进行考虑。 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.空调节能系统的研究概况 1)通过负荷控制 ,达到节能目的。 ① 炎热季节新风负荷占到整个冷负荷的2540%,减少新风负荷,降低新风能耗,选择最小必要新风量,也能达到目的。 但是新风量的最小供应一方面国家已有标准,另外新风量不足将影响空气质量,危及人体健康。 ② 优化建筑外围护结构的节能设计,采用保温隔热材料技术,降低空调负荷,实现 建筑节能,但同时也导致建筑成本上升,推广受到一定的限制。 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)蓄能空调。 通过冰蓄冷,避开白天的用电高峰,夜间将空调冷冻水制冷储存起来,白天不开动空调主机仅使用水系统循环。 这种方法本身并不节能省电,而是优化了电网供电,对已经实行分时电价的地区,起到 省钱不节能 的作用,具地区性推广意义。 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)水源热泵。 相对于空气和土壤而言,水是最为理想的空调用冷热源,水源热泵也因此具有环保、高效、节能等众多优点,但我国水源热泵技术研究还不是很成熟,与一些发达国家相比还存在一定的差距。 同时,水源热泵尽管具有很多优点,但所受的地质、环境、政策等的限制也比较大,这就使得水源热泵在我国更广泛的应用受到了限制。 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)中央空调系统中单个耗能设备节能改造。 ① 风机和水泵通用变频器调速节能,这是目前采用较多的技术。 这种方法简便实用,节电效果明显,但水泵、风机等产品属系统辅机部分,占整个系统能耗约为 40%,所以挖掘空间有限。 ②制冷主机,制冷机组的耗电量在空调系统中占有很大份额,节约这 部分的耗能是整个空调系统经济运行的关键。 目前一般都采用降低室内温度标准、提高冷水初温等措施实现制冷主机的节能。 上面几种方法的不足之处是仅考虑了局部的节能,而 没 有从整个系统的全局去考虑。 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)动态负荷跟踪的节能控制系统以整个中央空调系统为一体,根据空调区负荷不断变化的状况,通过改变主机及循环系统内各参数运。外文文献及翻译:空调节能技术的研究howairconditionersenergyconservationtechnology
