Analysis of Key Factors in the Application of Ground Source Heat Pump in Buildings Based on Cost Control

随着地源热泵技术的日趋成熟和广泛应用,如何有效控制地源热泵系统初始投资与运行成本已成为地源热泵建筑应用项目成功推广的关键。对于具备自然地理条件的应用项目而言,其成本控制主要与浅层地热能资源禀赋、浅层地热能建筑应用规划、地源热泵系统设计三大关键因素直接相关。本文从分析浅层地热能的特点出发,立足国家“双碳”战略需要,运用系统工程的思维,对影响地源热泵建筑应用项目成本控制的三大关键因素进行了分析论证,并提出了系统的解决路径。

The application of ground source heat pump in buildings is a complex system engineering.With the increasing maturity and widespread application of ground source heat pump technology,how to effectively control the initial investment and operating costs of ground source heat pump systems has become the key to the successful promotion of ground source heat pump building application projects.For shallow geothermal energy building application projects with natural geographical conditions,cost control is mainly related to three key factors:whether they have the advantage of shallow geothermal energy resource endowment,whether the planning of shallow geothermal energy building application is reasonable,and the energy efficiency of ground source heat pump system design.In the application of ground source heat pump in buildings,the thinking of system engineering must be applied,and the cost control concept must be integrated throughout the entire process of building application.The initial investment cost,operating cost,and life cycle cost of the ground source heat pump system must be comprehensively and reasonably controlled from the aspects of system technical feasibility,economic rationality,and operational stability and sustainability,in order to promote the promotion of ground source heat pump,a shallow geothermal energy building application technology.Starting from the analysis of the characteristics of shallow geothermal energy and based on the needs of the national"dual carbon"strategy,this article analyzes and demonstrates the three key factors that affect the cost control of ground source heat pump building application projects,and proposes a systematic solution path,in response to the misconception that ground source heat pumps are"environmentally friendly and not energy-saving"that many projects havebroughtto investors and consumersdue topoorcost control.
