We are streamlining the trial production and evaluation of high-quality, high-performance, and highly comfortable products utilizing data and simulations that visualize airflow, noise, vibration, etc. from air conditioners. In addition to the conventional technology development such as room temperature and airflow control, we continue to work on the development and new technology to realize further comfort, proceeding with various verifications on the relationship between the sensible temperature and the feeling of warmth and coldness of each part using thermal mannequins and subjects.
