VERFAHREN ZUM BETRIEB EINES KOLLEKTORENSYSTEMS FUER SONNENSTRAHLUNG UND EINRICHTUNG ZUR DURCHFUEHRUNG DES VERFAHRENS

摘要

A modular solar collector system and method for solar radiation with a collector assembly defining a fluid flow channel therein exposed to solar radiation; a heat transfer fluid for flowing down the fluid flow channel to be heated directly or indirectly by the solar radiation where the heat transfer fluid has a fluid vapor pressure differential between the maximum and minimum temperatures to which said heat transfer fluid is exposed during flow down the fluid flow channel of less than about 0.3 psia and/or defines a wetting angle with respect to said solar radiation absorbing surface of less than about 50 DEG ; and means for supplying the heat transfer fluid to the upper end of the channel for the flow of the heat transfer fluid down the channel under the force of gravity to heat the transfer fluid.
