【摘要】：隨著改革開放的深入，近年來我國國民經(jīng)濟快速發(fā)展，我國大型公共建筑廣泛采用集中中央空調(diào)系統(tǒng)，然而中央空調(diào)系統(tǒng)已成為建筑的耗能大戶，在整個建筑能耗中空調(diào)系統(tǒng)能耗就占到60~70%，當今中央空調(diào)設(shè)計師應(yīng)對大型公共建筑中央空調(diào)系統(tǒng)的綜合冷熱源方案，風系統(tǒng)節(jié)能分析，水系統(tǒng)節(jié)能分析進行一定的研究，對于大型公共建筑的中央空調(diào)系統(tǒng)設(shè)計節(jié)能具有一個明確的思路與方法，從而得到在不同情況下對于空調(diào)設(shè)計方案的最佳選用，使得中央空調(diào)設(shè)計人員能夠快速并且清晰的從眾多方案中選擇一個最優(yōu)方案，達到省時并且節(jié)能的一個效果，這也是在設(shè)計師開始的方案設(shè)計階段的主要任務(wù)，因此空調(diào)系統(tǒng)方案的選擇和評價已經(jīng)成為空調(diào)系統(tǒng)設(shè)計過程中的一個重要環(huán)節(jié)。 本文以西安市旭景商住公寓樓為例，針對商住這種具有代表性的公共建筑進行了研究論述，針對設(shè)計對象的具體條件，對空調(diào)冷熱源方案選擇的評價方法和思路以及風系統(tǒng)與水系統(tǒng)的選用節(jié)能方案進行了分析，并首先利用DeST-c軟件對目標建筑全年動態(tài)空調(diào)負荷進行了計算分析，然后根據(jù)設(shè)計對象的地理位置、周圍環(huán)境及空調(diào)負荷的特點，確定了七種商住兩用公寓樓的典型的冷熱源設(shè)計方案，，并且對商場空調(diào)風系統(tǒng)與水系統(tǒng)做了方案節(jié)能分析對比，確定合理的風系統(tǒng)與水系統(tǒng)方案。結(jié)合西安市目前的能源結(jié)構(gòu)、環(huán)境狀況及工程本身的特點計算并比較了各方案的(商場冬夏空調(diào)、公寓住宅冬季供熱)的初投資、年經(jīng)營費用、風系統(tǒng)節(jié)能率及水系統(tǒng)節(jié)能費用，污染排放量等多個技術(shù)經(jīng)濟指標，簡單論述了商住兩用公共建筑的應(yīng)該采取的冷熱源方案、風系統(tǒng)、水系統(tǒng)所采用的節(jié)能措施。從而得出結(jié)論：在本課題研究的工程中，公寓商場電制冷+市政熱網(wǎng)（熱水換熱）評價最優(yōu)；在污水豐富，距離污水廠較近的地區(qū)當符合一定的條件時可優(yōu)先使用污水源水源熱泵；在地下土壤符合一定條件的地區(qū)，可優(yōu)先選用地源熱泵；在電力缺乏、燃氣燃油比較充足的情況下可選用常規(guī)冷水機組+直燃機,在靈活性要求較高時，可選用燃氣直燃溴化鋰冷、溫水機組或燃氣熱水機組。
[Abstract]:With the deepening of reform and opening up, China's national economy has developed rapidly in recent years. The central air-conditioning system is widely used in large public buildings in China. However, the central air conditioning system has become a major energy user of buildings. In the whole building energy consumption, the energy consumption of air conditioning system accounts for 6070. Nowadays, central air conditioning designers should do some research on the comprehensive cold and heat source scheme of central air conditioning system of large public buildings, energy saving analysis of air system and energy saving analysis of water system. There is a clear idea and method for the design energy saving of central air-conditioning system in large public buildings, so as to get the best choice of air conditioning design scheme under different circumstances. So that central air conditioning designers can quickly and clearly choose an optimal solution from a number of options, achieving a time-saving and energy-saving effect, which is also the main task in the design phase begun by the designer. Therefore, the selection and evaluation of air conditioning system has become an important step in the design process of air conditioning system. Taking Xujing commercial and residential apartment building in Xi'an as an example, this paper studies and discusses the representative public building of commercial and residential buildings, and aims at the specific conditions of the design object. This paper analyzes the evaluation method and train of thought of the scheme selection of air conditioning and heat source, and the energy saving scheme of air system and water system. At first, the dynamic air conditioning load of the target building is calculated and analyzed by using DeST-c software. Then according to the geographical location of the design object, the surrounding environment and the characteristics of the air conditioning load, the typical cold and heat source design schemes of seven commercial and residential apartment buildings are determined, and the energy saving schemes of the air conditioning system and the water system of the shopping mall are analyzed and compared. Determine a reasonable scheme for wind and water systems. Combined with the current energy structure, environmental conditions and the characteristics of the project in Xi'an City, the initial investment and annual operating cost of various schemes (air conditioning in shopping malls in winter and air conditioning in apartment buildings in winter) were calculated and compared. The energy saving rate of wind system, energy saving cost of water system, pollution discharge amount and other technical and economic indexes are briefly discussed. The energy saving measures adopted by cold and heat source scheme, wind system and water system for commercial and residential public buildings are briefly discussed. The conclusions are as follows: in the project studied in this paper, the evaluation of electric refrigeration municipal heating network (hot water heat transfer) in apartment mall is the best, and the sewage is abundant, Sewage source heat pumps may be given priority when they meet certain conditions in areas closer to the sewage treatment works; ground source heat pumps may be preferred in areas where underground soil meets certain conditions; and in the absence of electricity, The direct gas turbine of conventional chillers can be used under the condition of sufficient gas fuel. When the flexibility requirement is high, the direct combustion lithium bromide cooling, warm water unit or gas hot water unit can be selected.
