【摘要】 本文从经济、环境两个方面对海水源热泵空调技术在我国的应用进行了分析。首先对该地区全年海水和污水温度分布情况进行分析,结果表明水温条件满足热泵运行条件。结合一个典型工程,对该项目方案设计进行了介绍,按照技术经济学的方法,对传统系统和海水源热泵空调系统进行了经济性对比。结果表明只有在一定的优惠政策下,海水源热泵空调系统经济性才可行。最后通过对海水取排水区域温度场的数值模拟表明在在适度规模和合理设计取排水口位置条件下,海水的温升满足国家海水排放标准。更多还原

【Abstract】 This paper presents a study on economics and environmental impacts for seawater source heat pumps to provide district cooling and heating in Dalian. Through an all–year investigation of the temperature of seawater and sewage,it shows that the conditions are favorable to using water-source heat pump to produce thermal energy. First,combined with a typical project the scheme design of seawater air-conditioning system (SWAC) is analyzed. Then,based on the basic principle of technical economic,it is shown that the SWAC is economically feasible under favorable policy. Finally,the numerical simulations of seawater temperature field are performed by using a two-dimensional depth-average plane equation model to evaluate environmental impacts. According to the simulation results,it can be seen that the temperature elevation is far less than the standard of Grade Ⅰof Quality Standard for State Oceanic Water.更多还原
