(1）制冷劑的充注。現(xiàn)在，鹽水機(jī)組在出廠前通常都按規(guī)則充注了制冷劑，現(xiàn)場(chǎng)安裝后，外觀檢查假如未發(fā)現(xiàn)意外損傷，可直接翻開有關(guān)閥門（應(yīng)先閱覽廠方的運(yùn)用說明書，在運(yùn)送途中，機(jī)組上的閥門通常處在封閉狀況）開機(jī)調(diào)試。假如發(fā)現(xiàn)制冷劑已經(jīng)漏完或許缺乏，應(yīng)首先找出走漏點(diǎn)并排除走漏現(xiàn)象，然后按商品運(yùn)用說明書請(qǐng)求，加人規(guī)則商標(biāo)的制冷劑．留意制冷劑充注量應(yīng)契合技術(shù)要求。

(1) refrigerant. Now, saline water machine in the factory usually according to the rules of filled with refrigerant, on-site after installation, check the appearance if an undetected accidental injury, directly open the valve should be first reading of the factory according to the descriptions in transit, the valve unit usually in closed) commissioning. If you find that the refrigerant has been leaking after may lack, should first find out the leak and eliminate leakage phenomenon, then according to the commodity based on the specification request, adds the trademark rules of refrigerant. Note that the refrigerant filling quantity should be in conformity with the technical requirements.

(2）有些鹽水機(jī)組需要在用戶現(xiàn)場(chǎng)充注制冷劑，制冷劑的充注量及制冷劑牌號(hào)必需依照規(guī)則。制冷劑充注量缺乏．會(huì)招致冷量缺乏。制冷劑充注量過多，不但會(huì)增加費(fèi)用，而且對(duì)運(yùn)轉(zhuǎn)能耗等可能帶來不利影響。

(2) some units need saline at the user's site of refrigerant, the refrigerant filling quantity of refrigerant and grade must be in accordance with the rules. The refrigerant charge will lead to lack of cooling capacity lack. The refrigerant charge too much, will not only increase the cost of operation, and energy consumption may adversely affect.

(3）在充注制冷劑前，應(yīng)預(yù)先備有滿足的制冷劑。充注時(shí)，可直接從專用充液閥門充入。因?yàn)轶w系處于真空狀況，鋼瓶中制冷劑與體系壓差較大，當(dāng)翻開閥門時(shí)（應(yīng)先用制冷劑吹出連接管中的空氣，避免空氣進(jìn)人機(jī)組，影響機(jī)組功能），制冷劑敏捷由鋼瓶流人體系，充注完畢后，應(yīng)先將充液閥門封閉，再移去連接管。

(3) in the refrigerant, should meet the pre prepared refrigerant. When charging, can be directly from the special liquid filling valve. Because the system is in a vacuum condition, cylinder refrigerant and system pressure, when the valve is open (should first with refrigerant blowing air connection tube, avoid air into the unit, the impact of functional units), the refrigerant agile by cylinder flow system, after filling, the liquid filling valve is closed, to remove connecting tube.

(4）制冷系統(tǒng)調(diào)試。制冷劑充注完畢后（如需要充注制冷劑），能夠進(jìn)行負(fù)荷調(diào)試。由于近年來，鹽水機(jī)組在性能和電氣控制方面都有了長(zhǎng)足的進(jìn)步，許多鹽水機(jī)組在正式開機(jī)前能夠?qū)χ饕娍叵到y(tǒng)做模仿動(dòng)作檢側(cè)，即機(jī)組主機(jī)不通電，控制系統(tǒng)通電，然后經(jīng)過機(jī)組內(nèi)部設(shè)定，對(duì)機(jī)組的電控系統(tǒng)進(jìn)行檢測(cè)，組件能否運(yùn)轉(zhuǎn)正常。假如電控系統(tǒng)出現(xiàn)什么問題，能夠及時(shí)處理。最后再通上主機(jī)電源，進(jìn)行調(diào)試。在調(diào)試過程中，應(yīng)特別留意以下幾點(diǎn)：

(4) debugging of refrigeration system. After the refrigerant (if need refrigerant), can load debugging. Because in recent years, saline water machine in terms of performance and electrical control have great progress, many saline water machine before the official start to of main electric control system simulation of the action side inspection, that unit is not energized, the control system is energized, and then through the internal generator set, the electrical control system of the unit were detected, components can work normally. What if the problem of electronic control system, timely treatment. Finally, through the host power supply, debugging. In the debugging process, should pay special attention to the following points:

1）檢查制冷體系中的遍地閥門是不是處在正常的敞開狀況，特別是排氣截止閥，切勿封閉。

1) check valve in a refrigeration system and is not in the normal open state, especially the exhaust valve not closed.

2）翻開冷凝器的冷卻水閥門和蒸發(fā)器的冷水閥門，冷水和冷卻水的流量應(yīng)契合廠方提出要求。

2) open the cold water valve of condenser cooling water valve and an evaporator, cold water and cooling water flow should fit the requirements.

3）發(fā)動(dòng)前應(yīng)留意調(diào)查機(jī)組的供電電壓是不是正常。

3) should pay attention to the supply voltage before starting the investigation unit is not normal.

4）依照廠方供給的開機(jī)手冊(cè)，發(fā)動(dòng)機(jī)組。

4) in accordance with the manufacturer supplied on manual engine group.

5）當(dāng)機(jī)組啟動(dòng)后，依據(jù)廠方提供的開機(jī)手冊(cè)，查看機(jī)組的各項(xiàng)參數(shù)能否正常。

5) when the unit is started, according to the operation manual, check whether the normal parameters of the unit.

6）可依據(jù)廠方提供的螺桿式冷水機(jī)組運(yùn)轉(zhuǎn)數(shù)據(jù)記載表， 對(duì)螺桿式冷水機(jī)組的各項(xiàng)數(shù)據(jù)停止記載，特別是一些主要參數(shù)一定要記載分明。

6) according to the manufacturer to provide the screw type chiller operation data records list, the data of screw chillers stop records, especially some of the main parameters must be clearly documented.

7）在鹽水機(jī)組運(yùn)轉(zhuǎn)過程中，應(yīng)留意緊縮機(jī)的上、下載機(jī)構(gòu)能否正常工作。

7) in the operation of the brine unit, should pay attention to the tightening machine, download the body can work properly.

8）應(yīng)準(zhǔn)確運(yùn)用制冷體系中安裝的安全保護(hù)設(shè)備，如高低壓保護(hù)設(shè)備、冷水和冷卻水?dāng)嗨髁块_關(guān)、安全閥等設(shè)備，如有損壞應(yīng)及時(shí)替換。

8) should be accurately on the basis of safety protection equipment installed in a refrigeration system, such as high and low voltage protection device, cold water and cooling water water flow switch, safety valve and other equipment, if damage should be promptly replaced.

9）鹽水機(jī)組如出現(xiàn)異常情況，應(yīng)立即停機(jī)檢查。

9) if the abnormal situation occurs, the unit should be stopped immediately.

在制冷系統(tǒng)調(diào)試前， 一定要做好空調(diào)系統(tǒng)內(nèi)部的清潔和枯燥工作。假如前期工作不認(rèn)真停止，在調(diào)試期間將會(huì)增加許多工作量，而且會(huì)給制冷安裝以后的運(yùn)轉(zhuǎn)帶來許多隱患。

Before the refrigeration system is debugged, must do well the air conditioning system interior clean and dry work. If the previous work does not seriously stop, in the commissioning period will increase a lot of work, and will bring many hidden dangers to the operation of the refrigeration installation.
