3R & Repair

Stressing Effective Use of Resources in Design

Daikin Industries, Ltd. strives to use resources as effectively as possible by carrying out the 3Rs-reducing, reusing, and recycling-along with repairing under its 3R & Repair initiative.

This initiative plays a key role in our product design and development. Based on product assessment, we design and develop products that are smaller and lighter, have fewer numbers of parts and screws, and that use materials and construction that make them easy to maintain, separate, and recycle.

3R & Repair: Approach

Reduce Make products smaller and lighter, Use recycled materials
Reuse Use parts from end-of-life products
Recycle Development

Design products that are easy to separate and recycle

  • Use plastics that are easy to recycle
  • Indicate the materials used
  • Construct products that are easy to disassemble
After use Recycle end-of-life products
Repair Development Design products that are easy to maintain
After disposal Have a repair support system that contributes to long-lasting products

Recycling

Designing Products for Easy Disassembly

Product design stresses 3R & Repair based on product assessment. Since 1997, we have designed products so that their construction makes them easy to disassemble.

In fiscal 2014, we equipped the FIVE STAR ZEAS air conditioner for stores and offices with an all-aluminum micro channel heat exchanger. This makes it easier to separate the material during disassembly compared to products using conventional cloth heat exchangers. Office air conditioners and the S-round flow Cassette for stores and offices, which were released in February 2016, use an ODM motor. This has eliminated the need for adhesive on the antivibration rubber on the turbo fan boss, making it easy to remove plastic, steel, and rubber for recycling.

Reducing

Maker Smaller and Lighter Products that are Still Energy Efficient

Making products smaller and lighter means they will use fewer resources. When making air conditioners, for each product we set weight reduction targets for both the entire product and its components. However, it is technically difficult to achieve this without sacrificing energy efficiency. If making it smaller and lighter means that it consumes more energy, then the product's environmental performance throughout the entire lifecycle has not yet been improved.

When Daikin Industries, Ltd. develops new products, we establish weight reduction targets for each product on the condition that the annual performance factor (APF) does not decrease.

In fiscal 2015, we reduced by 1 kg each the weight of the FIVE STAR ZEAS (4–6 HP) and the New Eco-ZEAS (4-, 5-, 6-HP classes) air conditioner for stores and offices. In addition, we were able to raise the APF of the new Urusara 7-Series residential air conditioners (2.8, 3.6, 4.0, 5.6 kW) while at the same time reducing by 2 kg the weight of the outdoor units. Air purifiers that we released in fiscal 2015 take up 30% less installation space than their predecessor products and are 14% smaller and lighter. .

Product Packaging Weight Reduced by 5% Since Fiscal 2010

We set a target of reducing the amount of packaging for air conditioning products by 5% in fiscal 2015 compared to fiscal 2010. We had previously switched packaging material from wood to thin cardboard, and reduced the number of packaging parts. In fiscal 2015, we changed the packaging shape to accommodate the change from horizontal storage to vertical storage and were thus able to achieve our reduction target.

Because changing the packaging shape also necessitates a change in the production process, we are aiming to further reduce the amount of packaging material through close cooperation among the packaging, manufacturing, and design divisions.

Daikin Awarded by Japan Packaging Institute for 50% Reduction in Packaging of Ceiling Mounted Cassette Type Air Conditioners

We changed the packaging shape of our air conditioners to accommodate the change from horizontal storage to vertical storage, thus reducing storage space needed and reducing the size of buffer material, resulting in 50% less packaging material and a 25% improvement in storage efficiency. By developing a thin bottom tray that combines the tray and buffer material, we were able to dramatically improve the efficiency of packaging work.

For these efforts, Daikin received an Electric Equipment Packaging Award in the Good Packaging category in the 2015 Japan Packaging Contest sponsored by the Japan Packaging Institute.

Reusing

Repair and Reusing Parts that have Already Been Replaced

In the Daikin Group, we try to use resources efficiently. We take parts that have already been replaced and that contain multiple components, such as printed circuit boards, and we repair any malfunctions or replace the worn-out components. These parts (the printed circuit board, for example) are then tested for quality by ensuring that they are functioning properly and, with the customer's permission, are used as replacement parts when performing repair on a product.

Reinforcing the Global Repair System

Making products that last longer means that fewer resources are used. To this end, the Daikin Group is strengthening its repair system by establishing service outlets around the world to take customer repair requests and questions and enquiries regarding products.

In Japan, the Daikin Contact Center is open 24 hours a day, every day of the year to take inquiries. We will continue to strive for even greater customer satisfaction by improving the technical expertise and etiquette of our service engineers through an engineer certification system. To ensure that customers phoning with repair requests get prompt responses, we have a database of past repair cases, practical know-how, and rules of thumb that Contact Center staff can access immediately. By asking for necessary information and providing appropriate instructions to customers over the phone, we avoid unnecessary service calls, thus improving work efficiency and boosting customer satisfaction.

As Daikin products are sold in an increasing number of countries, we are working to strengthen our service network in each country. By introducing service management systems, we are making workflow more efficient and providing more high-quality and transparent service in every phase of customer interaction including through our service engineers and our partner companies.

Recycling Residential Air Conditioners

Daikin Achieves Recycling Ratio of 90%, Well above Obligations under Home Appliance Recycling Law

The Home Appliance Recycling Law obligates manufacturers to recycle at least 80% of the material from their own air conditioners as well as recover and then reuse or destroy refrigerants.

In fiscal 2015, we recovered about 250,000 products totaling 10,369 tons. The recycling ratio was 90% and the amount of fluorocarbons recovered was 160 tons.
