The world famous diversified corporation Hitachi was founded in 1910 in the Japanese town of Hitachi. The talented engineer of Namikhei Odair, who created the first electric motor in Japan, decided to open his own company and name it after his hometown. Translated from Japanese, Hitachi is "sunrise."

At first, Hitachi manufactured electric motors. After some time, Namikhei Odaira launched the production of voltmeters, galvanometers, transformers, fans. In the mid-twentieth century, Hitachi opened subsidiaries. And 1952 was marked by the release of the country's first window air conditioner. After 9 years, Hitachi air conditioning with a heat pump is produced, and after 6 years - an air conditioner that can drain the air without lowering the temperature. In the 70s, Hitachi became a leader in computer systems and microelectronics. In 1978, a computer-controlled air conditioner appeared with micro-sensors for temperature control. Today, Hitachi factories produce air conditioners not only in Japan, but also beyond its borders - in Malaysia (Hapm factory), in Spain (Hape factory). Hitachi's annual sales are approaching $ 80 billion. The company invests about $ 5 billion annually in research laboratories, and finances the work of scientists. Scientific innovations are used to create new air conditioners. One of the latest developments by Hitachi engineers is an inverter-type air conditioning system, as well as split air conditioners and multi-split systems. Another successful Hitachi development is the SetFree refrigerant variable air conditioning system.
