Unexpected air conditioner: Dangerous and deadly

Many families have a habit: the hotter the weather is to regulate at low levels, even for air conditioning running 24/24. They did not know that this habit could lead to the risk of harming due to overload.

In the summer, air-conditioning seems to become an impersonal object in most families. To cope with the scorching heat, many families have a habit of turning on the air conditioner 24 hours, running from day to day without turning off to regulate the rest time. Not only that, families also regularly regulate at very low temperatures.

According to Mr. Hoang Van Bach - who has many years of experience in repairing and installing air conditioners in Khuat Duy Tien (Thanh Xuan, Hanoi), air conditioning is like electric ball, electric fan, electric cooker, . All have a certain lifespan, but the shorter the life, the shorter the life of the device, even when an explosion is in use.

Should not be conditioned at too low temperature for a long time.

Specifically with air conditioning. With the days when the weather is not too hot, the user should set the air conditioner at 25-28 degrees Celsius. This heat level ensures comfort in everyone, while saving electricity.

However, with the days of hot weather up 38-40 degrees C, many families have a habit of using continuous air conditioning, open 24 hours, even running for several days and always keep the temperature below 20 degrees C , causing the air conditioner to brace and run. In this case, the electricity cost is not only more expensive but the heater of the conditioner also has the risk of exploding, endangering the user.

Mr. Bach explained, the air conditioner will operate at full capacity to reach the temperature that users install. The relay of the air conditioner will automatically disconnect the hot zone when it reaches this temperature. The process will be repeated because the room temperature after the heat exchange process with the external environment will increase, the air conditioner will have to restart to cool and maintain at the pre-set temperature. The higher the outdoor temperature, the more the hot air conditioner has to work.

Notably, with the hot sun below 40 degrees Celsius, installing the air conditioner too low means that the "corn pressed" hot air conditioner works continuously, without time to stop. While the air conditioner unit is equipped with a circuit board containing electronic components, when operating, it will generate a certain amount of heat. So, when operating continuously for a long time, the hot zone will raise the temperature very high. At this time, it is very explosive.

The heater regulates an explosion hazard if improper use of air conditioner is used.

In addition to the risk of fire and explosion, constant air conditioning at too low temperatures (below 22 degrees Celsius) also has a negative impact on health. For example, users will suffer from dry skin, affected respiratory system (sore throat) and may experience heat shock when stepping from a cold room to step out and vice versa.

According to Bach, the most safe and durable use of air conditioner is not to allow the air conditioner to run 24/24, set the temperature at 25-28 degrees Celsius. Because, at this temperature, it will ensure health for users, help save electricity and the life of the air conditioner will be extended.

However, when the weather is hot and hot, such as the historical heat wave in Hanoi, if the air conditioner is 25-28 degrees C, you still don't see a cool room, the user should add an electric fan or a fan water in the room. At that time, there will be wind, pushing cold air to spread throughout the room. Air conditioning thus does not have to run in overload.

In addition, Mr. Bach also noted that when choosing to buy air conditioner, pay attention to appropriate capacity. Because, if the air conditioner capacity is small with the room area, the air conditioner will have to run continuously to cool the room, and the electricity will be more expensive. Not to mention, overloading also caused the air conditioner to fail. This issue, when buying air conditioner, staff will advise very well.
