This air conditioning system, which won the Chairman's Award at the 2020 Energy Conservation Awards, is not a typical convective air conditioning system. Instead, it circulates warm and cool air throughout the entire floor, maintaining a uniform temperature in the room. By using radiant panels, it converts the air into radiant heat for air conditioning. Additionally, "Yukarira" does not generate airflow, which prevents the lifting of viruses and dust, contributing to infection prevention. It also provides gentle heating and cooling for those with dry skin or atopic conditions, as there is no direct wind impact. In terms of energy consumption costs, it is significantly more economical than conventional convective air conditioning, reducing cooling costs by approximately 34% and heating costs by an impressive 48%, making it wallet-friendly. 【Other Features】 - Less likely to cause low-temperature burns or heat shock, ensuring safety. - Maintenance-free for peace of mind. - Capable of serving all rooms (entire building). *For more details, please refer to the PDF document or feel free to contact us.*

• Floor heating system

"Yukarira" is a system that maintains a uniform temperature throughout the room by flowing warm and cool air across the entire floor, rather than using conventional convective air conditioning. It converts the air into radiant heat through panels, providing air conditioning. In terms of energy consumption costs, it is significantly more economical than traditional convective air conditioning, reducing cooling costs by approximately 34% and heating costs by an impressive 48%, making it budget-friendly. Additionally, since "Yukarira" does not generate airflow, it prevents the uplift of viruses and dust, contributing to infection prevention. Moreover, as there is no direct wind impact, it is gentle on the skin for those with dry skin or atopic conditions. 【Features】 ■ Comfortable without drafts due to radiant heating from the floor ■ Can accommodate entire rooms (or buildings) without temperature differences between rooms ■ Air conditioning that does not create airflow, considerate of the body ■ No maintenance required ★ We are currently offering materials that explain the benefits of Yukarira.

The "YSS System" is a system that utilizes joist steel and beam steel used in large spaces such as gymnasiums to achieve radiant air conditioning. The airflow that is ejected in contact with the floor only spreads on one side, resulting in a longer reach and a heat transfer to the floor material that is 2.5 to 5 times greater compared to when the airflow does not occur. In other words, it can effectively warm or cool the floor material. 【Features】 ■ Utilizes joist steel and beam steel used in large spaces such as gymnasiums ■ The airflow ejected in contact with the floor only spreads on one side ■ Heat transfer to the floor material is 2.5 to 5 times greater compared to when the airflow does not occur ■ Effectively warms or cools the floor material *For more details, please refer to the PDF document or feel free to contact us.
