【摘要】：能源是推进社会经济发展、增强人类拓展力的源动力，节能与环保成为当今世界的主题。在此形势下，许多发达国家通过完善法律框架来力推节能政策，并以能源效率作为能源政策基本工具。能耗高与能源利用效率低使我国能源形势更加严峻，日益突出的能源与环境问题已成为制约我国经济可持续发展的两大问题。节能环保已成为我国社会可持续发展的重大举措。本文以北京某规划区域的供暖空调及生活热水方案为例，对太阳能辅助土壤源热泵系统加冰蓄冷系统进行了详细研究，并对系统节能性、经济性进行了分析，为相似工程实践提供参考。本文的工作主要包括以下四个方面。首先介绍了所研究的工程的基本情况，分析了项目所在地的气候及地质条件，对拟建建筑的热负荷、冷负荷、生活热水负荷进行了分析，，为后面的研究提供基础材料。其次，针对本文所研究的拟建工程的实际情况及当地的能源资源情况，设计出一套结合了土壤源热泵、太阳能利用、冰蓄冷技术的综合能源系统。对设计的太阳能-土壤源热泵综合应用系统的原理进行了说明，并对系统的热水供系统流程、供热流程、空调流程分别进行了分析。对系统进行了设计，对主要设备的选择进行了分析与计算。然后，对太阳能-土壤源热泵综合应用系统的节能效果进行了分析。对系统主要设备的逐时能耗和全年能耗分别进行了分析，并与常规系统进行了对比分析，结果表明，与采用电加热供热水和集中供热相比，设计的综合应用系统有较好的节能效果。最后，对太阳能-土壤源热泵综合应用系统的经济性进行了分析。分别从系统的初投资、回收期的角度研究了本文设计的系统的经济性，并计算了系统的设备投资经济指标及供冷运行经济指标。
[Abstract]:Energy is the driving force to promote social and economic development and enhance human expansion. Energy conservation and environmental protection have become the theme of the world today.Under this situation, many developed countries push forward the energy saving policy by perfecting the legal framework, and take energy efficiency as the basic tool of energy policy.High energy consumption and low energy use efficiency make the energy situation more severe in China. The increasingly prominent energy and environment problems have become two major problems restricting the sustainable development of our economy.Energy saving and environmental protection has become a major measure of sustainable development of our society.Taking the scheme of heating, air conditioning and domestic hot water in a planned area of Beijing as an example, this paper makes a detailed study on the ice storage system of the solar assisted ground source heat pump system, and analyzes the energy saving and economy of the system.It provides reference for similar engineering practice.The work of this paper mainly includes the following four aspects.This paper first introduces the basic situation of the studied project, analyzes the climate and geological conditions of the project location, analyzes the heat load, cooling load and domestic hot water load of the proposed building, and provides the basic materials for the later research.Secondly, according to the actual situation of the proposed project and the local energy resources, a comprehensive energy system which combines the ground-source heat pump, solar energy utilization and ice storage technology is designed.The principle of the integrated application system of solar-ground source heat pump is explained, and the flow of hot water supply system, heating flow and air conditioning system are analyzed respectively.The system is designed, and the selection of main equipment is analyzed and calculated.Then, the energy-saving effect of the integrated application system of solar-ground source heat pump is analyzed.The hourly energy consumption and the annual energy consumption of the main equipment of the system are analyzed, and compared with the conventional system, the results show that compared with the electric heating for hot water supply and central heating,The designed integrated application system has better energy saving effect.Finally, the economy of the integrated application system of solar-ground source heat pump is analyzed.The economy of the system designed in this paper is studied from the angle of the initial investment and the payback period of the system, and the economic indexes of the equipment investment and the operation of the cooling system are calculated.
