| 摘 要： | 针对一种主动式热电热泵相变蓄热装置,在不同工作电压和不同热源温度下测试其蓄热和放热性能。实验结果表明,在不同工作电压和不同热源温度时,该装置的蓄/放热时间以及蓄/放热效率有很大差异。在工作电压较高,余热热源温度较高的情况下,该装置蓄热所需时间较短;此时继续增加工作电压会导致半导体芯片冷热端温差变大而降低该装置的制热系数。对比被动式相变蓄热装置,该装置最大的优越性在于工作电压的可调性,在合理的范围内调整工作电压大小,可以保证其较高的蓄/放热性能,同时克服了被动式相变蓄热装置在低温余热回收过程中无法改善热能供需双方在时间、地点和强度上不匹配性的缺点。

| Abstract: | In this paper,the heat storage and release properties of an active phase-change thermal storage device have been tested under different working voltage and exhaust heat temperature.The experimental results show that: different working voltage and exhaust heat temperature make great difference on the time and efficiency of thermal storage/release.Under higher voltage and exhaust heat temperature,the time that the device needs to store heat is short.The increased working voltage can enlarge the temperature di... |
