【摘要】:在能源匱乏和環(huán)保意識增強的今天,大力發(fā)展可再生能源建筑是解決問題的重要策略。所謂可再生能源,通常是指不污染環(huán)境,取之不盡、用之不竭,并且可以循環(huán)再利用的能源,主要包括太陽能、地熱能、風能、水能、生物能和潮汐能等,我們也可稱它們?yōu)榫G色能源。現(xiàn)代的智能建筑要不斷的發(fā)展,跟上時代的步伐,必須和綠色能源有機地結合。在今天,促進建筑向綠色化、節(jié)能型、智能化的方向發(fā)展,是實現(xiàn)建筑業(yè)可持續(xù)發(fā)展的一個總的趨勢。當前,零能耗建筑成為可再生能源建筑技術應用的未來趨勢。為了研究如何在綠色能源樓中實現(xiàn)零能耗,本文針對綠色能源樓中的能源種類、設計建筑設備自動控制系統(tǒng)和能源調配等幾方面進行了研究。主要工作如下:(1)分析研究綠色能源樓中所涉及的綠色能源的種類。綠色能源樓中的綠色能源主要可分為電能與熱能兩大類。電能主要由光伏發(fā)電、風力發(fā)電、微型冷熱電聯(lián)供系統(tǒng)這些綠色能源來提供。熱能主要由水源熱能、地源地熱和太陽能聚熱能系統(tǒng)等這些綠色能源來提供。(2)開發(fā)自動控制系統(tǒng)對綠色能源樓中的設備進行實時監(jiān)控管理。本系統(tǒng)是以綠色能源樓的實際需求進行研究與開發(fā)的,在系統(tǒng)軟、硬件方面做了設計。本系統(tǒng)硬件的主要的模塊包括上位機PC、中心接入機Master、路由器、控制單元DDC(Direct Digital Controller)和數(shù)據(jù)采集控制單元。該系統(tǒng)軟件前臺采用可視化編程工具Delphi6.0進行開發(fā)實現(xiàn)了系統(tǒng)監(jiān)控、通信管理、數(shù)據(jù)處理、控制命令、動態(tài)顯示等功能,后臺數(shù)據(jù)庫采用SQL數(shù)據(jù)庫。本系統(tǒng)開發(fā)了監(jiān)控程序、通信程序和控制程序,完成了硬件電路的設計,實現(xiàn)了各部分控制功能,具有較強的實用性。(3)綠色能源樓的多種能源的合理調配,實現(xiàn)各種的能源互補。通過自動控制系統(tǒng)對綠色能源樓的各種設備進行控制,可以方便的獲得各個設備的能量使用的各種狀態(tài),由此可計算出各種能量的使用量,可以詳細分析綠色能源樓的熱能與電能的使用情況。當熱能不足時可通過電能來補充;當熱能過多時,把多余熱能轉換為電能;當電能過多時存儲在蓄電池中等等。使整個綠色能源樓的設備實現(xiàn)不依靠外網(wǎng)供電,通過各種綠色能源滿足實驗樓所有能耗需求,最終實現(xiàn)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.
