摘要本文建立了一个预测热泵辅助蓄热式太阳能蒸馏器能量性能的数值模型，该蒸馏器采用石蜡和水合盐等相变储热材料。数值模型是基于能量和质量平衡。这场演出是在哈萨克斯坦的Fort Sherchenko镇模拟的。比较了常规太阳能蒸馏器和热泵辅助回热式太阳能蒸馏器的性能。此外，两种不同的相变材料对热泵辅助回热式太阳能蒸馏器的热性能的影响进行了描述。数值模拟结果表明，热泵辅助蓄热式太阳能蒸馏器是更节能，并产生更好的生产率时，与传统的简单的太阳能蒸馏器。水合物盐相变储热材料的使用被认为是一个很好的选择，以提高热泵辅助回热太阳能蒸馏器的性能。
ABSTRACT A numerical model has been proposed in this research work for predicting the energy performance of a heat pump assisted regenerative solar still using phase change heat storage materials such as paraffin wax and hydrate salt. The numerical model is based on energy and mass balance. The performance was simulated for Fort Sherchenko town in Kazakhstan. The performance comparison between the conventional solar still and heat pump assisted regenerative solar still with and without phase change materials are presented. Moreover, the influence of two different phase change materials on thermal performance of a heat pump assisted regenerative solar still are described. The numerical simulation results showed that heat pump assisted regenerative solar still is more energy efficient and produces better productivity when compared to the conventional simple solar still. The use of hydrate salt phase change heat storage material was found to be a good option for enhancing the performance of a heat pump assisted regenerative solar still.
