【摘要】：在能源匮乏和环保意识增强的今天,大力发展可再生能源建筑是解决问题的重要策略。所谓可再生能源,通常是指不污染环境,取之不尽、用之不竭,并且可以循环再利用的能源,主要包括太阳能、地热能、风能、水能、生物能和潮汐能等,我们也可称它们为绿色能源。现代的智能建筑要不断的发展,跟上时代的步伐,必须和绿色能源有机地结合。在今天,促进建筑向绿色化、节能型、智能化的方向发展,是实现建筑业可持续发展的一个总的趋势。当前,零能耗建筑成为可再生能源建筑技术应用的未来趋势。为了研究如何在绿色能源楼中实现零能耗,本文针对绿色能源楼中的能源种类、设计建筑设备自动控制系统和能源调配等几方面进行了研究。主要工作如下:(1)分析研究绿色能源楼中所涉及的绿色能源的种类。绿色能源楼中的绿色能源主要可分为电能与热能两大类。电能主要由光伏发电、风力发电、微型冷热电联供系统这些绿色能源来提供。热能主要由水源热能、地源地热和太阳能聚热能系统等这些绿色能源来提供。(2)开发自动控制系统对绿色能源楼中的设备进行实时监控管理。本系统是以绿色能源楼的实际需求进行研究与开发的,在系统软、硬件方面做了设计。本系统硬件的主要的模块包括上位机PC、中心接入机Master、路由器、控制单元DDC(Direct Digital Controller)和数据采集控制单元。该系统软件前台采用可视化编程工具Delphi6.0进行开发实现了系统监控、通信管理、数据处理、控制命令、动态显示等功能,后台数据库采用SQL数据库。本系统开发了监控程序、通信程序和控制程序,完成了硬件电路的设计,实现了各部分控制功能,具有较强的实用性。(3)绿色能源楼的多种能源的合理调配,实现各种的能源互补。通过自动控制系统对绿色能源楼的各种设备进行控制,可以方便的获得各个设备的能量使用的各种状态,由此可计算出各种能量的使用量,可以详细分析绿色能源楼的热能与电能的使用情况。当热能不足时可通过电能来补充;当热能过多时,把多余热能转换为电能;当电能过多时存储在蓄电池中等等。使整个绿色能源楼的设备实现不依靠外网供电,通过各种绿色能源满足实验楼所有能耗需求,最终实现零能耗。
[Abstract]:In today's energy shortage and environmental protection awareness, the development of renewable energy building is an important strategy to solve the problem. The so-called renewable energy usually refers to non-polluting, inexhaustible and recyclable sources of energy, mainly solar, geothermal, wind, water, biomass and tidal energy. We can also call them green energy. Modern intelligent buildings must be combined with green energy to keep up with the pace of the times. Today, it is a general trend to realize the sustainable development of construction industry to promote the development of green, energy-saving and intelligent architecture. At present, zero-energy building becomes the future trend of renewable energy building technology application. In order to study how to achieve zero energy consumption in the green energy building, this paper studies the energy types in the green energy building, the design of building equipment automatic control system and energy allocation. The main work is as follows: 1) analyze and study the types of green energy involved in green energy buildings. The green energy in the green energy building can be divided into two categories: electric energy and heat energy. Electricity is mainly supplied by green energy such as photovoltaic power generation, wind power generation, and micro cogeneration systems. Thermal energy is mainly provided by such green energy as water source heat energy, geothermal energy source and solar energy accumulation system, etc.) automatic control system is developed to monitor and manage the equipment in green energy building in real time. The system is based on the actual demand of green energy building and is designed in software and hardware. The main hardware modules of the system include PC, MasterCard, router, DDC(Direct Digital controller and data acquisition control unit. The software foreground of the system is developed with the visual programming tool Delphi6.0. The functions of system monitoring, communication management, data processing, control command and dynamic display are realized. The background database adopts SQL database. The system has developed the monitoring program, communication program and control program, completed the design of the hardware circuit, realized the control function of each part, and has strong practicability. To achieve a variety of energy complementarities. Through the automatic control system to control all kinds of equipment in the green energy building, it is convenient to obtain the various states of the energy use of each equipment, and thus calculate the use of various kinds of energy. The use of heat and electricity in green energy buildings can be analyzed in detail. When the heat energy is insufficient, it can be replenished by electric energy; when the heat energy is excessive, the excess heat energy can be converted into electric energy; when the electric energy is too much, it can be stored in the battery and so on. The equipment of the whole green energy building does not depend on the power supply of the outside network, and all the energy consumption needs of the experimental building can be satisfied by all kinds of green energy sources, and finally the zero energy consumption can be realized.
