[Air-conditioning explosion, men from the 3rd floor to the 2nd floor, air-conditioning operation security alert]
Release date:[2018/12/17] Is reading[823]次

Air-conditioning installation and maintenance workers have always been a controversial profession, and laymen say it is hard, but high-paying. However, in fact, the installation and maintenance of air-conditioning is a high-risk type of work, because the higher the building is, the more difficult the environment for installing the air-conditioner is, the more and more the safety of the workers is not guaranteed, and the high-altitude falling incidents occur frequently. In addition to high-altitude safety, accidents involving air-conditioning explosions have occurred from time to time.


Recently, a man in Zhongshan, Guangdong Province repaired the air conditioner himself. He just opened the outer casing, and the air conditioner outside the machine suddenly exploded. The huge impact did not get the man from the 3rd floor to get the platform on the 2nd floor.


Why does the air conditioner explode? The maintenance personnel said that the compressor in the air conditioner had failed. The split type air conditioner is composed of an indoor unit and an outdoor unit. The indoor unit mainly has a heat exchanger component, a fan, a shut-off valve and an electric control component, and the outdoor unit mainly includes a compressor, a fan and the like. The compressor is the core component of the air conditioner, which is equivalent to the heart of the human body. The compressor is filled with refrigerant freon, which is often referred to as snow. Some maintenance personnel said that when adding snow, be sure to be vigilant!


Most of the current household air conditioners are frequency conversion models. The refrigerant used is R22, R410a or R32, especially R32 refrigerant. It is easy to explode when exposed to open flame. The requirements are quite strict: no open flame is allowed within 5 meters. ! In addition, the air-conditioner compressor has two valves, high and low pressure. If the installation is negligent, only one valve is opened, and the boot is prone to explosion. There is also a case where the copper pipe is welded or cracked during installation or repair, causing the refrigerant to leak and explode in the event of an open flame.


To sum up, there are two points that cause the air conditioner to explode: the refrigerant directly encounters the open flame and the high and low pressure valves are not opened. Air-conditioning installation and maintenance must be determined by regular professional personnel, air-conditioning installation masters must pay attention to safety when working.
