Abstract
The invention relates to a method for controlling the orientation of a sun collector (K1, K2, K3, K4), with a heat collecting element (10) respectively arranged in the focal line. The temperature and/or the heat quantity of the heat transfer medium flowing through the heat collecting element (10) are measured in the region of a sun collector (K1, K2, K3, K4) in such a way that they can be associated with same, and the determined temperature values (T1, T2, T3, T4; T′1, T′2, T′3; T′4, T′5) and/or heat quantity values are supplied to a control unit controlling the orientation of each sun collector (K1, K2, K3, K4) and orienting the respective sun collector (K1, K2, K3, K4) according to a determined orientation parameter. The method according to the invention comprises the following steps: a) the heat quantity collected in each sun collector is determined; b) an orientation parameter of each sun collector (K1, K2, K3, K4) is modified by an increment in the direction of the movement of the sun or a decrement away from the movement of the sun; c) the heat quantity collected in step a) is compared with the heat quantity collected in each sun collector after step b) has been carried out, and d) the orientation parameter modified by the increment or the decrement is stored as a new nominal value for the orientation control of each sun collector in the control unit, when it is determined that the heat quantity determined in step c) is higher than the heat quantity determined in step a).
