Executive Officer, Group President,
Living Environment & Digital Media Equipment
The Living Environment & Digital Media Equipment Group focuses on the air-conditioning and refrigeration systems business, one of the growth-driving sectors at Mitsubishi Electric. In addition to expanding operations, we are pressing forward with proposals of total solutions using IoT and AI technologies as well as products within and outside the Mitsubishi Electric Group to realize life solutions for everyone, from workers to people at home, to live by their own values by taking advantage of a wide range of synergies in technologies and business operations as a general electric-appliance manufacturer.
As we expand business, we believe it is important to provide products and services that contribute simultaneously to achieving sustainability, safety, security, and comfort as well as to resolving social issues. Part of this includes supplying a broad range of environment-friendly systems and services for the home, office, and industry. These include air conditioners that produce less CO2 during use and our energy-saving EcoCute product lineup. Additionally, Mitsubishi Electric proposes solutions that aim to achieve energy savings by building systems as a whole in support of programs such as ZEH and ZEB, promoted by the Japanese government.
Meanwhile, as activities to reduce CO2 from production, the Living Environment & Digital Media Equipment Group is proactively introducing energy-saving products at production sites; namely, high-efficiency air-conditioners, heat-pump hot-water supply systems and LED lighting. We are also promoting energy-saving activities by improving productivity linked to just-in-time improvement activities based on e-F@ctory concepts.

Water heaters, ventilating fans and other products sold by Mitsubishi Electric incorporate various devices in order to simultaneously achieve improved energy-efficiency performance and maximum comfort. Such efforts were recognized by the Energy Conservation Center, Japan (ECCJ), and three Mitsubishi Electric products received honors in the Products and Business Models Category of the Fiscal 2021 Energy Conservation Grand Prize presented by the organization.

Lossnay® (the world’s first energy recovery ventilator to use heat-exchange technology), a system that eliminates air conditioner energy loss during ventilation, has a sales track record stretching back more than 50 years, and a wide lineup is offered for offices, tenant buildings, stores, schools, and various other buildings. Lossnay® creates a comfortable environment while ventilating in an energy-saving manner. Lossnay® also supports special environments with a moisture-proof model for pools, air-conditioned cultivation rooms, and refrigerators as well as a high-power deodorization cassette model for elderly care facilities and hospitals. In response to recent needs, it has been enhanced with a humidification function.
Demand for the ecodan series of air to water (ATW) heat pump hot water systems is rapidly increasing given the environmental regulations in place mainly in Europe, where hot water heating systems are generally used for heating. These systems conventionally employed a combustion system based primarily on a gas or oil boiler as the heat source equipment. By replacing such systems with ecodan, a heat pump hot water system which is a renewable energy solution, Mitsubishi Electric reduces CO2 emissions. We now lead the market with our lineup of products that are conscious of the global environment mainly in European countries.
ATW（Air to Water: Heat Pump Hot Water System）
The MILIE LED lighting brand name was coined from the words "Mitsubishi", "lighting", and "ecology". It expresses our desire to make positive contributions to Earth and society through LED lighting. The lineup has been expanded to include products for a wide variety of applications according to purposes and facilities. These include My Series LED base lights mainly for offices, GT Series high-ceiling LED base lights for factories, warehouses, and gymnasiums, AK Series LED spotlights for retail stores, the MILCO.NET and MILCO.S lighting control systems, which simultaneously achieve improved comfort and reduced power consumption, misola blue sky lighting that expresses a clear and bright blue sky with a sufficient feeling of depth and natural streaming in of sunlight, and more.

The EcoCute heat-pump hot-water supply system that uses air heat to efficiently boil water has further improved its energy-saving performance with the new model for fiscal 2021, which is equipped with a "thermo jacket tank"*1 as the hot water storage unit tank to improve thermal insulation. Consideration is given to the environment as well by adopting the split style for the urethane foam to make recycling easy. In addition, operation linked to a photovoltaic power generation system*2 based on weather forecasts facilitates effective use of the surplus power generated during daytime.
Moreover, with "kirariyu-keep,"*3 a new function that suppresses the proliferation of germs in bathwater, and "attaka-link,"*4 a function for linking operation to dressing room/bathroom heating, EcoCute improves cleanliness and comfort while achieving energy-saving performance.
We have developed technologies to automaically separate three types of plastics (i.e., PP, PS and ABS) used in home electrical products from a mixture of different materials originating from home appliances. We have also improved the identification of physical properties when separating materials, and are pressing forward with an original recycling system in which plastics recovered from home electrical appliances are recycled and used to manufacture our home electrical products.
