汽包水位 給水流量 蒸汽流量 三沖量 自動(dòng)控制系統(tǒng) 燃燒過程控制在賓館里，中央空調(diào)是不可決少的，耗電非常大，空調(diào)主要是用來實(shí)現(xiàn)室內(nèi)的恒溫，中央空調(diào)主要由制冷機(jī)、冷卻水循環(huán)系統(tǒng)、風(fēng)機(jī)盤管系統(tǒng)、風(fēng)機(jī)和冷卻塔等組成。中央空調(diào)工作原理圖如圖1所示。通常冷凍水泵的容量是按最高溫度、滿住率，并在此基礎(chǔ)上留有10-20%的余量設(shè)計(jì)，在一年四季中，水泵系統(tǒng)長期在固定的最大水流量工作，由于季節(jié)、晝夜及住房率變化大，空調(diào)實(shí)際的熱負(fù)載在絕大部分時(shí)間內(nèi)遠(yuǎn)比設(shè)計(jì)負(fù)載低。與決定水泵流量和壓力的最大設(shè)計(jì)負(fù)載（負(fù)荷率100%）相比，一年中負(fù)荷率在50%以下的運(yùn)行時(shí)間將近一半，一般冷凍水設(shè)計(jì)溫度為5---7℃，而事實(shí)上在全年決大部分時(shí)間冷凍水的溫度僅為2---4℃，即水泵卻是全功率運(yùn)行，增加了管道能量損失，浪費(fèi)了水泵運(yùn)行的輸送能量。這就存在能量的無效使用，而通過變頻調(diào)速技術(shù)就能實(shí)現(xiàn)自動(dòng)調(diào)節(jié)流量并顯著節(jié)能的效果，用PLC改造傳統(tǒng)電氣控制系統(tǒng)的則使運(yùn)行可靠性大大加強(qiáng)。
