電容器放電:應以安全的方式進行,以避免產生火花的可能性;
充注、回收或清洗系統時,沒有帶電的電氣元件和線路暴露在外;
接地連接具有連續性。

7. 密封元件的修理

1) 在修理密封元件過程中,在拆除密封蓋等之前,應將所有電源與正在工作的設備斷開。如果在維修過程中必須

為設備供電,則最關鍵的點應有永久運行的洩漏檢測形式,以警告潛在的危險情況。

2) 應特別注意以下事項,以確保在對電氣元件進行操作時,不會改變外殼從而影響防護等級,包括電纜損壞、連

接數量過多、端子不符合原始規格、密封件損壞、壓蓋安裝不正確等。
確保設備安裝牢固。
確保密封件或密封材料沒有退化,以確保其能夠起到防止可燃氣體進入的作用。更換零件應符合製造商的規格。
注意:使用矽密封膠可能會抑制某些類型的洩漏檢測設備的有效性。本安組件在處理之前不必隔離。

8. 本安組件維修

請勿在電路上施加任何永久性電感或電容負載,除非確保不會超過所用設備的允許電壓和電流。本安元件是唯
一可以在有易燃氣體的情況下工作的類型。測試設備應處於正確的額定值。只能使用製造商指定的部件更換元
件。其他部件可能會因洩漏而導致大氣中的製冷劑著火。

9. 佈線

檢查佈線是否會受到磨損、腐蝕、過度壓力、振動、銳邊或任何其他不利環境影響。檢查還應考慮壓縮機或風
扇等造成的老化或持續振動的影響。

10. 可燃製冷劑檢測

在任何情況下都不得使用潛在的點火源尋找或檢測製冷劑洩漏。
不得使用鹵素燈(或任何其他使用明火的探測器)。

11. 洩漏檢測方法

以下洩漏檢測方法適用于含易燃製冷劑的系統。應使用電子檢漏儀檢測易燃製冷劑,但靈敏度可能不夠,或
者可能需要重新校準。(檢測設備應在無製冷劑的區域進行校準。)確保檢測器不是潛在的點火源並且適合
所使用的製冷劑。洩漏檢測設備應設置為製冷劑LFL的百分比,並應根據所使用的製冷劑進行校準,並確認
適當的氣體百分比(最大25%)。檢漏液適用於大多數製冷劑,但應避免使用含氯的清潔劑,因為氯可能與
製冷劑發生反應並腐蝕銅管。如果懷疑有洩漏,應移走/熄滅所有明火。如果發現需要釺焊的製冷劑洩漏,
則應從系統中回收所有製冷劑,或將系統中遠離洩漏的部分隔離(通過截止閥)。然後,在釺焊過程之前和
過程中,應通過系統吹掃無氧氮氣(OFN)。

12. 清除和排空

當進入製冷劑回路進行維修或出於任何其他目的時,應使用常規程序。然而,重要的是遵循最佳做法,因為
需要考慮易燃性。不得通過釺焊打開製冷系統。應遵循以下程序:
清除製冷劑;
用惰性氣體吹掃電路;
排空;
再次用惰性氣體吹掃;
通過切割或釺焊打開電路。
應將充注的製冷劑回收到適當的回收鋼瓶中。系統應使用OFN進行沖洗以確保設備安全。這一過程可能需要
重複幾次。此程序不得使用壓縮空氣或氧氣。
沖洗時用OFN打破系統中的真空並繼續填充直到達到工作壓力,然後排放到大氣中,最後抽真空來實現。應
重複此過程,直到系統內沒有製冷劑為止。
當使用最終OFN充注時,系統應排放至大氣壓力以進行工作。如果要在管道上進行釺焊操作,此操作至關重要。
確保真空泵的出口不靠近任何點火源,並且有通風。

13. 充注程序

除常規充注程序外,還應遵循以下要求。確保在使用充注設備時不會發生不同製冷劑的污染。軟管或管線應
盡可能短,以儘量減少其中的製冷劑含量。
鋼瓶應保持直立。
在向系統充注製冷劑之前,確保製冷系統已接地。
充注完成時給系統貼上標籤(如果還未貼)。
應特別注意不要將製冷系統裝得過滿。
在給系統充注之前,應使用OFN對其進行壓力測試。系統應在充注完成後試運轉之前進行洩漏測試。離開現
場前應進行後續洩漏測試。
