摘要(Abstract)：

分布式能源电站中存在总量较大、种类多样的低温余热,这部分热量的利用是提高分布式能源电站热效率、节约能耗的重要手段。低温余热利用技术分为同级利用和升级利用,同级利用主要是向能级相近的用户供热,而升级利用主要有热泵/制冷技术、热管、变热器、余热发电技术、热声装置等技术手段。在综合利用方面还有将各个不同能级热源和设备综合利用的DH(低温余热区域供暖)系统,将热能资源进行汇总和分配是余热利用技术的主要研究方向。
There are plenty of and various low-temperature waster heat in distributed energy power stations,the utilization of which helps improve thermal efficiency and save energy consumption. Low-temperature waste heat utilization technology comprises same-level utilization and upgraded utilization. The same-level utilization mainly supplies heat to users with similar energy levels while the upgrade utilization mainly includes heat pump/refrigeration technology, heat pipe, heat exchanger, waste heat power generation technology, and thermoacoustic device. In terms of comprehensive utilization, there is also a low-temperature waste heat DH(district heating) system that comprehensively utilizes different energy levels of heat sources and various equipment. The gathering and allocation of heat resources are major research interests of waste heat utilization technology.
