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。
In view of seawater source heat pump application of seawater directly into the unit corrosion and the winter sea water temperature is too low directly into the heat pump unit freezing problem, this paper proposed the use of tubeless heat exchanger seawater source heat pump system, the system is briefly Introduction, the establishment of a mathematical model to determine the structure of the heat exchanger. Combined with the typical engineering examples, the economic and environmental benefits of the three schemes using the tubeless heat exchanger, the intermediate heat exchanger and the direct seawater source heat pump system are compared, and the seawater source using the tubeless heat exchanger Heat pump system in economic and environmental benefits are better than the other two kinds of programs.
