基于太阳能光伏光热系统,研究相变胶囊,采用相变胶囊的功能性流体参与换热,设计了一种提供电力和热水的光伏光热系统。在此基础上,通过配比相变材料,制备相变胶囊的功能性流体,用于储存太阳能的热量。太阳能光伏光热系统,在提高光伏效率的同时,能得到低温的热水,通过热泵,再次提高热水的温度,实现家庭电力热水的供应。

Starting from the introduction of solar photovoltaic photothermal system, this paper studies a phase change capsule, which uses a functional fluid of phase change capsule to participate in heat transfer, and designs a photovoltaic photothermal system that provides electricity and hot water. On this basis, the functional fluid of the phase change capsule is prepared by proportioning the phase change material, thereby storing the heat of the solar energy. Secondly, designing a solar photovoltaic photothermal system can not only improve photovoltaic efficiency, but also obtain low temperature hot water. Finally, the heat pump is used to raise the temperature of the hot water again to realize the supply of household electric hot water.
