Development and Market Launch of High-Efficiency, Energy-Saving Products

「For large-building air-conditioning and replacement projects, we launched the compact Air Joy (26A-AJ) air-conditioning unit, which reduces installation space by approximately 21% and annual power consumption by approximately 20% compared with conventional models, as well as the Fan Coil Unit Me series, which uses high-efficiency DC motors and helps reduce power consumption and CO2 emissions.」

「To help save energy and reduce CO₂ emissions, we developed a heat exchanger with improved heat-exchange efficiency compared with conventional models and began offering it to the market. We are also expanding the lineup of high-efficiency fans.」

「We are constructing a comprehensive air-conditioning test building to conduct validation testing of air-conditioning equipment for data centers and high-volume heat exchangers, and to support the development of heat-pump air-conditioning equipment. Operations are expected to begin on a phased basis from June 2024.」

「In our research into core technologies, we are expanding the range of high-efficiency fans and heat exchangers with the aim of saving energy and reducing CO2 emissions.」

「To address opportunities arising from climate change, we are primarily promoting sales expansion of central air-conditioning systems that use less greenhouse gas and highly energy-efficient heat-pump air-conditioning systems,」

「In the heat-pump air-conditioning series, we redesigned the model of the separate outdoor unit and added comfort-enhancing functions to the integrated outdoor-unit heat-pump air-conditioning unit, Oqugeo. Regarding research into core technologies, we are expanding the range of applicable equipment incorporating high-efficiency fans and heat exchangers as energy-saving and environmental technology products.」

「Expand the product lineup of heat-pump air-conditioning equipment.」

「We are developing sales of Healthy Air Conditioning®, which removes bacteria and viruses from the air, while conducting demonstration tests of disinfection systems for large spaces,」

「Following the COVID-19 pandemic and the renewed recognition of the importance of ventilation, we worked to develop sales for new demand, including improvements to air-conditioning equipment and additional installations of Healthy Air Conditioning®, which removes bacteria and viruses from the air.」

「Regarding research into core technologies, development of fans and heat exchangers (coils) aimed at higher efficiency and greater compactness has been completed. We are currently working with our manufacturing plants to prepare for production.」

「For our core air-conditioning products, we developed a new heat-pump air-conditioning unit with greater design flexibility and enhanced basic performance, as well as a high-sensible-heat direct-expansion air-conditioning unit optimized for data centers and capable of managing temperature and humidity.」

「For our core air-conditioning products, we are developing heat-pump air-conditioning equipment using gas refrigerants and health air-conditioning systems that remove bacteria and viruses present in the air at hospitals and care facilities through irradiation with powerful germicidal rays, in preparation for starting order-taking activities this autumn.」

「With regard to research and development, we have continued to focus on elemental technology development aimed at further improving the efficiency and compactness of the fans and coils (heat exchangers), which are key components of air-conditioning units, and have now progressed to the stage of testing actual equipment for practical application.」

「We released the new AJDD-type air-conditioning unit, which further expanded the model lineup of the AS Guide and Custom Runner, the key high-efficiency, energy-saving components of the AJEC-type air-conditioning unit, which received the Energy Conservation Grand Prize in fiscal 2014. We also newly developed a passive chilled beam that combines the radiation of cool air generated by a cooling device installed above the ceiling with the cool air released into the room.」
