【摘要】 我国南方地区的地表水资源丰富,其中蕴藏着丰富的低位热能,适合于建造地表水源热泵系统。2004年,在湖南省湘潭市城市中心区建造了利用湖水的试验性的开式水源热泵区域供冷供热系统。建造该系统前,对运行时湖水水温分布进行了模拟分析。对系统投入运行以来每日的湖水进水温度进行了监测,对湖水源热泵和风冷热泵的能效比进行了测试。测试结果表明,该湖水源热泵的能效比及运行稳定性均优于风冷热泵。更多还原

【Abstract】 Rich surface water resources in south China can be utilized as heat source - sink in heat pump systems. A district heating and cooling system that utilizes lake water as heat source - sink of heat pumps has been constructed in Xiangtan, a city in Hunan province in south China. To predict the impacts of thermal discharge on entering water temperature and on the ecological environment of lake, water temperature variations along the water flowing direction during continuous operation were simulated before the construction. Initial study and field test results revealed that the district heating and cooling system could offer advantages over distributed air - source heat pump units, such as higher energy efficiency and improved reliability.更多还原
