The BLAUX Portable AC uses Peltier Effect for cooling the air. it's a thermoelectric process that uses the voltage difference of two electrical junctions to vary the temperature of air. The cold air is accumulated at one junction and is then able to be used for cooling. While, at the top of the day, it's an "air conditioner", however, it can actually do far more than that. The BLAUX Portable AC also can be used as a heater because of the thermoelectric effect that we talked about earlier. the recent air is accumulated at the opposite junction, which may be used for heating purposes. aside from that one also can use it as a humidifier or simply as a lover if they desire. The BLAUX Portable AC features a fan to direct the cold air generated inside to the surface . The fan has three speeds that allow it to be used specifically as required .
