摘　　要：针对矿山法修建的排水型海底隧道存在大量渗流海水未经利用直接排放造成能源浪费的问题,提出将隧道渗流海水作为水源热泵系统冷热源为隧道附近建筑供热、供冷的利用方案。在青岛市建造了海底隧道渗流海水热泵系统示范工程,通过对制冷季运行工况的监测,分析了热泵系统在实际工程中的运行效果。实验结果表明热泵运行期间,测试房间平均温度24.5℃,室内温度可以到达设计要求。热泵系统日平均耗电量为1466.3 kW·h,其中输配系统能耗占整个系统能耗的31%,制冷季热泵机组平均能效比(EER)为5.3,系统供能效果较好。本研究为渗流海水源热泵系统的工程应用提供了数据支撑。Aiming at the problem of energy waste caused by the direct discharge of a large amount of seawater seepage without being utilized in the drainage-type undersea tunnel constructed by the mining method,it is proposed that seawater seepage from the tunnel be used as the cooling and heating source of the water-source heat pump system,which can supply heat and cold to buildings near the tunnel.A demonstration project of seepage seawater heat pump system in submarine tunnel was built in Qingdao,and the operation effect of the heat pump system in the actual project was analyzed through the monitoring of the operation condition in the cooling season.The experimental results showed that during the operation of the heat pump,the average temperature of the test room was 24.5℃,and the indoor temperature can reach the design requirements.The average daily power consumption of the heat pump system was 1466.3 kW·h,of which the energy consumption of the transmission and distribution system accounted for 31%of the energy consumption of the whole system,and the average energy efficiency ratio(EER)of the heat pump unit in the cooling season was 5.3,which made the system more effective in energy supply.This study provides data support for the engineering application of seepage seawater source heat pump system.
