摘要
建立了电厂循环水水源热泵数学模型,分析了凝汽器温度对热泵蒸发温度和制热系数等主要参数的影响,经过计算得到了热泵供热优于抽汽供热的临界参数。实际算例表明,当凝汽器温度高于33.65℃时,热泵供热比抽汽供热更为经济。
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 ℃.
