摘要

海水源热泵区域供热供冷系统作为一项可再生能源利用技术，目前尚缺乏有关该系统实际应用方面的研究。作者对黄海北部某海水源热泵区域供热供冷系统进行了实地调研与测试，获得了该系统运行方面的大量第一手数据，经计算得到：2013年冬季极端海水温度期间，所测试热泵机组的实际平均制热性能系数为2.43，相应工况下的系统平均制热性能系数为1.86；2011-2012年供暖季机组和系统的平均制热性能系数分别为2.99和2.30；夏季“免费”供冷（热泵机组不开启）测试期间，系统的平均制冷性能系数为3.35。文章进一步对夏季“免费”供冷期间系统制冷性能系数不高的原因进行了分析。分析结果表明，由于用户的风机盘管未按实际冷水温度选择，致使实际运行时冷水供、回水温差仅有1 ℃，从而导致水泵运行能耗过高。

Abstract

Seawater source heat pump system (SWHP) is a renewable energy utilization system. But it is lack of practical application study about the system up to now. In this study

a SWHP system in coastal area of the northern Yellow Sea was measured. The winter measurement results showed that the average heating COP of a heat pump unit and the whole system were 2.43 and 1.86 respectively during the measurement period while the corresponding COP were 2.99 and 2.30 respectively during the whole heating season. The summer measurement results showed that the average cooling COP of the system was 3.35 during the measurement period．This paper further analyzed the major cause of the low free cooling system COP

and it is that the fan coil units are not selected by actual seawater temperature

which leads to the low supply and return water temperature difference (only 1 ℃) and high circulating pump energy consumption.
