Panasonic Unveils Air Conditioners that Clean Automatically

Panasonic, the leading brand by which Matsushita Electric Industrial Co., Ltd. is known, unveiled its latest air conditioners featuring a new anti-bacterial system and an advanced automatic filter cleaning system. The new systems maintain a germ-free environment and require no cleaning of filters. The X Series air conditioners include 11 new models and will be available in Japan starting Dec. 21.

The new split-type air conditioners reportedly feature the world's first anti-bacterial system consisting of an anti-bacterial heat exchanger, an ion-generating air purifier and filters that stay clean for 10 years. The exchanger eliminates germs during cooling and heating operations and inhibits the growth of mold that can cause an unpleasant odor. The fins of the indoor unit of the newly-developed heat exchanger are coated with resin containing a metallic anti-bacterial agent. By adjusting the amount of coating resin and the amount of the agent emitted, the anti-bacterial effect will last over 10 years.

According to the company, it has charged the entire surface of the filters on the face of the unit and placed an ion emitter near the air outlet. The emitter discharges a large amount of negative ions that electrically charge dust, mold, pollen, and other particles in the air. These are collected by the positively charged filters. The micro-mesh filters are 40 percent finer and have 50-percent greater dust collecting power than previous models, effectively preventing particles entering the unit. In addition, innovative air filters use zeolite and transition metal system catalysts to give them self-renewing deodorizing capability. Unlike conventional air conditioners, the new models are free of interior electrodes, which contribute to the "once in 10 years" maintenance.

Panasonic has advanced its automatic filter cleaning system that was well received when introduced in January 2005. The current system has 60 percent more dust collecting power, resulting in reductions in the filter cleaning time of 30 percent. It is also equipped with a controller that adjusts cleaning frequency according to operation hours, the amount of dust collected and the condition of the air in the room.

Large louvers on the left and right sides of the air outlet increase the horizontal air flow by 10 percent reportedly pushing more warm air lower in the room. This increases the comfort area five fold, with temperatures at least 25 degrees centigrade at 10 cm from the floor. This also saves energy by 10 percent over previous models with increased heating efficiency. The cleaning system will also be incorporated into the EX and AX Series air conditioners.
