制冷機日常維護：
1、加油
1）當油位低于視鏡1/4時，應及時補充潤滑油
2）將加油管一端連接壓縮機進氣端的加油閥，微開加油閥，利用系統中的壓力將加油管內的空氣排出，另一端插入油桶內
3）適當關小系統制冷劑供液閥，并調整吸氣低壓報警設置，以免因壓力過低而停車
4）當吸氣壓力低于大氣壓時，打開加油閥，油會自動進入壓縮機內
5）當油位超過視鏡5/6時，應停止加油操作：先關加油閥，再打開系統供液閥，恢復正常
2、補充制冷劑
1）當判斷系統缺液時，應及時給系統加氟
2）將加氟管一端與系統加氟口相連，另一端與氟瓶相連，通過加氟軟管趕出管內的空氣
3）先打開氟瓶的閥門，確認無泄漏后再開加氟口處的閥門
4）R23系統應將瓶口朝上，而R404A系統應將瓶口朝下，以保證迅速加氟
5）加氟結束時，應先關閉氟瓶的閥門，再關加氟口的閥門
6）制冷劑添加一次不可過多，以免排氣壓力過高。如一次添加不足，可重復進行
7）判斷系統液位正常的依據是，R23系統為停車均壓后的壓力值在6~8bar之間，R404A系統運行中冷凝器的液位在視鏡的1/5~2/5處
3、放空氣
1）當系統壓力明顯高于相應溫度下的飽和壓力時，應考慮放空氣
2）由于空氣只集中在高壓部分，所以應通過冷凝器的排空閥操作
3）高溫系統應在停車時進行，低溫系統**在運行時進行
4）具體操作要精心，絲堵不要開啟過大，也不要遠離現場
5）空氣操(cao)作(zuo)應分(fen)幾次進行，不可一次放(fang)(fang)氣太(tai)多(duo)，以免放(fang)(fang)出過量的制冷劑 [4
