Hitachi room air conditioner “Shirokuma-kun” awarded “FY2019 Energy Conservation Grand Prize” of Japan
The Energy Conservation Center, Japan revealed the winners of the Fiscal Year (FY) 2019 Energy Conservation Grand Prize of Japan. Rooom air conditioner “Shirokuma-kun” Premium X Series, launched in the Japan market this autumn, received the FY2019 Energy Conservation Grand Prize, Product & Business Model Category, ECCJ Chairman’s Award (The Energy Conservation Center, Japan Chairman’s Award).

The “Shirokuma-kun” Premium X Series room air conditioner comes with the following outstanding features: “Frost Wash” and “Fan Robo” features for the indoor unit, and the industry’s first “outdoor unit heat exchanger auto cleaning” feature.

Engineers have consistently been focusing on how to maintain cleanliness in the interior of air conditioner units. This has led them to develop unique features within the industry, including the indoor unit heat exchanger auto clean “Frost Wash” which rapidly removing dirt and grease from the indoor unit heat exchanger by automatically freezing the exchanger and then rapidly melting the frozen layer which is formed, and the fan auto clean “Fan Robo.” The “outdoor unit heat exchanger auto cleaning feature” blows dust out and away from the unit’s interior by reversing fan rotation and follows with a “Frost Wash” clean. These cleaning feature innovations contribute to the suppression of airflow reduction and reduction of wasted electricity. In addition, the indoor unit comes in a compact size, less than 800 millimeters in total width, while achieving greater energy-saving performance. It was these innovations that led the “Shirokuma-kun” Primium X Series to be awarded the prize.

Johnson Controls-Hitachi Air Conditioning continues to pursue energy efficiency for the further advancement of air conditioning technology.
