Method for reducing urban heat island effect by using PCM
The invention relates to a method for reducing an urban heat island effect by using PCM (Pulse Code Modulation), which comprises the following steps of: obtaining a PCM-mixed concrete plate through a method I or a method II, and applying the PCM-mixed concrete plate to a road surface to prevent the temperature of the road surface from rising; the first method comprises the steps that core-shell packaging PCM is used, a metal pipeline is filled with the core-shell packaging PCM, the metal pipeline filled with the core-shell packaging PCM is embedded into a concrete plate, and the concrete plate mixed with the PCM is obtained; the second method comprises the following steps: adsorbing PCM by using a porous carrier material to obtain PCM with a stable shape, and mixing the PCM with the stable shape with concrete to obtain a concrete slab mixed with the PCM; the pavement temperature can be reduced by adding the solid-liquid PCM into the pavement, when the pavement temperature reaches the phase change temperature or above, the phase change is generated by absorbing the pavement heat energy, and the pavement temperature can be reduced, so that the urban heat island effect is relieved.
本申请涉及一种使用PCM降低城市热岛效应的方法，包括以下步骤：通过方法一或方法二得混合有PCM的混凝土板，将所述混合有PCM的混凝土板应用在路面，阻止路面温度上升；方法一：使用核壳封装PCM，将核壳封装PCM填充至金属管道，将充满核壳封装PCM的金属管道埋入混凝土板，得到混合有PCM的混凝土板；方法二：使用多孔载体材料吸附PCM，得到形状稳定的PCM，将形状稳定的PCM与混凝土混合，得到混合有PCM的混凝土板；本申请通过在路面中加入固‑液PCM可以降低路面温度，当路面温度达到相变温度以上时，相变通过吸收路面热能发生相变，并有助于路面温度的降低，从而缓解城市热岛效应。
