在系(xi)統(tong)上電后，首(shou)先對(dui)各個變頻(pin)空(kong)(kong)(kong)壓(ya)機(ji)(ji)進行初(chu)始(shi)化，除了設置變頻(pin)空(kong)(kong)(kong)壓(ya)機(ji)(ji)獨立運(yun)行所需的(de)寄(ji)存器外，空(kong)(kong)(kong)壓(ya)機(ji)(ji)配件還必須設置其(qi)聯機(ji)(ji)相關的(de)參(can)數．在空(kong)(kong)(kong)壓(ya)機(ji)(ji)接入CAN總(zong)線(xian)(xian)前(qian)，要(yao)手工(gong)給空(kong)(kong)(kong)壓(ya)機(ji)(ji)設置一(yi)(yi)個不與同(tong)一(yi)(yi)總(zong)線(xian)(xian)上的(de)空(kong)(kong)(kong)壓(ya)機(ji)(ji)重(zhong)復的(de)編(bian)號，這個編(bian)號主(zhu)要(yao)用在總(zong)線(xian)(xian)仲裁(cai)中．如果(guo)同(tong)一(yi)(yi)總(zong)線(xian)(xian)上有兩臺(tai)空(kong)(kong)(kong)壓(ya)機(ji)(ji)的(de)編(bian)號是一(yi)(yi)樣的(de)，信息(xi)的(de)傳送會沖(chong)突(tu)，系(xi)統(tong)不能(neng)正常工(gong)作．

    制冷系統(tong)工作壓力檢測的(de)(de)方法:將壓力表(biao)組正確連(lian)接(jie)(jie)到制冷系統(tong)相應(ying)的(de)(de)檢修閥上(shang)，同時(shi)連(lian)接(jie)(jie)好發(fa)動(dong)機(ji)轉(zhuan)速表(biao)。關閉(bi)壓力表(biao)組上(shang)的(de)(de)兩個手動(dong)截止閥，用手擰松壓力表(biao)組上(shang)高(gao)低(di)壓注入軟管的(de)(de)連(lian)接(jie)(jie)螺母，讓系統(tong)內(nei)的(de)(de)制冷劑將高(gao)低(di)管內(nei)的(de)(de)空氣(qi)排出，然后再將連(lian)接(jie)(jie)螺母擰緊。起動(dong)發(fa)動(dong)機(ji)并使(shi)發(fa)動(dong)機(ji)轉(zhuan)速保持在(zai)1250r/min，

    然后閉合(he)空(kong)調(diao)A/C開關和鼓風機(ji)(ji)開關，設(she)置到空(kong)調(diao)最大制冷狀態，鼓風機(ji)(ji)高速運轉，溫(wen)度(du)調(diao)節在最冷。關閉車門、車窗和艙蓋，發(fa)動機(ji)(ji)預(yu)熱。把溫(wen)度(du)計插進中間出風口并觀(guan)察(cha)空(kong)氣(qi)溫(wen)度(du)，在外界(jie)溫(wen)度(du)為27℃時，運行5min后出風溫(wen)度(du)應接近于7℃。觀(guan)察(cha)高、低壓側壓力。

    壓(ya)(ya)(ya)(ya)(ya)縮機(ji)吸入(ru)來自蒸發器的(de)低溫(wen)(wen)低壓(ya)(ya)(ya)(ya)(ya)的(de)制冷劑(ji)蒸汽, 將之壓(ya)(ya)(ya)(ya)(ya)縮成(cheng)高溫(wen)(wen)高壓(ya)(ya)(ya)(ya)(ya)的(de)制冷劑(ji)氣體(ti)。按其能量(liang)輸出方式(shi)可分為固定排(pai)量(liang)壓(ya)(ya)(ya)(ya)(ya)縮機(ji),內部(bu)調(diao)節(jie)的(de)變排(pai)量(liang)壓(ya)(ya)(ya)(ya)(ya)縮機(ji)和(he)外部(bu)調(diao)節(jie)的(de)變排(pai)量(liang)壓(ya)(ya)(ya)(ya)(ya)縮機(ji)。
