摘要(Abstract):

用潜热能储存系统回收空调系统排放的热量 ,可生产温热生活用水。既可降低加热生活用水的基本能量消耗 ,又可减小空调系统排放热量引起的环境增温。为了开发空调冷凝热的储存、回收利用 ,本文研究了石蜡基蓄热材料及其改性材料降低相变储热温度。通过实验探讨了石蜡的热物理性能及石蜡的凝固与熔解曲线和加入食品添加剂后熔点和凝固点的变化及其热稳定性
Latent heat thermal energy storage systems are used to recover the rejected heat from air conditioning systems,which can be used to produce low-temperature living heat water.It decreases not only the consumption of primary energy for heating the living water but also the calefaction to the surroundings due to the rejection of heat from air conditioning systems. Technical grade paraffin wax as phase change material for the thermal energy reclamation of the rejected heat from air condition systems has been discussed in this paper,in order to develop a paraffin wax based phase change material compliant for the heat storage.The thermal properties of technical grade paraffin wax and the mixtures of paraffin wax with strawberry essence or lauric acid are investigated and discussed,including volume expansion during the phase change process,the freezing point and thermal stability.
