The air conditioner shows lightning protection and riot protection

- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

If you still don't understand, it is recommended that you go to [Air Conditioning Failure**Net] to see more maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you a smooth job search, a smooth work, and ———a happy life

Is it lightning storm protection, or lightning protection is also explosion-proof?

It's split into two. Clause.

1. What are you going to do from your standpoint? Clause.

Second, from the perspective of security, what do you think should be done? I think you already know the answer and you've decided how to do it, right?

It has to be changed to another place, and even if it is marked, it will be a safety hazard in the future.

It's best to seal this air conditioning hole and make another one.

Yes, but it is very weak, otherwise the air conditioner will not be broken so much during the thunderstorm season.

It is generally available on the circuit board of the air conditioner.

Manufacturers with core technology have this function.

Just like the wired signal line of the TV, in a thunderstorm, the outdoor unit of the air conditioner is also the culprit of "thunder". There are several factors to consider when it comes to lightning protection of air conditioners:

First of all, the outdoor unit of the air conditioner should consider the lead problem with the building when installing; Secondly, shield the indoor air-conditioning host to prevent lightning current intrusion. To be on the safe side, it is still recommended to turn off the air conditioner and cut off the power supply during a thunderstorm.

Outdoor chassis will rarely be struck by lightning, or pay attention to the lightning protection of the indoor power cord, it is better to install a power surge protector at the power cord entrance line of your home.

The outdoor unit of an air conditioner is rarely directly hit by lightning, and if lightning is induced, the indoor unit will often be damaged first.

Hehe, you're lucky with this question, so I can see it.

I run an Internet café, and I have encountered thunder during the summer vacation every year.

The most vulnerable to breakage is the network card Mao Land Game Main Edition First of all, you first see if you can still open the machine.

If the boot is normal, it means that the hardware is fine.

I am checking if I can access the Internet.

If you can't access the Internet, check the hair problem first, that is the network card, just change the network card.

If only Ray were close to you.

Hehe, I guess the contents inside can burn out.

Try not to surf the Internet during thunderstorming.

Take off the network cable, take off the network cable on the hair, and turn off the power to turn it off.

Without this effect, it will be turned off when it rains and the weather is not hot. It is better to cut off the power.

Yes, yes, that is, try not to install the air conditioner on the roof as well!

Generally, the grounding wire of the machine will pass a part of the surplus electricity to the ground.

But Mitsubishi Heavy Industries is not as good as Mitsubishi Electric, these two brands are called Mitsubishi, one is engaged in heavy industry, the other is civilian-oriented, try to buy Mitsubishi Electric, things must be heavy work meticulous and professional.

You get what you pay for, some money can be saved, and the money for electrical appliances is discounted if you save a little money.

Mitsubishi's power board has a surge-proof device, which can prevent overvoltage from power fluctuations.

If lightning protection, or hand over to the power supply and distribution system of the power arrester, very professional SPD, building lightning protection by lightning rods, lightning wires, lightning belts, down wires to complete.

As long as the air conditioner is connected to the power grounding wire, the outdoor unit should not be installed at the highest part of the building.

Are you talking about air conditioners or home air conditioners?

If it is an air conditioner, it does not have lightning protection, and it needs to be equipped with lightning protection devices.

The most important thing is grounding, if there is no grounding or not done well, no matter how good the air conditioning and lightning protection devices are, it is useless.

Generally, 14D561K, 14D621K, and 14D681K are used, and these three pressure-sensitive models are basically used by domestic manufacturers.

1. The current air conditioning varistor must use an explosion-proof varistor, which is stipulated in the design manual: the controller is not allowed to use a non-explosion-proof varistor.

2. The varistor on the air conditioning control board is distinguished by the design function, and the lightning protection varistor you asked generally refers to the use of varistor between the power line and the earth, sometimes the voltage between the line and the ground rises due to poor grounding, so the varistor with a higher nominal voltage is usually used than the use of the line and the line. Varistors must be considered in circuits to be able to withstand the effects of lightning overvoltages, operating overvoltages, and transient power frequency overvoltages. Lightning varistors are generally used in conjunction with fuses or discharge tubes in the first stage of the power supply section.

3. Universal design, the lightning protection varistor of the control board of the air conditioner generally uses Galanz air conditioner 14K471 14K621 (explosion-proof), Gree 14K621, Guangdong Changhong 14K561, Haier 10K561

Yes, it should be connected to the structural reinforcement of the building, because the equipment is connected to the interior part, which should prevent electric shock to the user and protect other low-voltage equipment.

Theoretically, it is certain that you must do lightning protection grounding regardless of the height of your floor, but if it is a household appliance, I suggest that you do not need the lightning protection grounding of the air conditioner, generally speaking, as long as the air conditioner is not on the roof of the building and the second is on the side of the building, the probability of being struck by lightning is very small. Satellite receivers are a must.

The pressure resistance value of the air conditioner is much higher, and it doesn't matter if the induction lightning is not grounded, the key is that after reaching a certain height, the side lightning protection should be considered, and the lightning protection specification requires more than 30 meters to do the side lightning protection.
