【摘要】：隨著人們對工作和居住環(huán)境要求的提升，中央空調(diào)的應(yīng)用越來越廣泛。中央空調(diào)的大范圍應(yīng)用一方面改善了人們的生活質(zhì)量，另一方面給節(jié)能減排帶來了可觀效益。因此，其應(yīng)用范圍已經(jīng)從以往的商業(yè)、工業(yè)領(lǐng)域轉(zhuǎn)向民用住宅、辦公樓宇等，逐漸與日常生活息息相關(guān)。有數(shù)據(jù)統(tǒng)計，國內(nèi)超六成中高檔樓宇安裝了中央空調(diào)，而中央空調(diào)系統(tǒng)能耗占據(jù)整個建筑能耗一半以上。合理控制中央空調(diào)系統(tǒng)、限制空調(diào)能耗已經(jīng)成為建筑節(jié)能的一個發(fā)展方向。 傳統(tǒng)空調(diào)系統(tǒng)采用分散控制，與控制算法結(jié)合程度不高，對系統(tǒng)的操作繁瑣并且控制精度差，難以達(dá)到節(jié)約能源的作用。本論文主要研究了PID控制器的構(gòu)成，調(diào)節(jié)規(guī)律和控制規(guī)則，并結(jié)合MCGS組態(tài)軟件和PID控制算法，對空調(diào)系統(tǒng)實現(xiàn)了集中控制。同時對中央空調(diào)結(jié)構(gòu)和機組運行原理進(jìn)行了簡介，對于本系統(tǒng)如何運用到MCGS組態(tài)軟件完成上位機設(shè)計和外部設(shè)備連接做了詳盡說明；針對中央空調(diào)系統(tǒng)的特點，，采用常規(guī)PID控制策略，編寫MCGS控制腳本程序時結(jié)合了PID控制算法，實現(xiàn)了PID控制在程序中的應(yīng)用。在對系統(tǒng)進(jìn)行調(diào)試和現(xiàn)場運行試驗中系統(tǒng)工作正常。結(jié)果表明，在中央空調(diào)控制系統(tǒng)中，PID控制器具有良好的適應(yīng)性。
[Abstract]:With the improvement of working and living environment, the application of central air-conditioning is more and more extensive. On the one hand, the wide application of central air conditioning improves people's quality of life, on the other hand, it brings considerable benefits to energy saving and emission reduction. Therefore, its application scope has changed from the past commercial, the industrial domain to the civilian residence, the office building and so on, gradually is closely related with the daily life. According to statistics, more than 60% of the buildings in China have installed central air conditioning, and the energy consumption of central air conditioning system accounts for more than half of the energy consumption of the whole building. Reasonable control of central air-conditioning system and restriction of air-conditioning energy consumption have become a development direction of building energy-saving. The traditional air conditioning system adopts decentralized control, which is not highly combined with the control algorithm, and the operation of the system is cumbersome and the control precision is poor, so it is difficult to achieve the function of energy saving. In this paper, the composition, regulation law and control rules of PID controller are studied. Combined with MCGS configuration software and PID control algorithm, centralized control of air conditioning system is realized. At the same time, the structure of central air conditioning and the operation principle of the unit are introduced in detail, and how to use the MCGS configuration software to complete the design of upper computer and the connection of external equipment is described in detail, and the characteristics of the central air conditioning system are pointed out. Using the conventional PID control strategy, the application of PID control in the program is realized by combining the PID control algorithm when writing the MCGS control script program. The system works normally in debugging and field running test. The results show that the pid controller has good adaptability in the central air conditioning control system.
