Sitting on the floor air conditioners are mostly non-compliant or deadly killers

When summer is here, air conditioners have become a favorite "weapon" for the public, but if installed and used improperly, they can also become a deadly "killer." On June 1, the owner of a hairdressing shop in Rong'an County, Nanning, Guangxi, was electrocuted to death when he stepped on the outside of the air conditioner while chatting outside the shop.

"Sitting on the floor" air conditioners are mostly non-compliant or deadly "killers"

　　 There are not a lot of external air conditioners

　　 In the past few days, when the reporter visited Yuejin Road, Yaru Road, Beique Road, and the city center in Liuzhou City, he found that there are more phenomena of “sitting on the ground" outside the air conditioner, and shops along the street are more common. In these road sections, most of the outdoor air conditioners at the entrance of the first floor shops are directly "sitting on the ground", most have simple protective facilities, and some do not have any protective devices, so that passing citizens are "at your fingertips."

"Every time you pass the shops along the street, hot wind blows through your legs, and there is still a risk of electric leakage from the'sitting on the ground' external machine. Why don't the businesses install the air conditioner outside higher?" Ms. Zhang, who lives on Yaru Road, said , I hope that the air-conditioning plug-in units of shops can be set more reasonable and standardized.

Why not install the external air conditioner on the wall? Ms. Wang, the owner of a clothing store in the city center, told reporters that she is a store along the street, and she has no extra space at all. It can only be placed at the door; if the external air conditioner is installed at a high Place, it will hinder the placement of billboards in the store.

　　 For some rented facades, the outdoor unit of the air conditioner is directly "sitting on the ground" for easy transportation, which also saves the cost of next disassembly and assembly.

　　Outside the machine installed roadside is not up to standard

According to the 2013 edition of the National Air Conditioning Installation Standards issued by the National Bureau of Quality and Technical Supervision, the distance between the bottom of the mounting frame and the ground for air conditioners installed along the buildings on both sides of the road should be greater than 2.5 meters, and the public sidewalk should not be occupied; The aisles, corridors, exits and other common places shall not be installed with outdoor air-conditioning units; the outdoor air-conditioning units should be as far away as possible from neighboring doors and windows and green plants, and the distance from each other's doors and windows should not be less than 3 meters.

　　 However, the reporter found that there are not many people who can install according to the specifications. Most of the ground-mounted air conditioners of the shops and residents on the first floor are mostly installed on the ground, and the distance from the ground has not reached more than 2.5 meters.

Mr. Wei, an after-sales technician of an air-conditioning company in Liuzhou, said that the national standards cannot actually be implemented in place. “Some users are unwilling to hang the external unit on the wall because of cost savings." For this, there is no specific management requirement, so it appears The irregular phenomenon.

However, the reporter's investigation found that some installation workers know little about the installation standards stipulated by the state, and some also said that they have not heard the relevant requirements for air-conditioning installation, and said that it is common for air-conditioners to be installed on the ground, 2.5 meters above the ground. "No need".

　　Leakage is mostly caused by not grounding

　　 Why does the external unit of the air conditioner leak? Wei said that the leakage of the air conditioner's external unit was mainly due to incorrect wiring, aging, cracking of the live wire insulation, and rats biting the wires.

　　 Wei explained that the safety voltage of the human body is 36 volts, which means that the external unit of the air conditioner is very safe without starting. However, all air conditioners are grounded, live, and neutral, and z* is dangerous. If the live wire touches the casing of the external air conditioner, and the circuit breaker cannot cut off the power, the casing is very dangerous if it is charged. Many electric shock accidents are likely to be caused by the live wire hitting the outer casing of the air conditioner.

"To avoid air-conditioning leakage and injury, the key is to form an effective grounding. The air-conditioning socket must be a three-hole socket equipped with a ground wire to ensure that the air-conditioner is effectively grounded through the air-conditioning socket; if the grounding is not complete or the grounding is incomplete, there may be a risk of electric shock. "Mr. Wei said.

　　 In addition, citizens can also check the internal wiring of the air conditioner. If the wiring is tight or the wire ends are more exposed, the possibility of leakage will be greater. If you install a leakage protection switch for the air conditioner, it can also effectively avoid the accident of leakage and injury.

　　We reminded that citizens should not approach the external unit of the air conditioner when walking along the street side store. First, the hot air generated by the outdoor unit may burn people, and the other is that the outdoor unit will inevitably generate current, which may pose a safety hazard. In addition, the service life of a general air conditioner is about 10 years. If the air conditioner is used for an extended period of time, it is easy to leak electricity, and in serious cases, there will be a fire or short circuit from the live line. Therefore, citizens should check household appliances regularly, and it is best not to use them for an extended period of time.
