Refrigeration expert shows how to use air conditioner 'super economically'

Refrigeration experts say that using the air conditioner in Dry mode saves more electricity than using it in Cool mode, however the cooling ability of Dry mode is not very effective if the outdoor temperature is too high.

A few days ago, many social media users shared an article about a simple tip to help air conditioners save electricity from an Australian woman named Sue Evison.

According to Ms. Sue Evison: When using the air conditioner, just use the remote control to switch the mode from "Cool" to "Dry" to make the air in the room cool without wasting electricity.

Ms. Sue Evison said that she herself has applied this method for a while and found it really effective. The room with the air conditioner on Dry mode in her house is always cool and the power consumption is reduced by up to 10 times.

After reading the article, many people believed and shared the article for their friends to apply. Therefore, PV had a discussion with experts in electronics and refrigeration about this issue.

Accordingly, sharing on VnExpress newspaper,Dr. Tran Van Thinh, Department of Electrical and Electronic Equipment, Hanoi University of Science and TechnologyIt is believed that when operating in Cool mode, the air conditioner takes heat from inside the room to push it out to the outside hot block, helping to reduce the temperature and cool the air in the room, so it consumes quite a lot of electricity.

In Dry mode, the air conditioner will suck moisture out of the room, returning fresh and drier air, so it consumes less electricity than cooling mode.

Therefore, in case the outdoor temperature is not too hot (about below 36 degrees Celsius) and the humidity is high, using Dry mode will be very effective in creating a comfortable feeling in the room, and saving electricity.

However, on hot days with low humidity, using Dry mode is meaningless because it does not have the function of reducing the temperature, making the air in the room still hot and uncomfortable, and at that time, the only option to cool is to switch to Cool mode.

Sharing the same opinion, an electrical refrigeration expert also said that using the modes flexibly on the air conditioner remote control also helps users save a lot of electricity.

For example: When sleeping, users can leave the air conditioner in Sleep mode. In this mode, the machine will automatically increase the room temperature by 1oC - 3oC in the morning, helping the body feel more comfortable while sleeping and also saving more electricity.

Or in the case of outdoor temperature is not too hot and humid, using the air conditioner in Dry mode is also effective and economical. Because in Dry mode, the air conditioner runs in dehumidifying mode. This mode helps reduce the humidity in the room, increasing the evaporation of sweat on the skin, helping the body release energy, reduce body temperature and ... feel cool but only consume a part of the electricity.

In addition, this refrigeration expert also shared that in order to use air conditioners effectively, economically, and durably, users need to pay attention to the following issues:

1. Choose the right air conditioner for the room: The most important factor in choosing an air conditioner is the room volume. In addition, it is necessary to calculate factors such as: wall and roof materials; Room insulation; Number of people regularly present in the same room; Room ventilation; Solar radiation affecting the room, etc.

2. Choosing an energy-saving Inverter air conditioner is also an important factor to save a large amount of electricity bills.

3. Regularly clean and maintain the machine to ensure good performance of the machine. Simply cleaning the dust accumulated in the filter can reduce the machine's operating capacity by up to 15%, helping to save a large amount of electricity.

4. Arrange the room to be closed, do not leave the room open. If the room is open, the cold air will escape, the outside temperature will affect the room temperature, so the air conditioner will have to work harder and consume a lot of electricity.

5. In addition, when using air conditioning, the room temperature should not be set too low compared to the outside temperature. Setting the room temperature too low will waste electricity and is not good for the health of the person using the air conditioning.

6. Do not let sunlight shine into the room.

Sunlight can increase the room temperature, so the air conditioner will have to work harder. Therefore, for rooms with glass doors, there should be curtains to block out direct sunlight.

7. Arranging furniture properly so as not to block ventilation also helps users save electricity.

9 Can use fan with air conditioner:

Using a fan will help circulate cool air in the room, which also means you don't have to turn the temperature down too low, thus using less electricity.
