Solar thermal collecting system
A solar thermal collecting system, including at least one solar thermal collector and a pressure-adjusting module, is provided. The solar thermal collector includes a container, a light-transmissive cover that seals the container, and a plurality of solar thermal collecting pipes. The solar thermal collecting pipes are installed in the container, so as to allow a heat transfer material to flow therein. The outer surfaces of the solar thermal collecting pipes are correspondingly deposited with solar selective coatings for absorbing solar radiation energy, transforming the radiation energy into thermal energy, and transmitting thermal energy to the heat transfer material flowing in the solar thermal collecting pipes. The pressure-adjusting module controls the heat loss rate of the solar thermal collector by adjusting the air pressure inside the solar thermal collector and controlling the direction of air circulation to flow in or out of the solar thermal collector.
