【摘要】：本文介紹了國(guó)內(nèi)外二次加壓供水方式的現(xiàn)狀及發(fā)展趨勢(shì)，，總結(jié)了建筑生活給水系統(tǒng)五種供水方式的優(yōu)缺點(diǎn)，列出了一系列適合于高層建筑、超高層建筑采用的生活并聯(lián)給水方式和串聯(lián)給水方式，講解了高層及超高層建筑進(jìn)行合理豎向分區(qū)的標(biāo)準(zhǔn)，總結(jié)了建筑生活給水系統(tǒng)中水力計(jì)算的基本公式。以酒店類公寓樓的供水方式為模擬對(duì)象，采用具有權(quán)威性的仿真模擬軟件FLOWMASTER，對(duì)該建筑的變頻調(diào)速供水系統(tǒng)進(jìn)行模擬與瞬態(tài)計(jì)算，得出系統(tǒng)運(yùn)行時(shí)的各項(xiàng)參數(shù)與時(shí)間的關(guān)系，并通過(guò)模擬結(jié)果圖來(lái)分析該建筑變頻調(diào)速供水方式是否可靠，校核工程中水泵的各項(xiàng)設(shè)計(jì)參數(shù)是否合理、是否滿足用戶的各項(xiàng)要求，并對(duì)該系統(tǒng)提出優(yōu)化措施；通過(guò)計(jì)算結(jié)果對(duì)該超高層建筑生活給水系統(tǒng)做節(jié)能分析，最終提出在用戶用水低谷時(shí)期采用給水小泵供水是最經(jīng)濟(jì)、最節(jié)能的供水方式。 系統(tǒng)瞬態(tài)計(jì)算結(jié)果表明： ⑴五區(qū)供水系統(tǒng)的實(shí)際流量大于計(jì)算的理論流量，如果不對(duì)設(shè)備進(jìn)行優(yōu)化，必定會(huì)帶來(lái)能源的巨大損失。 ⑵工程中水泵吸水管的流速和管網(wǎng)中的流速都存在偏大或偏小的情況，因此對(duì)流速不恰當(dāng)?shù)墓芏芜M(jìn)行管徑優(yōu)化，以達(dá)到規(guī)范中的要求。 ⑶管網(wǎng)中的水壓能一直達(dá)到用戶端對(duì)水壓的要求，這也是變頻調(diào)速恒壓供水方式的優(yōu)點(diǎn)之一。 ⑷用水低谷時(shí)期，采用給水主泵進(jìn)行供水，水泵消耗的功率較大，消耗過(guò)多的電能，浪費(fèi)了資金。 ⑸根據(jù)對(duì)系統(tǒng)進(jìn)行優(yōu)化后的模擬計(jì)算可知，在用水量較小時(shí)段采用給水小泵供給用戶用水，能夠節(jié)約很多電能，值得對(duì)其推廣。
[Abstract]:This paper introduces the present situation and development trend of secondary pressurized water supply at home and abroad, summarizes the advantages and disadvantages of five kinds of water supply modes in building life water supply system, and lists a series of suitable water supply methods for high-rise buildings. The living parallel water supply mode and the series water supply mode used in the super high-rise buildings are explained the standard of reasonable vertical zoning for the high-rise and super high-rise buildings. The basic formula of hydraulic calculation in building water supply system is summarized. The water supply mode of hotel apartment building is taken as the simulation object. By using the authoritative simulation software FLOWMASTER, the simulation and transient calculation of the variable-frequency speed-regulating water supply system of the building are carried out, and the relationship between the parameters and the time when the system is running is obtained. The simulation result diagram is used to analyze whether the water supply mode of frequency conversion speed regulating in this building is reliable, whether the design parameters of the pump are reasonable in the checking project and whether it meets the requirements of the users, and puts forward the optimization measures for the system. Through the analysis of the energy saving of the water supply system of the super high-rise building, it is put forward that it is the most economical and the most energy saving way to supply water with small pump in the period of low water consumption. The transient calculation results show that:. The actual flow of water supply system in five regions is larger than the calculated theoretical flow. If the equipment is not optimized, it will bring huge loss of energy. 2 the flow rate of water pump suction pipe and the flow velocity of pipe network are both larger or smaller in the project, so the pipe diameter of the improper flow rate is optimized in order to meet the requirements of the specification. The water pressure energy in the pipe network has been up to the requirement of water pressure at the end of the user, which is also one of the advantages of the constant pressure water supply mode of frequency conversion speed regulation. In the period of low water use, the main pump is used to supply water, the pump consumes more power, consumes too much electric energy, and wastes funds. 5According to the simulation calculation after the optimization of the system, it can be known that the small pump can save a lot of electric energy in the period of small water consumption, which is worth popularizing.
