Research And Application Of The Central Air-conditioning Intelligent Control Conservation System

Now a day, we face an energy conjuncture with the condition getting more andmore badly. Energy saving of civil construction takes up the place to which we shouldpay more attention. Obviously, we know that the use of the energy (about electricity)consumed in central air conditioning system occupy 40% of the total. Especially, thetraditional ones with useless controller, not only waste a lot of energy but also can notmeet requires of new technology. Generally, an advanced control system shouldcompare with good function tending to saving energy and protecting environment. So,we need to research control system—it is a public business for us taking airconditioner and auto-control as career, to design an optimum control systemaccording to the right project, whatever, it just will be of significative to us.High precision (high need for temperature, humidity, etc.) air conditionersystem now becomes the basic technical guarantee of modem high technology lab.This page is aim to make a blue print of a auto-control system including configurationon software but also software and designing details, just based on the air conditionersystem used by National Measure and Testing Center.This thesis has been divided into 7 chapters, the full structure of contents andchapter details as following.Chapter 1,mainly review history of auto-control system development process,tell the application value of smart control system in air conditioner filed andsummarize conditions also features of its technology nowChapter2, make a particular explanation to central air conditioner controllingstation, controlling principle, software support and like that concepts.Chapter3,show you controlling specialty, surveillance strategy of HVAC,exchange ideas of main means on energy saving control, analysis selections ofdecreasing waste ways.Chapter4 to chapter6,by the way, analyzing target, drawing out plan, making useof centralized-distributed control technology, constructs controlling system withadvanced soft and hardware.Chapter7, summarize the design process. In my experience, feel the greatsuccess and power of DDC function matched with centralized-distributed technologyof computer. Then more, beautiful plan comes out for the future development.
