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。
The mathematical model of circulating water source heat pump in power plant was established. The influence of condenser temperature on the main parameters of heat pump evaporation temperature and heating coefficient was analyzed. The critical parameters of heat pump heating over extraction heat supply were calculated. The actual example shows that when the condenser temperature is higher than 33.65 ℃, heat pump heating is more economical than extraction steam supply.
