of the conversion means are adjustably connected with the transmission means in a direction along the transmission means.
