Air-conditioning causes and solutions

Recently, as the weather continues to rise, reports of accidents involving household appliances caught fire. Among them, air-conditioning is the most frequently occurring fire. With the arrival of the air conditioning season, the frequency of use of air conditioners has begun to rise sharply. It is understood that for air-conditioning products, the most common problem with safe use is "fire," then what is the cause of the air-conditioning's fire? How can we prevent such things from happening? After reading the following article, you will know that, and quickly follow it. Let's go!

What causes the air conditioning fire ?

1. When the air conditioner is energized immediately after the power is turned off, the internal pressure of the compressor is very large, making it difficult to start the motor and causing a large current to cause the circuit to catch fire.

2. The electric heating and cooling type air conditioner suddenly shuts down or powers down when it is heating, the electric heating wire and the fan motor cut off at the same time or the fan fails, and the residual heat of the electric heating element accumulates, so that the ambient temperature rises, causing a fire.

3, the capacitor heat, moisture, leakage current increases, the insulation performance decreases, resulting in a breakdown failure, and then ignited the combustible material inside the combustion liner caused by the fire.

4. Axial flow or centrifugal fans are stuck due to mechanical failure and the temperature of the fan motor rises, resulting in overheated short circuit and fire.

5. When installing, connect the air conditioner directly to the power circuit with no fuse.

How to prevent summer air conditioning from catching fire ?

1. The best direction for installing air conditioners is to the north, followed by the east. The air conditioner should not be installed above the door, because it will speed up the inflow of hot air when the door is opened. The air conditioner can be installed facing the door so that the indoor air pressure resists the influx of hot outdoor air.

2. The height, direction and position of the air-conditioner installation must be conducive to air circulation and heat dissipation, and attention should be paid to maintain a certain distance from curtains and other combustibles. When the air conditioner is in operation, avoid getting too close to other items.

3. The power plug should be unplugged when the power is suddenly cut off. Wait for a few minutes after turning on the power and then turn on the power. Air conditioners must use special power outlets and lines, and they must not be used with lighting or other household appliances. Wire carrying capacity and meter capacity should be sufficient, plug and electrical components should be close contact.

4. The air conditioner must be equipped with a one-time fuse protector to prevent the temperature rise caused by the breakdown of the capacitor and cause a fire. It is required that the fuse capacity should be appropriate and wire and copper wire should not be used instead.

5, the air conditioner should be regularly maintained, regular cleaning of the condenser, evaporator, filter, heat exchanger, wipe dust, prevent radiator plug, avoid fire hazards.

Fireside things :

At 12 o'clock on the afternoon of June 23, the air-conditioner of a resident of No.2 Yongfu Street, Hengmen Primary School, Nanlang Town caught fire, and the Nanlang fire squadron quickly dispatched. At the same time, the residents of the Nanlang fire-fighting squadron were guided to self-rescue and extinguish the fire. After a quick and effective disposal by residents, the fire did not occur. Serious consequences.

On the way to the site, the squadron’s instructor informed the residents by telephone and learned that the owner’s home was burning with air-conditioning and the fire was large and there was a tendency to spread to the interior. According to the mastery of the situation, the firefighters asked the residents to cut off the power supply in the home and extinguish them with a fire extinguisher. Less than five minutes later, the firefighters again received a phone call saying "the fire had been extinguished." After the firefighter arrived at the scene, he helped the head of household remove the scorched air-conditioner and check the scene to confirm the possibility of no re-ignition.

China Rescue Equipment Network reminds that electric appliances such as air conditioners, refrigerators, fans, and transformers, which have a high usage rate in the summer, should not be used continuously for a long time. To be on the safe side, it is best to check the electrical wiring of home appliances, especially appliances that have a relatively long service life. , Please take care of maintenance personnel to avoid the aging of the wire. If an appliance catches fire, it must not be splashed with water. It should be withdrawn to a safe place and alarmed.
