| 摘要: |
| 为解决单一节能技术的局限性,采用相变温度为6℃的有机相变材料,结合三套管蓄能换热器,用一种蓄能换热器,与空气源、太阳能热泵组成集成系统.通过建立三套管蓄能换热器的数学模型,模拟了三套管蓄能换热器直接蒸发蓄冷动态特性,结果表明:通过与传统的冰蓄冷比较,高温相变材料蓄冷比冰蓄冷平均蒸发温度高10℃左右,高温相变材料蓄冷的COP值比冰蓄冷提高了近25%,相同制冷能力下相变蓄冷功耗节能率达36%,取得了良好的节能效果. |

| Abstract: |
| Using phase change material of phase-change temperature 6 ℃,a triple-sleeve energy storage exchanger was proposed,in which the exchanger,air source and solar heat pump were integrated.Cool storage characteristics of the triple-sleeve energy storage exchangers with direct evaporative was simulated by a mathematical model.Comparing with the traditional ice storage,the average evaporation temperature of high-temperature phase change cold storage was 10 ℃ higher than that of the ice storage.The COP values of high-temperature phase change cold storage were increased by nearly 25 percent than that of the ice-storage.The power saving rate of the phase change cold storage achieved 36% at the same cooling capacity. |
