<p>A solar thermal collector apparatus comprising at least one thermal collector module (11). Each thermal collector module (11) comprises a hollow container (2) having an inlet and an outlet. A flow controller is arranged between the hollow container (2) and an inlet main pipe and/or an outlet main pipe. Each thermal collector module (11) also comprises at least one temperature sensor (4) and/or a light illuminance sensor (3), and is in a communication connection to a control system for measuring the temperature and/or the incident illuminance value. The control system comprises a feedforward regulator unit, which, after analysis and computation on the basis of the temperature and/or the illuminance value of each hollow container (2), generates a feedforward regulating signal for regulating each flow controller, thus altering the flow rate and/or the flow velocity of an endothermic working medium of the corresponding hollow container (2), and allowing the endothermic working medium to reach a predetermined pressure and temperature at the outlet of each thermal collector module (11). The solar thermal collector apparatus ensures uniform pressure and temperature of the endothermic working medium at the outlet of each thermal collector module (11), and obviates control signal lag.</p> |
