How to automatically relieve pressure of the air conditioner

There is no need for manual pressure relief, when the compressor is shut down, there is no role of the compressor, the high and low pressure of the system will eventually be close to each other, when the appropriate value is reached, the compressor high pressure switch will automatically jump open, and the system will run again, but do not unplug the power switch and shut down during this time.

The high-voltage protection is through a pressure protection switch, after the switch is activated, the relevant circuit is broken, the compressor is shut down, and after the press is stopped, the refrigerant in the system will be automatically balanced through the capillary, and there is no need for manual pressure relief.

It is recommended to clean the condenser first, and if the fault is still found, find out the cause.

But if you ask like this, it is estimated that you are not eating in vain, and you should have asked until there is no way to repair it. Then short-circuit its high-pressure protection to see if the compressor will overheat and shut down, if it is non-stop, it should be said that there is a problem with the high-pressure pressure switch, it can be replaced, you can ignore it, scrap is, if it is a compressor, it will be troublesome for thermal protection!

The basic maintenance does not need to be told to you, the fault is difficult to solve, but you can skip the method You can add a pressure opening valve between the high pressure and low pressure of the compressor (this method is common in multi-online automatic pressure relief) As for how many kg of the valve, you have to take the pressure yourself, see what the original pressure is until the compressor stops working. I don't need me to teach you anything else! )

1.The first thing we have to do is the refrigerant, which is a necessary step. Before disassembling the machine, we start the air conditioner and then turn it to the cooling state.

After 5-10 minutes of operation, its cooling state can return to normal, and we can start to do it. 2.Unscrew the lid on the liquid and gas pipe interfaces of the external machine.

Then close the shut-off valve of the high-pressure pipe and wait a minute to see if there is any condensation outside the pipe. Then immediately close the shut-off valve of the low-pressure pipeline, and at the same time quickly close it, and unplug the power supply. 3.

Tighten the hard hat with a wrench. Until the refrigerant** work is complete. We can also use the force start button on the indoor unit to start the machine.

Doing so will save you the hassle of moving away. 4.After the refrigerant**, you can start disassembling the indoor unit.

The first thing to do is to use a wrench to unscrew the connecting lock nut of the indoor unit, and then take out the sealed sodium screw after Zheng erected, and use it to protect the silk thread of the indoor connecting joint. This is also done to prevent damage to the joints during handling. 5.

Then, use the cross to remove the control line. Pay attention to marking when disassembling to avoid connecting the wrong wire during installation. Generally, the internal units are hung more firmly, and it will be more difficult to disassemble.

When we finish dismantling, we can remove the hanging board and put it on the flat ground for correction. When disassembling the outdoor unit, it is best to hang it with a rope to avoid vibration and bumping. Pay attention to safety when disassembling.

After the crab is ready, the four ports of the connecting pipe should be sealed with four plugs to prevent dust and moisture from entering.

The key to disassembling and assembling the air conditioner is to collect fluoride, as long as you follow the steps to solve it yourself.

Procedure. 1: Set the remote control to cooling mode to turn on the air conditioner.

2: Check whether the indoor unit is running normally.

State 3: Whether the outdoor compressor starts normally.

Dismantle the air conditioner to collect fluoride.

Fluoride collection in the refrigerated state:

1. Close the high-pressure valve tightly. "That is, the thin pipe".

2. After the isopress works for a few more minutes for 1-2 minutes. Then close the valve of the low-pressure pipe "thick pipe" tightly.

3. Then turn off the machine and disassemble the pipes and wires.

4. Disassemble the machine.

After the machine is moved, put the fluorine out.

1. Connect two copper pipes, the small one is a high-pressure pipe, and the joint is tightened first.

2. The big one is a low-pressure pipe of the sail bird, and it is tightened and loosened a little after being connected, because the air needs to be exhausted.

3. Next, open the valve on the high-pressure pipe, and hear the gas being discharged from the untightened interface of the high-pressure pipe.

4. When you feel all the air in the tube when you feel all the air in the tube being discharged with your hands, tighten the joint nut on the low-pressure tube (about 5 seconds) until there is no gas leakage.

5. Check whether there is any leakage in the interface.

6. Open all the valves on the high-pressure pipe and the low-pressure pipe.

7. Start up and run.
