Freon Charging process in Split AC

Size charging freon on ac split
What size freon psi should we fill into our ac, it depends on the amount of weight the existing freon, probably mostly for the moment still using R22, the amount of pk does not fully measure of how psi air conditioning but should consider the indoor and the outdoor distance because the farther the more contents, there you can fill freon in accordance with the needs you need to remember to use it if it's right or it is cold more quickly achieved, you need power too much, and the compressor work is quite heavy, but the temperature is reached quickly, compressor must quickly stop, if we fill freon as needed for indoor course enough freon contents not too much enough time to cool the compressor works a little but not too hard. indeed in the installation of ordinary people use the benchmark of contents Compressor out of the shop door is already filled in the benchmark typically max pipe length 5 m, and we have seen this many experts do not carry power analyzer or Vacuum, higt He just opened the press, let lowpress in the open ring indoor air in the pipe exit, after it in the run to speed up time, whereas here much harm consumers, which will quickly lead to engine damage.

Because at the time of installation is in need analyzer or vacuum, because what if the excess freon then amphere big power amps, certainly not in the ad fakum trapped air due to its cooling will be reduced, and also not be knew pipeline leak when pemasangan.Untuk size usually about 30 psi psi to 50 psi, do not measure how much electricity as a result of freon pressure amphere larger.2 .no in fakum sure no air is trapped due to reduced cooling. nameplat while we look at the comp, usually must be listed under the running.

Learning to fill freon split ac
First of all you have done in filling the freon is split ac operate.
after getting the outdoor unit power supply of the indoor unit, open nepel freon filling valve cover with a wrench.
then attach the blue hose on the manifold that are in nipple charging freon, freon pressure is there? by looking at the low pressure manifold needle blue reply.
if there is no freon pressure at all, it means the cooling system / split ac no leaks.
looking to see where the leak with a small brush soapy water that was given, if not repaired / welded leak freon will be reduced back despite being filled to split ac to cool again.

If space leaks must be repaired by means of welding and cooling systems / ac split still contained residual freon, then you should do that before doing repairs / welding is to remove the residual freon so as not to endanger yourself.

if the leak has been found and has been repaired / welded, cooling system / split ac vacuum must be filled first before freon, using engine vacuum.
vacuum that both should reach 30 ", then what if you do not have a vacuum machine ???
take it easy there are still ways, namely by using a compressor / outdoor unit which we will fill freonnya, the way he is:
1 pair of blue hose to the nipple and freon charging hose yellow on the tube Freon (Freon saved faucet position within the state of both valves fully open and fully closed on the manifold).
2. open the faucet nepel 3/8 size imaginable on the right side of the outdoor unit nepel faucet.
3 key input nepel 3/8 L on faucet and turn to the right (nepel closed valve position).
4. operated ac split and wait until the indoor unit outdoor unit gets power supply.
5. after the outdoor unit operation, disconnect the hose from the manifold blue, the wind will come out of the blue end of the hose and wait until the wind does not come out again from the end of the blue hose.
6 after no wind comes out again from the end of the blue hose, replace the blue end of the hose to the manifold and turn the key to the left of L which is at 3/8 nepel faucet (faucet nepel fully open position).
7 contents by turning the faucet manifold freon blue needle towards the left while looking to make sure how much freon manifold which has entered into the cooling system / ac split.
at the time of filling the freon do it gradually not all at once in a short time, so as not to damage the compressor valves.
open faucet manifold ...... ...... .. .. briefly and then close again, do repeatedly and see how much freon that has been entered on the needle dimanifold imaginable, until the installation of the pipe size 3/8 ac which is at the outdoor unit that dewy wet or existing in the indoor evaporator units you hold, if the cold has been uneven mean freon charging process is enough, do not need 75 psi.
when the excess freon ac unit would make ac not cold not be made ​​cooler. note also the amperage charging freon compressor on time, not to exceed the limit amperage (current) that you can see on the side of the indoor unit.
