Lately, I’ve only heard people complain about the weather being hot, hot, and getting hotter every day. Especially when it’s hot and you hope to rely on the coolness from the air conditioner, but it appears that it doesn’t help much. Because it dissipates less heat. It also causes the electricity bill to skyrocket each month. But have you ever known that the reason why the air conditioner may not help with cooling may be a mistake in using the air conditioner caused by the user? And these are those mistakes that should be avoided.
1. Select an air conditioner BTU that is not suitable for the size of the room that will be used.
Before choosing an air conditioner, you should consider the size of the room in which the air conditioner is intended to be installed. For calculating the number of BTUs appropriate to the space, there is a BTU calculation formula:
BTU = Room area (width x length) x difference
Differences can be divided into 2 types.
600 – 700 = Room with little heat used only at night.
700 – 800 = Room with high heat used during the daytime.
For anyone who uses the room often or a room with high ceilings If sunlight can reach you, you may need to increase the BTU by about 10 percent, but it is not recommended to buy an air conditioner with too many BTUs because even though it can cause a lot of cooling, But it does not help reduce the humidity in the ยูฟ่าเบท room. And that humidity causes the room temperature to increase from before. Plus it’s a waste of money for no reason.
2. Open the windows and doors while turning on the air conditioner.
The function of an air conditioner is to draw hot air from the room through a refrigerant that absorbs heat from the air. When the air cools, it is blown back into the room. The hot air will be expelled from the back. That’s why windows and doors should be closed. To prevent hot air from coming back in instead. and will cause the performance of the air conditioner to decrease.
3. Set the temperature too low.
After being tired and exposed to the heat outside, when you arrive home, you want to feel cool and comfortable as soon as you enter the house. But when you enter the house, the house is hotter than you thought. You may have accidentally turned on the air conditioner and set the temperature as low as ten degrees Celsius to cool your room instantly. But that is not recommended method. Because setting the temperature lower than the desired cooling level does not help the air conditioner work faster.
Because if you intend the room temperature to be 25 degrees Celsius, but you set the temperature to 18 degrees Celsius, the air conditioner will continue to work until the room reaches the set temperature. This means that the room will be too cold. and cause unnecessary energy wastage. Therefore, it is recommended that you set the desired temperature and let the air conditioner work as it should.
4. Do not turn on the fan to circulate air.
Many people tend to turn on their fans when the weather is hot. and change to using air conditioning when the weather is hotter than before or starting to feel uncomfortable But no one may know that air conditioners work better than before if they are used together with fans. Especially the ceiling fan Because the fan helps make the air circulate better. While you may be drenched in sweat The fan will dry your sweat faster. This has a cooling effect on your skin.
5. Neglecting to change the air filter.
No matter how clean your room is But there are small particles. Floats in the air and is sucked into the air conditioner during use. A clean air filter is an important thing that affects the performance of the air conditioner. And the accumulation of particles will reduce air flow, causing the air conditioner to work harder. And if the filter is dirty, energy consumption will increase by up to 15 percent, so the air filter should be replaced. If the air conditioner works every day Change the air filter once a month, or if you use it frequently, change it every 3 months. But if your air conditioner has a filter that can be removed and cleaned. Then take it out and clean it regularly. or buy a replacement filter
6. Forgetting to clean your air conditioner between seasons.
During the summer, you may use your air conditioner more often than during other seasons. But don’t forget to clean your air conditioner during the season. Because even though the air conditioner is not used Inside the air conditioner is an easy place for bacteria to accumulate. which is the cause of asthma and respiratory disease
7. Lack of good maintenance
Regular maintenance of your air conditioner not only extends its lifespan. But it also makes the air conditioner work more efficiently, meaning faster heat dissipation. and save energy At least you should check the operating condition of the air conditioner about once a year or if there are strange things. If something happens, such as noise during use, dripping water, or an odor, you should call an expert to check the condition of the air conditioner. The more you fix it from the beginning It will save more money than leaving the air conditioner unusable. and must be replaced
8. Ignore the source of heat.
If possible, reduce heat sources within your residence. This will help increase work efficiency. For example, if there is only one window Should add channels for air circulation, sealing cracks and leaks around the building. Cover sunny windows with thick, light-colored curtains. Close during the hottest part of the day. If possible, add insulation to the walls. Avoid high CPU usage on your computer or laptop. Avoid using heating devices such as washing machines. or the dryer while the air conditioner is on Limit cooking time in the oven. But if you want to reheat the food, choose to use a microwave instead.
