【文章內容簡介】 進行考慮。 2. Air conditioning energy conservation system research survey 1) Through the load control, achieves the energy conservation goal. (a) The 6 burning hot season new atmosphere load occupies the entire cold load 2540%, reduces the new atmosphere load, reduces the new atmosphere energy consumption, the choice smallest essential new amount of wind, also can achieve the goal. But the new amount of wind smallest supply on the one hand the country had the standard, moreover the new amount of wind insufficient will affect the air quality, will endanger the human body health. (b) Outside the optimized construction the surrounding protection structure energy conservation design, uses the heat preservation thermal insulation material technology, reduces the air conditioning load, the realization construction energy conservation, but simultaneously also causes the building cost rise, the promotion to receive the certain limit. 2.空調節(jié)能系統(tǒng)的研究概況 1)通過負荷控制 ,達到節(jié)能目的。 ① 炎熱季節(jié)新風負荷占到整個冷負荷的2540%,減少新風負荷,降低新風能耗,選擇最小必要新風量,也能達到目的。但是新風量的最小供應一方面國家已有標準,另外新風量不足將影響空氣質量,危及人體健康。 ② 優(yōu)化建筑外圍護結構的節(jié)能設計,采用保溫隔熱材料技術,降低空調負荷,實現 建筑節(jié)能,但同時也導致建筑成本上升,推廣受到一定的限制。 2) gathers can the air conditioning. Gathers coldly through the ice, avoids the daytime to use electricity the peak, at night stores up the air conditioning freezing water refrigeration, daytime does not start the air conditioning main engine only to use the aqueous system to circulate. This method itself certainly does not conserve energy the province electricity, but optimized the electrical work power supply, to already implemented the time sharing electrovalence the area, played to economize does not conserve energy the role, had the area promotion significance. 2)蓄能空調。通過冰蓄冷,避開白天的用電高峰,夜間將空調冷凍水制冷儲存起來,白天不開動空調主機僅使用水系統(tǒng)循環(huán)。這種方法本身并不節(jié)能省電,而是優(yōu)化了電網供電,對已經實行分時電價的地區(qū),起到 省錢不節(jié)能 的作用,具地區(qū)性推廣意義。 3) water source heat pump. Is opposite says to the air and the soil, the water is the most ideal spatial transfer cold heat source, the water source heat pump also therefore has the environmental protection, is highly effective, the energy conservation and so on the multitudinous merit, but our countr y water source heat pump engineering research is not very mature, pares with some developed countries also has the certain disparity. At the same time, the water source heat pump although has very many merits, but receives the geology, the environment, the policy 7 and so on the limit quite is also big, this caused the water source heat pump to be restricted in an our country more widespread application. 3)水源熱泵。相對于空氣和土壤而言,水是最為理想的空調用冷熱源,水源熱泵也因此具有環(huán)保、高效、節(jié)能等眾多優(yōu)點,但我國水源熱泵技術研究還不是很成熟,與一些發(fā)達國家相比還存在一定的差距。同時,水源熱泵盡管具有很多優(yōu)點,但所受的地質、環(huán)境、政策等的限制也比較大,這就使得水源熱泵在我國更廣泛的應用受到了限制。 4) In the central airconditioning system individually consumes energy the equipment energy conservation transformation. (a) Air blower and water pump general frequency changer velocity modulation energy conservation, this is at present uses more technologies. This method simple practical, electricity saving effect obvious, but product and so on water pump, air blower is the system auxiliary engine partially, occupies the overall system energy consumption approximately is 40%, therefore the excavation space is limited. (b) The refrigeration main engine, the refrigeration unit39。s power consumption holds the very big share in the airconditioning system, saves this part of consuming energy is the entire airconditioning system economy movement key. At present generally all uses reduces the indoor temperature standard, enhances the cold water temperature and so on the measure realization refrigeration main engine energy several methods deficiency has only considered the partial energy conservation, but had not considered from the overall system overall situation. 4)中央空調系統(tǒng)中單個耗能設備節(jié)能改造。 ① 風機和水泵通用變頻器調速節(jié)能,這是目前采用較多的技術。這種方法簡便實用,節(jié)電效果明顯,但水泵、風機等產品屬系統(tǒng)輔機部分,占整個系統(tǒng)能耗約為 40%,所以挖掘空間有限。 ②制冷主機,制冷機組的耗電量在空調系統(tǒng)中占有很大份額,節(jié)約這 部分的耗能是整個空調系統(tǒng)經濟運行的關鍵。目前一般都采用降低室內溫度標準、提高冷水初溫等措施實現制冷主機的節(jié)能。上面幾種方法的不足之處是僅考慮了局部的節(jié)能,而 沒 有從整個系統(tǒng)的全局去考慮。 5) the dynamic load track energy conservation control system take the entire central airconditioning system as a body, unceasingly changes the condition according to the air conditioning area load, through changes in the main engine and the circulatory system various parameters movement change situation, the lock following load change, realizes in meets the load need under the premise the prompt quota supplies cold quantity, namely achieves according to must supply, basically 8 achieved does not lag, are not many for, many gives the goal. This method not only pared with the permanent current capacity water pump gentle breeze machine has realized the auxiliary engine largest scale energy conservation, moreover optimized the main engine movement operating mode, might achieve the overall system conserved energy 1535%. This is this topic research key point. 5)動態(tài)負荷跟蹤的節(jié)能控制系統(tǒng)以整個中央空調系統(tǒng)為一體,根據空調區(qū)負荷不斷變化的狀況,通過改變主機及循環(huán)系統(tǒng)內各參數運
