Product development focused on health, energy efficiency and high-quality environments

「技術開発においては、新製品として水冷HP式デュアル空調システムを開発し、八尾技術研究センターでは新冷媒対応、新機能を付加したモデルチェンジ、制御システムの高度化へ向けた開発検証を実施いたしました。」

「During the fiscal year's development activities, following the slim floor-mounted model developed in the previous fiscal year, the company developed the cold- and hot-water ceiling-concealed slim HVAC unit as a new product featuring a compact design based on its proprietary design. Compared with the previous product, this model reduces height by 24% (510→390mm) and achieves a 10% reduction in weight.」

「In technology development, the company is currently constructing a technology research center to accelerate further refinement of products emphasizing temperature and humidity control and products with a low environmental impact. R&D expenses for the interim accounting period amounted to ¥73.814 million. There were no significant changes in the status of the company's R&D activities during the interim accounting period.」

「During the fiscal year's development activities, the company released 3 new products equipped with the slanted, flat oval-tube heat exchanger, an elemental technology developed in the previous fiscal year and hereinafter referred to as the Slanted Flat Coil. The cold- and hot-water high-performance ceiling-concealed HVAC unit and the cold- and hot-water high-performance vertical HVAC unit feature a new design that significantly reduces the size of the HVAC units, delivering resource and energy savings and increasing the added value of cold- and hot-water HVAC systems.」

「R&D expenses for the cumulative third-quarter period amounted to ¥90.968 million. There were no significant changes in the status of the company's R&D activities during the cumulative third-quarter period.」

「R&D expenses for the cumulative second-quarter period amounted to ¥59.077 million. There were no significant changes in the status of the company's R&D activities during the cumulative second-quarter period.」

「R&D expenses for the cumulative first-quarter period amounted to ¥28.303 million. There were no significant changes in the status of the company's R&D activities during the cumulative first-quarter period.」

「The main development initiative during the fiscal year was the development of elemental technologies to advance the company's new concept, Natural ZEB HVAC. The newly developed slanted, flat oval-tube heat exchanger was created by redesigning the heat exchanger, a core component of an HVAC unit, in a slanted and slim form, and combining it with aluminum fins processed using proprietary techniques and oval copper tubes, with the aim of achieving both high air velocity in a compact design and low pressure loss.」

「R&D expenses for the cumulative third-quarter period amounted to ¥108.609 million. There were no significant changes in the status of the company's R&D activities during the cumulative third-quarter period.」

「R&D expenses for the cumulative second-quarter period amounted to ¥69.088 million. There were no significant changes in the status of the company's R&D activities during the cumulative second-quarter period.」

「R&D expenses for the cumulative first-quarter period amounted to ¥28.719 million. There were no significant changes in the status of the company's R&D activities during the cumulative first-quarter period.」

「Our principal development during the fiscal year was the launch of “Best UV Air,” a commercial air-purification unit that promotes the clean and wellness spaces we seek to create.」

「R&D expenses for the cumulative third-quarter period amounted to ¥86.293 million. There were no significant changes in the status of the company's R&D activities during the cumulative third-quarter period.」

「In product development, we continued to promote initiatives centered on “the transition from conventional comfortable air conditioning to health- and hygiene-oriented air conditioning,” including the joint development of “Best UV Air,” an air purifier installed in air-conditioning ducts that uses deep-ultraviolet light.」

「The company promoted development of the Best Airflow series, with consideration given to ventilation and health.」

「Based on the concept of contributing to the health of people and society, this system aims to create spaces where occupants can live comfortably and in good physical and mental health, and incorporates measures to enhance its effectiveness in preventing infectious diseases.」

「In new product development, the company is focusing on developing new HVAC systems that emphasize airflow design, radiant airflow control, ventilation and heat recovery, and humidity control as measures against infectious diseases. It is currently building experimental rooms for offices, hospitals and apartment buildings and conducting validation testing.」

「In response to growing awareness of air quality and ventilation, we strengthened proposals for ventilation-related products centered on outdoor air-handling units. In product development, we focused on developing a new air-conditioning system emphasizing radiant airflow control, humidity management, and ventilation as measures against infectious diseases.」
