摘要：論述了一個(gè)智能中央空調(diào)節(jié)能系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)，在實(shí)現(xiàn)中，較好地運(yùn)用了系統(tǒng)工程的思想，集成經(jīng)典控制理論、變頻器控制、組態(tài)軟件、分布式網(wǎng)絡(luò)等手段，使整個(gè)系統(tǒng)運(yùn)行良好，實(shí)現(xiàn)了預(yù)定的節(jié)能目標(biāo)。

This paper introduces an implement of a smart central air-condition, energy saving system. Tools such as PID control, transducer control, DCS,DDC are integrated into the system and they work together to reach the goal-energy saving-successfully.
Keywords：central air-condition, energy saving, Distributing Control System(DCS), Direct Digit Control(DDC)
