MEA confirms: Your air conditioners consume more power in hot weather!

MEA confirms: Your air conditioners consume more power in hot weather!

The Metropolitan Electricity Authority (MEA), led by Mr. Jumpote Himacharoen, Corporate Communications Director, revealed the result of an MEA-led experiment that found that energy consumption in hotter temperatures can be 14 percent higher than at other times.

“During summer, the high rate of electricity consumption is due to intensive power usage by air conditioners in the higher temperatures,” Mr. Jumpote explained. 

The experiment installed a 12,000-BTU air conditioner, set at 26 degrees Celsius, then measured and compared the electricity consumption when the outside temperatures were set at 35 and 41 degrees Celsius.

“The result revealed that the air conditioner consumed on average 0.69 unit and 0.79 unit per hour when the outside temperatures were set at 35 degrees Celsius and 41 degrees Celsius respectively. So when the outside temperature rose by 6 degrees Celsius, the air conditioner’s electricity consumption increased by 14 percent.”

The experiment found that if a unit of electricity costs 3.9 baht, the air conditioner will cost 2.69 and 3.08 baht per hour to run at 35 and 41 degrees Celsius outside temperatures. When used 8 hours per day for 30 days, it will cost 646 and 739 baht accordingly, or an additional 93 baht per air conditioner.

However, electricity in Thailand is charged at progressive rates. The higher the consumption, the higher the rate. Therefore, the hypothetical calculation might be lower than reality. 

As a specialist in power distribution, MEA therefore recommends setting the air conditioner at 26 degrees Celsius, cleaning the air conditioner at least twice a year, keeping the units well-maintained, and turning on fans to help cool instead of lowering the temperature of the air conditioner. These tips will help save energy, reduce electricity costs, and help reduce greenhouse gas (carbon dioxide) emissions and PM2.5 pollution.
