Commercialization and adoption of energy-saving products and low-carbon technologies

「The company enhanced the performance of the floor-standing “Fresh Cool” outdoor air treatment unit, mainly for gymnasiums and factories, with an airflow rate of 1000CMH, so that it can provide sufficient cooling performance even during periods of high summer temperatures. It launched a new model in February 2026 that uses an all-fresh-air system, heating and cooling using only outdoor air.」

「“Fresh Cool,” an air-cooled integrated air-conditioning system for gymnasiums that provides ventilation and was launched last fiscal year, began deliveries during the current fiscal year. Development of these newly developed products is continuing with the aim of commercializing them during fiscal 2025–2027. For existing products, the company is developing improved refrigerants with lower global warming potential (GWP) values across all models to enhance environmental performance, and plans to commercialize 5 models in fiscal 2025.」

「Of the 6 models, development was completed on the main air-conditioning unit and dedicated air-supply unit of “Fresh Cool,” an air-cooled integrated air-conditioning system for gymnasiums that provides ventilation, and the product was launched during the current consolidated fiscal year. Development of the other 5 models is continuing with the aim of commercializing them during the fiscal years ending March 2026 to March 2027. For existing products, the company began developing improved refrigerants to enhance environmental performance. During the current fiscal year, it developed one model converted to a non-fluorocarbon refrigerant and began selling it as the first commercial air-conditioning unit to use a non-fluorocarbon refrigerant.」

「During the current fiscal year, the company began expanding the product lineup of the outdoor air treatment unit and developing monitoring equipment and energy-generation units to be used with it, and is proceeding toward the start of sales in fiscal 2024.」

「To address the conversion of buildings to ZEBs and demand for ventilation equipment during the COVID-19 pandemic, the company developed and began selling a “low-humidity outdoor air treatment unit.” Although it uses a cooling dehumidification system offering high dehumidification precision, it does not require low-temperature chilled water and incorporates a proprietary heat pump module that can use high-temperature chilled water, which is efficient to produce, and groundwater, a renewable energy source, as its primary heat sources.」

「The technology has been installed at a cumulative total of 9 properties. In parallel, the company worked with equipment manufacturers and others through the Aluminum Piping Equipment Association (APEA) to prepare technical materials for adopting aluminum refrigerant piping. It also prepared installation guidelines summarizing points to note when installing aluminum refrigerant piping.」

「The company developed an aluminum refrigerant piping installation technology that is one-third the weight of copper piping, less expensive and easy to recycle.」

「From July 2015, the company launched the full-scale rollout of “WINDS-Ⅲ,” a new dehumidifier for dry rooms used in the manufacture of lithium-ion batteries, organic EL devices and other products. By effectively using surplus waste heat from factories and waste heat from heat pumps, the system achieves annual energy savings of up to 60%. In August 2015, technology jointly developed with NTT DATA INTELLILINK CORPORATION, Osaka University and Advanced Telecommunications Research Institute International achieved a 70% energy-saving rate through the world’s first coordinated control technology and received the Environment Minister’s Award under the Awards for Contributions to Industry-Academia-Government Collaboration sponsored by the Cabinet Office.」
