Laboratory pure water supply mode / 實(shí)驗(yàn)室純水供應(yīng)模式
Central pure water supply mode / 中央純水供應(yīng)模式
Central pure water supply mode refers to setting pure water production device. Water for laboratory use is transported to each water demanding point through water supply pipelines, providing direct access to laboratory pure water or ultra pure water, whether it is a single laboratory or an experimental building.
中央純水供應(yīng)模式是指設(shè)置純水生產(chǎn)裝置，實(shí)驗(yàn)室用水通過供水管道輸送到各個實(shí)驗(yàn)室用水點(diǎn)，無論是單個實(shí)驗(yàn)室還是一幢實(shí)驗(yàn)樓直接獲取實(shí)驗(yàn)室純水或超純水。
Advantages 優(yōu)點(diǎn)：
1. Lower running cost, centralized management.
   運(yùn)行成本低，管理集中。
2. Collective use, no possibility of machine standing idle.
   集體使用，不存在機(jī)器閑置可能。
3. Large production, water is delivered by pipe network, many water supply points in one laboratory.
   產(chǎn)量大，用水采用管網(wǎng)化，同一實(shí)驗(yàn)室多點(diǎn)取水。
Disadvantages 缺點(diǎn)：
The system must ensure long-term safe operation, otherwise there will exist water-breaking risk.
   系統(tǒng)必須保證長期安全運(yùn)行，否則存在斷水風(fēng)險。
Decentralized water supply mode / 分散純水供應(yīng)模式
Decentralized water supply mode refers to setting water purification machine or purified water on each water supply point of laboratory.
分散純水供應(yīng)模式是指在實(shí)驗(yàn)室各用水點(diǎn)位置設(shè)置純水機(jī)或成品水。
Advantages 優(yōu)點(diǎn)：
People have independent access to instruments, and instruments have high utilization ratio.
儀器有單獨(dú)的使用權(quán)，使用率高。
Disadvantages 缺點(diǎn)：
1. Operating cost is high, management is decentralized, and consumption cost is relatively higher.
運(yùn)行成本高，管理分散，消耗成本相對較高。
2. Fixed-point installation on desk, fixed water supply points. Small production, low flow-rate and low efficiency.
桌面定點(diǎn)臺式安裝，定點(diǎn)取水，機(jī)型產(chǎn)量小，流量小，工作效率低。
3. If each experimental group purchases separately, then the total amount of investment on this product will be very high, and will result in vacancy rate increasing with the different working conditions of each experimental group, proving unfavorable for the maximization of investment efficiency.
若每個實(shí)驗(yàn)組單獨(dú)購買，那么該類產(chǎn)品上的投資總額就會非常高，而且會隨著每個實(shí)驗(yàn)組工作情況不同而導(dǎo)致空置率提高，不利于投資效率******化。
With the development of laboratory equipment, pipe network and centralization of laboratory pure water supply have become the developing direction of large scale experimental buildings.
隨著實(shí)驗(yàn)室裝備的發(fā)展，實(shí)驗(yàn)室供水的管網(wǎng)化與集中化已成為大型實(shí)驗(yàn)樓純水供應(yīng)的發(fā)展方向。
