摘　　要：为比较我国不同海域海水源热泵系统适应性及能效,着重分析了海水源热泵系统在我国5个典型海水区域的系统组成及系统运行总能耗。以某沿海办公楼为依托,使用建筑能耗分析软件DEST分别模拟出在天津、大连、青岛、上海、温州等5个典型沿海区域该建筑的全年空调负荷,采用温频法计算建筑全年通风空调能耗,结合不同海水源热泵取水形式在一定输送距离所需输送能耗得到各运行工况下海水源热泵系统能效参数,分析对比得出海水源热泵系统的COP值在空调制冷工况下比空气源热泵高出30%以上,空调供热工况比燃煤锅炉高23%以上,为我国不同区域海水源热泵系统的使用提供一定的理论依据。To compare the different waters of the sea water source heat pump system adaptability and energy efficiency, the paper focuses on analysis of sea water source heat pump system in China five regions typical seawater system components and the system is running total energy consumption. Taking a coastal building as the basis, the use of building energy analysis software DEST were simulated in Tianjin, Dalian, Qingdao, Shanghai, Wenzhou these five typical coastal areas of the building＇ s annual cooling load, Using temperature-frequency method to calculate the annual construction ventilation and air conditioning energy consumption, a combination of different forms of sea water source heat pump water at a certain distance transport transportation energy consumption required to obtain the operating conditions of the sea water source heat pump system efficiency parameters, analysis and comparison drawn sea water heat pump system COP values than in air conditioning and refrigeration conditions air source heat pump more than 30%, air conditioning heating mode is 23% higher than coal-fired boiler over different areas of the sea for our water source heat pump system is used to provide a theoretical basis.
