Can the duct machine add liquid from the inside? Precautions for installation of air duct machine

This kind of air duct machine can add liquid from the inner machine, this is no problem, adding some appropriately will not have an effect, this can be.

The air duct should try to avoid adding liquid (refrigerant) from the internal machine, because it is easy to cause insufficient evaporation when adding refrigerant directly back to the compressor, resulting in liquid shock, and the compressor will reduce its life.

Of course, the skill of the air duct cannot be added from the inside, and the liquid can only be added after it needs to be opened from the outside.

In the case of the duct machine, the liquid cannot be added from the internal machine, but must be added from the outside machine.

It depends on whether there is a needle valve on the low-pressure pipeline between the suction port of the air conditioner compressor and the four-way reversing valve.

If there is a needle valve in this part, the refrigerant can be filled directly from this needle valve when the air conditioner heating mode is running; If there is no needle valve designed in this part, the air conditioner should be forced to run in refrigeration mode, and refrigerant should be injected from the needle valve on the low-pressure stop valve of the outdoor unit.

When filling the refrigerant, it should be ensured that the refrigerant is injected in the form of gaseous state to prevent the compressor from producing liquid shock.

Well, of course, the duct machine can be added from there, and the setting is completely OK, it depends on your technology or find their maintenance workers to help you add it, and their words are professional.

The external function can add page numbers from the inner machine, it should be possible, so it is interconnected, if you add armpits from this, the machine will wear out, it is smaller, and there will be a maintenance effect.

Friend, do you mainly look at where Jiayekou is Jiayekou? If it's internal, then it's machined from the inside, and if it's outside, it's machined from the outside.

The air duct machine cannot add liquid from the internal machine.

Generally, we may use low-pressure fluoride and static fluoride to fluoride air conditioners.

1. Turn on the air conditioner and add fluoride from the low pressure, when it is added, you can do it, and then observe the refrigeration effect of the air conditioner. If possible, the high pressure should not be exceeded.

2 When the air conditioner is deactivated, add fluoride from the place where it was added. When the system pressure reaches the appropriate 3 Let the air conditioner run for 30 minutes and do a careful inspection.

3.The correct way to add fluoride When adding fluoride, you must take it slowly, add a little and let the air conditioner run for about 10 minutes, and then measure the pressure and current.

When adding fluoride in winter, the four-way valve coil can be disconnected, and the indoor temperature sensing head can also be artificially made to reach a temperature that can be cooled to open the refrigeration. Sometimes it is also possible to let the air conditioner run in dehumidification mode, which does not have very high temperature requirements.

Generally speaking, it is possible, and it can be done from the inside, but it is generally a problem in the United States.

Can the duct machine add liquid from the inside? I think that science is very advanced now, and she can add liquid from the internal machine, which is more convenient.

The air duct machine cannot add refrigerant from the internal machine, and the refrigerant must be added at the external end.

The internal unit discharges air to the living room and returns air from the dining room, that is, the side exit and back return mode, so that the air can be circulated throughout the house.

You can also install the internal machine in the curtain on the balcony to come in, and the air will come out of the dining room and the side will go out. The location of the host on the balcony is small, and there is no small external machine, but only the bathroom, from the second bedroom to the corridor.

Of course, it's protective.

Can the duct machine add liquid from the inside? I think this duct machine can add liquid directly from the internal machine.

Duct machine man translated from Ruijia? Yes, it should be said that he also went to Chiayi from the inside of the machine, and he could go according to his instructions.

This should be a single page that can be made from the internal machine, and this should not be easy for him to penetrate, so this one should. Make him a little stronger.

The air duct function from the mainland should be about the same, but it depends on what kind of structure he is in.

This is not painful, and if you are going to add liquid like this, then it is very easy to cause the failure of the whole operating system.

That's right, this is according to what you said, it should be a good question for the bonus period.

This is a professional question, I don't dare to be casual, I think you can check it on the Internet and listen to what other netizens have to say. You can also ask a local professional to ask them for advice.

8. There is a technical problem that requires a special master to be able to know, so it is best to ask the person who has only used this machine.

The air duct machine cannot add liquid from the internal machine, and needs to be added from the inside.

Can the duct machine add liquid from the inside? If you don't know this, you can find a professional to come and show you.

Do you actually eat supper from the inside, this is not very clear, this professional question I think you should ask the professional, if you don't go to the Internet to check it out and understand the relevant knowledge.

Is it caused by your installation pipe being too long!

If it is the above situation, it is necessary to properly supplement the fiber chain freon, otherwise it is easy to burn the compressor Bo Zhixiang, and there is a relevant statement on the manual.

1. Be sure to communicate your ideas with the installer before installation.

2. Consider the installation location of the internal and external machines

Internal machine: 1Show your ceiling drawings.

If the air outlet of the machine is too far away from the air outlet of the ceiling, the blank space in the middle of the refrigeration is easy to have condensation, dripping on the ceiling, and the ceiling is easy to mold over time; 2.The position of the yin angle line should be left for the punching and hoisting machine, and the hole should be lower than the machine to facilitate drainage.

Outside machine: Try to put it in the seat reserved by the developer, so as not to affect the harmony of the neighborhood caused by the noise caused by the use in other places in the future. If the reserved seat is really unusable, try to find a seat that is not easy to affect the neighbors (the machine will vibrate and produce noise when it is running, which will affect sleep at night and study and work during the day.

The external unit must be fixed with expansion screws, so as not to be easily shaken downstairs (especially high-rise) when the external unit is swayed, and the external unit and pipeline will be seriously damaged.

What is a Duct Machine?

The air duct machine is the air duct air conditioner, the air conditioner is connected to the air duct to supply air to the room, the so-called high static pressure air duct is the air duct air conditioner used in the fan is a high static pressure fan, the air conditioning static pressure is equivalent to the residual pressure outside the machine, which is a parameter of the air conditioning air supply capacity, the greater the static pressure, the longer the air supply head. Because the air supply of the air duct type air conditioner needs to pass through the air duct, the loss of air pressure will be increased during the air supply process, and if the high static pressure fan is not used, the air sent to the room will be very small.

According to the characteristics of different types of products, the advantages and disadvantages of air duct machine compared with cabinet machine are:

Advantages: It does not occupy the space of room difference sensitive internal leakage, the hidden virtual search branch is beautiful, and the capacity of the air duct can be from 1 to 10 horses, with a large range and a wide applicable area.

Cons: Requires a high ceiling height, or takes up a certain amount of room height space.

It is necessary to install special air supply and return outlets.

Repair is difficult.

Yes, when you buy or install it, you can first ask the sales person that you need the function of ventilation, and you can do it.

The fan coil unit cannot be ventilated, if you want to ventilate, you can add a new fan, or a full heat exchanger.

Of course it can, as long as the air conditioner needs this function, it can have.

No, the air conditioner can only exhaust and cannot intake.

You can use a negative pressure fan.

Naturally, it is drained by its own gravity or forced by a condensate drain pump.

At present, most of the air duct air supply air conditioning units rely on the gravity of the condensate itself to achieve condensate removal, and a relatively small number of air duct units are designed and installed with condensate drainage pumps, and the drainage pumps work to drain the condensate when the condensate accumulates to a certain extent in the water receiving tray.
