By analyzing the way of circulating water-water source heat pump heating and direct pumping heat supply, the water source heat pump recovers low-grade power plant circulating water waste heat, which has significant energy saving potential. The water source heat pump technology is used to recover the residual heat of circulating water in low-temperature power plants, realizing the conversion of energy from low grade to high grade, in line with the principle of energy cascade utilization. The critical parameters of water source heat pump heating are better than conventional heating by calculation and analysis. The actual example shows that when the pumping temperature reaches 188 °C, the water source heat pump is more energy efficient than the pumping heat.
