摘　　要：针对海水源热泵应用中存在的海水直接进入机组的腐蚀及冬季海水温度过低直接进入热泵机组发生冻结的问题,该文提出将抛管式换热器应用于海水源热泵系统中,对系统进行简要介绍,建立确定换热器结构的数学模型。结合典型工程实例,对采用抛管式换热器、采用中间换热器与直接式海水源热泵系统3种方案进行经济性和环保效益的比较,得出采用抛管式换热器的海水源热泵系统在经济效益及环保效益方面均优于其他2种方案。Aiming at the corrosion issue due to the seawater directly goes in and the freeze issue because of the low temperature of seawater in winter about the application of seawater-source heat pump system （ SWHP）, this paper proposed to utilize the east heat exchanger （CHE） in the system of SWHP to overcome the issues above. A brief introduction of this system is given, supported by a mathematical model to determine the structure of CHE. Based on a typical engineering project, the conclusion is made that the SWHP with CHE is better than the other two schemes, intermediate heat exchanger and direct seawater source systems, in the perspectives of economic and environmental benefits.
