【摘要】：建筑能耗在我國總能耗中位列第三，約占到了1/3，空調(diào)系統(tǒng)能耗占建筑能耗的40%~60%。商業(yè)綜合體建筑又是典型的高能耗建筑，目前該類型建筑在各一線城市甚至二三線城市的興建活動又異�；钴S，因此，為了使我國的建筑能耗早日達(dá)到發(fā)達(dá)國家的節(jié)能標(biāo)準(zhǔn)，商業(yè)綜合體建筑的空調(diào)能耗的節(jié)能減排技術(shù)研究勢在必行。本文以夏熱冬冷地區(qū)商業(yè)綜合體建筑為研究對象，重點(diǎn)研究空調(diào)系統(tǒng)的能耗，研究一些節(jié)能空調(diào)技術(shù)在該類型建筑中應(yīng)用的節(jié)能效果。 首先，按氣候特征將夏熱冬冷地區(qū)分為五個區(qū)域，每個區(qū)域選一個代表城市進(jìn)行調(diào)查研究。每個區(qū)調(diào)查幾個已建成的典型的商業(yè)綜合體建筑，對建筑構(gòu)成能耗、空調(diào)系統(tǒng)能耗情況、設(shè)備選型及使用效率、室內(nèi)舒適度情況進(jìn)行調(diào)查分析。 其次，選擇一個代表城市的商業(yè)綜合體建筑，筆者選擇武漢市的某商業(yè)綜合體建筑進(jìn)行能耗模擬，，模擬軟件選擇DeST，將模擬結(jié)果與實(shí)際情況進(jìn)行對比分析，在此基礎(chǔ)上將調(diào)查到的空調(diào)系統(tǒng)應(yīng)用于該模型中，輸出相關(guān)能耗數(shù)據(jù)，并進(jìn)行有關(guān)分析；為了分析整個夏熱冬冷地區(qū)的空調(diào)系統(tǒng)能耗，需將該模型應(yīng)用于其他幾個區(qū)的代表城市，并進(jìn)行相同的模擬分析。 再次，針對模擬的結(jié)果和調(diào)查數(shù)據(jù)，提出集中冷熱源的思想，以減少設(shè)備初投資費(fèi)用，提高設(shè)備的利用率，并針對這種技術(shù)提出可能出現(xiàn)的問題，尋找解決的方法。 最后，尋找空調(diào)運(yùn)行系統(tǒng)可以節(jié)能的技術(shù)，例如將水系統(tǒng)大溫差運(yùn)行、變風(fēng)量空調(diào)系統(tǒng)、排風(fēng)熱回收技術(shù)、過渡季冷卻塔免費(fèi)供冷技術(shù)應(yīng)用于商業(yè)綜合體建筑中，通過模擬計(jì)算，對比調(diào)查中常用的空調(diào)系統(tǒng)能耗值，給出對比結(jié)果分析所選用的空調(diào)系統(tǒng)節(jié)能技術(shù)的可行性.
[Abstract]:Building energy consumption ranks third in the total energy consumption in China, accounting for about one third of the total energy consumption, and the energy consumption of air conditioning system accounts for 40% of the building energy consumption. Commercial complex buildings are also typical high-energy consuming buildings. At present, the construction activities of this type of buildings in first-tier cities and even second-third-tier cities are extremely active. Therefore, in order to make our country's building energy consumption meet the energy conservation standards of developed countries as soon as possible, It is imperative to study the energy saving and emission reduction technology of air conditioning in commercial complex buildings. This paper takes commercial complex buildings in hot summer and cold winter area as the research object, and focuses on the energy consumption of air conditioning system. The energy-saving effect of some energy-saving air-conditioning technology applied in this type of building is studied. First of all, the hot summer and cold winter regions are divided into five regions according to the climatic characteristics. Each region selects a representative city for investigation and study. Each district investigates several typical commercial complex buildings that have been built, which constitute energy consumption for the buildings. Air-conditioning system energy consumption, equipment selection and use efficiency, indoor comfort is investigated and analyzed. Secondly, the author chooses a commercial complex building which represents the city. The author chooses a commercial complex building in Wuhan to simulate energy consumption, and the simulation software chooses set. The simulation results are compared with the actual situation. On this basis, the investigated air conditioning system is applied to the model, the relevant energy consumption data are outputted and analyzed, in order to analyze the energy consumption of the air conditioning system in the whole hot summer and cold winter area, The model needs to be applied to representative cities of other districts and the same simulation analysis is carried out. Thirdly, according to the results of simulation and investigation data, the idea of concentrating heat and cold source is put forward to reduce the initial investment cost of equipment and improve the utilization rate of equipment. Finally, looking for technologies that can save energy in air conditioning systems, such as large temperature difference operation of water systems, variable air volume air conditioning systems, exhaust heat recovery technology, free cooling technology for cooling towers in the transitional season, and application in commercial complex buildings. Through simulation and calculation, the energy consumption of air conditioning system commonly used in investigation is compared, and the feasibility of the energy saving technology of air conditioning system selected for comparison analysis is given.
