Warawan Chitaroon, its general director, said Thailand exported about US$850 million worth of air conditioners in March alone, up 16.7% from the same month last year.
In the first quarter of this year, $2.27 billion worth of air conditioners were exported from Thailand, a rise of 2.85% over the same quarter last year, she added.
The Manufacturing Production Index for air conditioners in Thailand reached 144.39 in March, up by 7.1% year on year and is forecast to remain high.
Thailand's temperatures are rising due to global warming, and in April – the hottest month – the heat index, which combines temperature and humidly, is equivalent to 50 degrees Celsius, Warawan said.
The air-purifying function in air conditioners has also driven up domestic demand, especially in Bangkok and Chiang Mai, where air pollution is acute, she said.
Thailand has become the world's second-largest exporter of air conditioners after China, she said.
About 80% of air conditioners exported from Thailand go to the United States, other Asean nations, and the Middle East, Warawan said.
She said 75% of air conditioners made in Thailand are exported and the rest are sold domestically.
