Discussion of Heating System Using Heat Pumps with Circulating Water in Power Plant as Heat Source

摘要

There is a lot of low-grade heat energy in circulating cooling water in power plants,and the heat pump has the ability to elevate energy from low-grade to high-grade.The text makes the feasibility analysis about using heat pump technology to recycle the waste heat of circulating water in power plant and makes the comparison with conventional thermal power plant.The results show that it can not only supply the problem of supplying heating for adjacent users,but also can decrease the operation cost of circulating water pumps and increase the comprehensive energy efficiency of power plant,at the same time,it also can decrease the discharge of urban waste heat,reduce the greenhouse effect,protect environmental and save energy.
