The Uncomfortable Truth About Air Conditioning Fans
In the scorching heat, many people rush to buy air conditioners because they are quite cheap, do not require installation, are easy to move and save electricity. However, in addition to the above advantages, the truth is that air conditioners also have many disadvantages that users need to know to consider before buying.
With prices ranging from only 1.7-6 million VND for an air conditioner fan depending on the brand, many people rush to buy air conditioner fans to cope with the scorching hot weather in the summer. However, many people also wonder if this air conditioner fan can really help their house cool like an air conditioner?
According to electrical experts, air conditioners are air cooling devices. They operate on the principle of water evaporation. Accordingly, inside the fan there is a cooling plate, a pump and a fan system with a specially designed large motor, which helps to suck hot air from the outside environment.
The pump has the function of pumping water to wet the cooling pad so that when the air passes through this cooling pad, it will absorb heat, lowering the temperature of the air quickly. Then the cold air is blown out to reduce the temperature of the surrounding environment.

| Consumers need to know the advantages and disadvantages of air conditioners to consider before buying. |
Advantage:
With the above operating principle, air conditioners have many advantages. For example, in terms of cost, air conditioners are cheaper than air conditioners but higher than regular electric fans.
Specifically, in the current market, to buy an air conditioner fan, consumers often have to spend from 1.7-6 million VND/fan depending on the brand and capacity.
Regarding power consumption, depending on the capacity, air conditioner fans have different power consumption levels. However, due to its simple structure, air conditioner fans consume a negligible amount of power. If compared with air conditioners, air conditioner fans consume only 1/7 to 1/10 of power.
In addition, the mechanism of air conditioners is to use steam to cool, so they have a moisturizing effect, do not cause dry skin and discomfort like when using air conditioners.
Another advantage is that buying an air conditioner fan does not require millions of dong in installation costs like an air conditioner, just plug it into the power source and the air conditioner fan can operate. In particular, with the ability to move easily, users can change the position of the fan as they like, actively directing the wind to every corner of the room instead of passively like when using an air conditioner. The fan can also be brought to the living room or into the bedroom whenever needed. When using it, users do not need to close the windows and main doors like when using an air conditioner.
Disadvantages:
Besides the advantages such as low price, convenient to move, energy saving... the truth is that air conditioner fans also have many disadvantages that users need to consider before buying.
Specifically, when going to the supermarket to buy an air conditioner, customers will feel the cool air blowing out from the air conditioner along with the advertisement that the temperature will decrease by about 15 degrees Celsius. However, this is only an index under ideal conditions and usually cannot be maintained for a long time.
With the climate conditions in Vietnam, according to electrical experts, the air conditioner fan only helps reduce the temperature by 5-7 degrees Celsius. This type of fan also only works best in sunny and dry conditions. If the humidity is too high, the fan will only function as a normal electric fan plus add humidity to the room.
Furthermore, the cooling efficiency of the air conditioner also depends on the room space. The larger the room, the lower the cooling capacity of the air conditioner fan. Not to mention, the air conditioner fan cannot adjust the temperature like the air conditioner. The increase or decrease of the fan speed is only relative.
In addition, air conditioners consume a lot of water and must be constantly refilled. Because, to cool the room, air conditioners need a large amount of water to operate. According to the manufacturer's specifications, 20 liter tanks can be used continuously for 4-8 hours. In case there is no more water in the tray, the air conditioner will become a regular electric fan.
Along with the existence of the water tray, users also need to check and clean it regularly to avoid this part becoming a place of mold, odor accumulation or a place for mosquitoes to breed.
Another drawback that annoys users is the noise of the air conditioner fan. Notably, the higher the capacity of the air conditioner fan, the louder the noise.
In fact, Mr. Duong Anh, a person who has used an air conditioner fan, shared that the air conditioner fan will create extremely high humidity in the room because every day 20-50 liters of water must be poured into the fan depending on the fan. If the room is closed, it will make the room even more stuffy, along with high humidity, which is an ideal environment for bacteria to grow, easily causing respiratory diseases for young children. Especially after stopping the fan, the cooling pad that the water flows through is in a wet state, so bacteria will grow, so the next morning when the fan is turned on, it will smell very bad, even rotten./.
