Daikin, Japan.

Daikin is a Japanese manufacturer of air conditioners, founded by Akira Yamada in 1924. Its production facilities are located not only in Japan, but also in other countries (Belgium, Thailand).

The company manufactures both industrial and domestic air conditioners. Other components for air conditioners are also manufactured, including fan coil units, hydronic modules, compressor-condenser units, and other components. VRF systems and water-cooling units are also manufactured. The company produces approximately 2.5 million units of equipment annually.
The company's achievement is the development of a packaged air conditioner with a heat pump. Continuous research has led to the creation of various advanced systems: Hi-VRV, D-BACS, HRV, DAIKIN AC, and DAIKIN VRV.
This narrow focus facilitates detailed product research and improvement. Daikin is a major manufacturer of air conditioners, refrigeration units, and ventilation systems. During research, every air conditioner component undergoes laboratory testing with strict adherence to all quality standards and regulations.
