Hitachi Air Conditioning held a press conference at the Sheraton Taipei Hotel to launch its 2025 air conditioning series products. At the conference, it announced the launch of the latest “Freeze Clean 3.0+” technology, which will further improve the cleaning and energy-saving performance of air conditioning equipment. This technology upgrade covers the simultaneous freeze cleaning of indoor and outdoor units, and introduces a patented fan automatic cleaning function in designated air conditioning models to improve the operating efficiency and service life of air conditioning products.
At the press conference, General Manager Tsai Ching-hai of Hitachi Johnson Controls Taiwan Air Conditioning Equipment Sales Co., Ltd. and President Shinichi Iizuka of Hitachi Johnson Controls Taiwan Co., Ltd. attended the annual event and shared Hitachi air conditioners’ technological innovations, product advantages and future vision in 2025. At the same time, Hitachi also invited the annual product spokesperson Zhang Junning to promote the new products.
Zhang Junning, the spokesperson for Hitachi Air Conditioning 2025, was also invited to attend the press conference. She not only shared her experience of using Hitachi air conditioners, but also praised Hitachi AI Super Inverter Dehumidifier. Its high-efficiency dehumidification ability helps her leather clothing and bags stored at home to avoid mold due to humidity when she works away from home for a long time.
Since the official release of the freezing technology, Hitachi Air Conditioning has continued to update this technology almost every year. According to Hitachi Air Conditioning, as the use time of air conditioners increases, indoor and outdoor units are prone to accumulate oil and microorganisms, affecting operating efficiency and air quality. This year, the company has upgraded the “Freeze Wash 2.0” technology from last year. In addition to effectively softening and removing internal dirt through high-temperature heating and freeze washing procedures, the new “Freeze Wash 3.0+” technology has been tested and found to increase fan air volume by about 16% and reduce energy consumption by about 7%.
In addition, the newly added exclusive patented automatic fan cleaning function can regularly remove dust and dirt to ensure air quality and equipment operating performance. As for the air conditioning products equipped with “Freeze Wash 3.0+” technology launched in Taiwan, they can all automatically start the cleaning process according to personal usage habits.
In addition, Hitachi Air Conditioning also launched the “Freeze Wash 3.0” technology, which also has the function of synchronized freeze washing for indoor and outdoor units, and is equipped with the top series models launched this year.
