    • The present invention provides systems and methods for transferring heat using a variable composition organic heat transfer fluid that remains liquid over a wide operating temperature range useful for solar heating applications. Variable composition heat transfer fluids of the present invention comprise a miscible mixture, optionally a completely miscible mixture, of a high boiling point component selected for its beneficial high temperature physical properties, and a low freezing point component selected for its beneficial low temperature physical properties. In some embodiments, the low freezing point component is removed from the heat transfer fluid as the heat transfer fluid is heated, for example by being removed in the vapor phase, thereby selectively varying the composition and physical properties (e.g., vapor pressure, boiling point, etc.) of the heat transfer fluid as a function of temperature.
    • 本发明提供使用可变成分的有机传热流体传递热量的系统和方法,所述有机传热流体在用于太阳能加热应用的宽工作温度范围内保持液体。 本发明的可变组合物传热流体包含由其有益的高温物理性质选择的高沸点组分的可混溶混合物,任选的完全可混溶的混合物,以及由其有利的低温物理性质选择的低凝固点组分。 在一些实施方案中,当传热流体被加热时,例如通过在气相中被除去,从传热流体中除去低凝固点组分,从而选择性地改变组成和物理性质(例如蒸气压,沸点 等)传热流体作为温度的函数。

    • 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.
    • 提供了包括至少一个太阳能集热器和压力调节模块的太阳能集热系统。 太阳能热收集器包括容器,密封容器的透光盖和多个太阳能热收集管。 太阳能热收集管安装在容器中,以便使传热材料流入其中。 太阳能热收集管的外表面相应地沉积有用于吸收太阳辐射能量的太阳能选择性涂层,将辐射能转换成热能,并将热能传递到在太阳热收集管中流动的传热材料。 压力调节模块通过调节太阳能热收集器内部的空气压力并控制空气循环的方向流入或流出太阳能集热器来控制太阳能集热器的热损失率。
