大连某海水源热泵区域供热系统的实测分析
A seawater source heat pump district heating system analysis of the actual measurement in Dalian
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%。

Abstract：
According to the measured data, the paper analyzes the heat pump units and the whole efficiency of the heat pump district heating system. The results show that sea water source heat pump units in the case of low temperature of seawater in winter can still running, but the heating coefficient of performance of the unit is low (about 2.43), the heating coefficient of performance of the system as a whole are even more low (average 1.86). Further analysis of the influence factors of conditioning unit. Simulation calculation, found that if choose good performance of heat pump units on the market, the heating coefficient of performance will increase 34.2%, overall system efficiency can increase about 24.2%.
