What you need to know About your air conditioners SEER.

The SEER (Seasonal Energy Efficiency Ratio) value is used to measure energy saving efficiency under seasonal changes in outside temperature. By taking the values of climate change that affect the operation of air conditioners into consideration together. SEER values are usually only used with inverter air conditioners. Because this type of air conditioner has a sensor system to detect the room temperature that is affected by outside weather conditions such as heat from sunlight. Coolness from cold wind or rain It is therefore appropriate to use the SEER value as a measure of energy efficiency, and the higher the energy efficiency value, the better. Because it will help you save more electricity. You can see the SEER value on the Energy Saving Fiber 5 label that indicates the efficiency value. Or you may notice it on the label that indicates the type of your air conditioner as shown in the picture.


1. Energy Level : You can notice from the arrow pointing to the number 5 that some brands may have additional arrows that move to stars 1, 2, and 3. But that doesn't mean the efficiency is lower, but it will indicate more energy-saving efficiency. At a high level, with star level 3 being the most energy efficient value.

2. Product Type It is information that specifies the type of those electrical products. For example, if it is an air conditioner It will be specified as an inverter air conditioner or a fixed speed  air conditioner.

3. Electricity Charge : It is a unit showing the cost of electricity used. To help you compare with the same type of electrical appliances before deciding to buy, such as a 12,000 BTU air conditioner, brand A, electricity cost 8,560 baht/year and a 12,000 BTU air conditioner, brand B, electricity cost 9,670 baht/year. It can be seen that brand A air conditioners will It has a cheaper average electricity bill, so you may have to decide to buy brand A to help save on electricity costs.

5. Product Detail The brand name will be specified. Product model and product size

6. Label No.5 Website This website provides information on various products certified with the Energy Saving Label 5.

Difference between SEER and EER

As you know above, the SEER value is indicates the energy saving efficiency under the outside temperature. Which will be used with inverter air conditioners. But there is another value called the EER value, or an abbreviation for Energy Efficiency Ratio, which is a measure of the energy saving efficiency of general air conditioners with fixed speed systems because of this type of air conditioner, the air compressor will frequently cut off to make your air conditioner maintain the temperature in the room This may result in wasting more electricity than an inverter air conditioner. By observing the EER value, check the same area as the SEER value that is the word efficiency value. To compare for you to observe more easily You can see the You can see the picture below:


But when choosing an air conditioner that helps save energy, other factors should be considered as well, such as choosing a brand that has a fiber saving mark. 5 Selecting the size of the air conditioner that is appropriate for the size of the room, with small rooms ranging from 12-30 square meters, may be suitable. Air conditioner 9000-18000 BTU, but if the room is larger than 30 square meters or more, you should choose an air conditioner 21,000-30,000 BTU, including selecting the type of air conditioner that is appropriate for the space because there are many types of air conditioners, whether Wall mounted, ceiling mounted, floor standing, etc.
