The efficiency test was done to Daikin’s latest model, ZETAS which was launched in March 2021, to verify the imbedded streamer technology’s capability in reducing bacteria and eliminating unpleasant odor from within the air conditioner unit.
The streamer technology has been developed by Daikin Industries (Japan). In 2004, the technology was launched in the market with its highlight feature, the streamer discharge, that is capable of dissolving harmful substances in the air.
Streamer discharge is an air purifying technology that creates stable high-speed electrons – a technology that was hard to achieve at that time. Streamer’s ability to decompose matters with oxidation is higher than glow discharge. Moreover, when combined with the air’s molecule, these high-speed electrons can decompose matters with oxidation, allowing streamers to eliminate unpleasant orders, bacteria, and pollutants such as formaldehyde continuously and effectively.
Asst. Professor Dr. Prapat Pongkiatkul and the research team from the Environment Engineering Department, Faculty of Engineering of King Mongkut's University of Technology Thonburi tested the efficiency of streamer technology in Daikin ZETAS with bacteria sample collected from the fan coil unit and the drain tray of the air conditioner unit with unpleasant odor from a residential area in Thailand.
The bacteria sample was cultured and then embedded in a Daikin ZETAS, which was placed in an environment simulated from consumer’s household. The test confirms that streamer technology in Daikin ZETAS can deactivate 75%-99.96% of bacteria and fungus in the air conditioning unit within the first 8 hours of use. Daikin ZETAS can deactivate 99.9% of bacteria and fungus within the fourth day of use.
Mr. Akihisa Yokoyama says that the test result verifies streamer technology’s efficiency in Daikin ZETAS that it can help reduce unpleasant odor of air conditioner unit that is caused by bacteria and fungus. This technology sets a new benchmark for household air conditioner and strengthens Daikin’s philosophy of not only cooling down the temperature but also perfecting the air.
The MOU between Siam Daikin Sales Co., Ltd. and King Mongkut's University of Technology Thonburi elevates that standard of air conditioner industry and inspires manufacturers to further develop technologies to the new height and deliver quality products with advanced technology to the consumers.
