How do you exhaust an air conditioner? How does the air conditioner exhaust the air

Installing an air conditioner requires removing air from the copper pipes.

First of all, after fixing the internal and external units of the air conditioner respectively, the following operations are carried out in several steps:

1. Connect and tighten the internal and external air conditioning pipes normally, it is best to get some refrigeration oil to apply to the copper pipe bell mouth interface before fastening, refrigeration oil is available in refrigeration maintenance shops, 1 ml is not enough, this is to increase the tightness of the nozzle, remember to only apply refrigeration oil, if not, it is better not to coat, do not apply other things.

2. Open the valve of a thinner pipe (professionally called an exhaust pipe or liquid pipe).

3. Use a wrench to loosen the connection of the thicker pipe (professionally called the air pipe or air pipe) on the outdoor unit (that is, the brass screw cap on the pipe joint), and the straight road can hear the obvious sound of deflation, and the gas can be deflated for 5 seconds.

4. Quickly re-tighten the connecting nass of thicker pipes.

5. At this time, it is necessary to use soapy water to detect the leakage of all the interfaces connecting the pipes, the production of soapy water can find a sponge to penetrate the water and hit it with soap until it gently pinches the foam, smear the interface with soap foam, observe whether there are bubbles coming out, if there are bubbles coming out, it means that the leakage is there, and it must be tightened again (this link is very important, if the air conditioner is not good, it can not be used normally, or it will not take long to repair it normally).

6. After the leak detection is completed, the connecting line and bandaging pipeline can be debugged and used.

Remind a point, although you can install air conditioning in accordance with the above steps, but after all, this is a very professional technical work, a little careless, the light can not be used normally, and the serious can make the machine damaged on the spot, so it is recommended to find a professional to do it.

1.Use the refrigerant in the air conditioner to exhaust the air. First of all, we can unscrew the fluorine nozzle nut and back cover nut at the high and low pressure valves, and then open the high and low pressure spool, which will close after about 10 seconds.

2.Add freon to exhaust the air. We needed a separate refrigerant tank that connected the fluorine nozzle of the low-pressure valve to the piping of the separate refrigerant tank.

Once the connection is complete, we can slightly loosen the connection nut on the high-pressure valve and the refrigerant tank. valve, inject refrigerant, close the valve after about 2 3 seconds, wait about 10 15 seconds, tighten the connection nut. 3.

The vacuum pump discharges the air. Unscrew the nut of the valve's fluorine nozzle and connect the vacuum hose. Turn the "LO" knob counterclockwise and turn it on, then turn on the switch of the vacuum pump and evacuate.

After some time, vacuuming can be stopped. Finally, we need to unscrew the back nut of the valve and use a wrench to screw the valve core counterclockwise all the way so that the refrigeration system can be fully opened.

The steps to install the air conditioner and exhaust the air by yourself (a total of nine steps) are as follows:

1. Prepare a hex wrench and a movable wrench.

2. Remove the two screws (high and low pressure valves) of the empty dates.

3. Swap the two (high and low voltage) copper pipes in the figure below.

4. Tighten the high-pressure port screw with an adjustable wrench.

5. Do not tighten the low-pressure screws, leaving a margin of two turns.

6. Use a hexagon wrench to loosen the high-pressure valve.

7. Observe the copper pipe below, there will be air leaking out automatically, when the leakage becomes cool, quickly tighten the low-pressure screws.

8. Use a hexagonal wrench to tighten the high blind and pressure valves.

9. Put the two valve screws back and tighten them, and you're done.

The specific method steps for air conditioner exhaust are as follows:

1.Connect the internal and external machine pipelines.

2.Debug as shown and start venting.

3.Exhaust for about half an hour.

4.Observe the pressure gauge and prepare for the end.

5.Close with a hexagonal as shown in the diagram.

6.Dismantle, extract the table.

The method of exhausting an air conditioner depends on the type of air conditioner and the location where it is installed. Here are some common methods of air conditioner exhaust:

1.Window air conditioners: Window air conditioners usually have an exhaust pipe that can be vented outdoors through a window or wall.

2.Split Air Conditioner: Split Air Conditioner usually has one indoor unit and one outdoor unit. The indoor unit of the stool is connected to the room through the pipe, and the exhaust is discharged outdoor.

3.Air conditioners usually consist of an outdoor unit and an indoor unit. The indoor unit is connected to the outdoor unit through a pipe to exhaust the exhaust air to the outside.

4.Portable air conditioners: Portable air conditioners usually have an exhaust pipe that can be vented outdoors through a window or wall.

Regardless of the type of air conditioner, the exhaust pipe should be properly installed and maintained to ensure air circulation and safety.

Open the valve of the open liquid pipe, loosen the screws of the trachea connection on the outdoor unit, hear the obvious sound of deflation, and feel that your hand is a little cold, you can stop deflating and quickly re-tighten the connecting nut of the trachea. Note that there is gas ejection from the refrigerant pipe head, until there is a cold air ejection, and then all the valves at both ends of the pipe are opened, and the exhaust gas is simply inspected. For the inverter air conditioner, the vacuum pump should be used to empty the air conditioner, connect the high and low pressure pipes of the exhaust, connect the vacuum pump and the hose, start the power supply of the vacuum pump, vacuum the air conditioner, and remove the hose and turn off the vacuum pump after the vacuum is completed.

In short, no matter what kind of air conditioning emptying method, after completion, it is necessary to test the air conditioner to test the effect of air conditioning operation. When it is found that the air conditioner is not fully emptied, it is necessary to re-exhaust the air conditioner.
