【摘要】:隨著我國經濟和國民生活水平的蓬勃發(fā)展,公共建筑遍地開花,而作為能耗大戶,公共建筑已成為節(jié)能的重點,通過現(xiàn)有節(jié)能技術和運行管理模式等措施可以實現(xiàn)能耗的減負,有巨大的節(jié)能潛力。 本文選取西安市某公共建筑為研究對象。首先進行實地調研,,了解該商場的能耗現(xiàn)狀,包括室內照明、設備及空調等各項能耗支出,發(fā)掘其節(jié)能空間;其次,分別在空調季、過渡季及采暖季對建筑的室內環(huán)境及空調系統(tǒng)的運行狀況進行了實時的監(jiān)測,結合理論分析測試數(shù)據,提出措施,利用能耗模擬軟件DesignBuilder與EnergyPlus進行模擬對比分析,預測措施實施后的節(jié)能效果。 通過對測試數(shù)據與能耗模擬的綜合分析,得出以下結論:①營業(yè)場內的空調系統(tǒng)平衡性較差,調節(jié)平衡后空調季共可節(jié)省15.3萬kWh電量;②商場內的平均照度和LPD均超標,在照度不變的情況下用T5替換T8燈具可節(jié)省86萬kWh電量;③兩臺冷水機組的COP分別為4.7和4.6,制冷能力已有較大的衰減,冷卻塔效率也偏低,需要維護保養(yǎng);④商場在不供給新風的情況下,兩臺1067RT的機組可以滿足制冷需要,如開啟新風需額外開啟備用的660RT螺桿機組;⑤設置排風熱回收系統(tǒng)比無新風的運行方式下多消耗64.9萬kWh電量,比開啟新風方式節(jié)約25.4萬kWh電量;⑥合理設置空調系統(tǒng)的開機時間,在空調季可節(jié)省25.6萬kWh的耗電量,約占空調系統(tǒng)總耗電量的6.6%。
[Abstract]:With the vigorous development of our economy and national living standards, public buildings are blooming everywhere, and as a large household of energy consumption, public buildings have become the focus of energy conservation. Through existing energy saving technology and operation management mode, energy consumption reduction can be realized, which has great energy saving potential. In this paper, a public building in Xi'an is selected as the research object. Firstly, the field investigation is carried out to understand the current situation of energy consumption in the shopping mall, including indoor lighting, equipment and air conditioning and other energy consumption expenditure, to explore its energy-saving space; Secondly, in the air conditioning season, transition season and heating season, the indoor environment of the building and the operation of the air conditioning system are monitored in real time. Combined with the theoretical analysis of the test data, the measures are put forward. The energy consumption simulation software DesignBuilder and EnergyPlus are used to compare and analyze the energy saving effect. Based on the comprehensive analysis of test data and energy consumption simulation, the following conclusions are drawn: the balance of air conditioning system in the business field of 1: 1 is poor, and 153,000 kWh electricity can be saved in the season after adjusting the balance; (2) the average illumination and LPD in the market exceed the standard, and the electricity consumption of 860,000 kWh can be saved by replacing T8 lamps with T5 under the condition of constant illumination; (3) the COP of the two chillers is 4.7 and 4.6 respectively, the cooling capacity has been greatly attenuated, the efficiency of cooling tower is also low, and the maintenance is needed. 4 in the case of no fresh air supply, two 1067RT units can meet the refrigeration needs, such as opening fresh air to open the spare 660RT screw unit; (5) the installation of exhaust heat recovery system consumes 649,000 kWh power more than that without fresh air, and saves 254,000 kWh power compared with open fresh air mode; (6) reasonable setting up time of air conditioning system can save 256,000 kWh power consumption in the air conditioning season, which accounts for 6.6% of the total power consumption of air conditioning system.
