In January 2009 Toshiba Air Conditioning won the Japanese Minister of Economy, Trade and Industry Prize for its light commercial ‘Super Power Eco Cube’ air conditioner series (named the Super Digital Inverter 4 series for overseas market) and the Chairman of Energy Conservation Center Prize for its residential ‘DAISEIKAI’ PDR air conditioner series (named the Super DAISEIKAI for overseas) in the 19th Energy Conservation Grand Prize Program.  The program’s objective is to energy saving equipment and systems for 2008 and  is sponsored by the Japanese Ministry of Economy, Trade and Industry (METI). The award winners were highly rated for excellent energy saving technologies in the store, office and residential air conditioner sectors.

Toshiba’s residential ‘DAISEIKAI’ air conditioning system has won this award in two consecutive years.

Reducing CO2 emissions in the commercial and residential sectors has become a key priority.   The energy consumption of air conditioning systems in retail stores, offices and homes accounts for about 30% of the total energy consumption of the building, it is increasingly important to achieve further energy savings in the field of air conditioning. Toshiba Air Conditioning has promoted energy savings by laying emphasis on the development of components that result in the improvement of the air conditioning system in terms of both performance and operating efficiency.  Maintaining a stable temperature and operation improves the energy consumption level.

All models in the Super Power Eco Cube series have attained the world’s best class (JIS B8616) annual performance factor. The main features are as follows:

(1)10 rps Economy Drive Control function which greatly contributes to a reduction in running cost
This function causes the outdoor unit’s DC twin rotary compressor to run at an ultra low speed of 10 rps. It enhances energy efficiency by changing intermittent operation which tends to occur under low load or when the room temperature reaches the preset value and operation stabilises, over to continuous operation.

(2)Self Cleaning function
 This enables the 4-way cassette ceiling type to maintain energy efficiency at the time of purchase for a long time.

(3)In order to facilitate the spread of space heating with a heat pump, the new models have been improved so that they can perform space heating even when the outside temperature is as low as -20^｡C.

The award winning Super Power Eco Cube series models are also sold overseas under the product name of Super Digital Inverter 4 series with a full lineup of 1.5, 1.7, 2, 3, 4 and 5 hp.

The ‘DAISEIKAI’ PDR series is top-class for energy efficiency in the air conditioning industry.

(1)This series has incorporated Toshiba’s own Dual stage compressor which operates at high efficiency over the entire capacity range from large capacity at the start of operation to small capacity when room temperature has stabilised. The new models have enabled electric power saving operation that requires such small electric power similar to an electric bulb under low cooling load or when the room temperature reaches the preset value and operation stabilizes.

(2)The new models for the Japanese market have adopted the industry’s first ‘Energy Monitor’ that shows visually the electric power consumption, the electricity costs and the operation condition.

(3)The new series has incorporated a new air purifier that removes airborne dust and pollen using a plasma ion charger and a hybrid arc heat exchanger with different diameters.

From February 2009, the company began shipping the DAISEIKAI PDR series which won the Chairman of Energy Conservation Center Prize to overseas markets centering on the European countries under the name Super DAISEIKAI.

These awards demonstrate Toshiba commitment to innovation and the development of technology that minimizes the impact on the environment and that delivers tangible energy saving benefits to the end user.
