The main compressors of air conditioners are reciprocating compressors and rotary compressors.
空調(diào)器的主流壓縮機(jī)為往復(fù)式壓縮機(jī)和旋轉(zhuǎn)式壓縮機(jī)。

Different compressors, filling refrigeration oil methods and skills are not exactly the same, the following specific introduction.
不同的壓縮機(jī)，加注冷凍油的方 法和技巧不完全相同，以下具體介紹。

For reciprocating compressors, first pour the chilled oil into a clean, dry oil drum, then connect a clean, dry flexible pipe to the low pressure pipe, first fill the hose with oil to discharge the air, and then insert the hose into the oil drum.
對(duì)于往復(fù)式壓縮機(jī)，首先將冷凍油倒入一個(gè)清潔、干燥的油桶內(nèi)，再用一根清潔、干燥的軟 管接在低壓管上，先將軟管充滿油，以便排出空氣，再將此軟管插入油桶中。

Then start the compressor, so that the chilled oil is inhaled by the low pressure pipe, and stop when the chilled oil reaches the required amount.
然后啟動(dòng)壓縮機(jī)， 使冷凍油由低壓管吸入，當(dāng)冷凍油達(dá)到需要量后停機(jī)即可。

For rotary compressors, first pour the chilled oil into a dry, clean oil drum, and then seal the compressor's low pressure pipe, and connect a compound pressure gauge and vacuum gauge to the compressor's high pressure pipe.
對(duì)于旋轉(zhuǎn)式壓縮機(jī)，首先將冷凍油倒入一個(gè)干燥、清潔的油桶中，再將壓縮機(jī)的低壓管封 死，并在壓縮機(jī)的高壓管上接一只復(fù)合式壓力表和真空表。

Then start the vacuum pump, so that the compressor inside the vacuum, and then close the pressure regulator.
接著啟動(dòng)真空泵，使壓縮機(jī)內(nèi)部抽 成真空后再關(guān)閉調(diào)壓閥。

Then use a clean, dry hose connected to the low pressure valve, the hose is filled with oil first, in order to discharge the air to open the low pressure valve, the chilled oil is pressurized into the compressor, filled to the required amount.
再用一根清潔、干燥的軟管接在低壓閥上，先將軟管充滿油，以便排 出空氣開啟低壓閥，冷凍油被大氣壓入壓縮機(jī)，充至需要量即可。
