Recently, a well-known media person passed away at home. According to police investigations, the cause of his death was due to spontaneous combustion of air conditioners and the release of a large amount of harmful gases. The death of young life makes people sigh, and the phenomenon of self-ignition of air conditioners has also attracted the attention of the public. Why is the air conditioner self-igniting, how to prevent self-ignition of the air conditioner, in addition to spontaneous combustion, what other issues need our attention? Let us explore together.
The line problem is the main cause of self-ignition of air conditioners.
Why does air conditioning ignite spontaneously? With this question, we visited relevant industry insiders. "The indoor unit and the outdoor unit of the air conditioner are likely to spontaneously ignite. The main reason is the fire caused by the electrical circuit." The person in charge of an air-conditioning brand in Hebei told reporters that "the line fire generally has the following conditions. First, The quality of the line itself, the use of wires from the informal manufacturer during the installation or transfer process. Because the connection wires of the air conditioner have performance requirements, for example, the line used in our air conditioner must be a neoprene cable. In this case, the capacity of the socket plug is too small, resulting in overheating. This situation is generally reflected in the cabinet air conditioner. Because the power of the cabinet air conditioner is usually large, the instantaneous current is high at startup, and it is very easy to burn the plug and spark. Safety problem. The third case is the problem of line aging. If the service life is too long, it will cause the line to age.
Wang Yong, the after-sales minister of Hebei Xingli Gree Electric Appliance Sales Co., Ltd. pointed out that if the air conditioner outside the machine accumulates too much dust, it will become an important fire hazard. Therefore, it is usually necessary to do the cleaning of the internal and external air conditioners. In addition, when the air conditioner is installed, it is too close to the combustibles such as curtains, and placed in the sunny place. Due to the long-term exposure of the sunlight, the running time is too long, causing the compressor to overheat and catch fire. In addition, starting immediately after the air conditioner is stopped is also a fire hazard.
How to prevent self-ignition of air conditioner
How to prevent the occurrence of spontaneous combustion of air conditioners? Industry insiders told reporters that the first thing to do is to avoid the installation and transfer of informal manufacturers, it is best to find a brand after-sales. For cabinets with relatively high power, it is recommended to install an air switch or a leakage protection switch, and connect the power cable of the air conditioner directly into the switch for normal use. When using it, please be careful not to switch the air conditioner frequently to avoid the heat accumulation caused by the instant start of the air conditioner.
Before the self-ignition, the air conditioner may produce the smell of plastic scorching or the situation of smoking. We must be vigilant about this taste and phenomenon. Once it appears, first cut off the power supply and find a professional to check and repair.
To prevent self-ignition of air conditioners, pay attention to the regular maintenance and cleaning of air conditioners. The surfaces of condensers, evaporators, filters, heat exchangers, and internal and external air conditioners must be cleaned. Some air conditioners never clean, and a large amount of dust accumulates in the air conditioner. The dust on the heat sink directly affects the heat dissipation function, resulting in self-ignition inside the air conditioner. In addition, the air conditioner has recommended service life. It should be regularly repaired after the service life. If the air conditioner is not used, the power should be cut off. Do not let the air conditioner stay in standby state, affect the service life of the air conditioner, and there are potential safety hazards.
Summary of recent air conditioning FAQs
In summer, air-conditioning is frequently used, and there are many problems. It is understood that the main problems of air-conditioning repair in Shijiazhuang City in the near future are concentrated in the two aspects of poor air-conditioning and refrigeration, and many people think that the air-conditioning refrigeration effect needs to be added to Freon. Certainly, as long as there is no leakage of fluorine, the air conditioner can not be freon for life, which causes the air conditioning refrigeration effect to be poor. In addition to the damage of the air conditioner itself, the machine cannot operate normally. It may be that the outdoor temperature is too high, the outdoor unit voltage is too low, and the outdoor unit is condensed. There is too much dust in the back of the device. If this is the case, you can do it yourself. If the outdoor unit does not dissipate heat well, this situation can cool the outside machine. The easiest way is to pour some water to the outside machine to cool down. If conditions permit, you can add a sunshade to the outside machine.
In addition, air conditioning leakage is also a common problem, to eliminate the problem of air conditioning itself, such as the installation of the sink is not in place, the installation of the indoor unit is not equal, most of the leakage is caused by the drainage of the drain pipe is blocked, the solution is to clear the drain pipe, usually pay attention to cleaning the air conditioner . If the indoor unit leaks, the internal water tray is clogged and needs to be disassembled by a professional. In the case of excessive humidity in the indoor environment, condensation may also occur on the downwind plate, which may cause dripping. In this case, the dehumidification function of the air conditioner may be turned on or the indoor environment may be dehumidified by other means.
Principle of correct use of air conditioner
First, health settings scientific use
If the set temperature is 2 °C higher, you can save about 20% of electricity. Do not pursue indoor temperature too high or too low during use. Although the human body is comfortable at the time, it is easy to appear in the case of sudden temperature changes. Discomfort and other conditions, while the temperature is set too high or too low will cause excessive power consumption.
Second, the most important time for maintenance
The filter screen is an important part of the air conditioner. If it is not cleaned for a long time, it will not only have an odor during use, but also affect the actual use of the air conditioner for cooling and heating efficiency, and increase the air conditioner power consumption.
Third, the closed room is very important
The indoor environment is also an important factor affecting the air conditioning power consumption. If the airtight effect is good, the air conditioner will quickly adjust the temperature after opening. If the airtightness is not good, the air conditioner will continue to be lost, and the air conditioner will always be in working state. rise.
Fourth, on-demand purchase
Air conditioners are selected according to their own area of ​​use. If you buy a small number of air conditioners to cool a large environment, the air conditioner will always be under load and will increase the power consumption of the product.
Fifth, avoid sun exposure
In summer, try to avoid daylighting, which can save 5% of power consumption.
Six, the angle should be appropriate
When the air conditioner is cooling, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect is better.
Seven, try to reduce the bending of the piping when the air conditioner is installed
It is necessary to keep the piping of the indoor and outdoor units of the air conditioner in a horizontal position, so that the cooling effect of the air conditioner is better, and the air conditioner is relatively more power-saving.
Eight, keep the air conditioning vents unobstructed
The air conditioning air outlet is smooth, which not only allows the air conditioner to quickly adjust the indoor temperature, but also reduces the power consumption caused by the air conditioner due to poor airflow.
