热泵在热电联产中的应用

Application of Heat Pump in Combined Heat and Power

在电厂中,大量的低温余热被浪费,通过对电厂余热的回收利用可以提高热利用效率。本研究将热泵作为电厂余热的回收装置,回收利用电厂冷却循环水。首先,热泵从系统最大程度的吸收可利用热量;其次,优化系统使其在最佳真空下运行。最后,增加供暖面积使电厂利益最大化。该方案对能量和水资源的保护有一定的借鉴作用。

A great deal of low-temperature waste heat is exhausted in the power plant, and the utilization efficien-cyof waste heat can be improved by the recycling and utilization of waste heat in power plant. In this paper,theheat pumpis used as the facility for the recovery of the waste heat to recycle the circulating cooling water of thepower plant.Firstly, the heat pump absorbs the usable heat to the maximum. Secondly, the system is optimized tooperate invacuum. At last, the areas of heating is increased to achieve the maximum benefits of power station.Theresults will be good references for the energy and water source conservation.
