The scorching summer weather makes using air conditioners essential to feel comfortable, relaxed, healthier, and have better sleep at night. However, many people are concerned about their electricity bills when using air conditioners.
Is setting the air conditioner to 28 degrees Celsius energy-efficient?
The answer to whether setting the air conditioner to 28 degrees Celsius is energy-efficient or not depends on the temperature difference between the room and the outside environment.
Typically, air conditioners are most efficient when the condenser temperature is below 48 degrees Celsius and the room temperature is set to 19 degrees Celsius or higher. According to experts, to save electricity, you should set the air conditioner temperature to be 6 to 10 degrees Celsius lower than the outside temperature.
Is setting the air conditioner to 28 degrees Celsius energy-efficient?
For example, when the outside temperature is 40 degrees Celsius, setting the air conditioner to 30 degrees Celsius can save electricity while still providing sufficient cooling. If you set the temperature below 25 degrees Celsius, the air conditioner will have to run at full capacity and will definitely consume a significant amount of electricity.
However, if the outside temperature is around 30 – 35 degrees Celsius, it is advisable to set the air conditioner temperature to 26 – 28 degrees Celsius to save electricity. If you set it to 30 degrees Celsius, the air conditioner compressor will turn on and off frequently, resulting in a considerable amount of energy consumption.
Therefore, to determine whether setting the air conditioner to 28 degrees Celsius is energy-efficient or not, you need to consider the outside temperature and adjust the temperature to the most appropriate level. Experts recommend not setting it below 20 degrees Celsius. A temperature range of 25 – 28 degrees Celsius is most suitable for health.
Should you use a fan while using the air conditioner?
Using a fan in a room with air conditioning is a preferred option during hot weather due to the following benefits:
Facilitating air circulation
The air conditioner draws in air from the room and passes it through the cold filter system to cool and remove dust. However, it takes time for this cool airflow to circulate evenly throughout the room. You need to set the air conditioner to a low temperature, around 23 – 24 degrees Celsius, and wait a while for the whole room to cool down through air circulation. This means that more electricity will be consumed, and the air conditioner will have to work more actively.
Some other side effects include dry skin, body temperature imbalance, possible headaches, dizziness, sore throat, or heat shock if you frequently have to leave the room.
However, when using a fan (ceiling fan or misting fan), the airflow from the fan helps to accelerate and evenly distribute the air circulation, improving the above-mentioned issues.
Energy-saving
When using the air conditioner in combination with a fan, you only need to set the temperature to 27 – 28 degrees Celsius to achieve a cool and comfortable feeling. Without using a fan, the aforementioned temperature range will not be sufficient to provide a comfortable cooling effect. You will have to lower the temperature further, which will result in much higher electricity consumption compared to using a fan.
Is it beneficial to use an additional fan while using the air conditioner?
Health benefits
If the air conditioner is set to a very low temperature, the humidity will decrease, causing dry skin, stuffy nose, throat inflammation, etc. When using a fan in addition to the air conditioner, you can set the air conditioner to a moderate temperature, which helps to mitigate potential health issues.
However, you need to remember to clean the fan regularly. You may not notice the accumulated dust when the fan is operating, but when you turn it off, you will be surprised by the dirt clinging to the fan blades.
Increasing the durability of the air conditioner
When using a fan, you don’t need to set the air conditioner to a very low temperature because the fan assists in circulating cool air around the room.
This reduces the load and operating time of the internal components of the air conditioner. As a result, the device will have prolonged lifespan as it operates at a moderate level, without excessive strain.
With the answers to whether setting the air conditioner to 28 degrees Celsius is energy-efficient and whether to use an additional fan while using the air conditioner, you will now know how to use this device more effectively.
