摘要

以300MW机组为例

分析计算了火电厂抽汽供热与循环水-水源热泵供热2种方式的特点和能耗。结果表明

当水源热泵系统的能效比(COP)大于5.03时

循环水-水源热泵供热方式的节能效果较好。目前水源热泵在实际运行时COP为4.5~5.5

其供热能耗与抽汽供热相当。

Abstract

Taking a 300 MW unit as the example

the characteristics and energy consumption of two heating approaches

extraction steam heating and circulating water-water source heat pump(CW-WSHP)heating

were investigated.The results show that

when the coefficient of performance(COP)of the water source heat pump system is larger than 5.03

the CW-WSHP heating method has better energy saving effect than the extraction steam heating method.Due to limitation of the technology

the actual COPof the current water source heat pump is about 4.5to 5.5. Therefore

the energy consumption of the CW-WSHP heating method is basically equivalent to that of the extraction steam heating method.
