Feasibility analysis of circulating water-source heat pump heating system in power plant

Establishes a mathematical model, analyses the effect of the temperature of condenser on the main parameters such as evaporator temperature and COP. Through calculation, obtains the critical parameters when heat pump heating is superior to extraction steam heating. The calculation result of an example shows that heat pump heating is more economical than extraction steam heating when the temperature of the condenser is above 33.65 ℃.
