Aircosaver - Air Conditioning Energy Saving Device - Silver Box

Recently we also analysed a Chinese product which claims to save 25% to 35% of energy. We were quite amused once we figured out how this device is supposed to work. Take a look at the picture. The little silver box is not a temperature sensor but it is a heating(!) element. This little silver box is placed over the aircon unit’s thermostat sensor! The thermostat sensor is then heated up inside the silver box… We measured temperatures of up to 50 degrees celsius on the surface of the heating element. Go figure.
