摘要
由于土壤源、湖水源热泵的应用受到地理条件、初投资等因素的制约，某些地区更适宜采用土壤源-湖水源的混合式热泵系统。以某工程应用为例，分别从性能系数、初投资及运行费用3个方面分析证明了采用混合式热泵系统的可行性。结果表明，混合式热泵系统的初投资虽然较大，但通过节约运行费用，在较短年限内可收回增加的成本，并且可以减少废水废气的排放。因此，在合适的地区可以推广使用土壤源-湖水源的混合式热泵系统。
While the application of ground source and lake source heat pump is restricted by some factors such as geographical conditions, initial investment factors and so on, some areas are more appropriate to using ground source plus lake source hybrid heat pump system. As an example of a project, the feasibility of using hybrid heat pump system from three factors of coefficient of performance （COP）, initial investment and operating costs is analyzed and proved, and the conclusion is obtained that though the initial investment of a hybrid heat pump system is larger, the increased costs can be recovered in several years through annual savings of operating costs, and liquid waste and emissions can be sharply reduced annually. So it shows that hybrid heat pump system may be practicable in right areas.
