摘要
探讨了热电热泵相变蓄热装置的工作原理。对热电热泵相变蓄热装置蓄热、放热工况下相变材料(石蜡)温度、状态的变化及制热性能系数进行了分析。实验条件下,相变材料的相变过程明显,蓄放热效果理想。蓄热阶段,余热热源温度为32℃、工作电压为8V时,制热性能系数达到2.2;放热阶段,被加热冷风温度为25℃、工作电压为4V时,制热性能系数达到5.6。
The working principle of thermoelectric heat pump phase change heat storage device is introduced. The temperature, state variation and heating performance coefficient of phase change material （paraffin） under heat storage and release working conditions are analyzed. The phase change process of the material is obvious with ideal heat storage and release effect under the experimental condition. The heating performance coefficient is 2.2 when the temperature of residual heat source is 32 ℃ and the working voltage is 8 V in the heat storage stage. The heating performance coefficient is 5.6 when the temperature of heated cold air is 25 ℃ and the working voltage is 4 V in the heat release stage.
