Air-conditioning brackets have repeatedly become "air hidden dangers" Who should be responsible for "hidden altitudes"?

As temperatures have risen and air-conditioning has been used again, many air-conditioner outdoor units have been left in disrepair and become hidden dangers to pedestrians. Consumers’ rights organizations in 21 cities including Shanghai, Beijing, Tianjin, and Chongqing jointly issued consumer warnings yesterday. Watch out for support for overage service, causing air-conditioner outdoor units to fall and hurt and become a hidden danger in high-altitude protection.

The reporter learned from the Municipal Consumer Protection Committee that the current market for air-conditioned stents consists mainly of ordinary angle steels, galvanized steel sheets, galvanized steel sheets, or stainless steel materials. The first two kinds of rust prevention capabilities are generally safe. The period of safe use is five years. 10 years; the latter two have strong anti-rust capabilities and the safe use period is about 10 to 15 years. The peak of the first wave of air-conditioning installations in this city was in the mid to late 1990s. Even those brackets with stronger rust-prevention performance have long exceeded the deadline for safe use, and scaffolding that uses non-standard steel or scrap materials has been overwhelmed. However, most consumers are not concerned about this. Even if they find that the stent is rusted, they rarely realize the danger, and they do not expect to maintain or replace it.

According to Tang Jiansheng, director of the Law and Research Department of the Municipal Consumer Protection Committee, the user will be held liable for any damage caused by the fall of the air-conditioning outdoor unit bracket. According to Article 85 of the Tort Liability Act of the People's Republic of China, buildings, structures or other facilities and their shelving and hanging objects fall off and fall, causing damage to others. All persons, managers or users cannot prove that they are not at fault. Should bear tort liability; owner, manager or user compensation, if there are other responsible persons, have the right to recover from other responsible persons.

In addition, although the problem of air-conditioner outdoor unit brackets is prominent, at present, there is no corresponding and uniform quality standard in China. At present, when consumers newly install or update air-conditioner outdoor unit brackets, reference may be made to the “Specifications for Mounting Brackets for Outdoor Units for Air Conditioners” issued by China Household Appliance Service and Maintenance Association on April 19 this year. This is the first industry standard that focuses on the safety of air-conditioned racks. .

After the big heat has been reached, the demand for air-conditioning installations has also surged. However, due to the lack of installation standards and follow-up maintenance standards for air-conditioner outdoor unit brackets, many residents began to worry: if the brackets are aging, are there any hidden dangers of rust breaking?

Who should be responsible for the maintenance of the air-conditioner outdoor unit bracket for "wind and sun"? People in the industry believe that because of the variety of materials used in the stents and their different service lives, it is advisable that air-conditioning production and sales companies establish a tracking system and replace the stents after they reach a certain number of years.

Air-conditioning brackets repeatedly become "air hidden dangers"

“Our home air conditioning bracket has been for eight years, do not know if it will suddenly fall ah?” “Air conditioning outside the machine has been broken once, brackets do not have to change with it?” ... ... In the near future, due to air-conditioning bracket falling accident frequency Out of the house, people with "old brackets" at home are worried.

Not long ago, when an air-conditioning repairman was working in a residential area in northern Shanghai, the air-conditioning bracket at the foot suddenly broke and fell from the third floor and died on the spot.

The problem of aging of many old residential building air conditioner stands is quite prominent. Pingjiang Building, located at No. 25 Pingjiang Road, is a 23-year-old building. Looking along the outer wall of this 20-story building, many air-conditioned outdoor units are rusted.

The residents of the neighborhood said: "With more than ten years of support, I never thought that I would like to repair and renovate the problem. I recently discovered that it was an accident. We have already installed a new one on the basis of the old support. The stand for reinforcement."

The property personnel of Pingjiang Community introduced that many outdoor air-conditioner racks in the residential area had less than ten years of installation time. Few residents in the area usually requested to inspect the racks. However, the residents who recently came to consult and request inspections have increased suddenly, and they have not. The stents of a few residents were seriously eroded and needed to be replaced.

It is reported that in the mid to late 1990s, air conditioning began to be popularized in the home, and many air-conditioner outdoor unit mounts at that time had exceeded the useful life.

In recent years, stent fracture accidents have begun frequently in various parts of the country. In December 2011, Zhang, an air-conditioning repair worker in Nanjing, fixed the seat belt to an air-conditioning outdoor unit during the maintenance of the air-conditioner, and fell down from the second floor due to the severe corrosion of the air-conditioning bracket. , resulting in a fracture of the right leg; in April 2012, when Haikou citizen Peng walked on the sidewalk, the air-conditioning outdoor unit on the external wall of the 7th floor of a residential building suddenly fell just 20 centimeters behind him...

Why is the "over-commissioned" stent unreasonable?

Analysis of the industry, air-conditioning bracket is a "gray area" of installation and maintenance, on the one hand there is no installation standard, on the other hand there is no mandatory maintenance regulations.

Shanghai Shenhua Environmental Protection Machinery Industry and Trade Co., Ltd. is an air-conditioning installation and maintenance outsourcing company. Master Xu, a maintenance engineer, told reporters that one of the more common bracket materials on the market is stainless steel and the other is externally plated stainless steel. In contrast, the former is lighter and stronger, and less likely to rust. As for the installation method, there are also two kinds of welding and riveting screws, and there is no fixed standard.

Ren Chaoying, a member of the Shanghai Refrigeration Association and a senior engineer, believes that air conditioners are generally manufactured by manufacturers and then sold by merchants. Businesses often outsource the installation of brackets to other companies, thus gradually forming a scaffold for production by third-party companies. And the installation situation. However, due to the lack of standards for the supervision of stents, manufacturers do not assume obligations for stents, which leads to difficulties in accountability.

For the service life of air-conditioned racks, are there any mandatory regulations and standards?

In April 2012, the China Household Electrical Appliance Service and Maintenance Association organized and drafted the “Technical Requirements and Installation of Installation Criteria for Outdoor Units for Home Air Conditioners”, and stipulated the technical requirements and test, inspection, and installation methods for the outdoor unit mounting bracket for home air conditioners.

The provisions for the safe use period are: "The safe use period of the installation bracket is not lower than the safe use period of the air conditioner."

The reporter called the Shanghai home appliance service center. The staff responsible for maintenance said that the life span of the air-conditioning bracket is generally 6 to 7 years. It is best to replace the over-age bracket, but since it is not included in the air-conditioning warranty, installation and replacement need to be registered, the price is about 250 yuan.

Who is responsible for "airborne hidden dangers"?

According to statistics, in 2011, the domestic sales of air conditioners in the rooms was about 50 million units. According to each air conditioner with a pair of mounting brackets, the huge market for air-conditioning installation brackets has exposed the lack of maintenance.

Experts believe that consumers should not pay for the accident of air-conditioning brackets. First of all, due to the variety of materials used in the current racks, the service life varies, and it is best to standardize the installation process. If it is difficult to unify standards, it is better for companies to establish tracking systems and take the initiative to remind consumers.

"The bracket is an air-conditioning component that should be provided and held responsible by the manufacturer and bundled with the product." Ren Chaoying said that even if the manufacturer provides stents that are purchased separately or provided by the contractor, the quality supervision department and related technical departments should also require the use of the plant's shelf life, and the manufacturer should be responsible for the safety of the stent during this period. . Once the corresponding number of years has passed, it assumes the duty of warning and promptly reminds the user to replace it as needed.

He also suggested that because the residents do not have the ability to replace their stands on the one hand, and on the other hand they have a mentality that is in line with the status quo, it is difficult to truly realize potential hidden dangers. Therefore, community streets should also conduct corresponding investigations and warnings.

It is reported that Japan and other countries have stipulated that air conditioners are not allowed to be hung outside. Instead, a place dedicated to the placement of air conditioners must be provided in the balcony.
