本文研究利用蒸汽喷射式热泵供热系统替代常规热力系统。减少蒸汽在减压过程中的有效能损失,回收蒸汽冷凝水系统排出的余热,使其二次蒸发汽升高能量品位后,再供生产使用。提高以蒸汽做为载热体的热能在转换、传递和利用过程中的技术水平,使能量得到充分的利用。其节能效果显著。 This paper studies the use of steam injection heat pump heating system to replace the conventional thermal system. Reduce the effective loss of steam in the decompression process, recover the residual heat from the steam condensate system, make the secondary steam to raise the energy level, and then supply it for production. Increase the steam as the heat transfer medium in the conversion, transmission and utilization of the technical level, so that energy is fully utilized. Its energy-saving effect is remarkable.
