摘要
根据现场实测数据,分析了热泵机组及整个热泵区域供热系统的能效情况。结果表明,海水源热泵机组在冬季海水温度极低的情况下仍可运转,但机组的制热性能系数很低(约为2.43),系统整体的制热性能系数则更低(测试平均值为1.86)。进一步分析了影响机组制热性能的因素。模拟计算发现,若选择市场上性能优良的热泵机组,其制热性能系数将提升34.2%,系统整体能效可提升约24.2%。
Based on the field measurement data, analyses the energy efficiency values of the seawater source heat pump unit and the whole district heating system. The results show that the seawater source heat pump unit can still run under very low seawater temperature condition in winter, but the coefficient of heating performance （COP） of the unit is quite low （as low as 2.43） and the COP of the whole system is even lower （with an average of 1.86）. Then analyses the influencing factors on the heating performance of the heat pump unit. Simulation result shows that the heating COP of the heat pump unit can increase 34. 2%, and the heating COP of the system can increase 24.2% just by the substitution of the current seawater source heat pump unit with better performance ones in the market.
