After the entry into the Futian, the air temperature in Maanshan remained high, and many netizens called "this life is given by air conditioners." But do you know? If the installation is not properly used, the "cooling weapon" of air conditioners may also become a "killer."

In the past few days, a "famous media person suffocated and died because of the spontaneous combustion of air conditioners to release a lot of poison gas" caused concern. On July 20, the reporter learned in an interview that if the air conditioner is improperly installed and installed, there is a danger of spontaneous combustion. According to industry insiders, the weather is hot and the frequency of air conditioners is getting higher and higher. I hope that the general public will use air conditioners to enjoy the coolness while improving safety awareness and avoiding various safety accidents.

Air-conditioning spontaneous combustion for a variety of reasons

The air conditioner will also ignite spontaneously? The answer is yes.

"Air-conditioning self-ignition, mostly due to short-circuit and fire of wires, overload of electrical insulation caused by insulation materials, etc.." Ma Anshan Power Supply Company Marketing Department is responsible for Zou Lei told reporters that there are many reasons for air-conditioning fires, of which only air-conditioning electrical lines are on fire. A variety of possibilities.

Improper installation can also cause air conditioning to catch fire. Mr. Hu, the person in charge of the customer service station in the Maanshan area of ​​Gree Electric Appliances, said that when the air conditioner is installed, if it is close to the flammable objects such as curtains and placed in the morning sun, when the air conditioner is running for a long time, the temperature of the motor is too high, which will result in The internal insulation layer burned out, and leakage occurred and sparks appeared. In addition, indoor hanging machine or cabinet body, especially the air outlet, etc., if the covering is covered, the first will affect the use effect, and the second is that during the air conditioning cycle, the covering will wrap around the air conditioning motor bearing, resulting in motor load. Increase, overheating and catching fire. “After turning on the electric auxiliary heating function of the air conditioner in winter, if the flammable material is covered at the air outlet, it is more likely to cause the air conditioner to spontaneously ignite.”

"Excessive service" and internal line aging will also cause spontaneous combustion of air conditioners. Mr. Hu said that the service life of air-conditioner wall-hanging machines is generally about 10 years. If it is "overdue service", the lines inside the air-conditioner internal machine may be aging, which may cause leakage of electricity due to insulation damage. If the current is too large when the air conditioner is working, sparks may occur in a high temperature environment, which may cause spontaneous combustion.

Citizen safety awareness needs to be strengthened

Yesterday, the reporter saw in several districts in the urban area of ​​Maanshan that in the hot summer days, many residents were air-conditioned in their homes and office buildings. However, the reporter found in the interview that many people think that air-conditioning can be used, lack of air-conditioning safety and maintenance awareness, and it is not clear about the safety hazards of air-conditioning.

“Use it every year in summer and winter, and at most, clean the filter before use.” In the view of Ms. Chen, a resident of the mining community, as long as it can be cooled and heated, the air conditioner is operating normally and there is no need for maintenance and maintenance. . As for the precautions for safe use, Ms. Chen believes that when the door is out or not in use, the air conditioner power supply can be cut off. "There has been no attention in other areas." There are not many people who have the same ideas as Ms. Chen. As for the service life of air conditioners, most people think that "as long as they can be used normally, there is no need to replace them."

“Every year, we will launch the 'Free Service Month' event before the summer and winter to provide air conditioning services for the public.” Mr. Hu said, but from the situation of the activities in recent years, the citizens who have air conditioning maintenance needs still Not many, "This also reflects the public's awareness of the safe use and maintenance of air-conditioning is still weak."

You need to know these precautions when installing air conditioners.

How to eliminate the safety hazards of air conditioners and achieve "preventing problems before they happen?"

According to the professional introduction, the height, direction and position of the air conditioner installation must be conducive to air circulation and heat dissipation during installation, and pay attention to keep a certain distance from combustibles such as curtains. In addition, air conditioners must use dedicated power outlets and wiring, and cannot be used with lighting or other household appliances.

“The air conditioner must be equipped with a leakage protection switch to prevent fires caused by voltage fluctuations.” Zou Lei said that when using air conditioners, it should be operated under the supervision of people, and the air conditioner power should be cut off when going out. In addition, do not cut off or turn on the power of the air conditioner continuously for a short period of time. After powering off or unplugging the power plug, be sure to set the selector switch to the “stop” position. After turning on the power, press the startup step again.

When the air conditioner is running, avoid too close to other items, and do not cover the air conditioner. The air conditioner should be regularly maintained, and the condenser, evaporator, air filter and heat exchanger should be cleaned regularly to remove dust and prevent dust deposition from affecting heat dissipation. Mr. Hu said that for air conditioners that have been shut down for a long time, it is necessary to carry out inspection and maintenance before restarting. If there is no fault and then put into operation, it must not be “sick”.

"The average service life of air conditioners is about 10 years. The old air conditioners have been used for a long time. It is best for professionals to conduct inspections once a year." Mr. Hu reminded that over the years of use, air conditioners may not be completely striked, but due to various parts. The aging, wear, work efficiency, safety, etc. will be greatly reduced. "The air conditioner of 'overdue service' must be replaced in time."

Tips

How to self-check air conditioning at home?

It is recommended that users check the air conditioner regularly before the annual usage season.

External machine mounting bracket: The mounting bracket is exposed to the outdoors all the year round. Regularly check whether the mounting bracket and the expansion bolt are rusted every year, and whether the expansion bolt shows signs of loosening outward.

External machine wrap belt sheath: air conditioner used for many years, the strapping belt is easy to loose and aging, and the copper tube will be exposed to the air, which will affect the cooling and heating effect.

Indoor unit installation hanging board: The old wall faces the air conditioning hanging board's carrying capacity will be poor, especially in the case of water seepage or mold wall cracking, it is necessary to check whether the air conditioner inside machine is loose.

Power plug: The reed of the socket may be deformed or insufficient due to insertion and removal. Pay attention to check whether the contact between the air conditioner plug and the socket is reliable and there is any trace of heat.

Cleaning the air conditioner: Before the season of use, please clean the filter. For users such as evaporators and air conditioners, you can clean it yourself. You can ask professional maintenance personnel to clean it.
