How can air conditioners be used to save electricity?

For many people, using the air conditioner properly is not easy, and using it to save electricity is even more difficult. But if you follow these steps, you will no longer have to worry about your monthly electricity bill.

Choose to buy a line of air conditioners that suit your needs

To save electricity effectively, users should choose an air conditioner with a capacity suitable for the room area.

For closed rooms not exposed to direct sunlight. Let's apply the formula:

• 1m2 x 600 BTU to get the right power (BTU is a British thermal unit).

E.g.:

• If you need to buy an air conditioner for a room with an area of 20m2, you will have the formula 20m2 x 600 BTU = 12,000 BTU, which is equivalent to an air conditioner with a capacity of 1.5 horses. (1 Hp is equivalent to 9,000 BTU).

For rooms with direct sunlight. It would help if you chose a machine with a more substantial capacity, equivalent to the formula:

• 1m2 x 800 BTU = 16,000 BTU, equivalent to an air conditioner with a capacity of 2 Hp.

In addition to buying air conditioners that use PAM inverter technology, if you use the machine regularly for a long time, you should also choose products with advanced power-saving technology, such as sensor magic eyes. "I-see" on the Mitsubishi Electric air conditioners.

The "I-see" sensor magic eye mode will:

• It emits infrared rays to scan the room at an angle of 150 degrees to measure the temperature in each space area (within 6m).
• Determine the position of the person sitting in the room to adjust the airflow operation.
• Recognizing that the room is not occupied, the machine will automatically reduce its productivity by 10% after 10 minutes and 20% after 60 minutes.

Install an air conditioner

One of the factors affecting the operation of the air conditioner or not is the installation process. When you are about to install the machine, you need to pay attention to the following:

- Install the outdoor and indoor units so that direct sunlight is limited.

- Install the indoor unit vertically in the room. The indoor unit must be hung high enough (over 2.5 m) so that the cold wind can spread evenly in the room.

- The outdoor unit is hung in a well-ventilated place, not directly facing the sun's direction. The location must be easy to access, repair, and clean the machine. The gas pipe connecting the indoor and outdoor units must be covered with good insulation and buried in the sound wall, and is pre-assembled before painting and hanging on the wall.

- The distance between the outdoor unit and the indoor unit is as close as possible, and the height difference is not more than 5m to avoid reducing the cooling capacity of the machine.

- Communal water pipe from the indoor unit should use a rigid plastic pipe buried in the wall and have a lower slope than the indoor unit to drain water quickly and avoid fogging on the tube to stain the fence.

- The power cord goes negative from the protection switch to the standby at the indoor unit installation location to facilitate powering the machine.

Use process

During the process of using the air conditioner, you should also pay attention to a few things:

• Arrange furniture not to obstruct the airflow; this helps the room cool faster, using less electricity.
• Incandescent lamps or sunlight are the causes of the heat, causing the air conditioner to work harder. So, when not in use, turn off the lights.
• Usually, air conditioners have a temperature range of 16–30 degrees Celsius so that you can adjust the temperature to about 24–26 degrees Celsius in the morning. You can change the difference by 5 degrees at night compared to the outside temperature. As a result, the weather will be better for health and save more electricity.
• If you have not used the air conditioner for a long time, please disconnect the power breakers from the machine. Because if you keep the device in a standby state and restart it with the remote, it will also consume a significant amount of energy.
• Please press the "ECONO" button on the remote control. It is the button to adjust the power saving mode.

Econo Cool is one of the intelligent power-saving features equipped on Mitsubishi Electric air conditioners that will automatically adjust the wind direction based on the temperature at the vent.

Therefore, the set temperature can be 2 degrees Celsius higher than the normal mode (without using this feature) without sacrificing comfort and increasing energy efficiency by 20%.

Maintenance and cleaning up

One of the ways to help the machine work better and save electricity optimally is to maintain and clean it periodically every 3–4 months, which will help reduce the machine's operating capacity, saving up to 45% of electricity.

In addition, you should check the outdoor unit to see if the fins are dusty. If so, call a staff member to service and prevent the gas. Because the outdoor unit is dusty and insufficient gas will lead to reduced cooling efficiency and longer cooling time for the room, resulting in more electricity consumption.

Hopefully, the above simple ways will help you save maximum power consumption during this hot summer when you need to use the air conditioner.
