Abstract: A water making device includes a cooling process and heating process to generate water from air. The water making device includes a refrigerant assembly to cool down the air within the structure of the device. After reaching a specified temperature, air is let into the device using an air controller. A frost portion is formed inside the water making device. The cooling process finishes when the frost portion is at a specified thickness. A heating process uses a resistance surrounding the interior of the water making device to circulate hot air to melt the frost portion. Water droplets are generated and collected. The cooling process starts again upon completion of the heating process.
