本实用新型第一实施例所述的一种带相变蓄热的单罐蓄热装置的使用方法，包括：The method for using a single-tank heat storage device with phase change heat storage described in the first embodiment of the utility model includes:
蓄热过程：来自太阳能集热器14的高温传热介质经传热介质入口16进入单罐蓄热器2内底部的蓄热盘管换热器10将热量传递给单罐蓄热器2内的蓄热介质，温度降低，降温后的传热介质由传热介质出口12返回太阳能集热器14，完成一轮循环；蓄热介质从蓄热盘管换热器10吸收热量后温度升高，升温后的蓄热介质流过相变蓄热装置7，将热量传递给相变蓄热装置7中管排管内的相变蓄热介质，当单罐蓄热器2内的蓄热介质温度大于相变蓄热装置7中管排管内的相变蓄热介质熔点时，相变蓄热介质融化，将相变潜热储存起来，同时单罐蓄热器2内蓄热介质温度升高。此时罐内蓄热介质的流动方向如图2所示，在浮升力的作用下，蓄热介质向上流动，推动上部冷流体沿着所述单罐蓄热器2的顶部流过放热盘管换热器3所在的环形通道，推动冷流体沿环形通道向下运动，在单罐蓄热器2的底部吸收供蓄热盘管换热器10提供的热量，直至整个蓄热器内蓄热介质温度升高，完成蓄热过程。Heat storage process: the high-temperature heat transfer medium from the solar collector 14 enters the heat storage coil heat exchanger 10 at the bottom of the single-tank heat accumulator 2 through the heat-transfer medium inlet 16 to transfer heat to the single-tank heat accumulator 2 The temperature of the heat storage medium decreases, and the cooled heat transfer medium returns to the solar collector 14 from the heat transfer medium outlet 12 to complete a cycle; the temperature of the heat storage medium rises after absorbing heat from the heat storage coil heat exchanger 10 , the heated heat storage medium flows through the phase-change heat storage device 7, and transfers heat to the phase-change heat storage medium in the pipe row of the phase-change heat storage device 7. When the temperature of the heat storage medium in the single-tank heat storage device 2 is When it is greater than the melting point of the phase change heat storage medium in the tubes and rows of the phase change heat storage device 7, the phase change heat storage medium melts to store the phase change latent heat, and at the same time the temperature of the heat storage medium in the single tank heat storage device 2 rises. At this time, the flow direction of the heat storage medium in the tank is shown in Figure 2. Under the action of the buoyancy force, the heat storage medium flows upwards, pushing the upper cold fluid to flow through the heat release plate along the top of the single tank heat accumulator 2 The annular channel where the tube heat exchanger 3 is located pushes the cold fluid to move down along the annular channel, and absorbs the heat provided by the heat storage coil heat exchanger 10 at the bottom of the single-tank heat accumulator 2 until it is stored in the entire heat accumulator The temperature of the heat medium rises to complete the heat storage process.
释热过程，来自能量利用装置5的低温介质由放热介质入口6进入放热盘管换热器3，从单罐蓄热器2内的蓄热介质吸收热量后温度升高，升温后的放热介质从放热介质出口4返回到能量利用装置5完成释热；放热过程中，单罐蓄热器2内部流体流动方向如图3所示。放热盘管换热器3周围蓄热介质温度降低，降温后的蓄热介质沿隔热板9和单罐蓄热器2罐体之间的环形空间向下流动，推动下部热流体沿相变蓄热装置7向上流动，从单罐蓄热器2顶部流过放热盘管换热器3所在环形通道，当单罐蓄热器2内蓄热介质温度降低于到相变蓄热管7中管排管内的相变蓄热介质熔点时，相变蓄热装置7内相变潜热被释放出来，同时单罐蓄热器2内蓄热介质温度进一步下降，直至单罐蓄热器2内的储存热量被完全释放。During the heat release process, the low-temperature medium from the energy utilization device 5 enters the heat release coil heat exchanger 3 through the heat release medium inlet 6, and the temperature rises after absorbing heat from the heat storage medium in the single-tank heat accumulator 2, and the temperature rises The heat release medium returns from the heat release medium outlet 4 to the energy utilization device 5 to complete heat release; during the heat release process, the flow direction of the fluid inside the single-tank heat accumulator 2 is shown in Figure 3 .
