How to avoid unnecessary power consumption of air conditioners

In the hot summer, the use of air conditioners is essential in families. This also means that monthly electricity bill will increase significantly. So open the air conditioning and choose the temperature how to freeze quickly and save electricity? Try these power saving tips when using the air conditioner below

Step into the bedroom, open the air conditioner and select the heat level of 16 with the desire for the room will be the fastest cooling. With that action, you're wasting your electricity bill! This article will help you waste money on such things.

How does air conditioner use electricity?

An air-conditioner has four main engines: the compressor motor (consumes the most power, about 95% of the total capacity of the air conditioning); cooling fan ; convection in the room and reversing motors located in the cooling tower. The most common types of air conditioners now have the automatic shut off function of the outdoor platform when the room has reached the required cold. Convection fans in the refrigeration units are active during the time the machine operates at fast or slow speed depending on the user. Reverse winding motors operate or stop at their option.

In terms of operation, there are two types: conventional and frequency converter.

With conventional air conditioners, the power consumption is relatively high and life expectancy decreases due to repeated reboots during continuous use. At the same time, the room temperature will fluctuate sharply (± 2 ° C).


For example, the machine is open at 24 ° C. At this point all the engines of the machine are operating until the room reaches a temperature of about 22 ° C - 24 ° C, the relay will automatically shut down the operation of the heating platform. After a certain period of time, depending on the heat exchange of the room with the surrounding environment, the room temperature will increase to 24 ° - 26 ° C, the heating platform will be restarted and lower the room temperature. about the desired level. The temperature difference of ± 2 ° C for 22 ° C and 26 ° C is due to the inertia of the machine. For example, when a room temperature sensor reaches 24 ° C, it will issue a shutdown command. Previously cooled air was blown into the room to reduce the room temperature. Similarly, when the room temperature rises above 24 ° C, the engine returns to normal operation, but it takes a while for the engine to cool down, at which time the room temperature rises.

Air conditioners should be cleaned periodically, on average every 6 months. With a net filter should clean more often to prevent dust clinging

The inverter uses a modern control technology, which causes the compressor to operate at an increased capacity until the room temperature reaches the required level. Operate at a moderate level to compensate for the heat generated in the room (electrical appliances, heat from the people ...) and heat from the outside to pass through walls, doors ... The power will increase or decrease depending on the difference between room temperature and set temperature for air conditioning. Thanks to this method of control, inverter air conditioners can save power by 30 - 50% compared to conventional machines. However, to achieve the above savings, the machine must be used under certain conditions as shown below.


It should also be noted that due to the fact that it is equipped with newer technologies than conventional machines, the frequency inverter is usually 30-50% higher than other machines.

Optimum temperature when used

Air conditioner works only when the temperature of the heat exchanger is below 48 ° C and room temperature is greater than 19 ° C, breaking these limits will result in inefficient operation of the heat exchanger. very low.

When starting the machine, you should only select the desired cooling temperature, then choose the additional rapid cooling function shown on the remote control that actually increases the convection fan speed in the cooler . Avoid placing the temperature to the lowest level of the machine because this does not help achieve the desired temperature faster, but only consumes more power as the machine must operate until it reaches the lowest temperature it can stop. again.


To use electric air conditioning is effective, we should choose the right temperature. The temperature of the environment in which the human body is adapted is between 25 and 27 ° C. Therefore, choosing a temperature of 26 ° C is to ensure comfort in living and save energy. Machines reach temperatures as remote or not due to the temperature sensor mounted on the cooler in the room, which usually does not affect over time. So in the case of old machines, still choose 24 ° C room will still reach that temperature, but will consume more power.

Installation in a reasonable position

Choosing the right place to install the air conditioning system will help save energy. The air conditioner should be installed in a well ventilated place, preventing the sun from shining inside the rig to increase the temperature of the equipment. In areas with high winds, the direction of installation is good for cooling fans blowing perpendicular to the wind direction. This will increase the heat output of the device. Caution, do not install the heating rig where there is a source of heat, exhaust fumes or chemicals that are contaminated or corroded.

The difference between the height and the distance between the cooler and the rigid frame needs to be arranged reasonably and shortestly to save both the cost of materials and the consumption of electricity. For conventional air conditioning, the length of the gas pipeline should not exceed 5m and the height difference should not exceed 3m. Exceeding these norms will significantly reduce the cooling capacity of the system.

Saving electricity during air conditioning use

In the chillers are two sets of wings help adjust the cold wind out of the truss in the desired direction. The user should adjust the airflow so that the cool air blows to the coolest place.

Always turn off the air conditioner when there is no need to use it. If there is no need to use it for a long time, the user should turn off the power source (aptomat) because if only by remote control, the machine will still be consumed underground and for safety reasons. Air conditioners should be cleaned periodically, on average every 6 months. For air filters, cleaning should be done more frequently, preventing dust deposits.

Reassemble furniture so that it does not block the ventilation passage

Turn off unnecessary light bulbs for quicker cooling, do not turn off the power or adjust the machine too much to restart the machine will consume a lot of energy, so keep the temperature stable.
If combined with the fan and to keep a cool water tank will help improve efficiency because fans help to cool the air in the room.
If you do not leave home for too long, do not turn off the air conditioner. It is best to increase the temperature of air conditioning to the highest temperature (30 or 32 degrees) and close all windows, curtains blinds again. Covering the room will prevent the sunlight from entering the room to rise too high. When you return, you may find it hot in a few minutes, but the heat is not so great that your air conditioner has to cool down from the start.

Although air conditioners have wind chillers that help bring the cool air to the right direction, you need to pack your belongings so that they do not obstruct the wind direction so you will feel cool faster, less electricity, more powerful.
