The air conditioner also has a service life, it is best not to exceed 10 years

Most of the air conditioners in the accident are old products that are "overdue" or even "with illness"

The air conditioner also has a service life, it is best not to exceed 10 years

This summer, it is extremely hot, "My life is given by the air conditioner" is not exaggerated. However, while many people rely on the air conditioner to renew their lives, some air conditioners that "use it with it" also surprised people. Recently, the number of reports on air -conditioning safety accidents on the media has increased significantly. The reporters sorted out and found that many of these air conditioners were "over -service" or even "on -the -job" old air conditioners. Some air conditioners have even used for 20 years! Many people may not know that in fact, even if the air conditioner is not bad, there is a life span. It is quite dangerous to force the air conditioner to "over -service"!

In this regard, some professionals told reporters that normal air conditioners are not afraid of use, and there will be no problems even if it continues to operate from day to night. The most likely reason for air conditioning to fire is the old fault of the equipment, so as to be short circuit at high temperatures at high temperature. Failure is mainly.

Self -ignition of air conditioning occur in more places

Some air conditioners have been used for 20 years

With the hottest period of the year, coupled with rare high temperatures in many regions of this year, air -conditioning accidents in various places have also increased significantly recently. In just one or two months, the media reported that there were many domestic air -conditioning fire accidents--

On July 19, a fire broke out in a residential building in Changsha, Hunan.

In the early morning of July 16, a resident of a resident of Chaoyang Village, Qiaos Street, Yuhang District, Hangzhou City caught fire. According to a preliminary understanding, the fire building was a building with a 5 -storey brick -structured structure. The burning substance was an air -conditioned aircraft. At present, the cause of the fire is still under investigation.

On July 12, a fire broke out in a residential house in Wuhan, Hubei, and the fire was caused by the short circuit of the air -conditioned air conditioner.

On July 6, a fire broke out in a residential house in Gongshu District, Hangzhou.

On the afternoon of June 27, the air -conditioning of the first community in the West Lake in Hangzhou caught fire.

On June 20, the fourth floor of Xixiqiao, Xingtian Street, Xingning City, Guangdong, an air -conditioned aircraft was on fire and was burned with only one residual shell.

It is understood that among these air conditioners that occur in the accident, a considerable part of the old air conditioners with too long periods of use, and some fire air conditioners have even been used for 20 years.

reason

The air conditioner is also afraid of heat

High temperature days will also "heat stroke"

"Actually, the air conditioner is also afraid of heat. If Tianda will also be" heat stroke 'strike! "Zhao Binghua, the director of Suning Tesco helpers, introduced in an interview with reporters that according to the current manufacturing standards, when the air conditioner outdoor unit reaches 43 degrees Celsius, the air -conditioning outdoor unit reaches 43 degrees Celsius. The refrigeration effect will weaken. At this time, the user can already feel that the air conditioner is not so useful. Often at this time, some users set the temperature to be lower. The operation of the air conditioner itself will dissipate heat, which will cause the air -conditioning environment temperature to become higher and higher. In order to ensure the safe operation, there will be a thermal protection device in the air conditioner. Usually, when the environmental temperature of the outdoor unit reaches 48 degrees Celsius, the air conditioner will automatically shut down to stop operation.

Zhao Binghua emphasized that this shutdown is the self -protection measure of air conditioning. It is to use the equipment without failure. Some users do not understand this self -protection function. As soon as the air conditioner stops, it will be turned on and found that the air conditioner is broken if it is unable to run. In fact, as long as the temperature of the outdoor unit drops for a while, the air conditioner can be turned on again.

investigation

Why does the old air conditioner

Fire accidents?

For air conditioners that are also afraid of heat, once they cannot heat dissipation, they may cause failure or even accidents. Zhao Binghua analyzed several reasons for air conditioning fire to reporters, and was mainly concentrated on the air conditioners running with old or even illness.

From the analysis of the case, the main reason for the fire of air conditioning is that the temperature is overheating and caused a short circuit. When the air conditioner is running, the wires and electrical control systems will heat up due to the current of the current. Under high temperature, if the insulation effect is not good, a short circuit will cause a fire between the line and the wire. This situation mainly appears on the old air conditioner. As we all know, the air -conditioning outdoor unit is easy to equipment aging when it is hung on the outdoor wind. Once an insulation, there may be short circuits, especially at high temperatures.

In addition, the internal capacitance capacity of the long year will also change, thereby increasing the load of the compressor. Due to the increase in current, the temperature increases, which can also cause safety accidents.

In addition, there is a situation that the heat protection of the air conditioner fails, and the temperature will not stop, which will cause the temperature to become higher and prone to fire accidents.

remind

Let the outdoor unit be more breathless

Can reduce failure

Since the air conditioner is afraid of heat, it will make it as much as possible to ventilate and heat dissipation, which will help the air conditioner safely. According to the specification, the outdoor unit of the air conditioner should be placed in a three -sided ventilated environment, which is conducive to air conditioning heat dissipation. However, during the interview, the reporter found that the design of the air -conditioning bit of the architecture itself, or the user himself, sometimes the air -conditioning outdoor unit was intentionally obstructed, leaving only a very small breath to connect to the outside world. This too closed design is not conducive to air -conditioning outdoor unit heat dissipation, and it is easy to increase the temperature in the machine rapidly.

In addition, it should be reminded that even if the standard air conditioner is installed, the outdoor machine is leaning against the wall. Because the corner is easy to accumulate dust, fallen leaves and other debris, the air conditioner outdoor unit is the back of the back, which is easy to suck the debris into the back. The chassis is adsorbed on the condenser, and it will also seriously affect the heat dissipation. And some dry dust flies are prone to safety accidents at high temperatures. Therefore, some professionals remind that when the air conditioners are used, they should often check whether there are debris inhaled outdoor. Especially when the catkins and leaves are used to use the air conditioner, the debris should be cleaned regularly. focus on

The safe use of air conditioning is ten years

The reporter learned that although my country does not have a unified mandatory standard for the use of home appliances, in fact, industry associations and manufacturers have recommended years of useful use of home appliances including air conditioners. In 2020, the China Household Electric Association has successively formulated a series of group standards for the "Household Electrical Electric Safety Use Latest" series of groups to define the safe use of common appliances. Clothing machines, gas stoves and range hoods are eight years. In this regard, some professionals said that because the use of air conditioners in different regions and even different families in my country is largely different. For example, the air conditioners in the northern region may only be used for one or two months in one year, and the southern region may use five or six a year to use five or six years. Month, so users can flexibly adjust their usage years according to their own use. But in any case, there is a large safety hazard in the use of an air conditioner for 20 years. At this time, even if the air conditioner can run normally, it is best to replace it.

At present, many consumers are still holding the psychology of "unavailable to change" by home appliances, which leads to a large number of home appliances that have more than 10 years or even longer. "In fact, people are not having no money but not conscious for replacing home appliances." According to people from the China Home Electric Association, according to the calculation data of 2020, about 180 million home appliances in my country have reached a safe period of use, of which the washing machine exceeded more than more 37 million units, more than 52 million air conditioners, more than 58 million refrigerators, more than 18 million electric water heater, and 14 million range hoods.

In fact, although these domestic appliances that exceed years can still be used, the performance has been significantly declining, and energy consumption such as water, electricity, and gas will also be significantly improved. More importantly, the longer the service life of home appliances, the greater the potential safety hazards.

In July of this year, my country announced that it would implement "replacing the new with the old" and "home appliances to the countryside" nationwide, and provided funding and policy support in conditional areas. Relevant sources of the China Household Electric Association said that this is actually a good opportunity to update many of the appliances that exceed the useful life but still use. Taking home appliances of rural families as an example, many products are still products when they went to the countryside in the last round of home appliances. At present, they have reached the replacement period. It can be replaced in time with a new round of subsidy policy to ensure the performance and safety of use. (Reporter Zhang Qin)
