Retrofit System Wins Minister’s Prize, the Ministry of Economy, Trade and Industry in 2016 Energy Conservation Grand Prize

Daikin’s Retrofit System is the first of its kind in the world. Building air conditioning systems installed at least five years or longer can have their compressors and energy-efficient control software replaced with the latest specification items. Besides retaining the benefits of conventional maintenance processes, simply replacing key components can reduce power consumption by up to 15%. There are approximately 1 million Daikin multi-split type air conditioners for commercial buildings installed around the world that can take advantage of the Retrofit System, which means we can expect to see reductions of greenhouse gas emissions through implementation of this service.

Daikin Uses IoT to Capture Chairman’s Prize, Energy Conservation Center, Japan, in FY2016 Energy Conservation Grand Prize

Many senior citizens’ homes are faced with the problem of having to operate all air conditioners in a building around the clock because, despite wanting to save energy, they must ensure that their residents are comfortable and they cannot spend time carefully operating air conditioners on a daily basis. Daikin used IoT in a proprietary energy management system (EMS) for a senior citizens’ home, which ensures that residents are comfortable while at the same time saving up to 33% in power consumption.

In this case, Daikin incorporated a remote monitoring system to follow the air conditioners via the internet. Thanks to operational data from the air conditioners and feedback from the senior citizens’ home’s staff, the system can learn what needs to be improved from current usage, and it can automate things like daily temperature settings and the switching on and off of air conditioners. In addition, through remote operation, Daikin can make improvements in operational settings of the air conditioners, allowing for speedy response to customer requests.

Energy-efficient Hybrid Hydraulic Unit EcoRich Contributes to Energy Efficiency and CO2 Emission Reductions in Factories

EcoRich, a hydraulic unit that moves the hydraulic control shaft of machine tools in factories and other facilities, was developed in 1999 and was the world’s first such product to combine hydraulics technology and air conditioner motor inverter technology. It achieved approximately 50% lower energy consumption compared to Daikin’s previous product.

In 2016, this product underwent a model change with the incorporation of high-efficiency IPM motor, resulting in a 30% decrease in energy consumption over the previous model. In addition, it kept oil temperature rise to no more than 5°C, which meant a reduction in the effect of heat in machinery using hydraulic units and an improvement in processing precision.

UX Series and Other Residential Multi-split-type Air Conditioners that Connect with Floor Heating Awarded Chairman’s Prize, Energy Conservation Center, Japan, in FY2016 Energy Conservation Grand Prize

With today’s aging society, homes need to be able to handle increasing problems, such as ensuring consistent heating throughout all rooms to reduce the shock of extreme temperature differences. Our residential multi-split-type air conditioners, with just one outdoor unit, can connect to up to five heaters, including indoor units and floor heaters, allowing a variety of combinations with indoor units to match the user’s lifestyle.

At startup, there is a large difference in temperature between the room and the air conditioner’s set temperature, and to quickly bring the room to a comfortable temperature, the air conditioner and floor heater operate simultaneously. Here, residential multi-split-type air conditioners allow high-efficiency operation using the heat exchangers of both the air conditioner and the floor heater. Compared with operating just the floor unit, it takes less than half the time to warm up the entire room, and it reduces power consumption by 33%. And by using just one outdoor unit to control multiple air conditioners inside the house, users get reduced energy use throughout the entire home.

Once the room reaches the air conditioner’s set temperature, operation reverts to the lowest necessary level, and by using mainly floor heaters that employ low-temperature water, users can maintain both energy efficiency and comfort. When room temperature drops, the air conditioner compensates to maintain temperature. This product can bring out greater air conditioning efficiency in today’s homes, which are becoming increasingly airtight and insulated.

In October 2016, we expanded our lineup with the introduction of the UX Series residential multi-split-type air conditioners, which offer an elegant design that blends in with home interiors. This helps users meet their desire for products that enhance the look of their homes.

Providing Solutions to Reduce Environmental Impact

Energy Efficiency throughout Entire Buildings and Cities

The Daikin Group uses environmental technologies in areas such as inverters and refrigerants to provide solutions for not just reducing the environmental impact of individual air conditioners but also for reducing the impact throughout an entire building or city.

Energy management systems (EMS) are an effective way to save energy while keeping a building comfortable. Japan’s Ministry of Economy, Trade and Industry (METI) is conducting a project to hasten the spread of EMS, and in April 2012 Daikin Industries, Ltd. was selected as a BEMS aggregator under this project: a company charged with managing a BEMS. Under this project, we are picking up the pace at which we are providing a system that can achieve precise demand control and thus give both a comfortable building temperature and energy-saving operation; and that can use weather forecast data to automatically set equipment so that it operates in the most energy-efficient and energy-saving manner possible.

This project was incorporated as a scheme under the category of using energy management companies of Japan’s Subsidy for Companies Rationalizing the Use of Energy, Etc., which began in fiscal 2014. In fiscal 2016, we installed 6 systems under this scheme.

Since fiscal 2013, Daikin Industries, Ltd. has been selected as a diagnosis organization for projects such as the Ministry of the Environment’s Model Project for Effective Renovation Toward Promoting Green Buildings. For customers who use our Air Conditioning Network Service System for remote monitoring of air conditioners, we use operational data as a basis for improving their air conditioning operation and providing energy-efficient services. In fiscal 2016, we provided energy-efficiency diagnostic services for a cumulative total of 220 projects, resulting in savings for customers of approximately 16,300,000 kWh per year, and a cumulative total of 34,300,000 kWh so far.

Between fiscal 2014 and 2016, along with Hitachi, Ltd. and Mizuho Bank, Ltd., we participated in the Smart Communities Project in Greater Manchester, UK, implemented by Japan’s New Energy Development Organization (NEDO). Under this project, heating systems in 550 homes were converted from combustion-type boilers and electric heaters to heat-pump models to reduce energy consumption. We also conducted a demonstration project for a potential business model using automated demand response technology*, in which the electricity usage at multiple residences is aggregated, operation is automatically adjusted based on the demand situation, and excess electricity is generated.

* Automated demand response technology: Technology in which automated operation allows for the adjustment of power consumption by air conditioners and other appliances.
