- This paper details the design and fabrication of a portable air conditioner device with a self-cleaning system which can be set by the user depending on the desired schedule. The self-cleaning system cleans the evaporator and condenser of the air conditioner. The processing unit (a microcontroller) will determine if the cleaning function will commence by extracting data from the water level sensor located on the device’s water repository used for cleaning and from the user-defined timer. The self-cleaning system will not initialize if the microcontroller determines that there’s no water on the tank. Temperature sensoris used to detect the room temperature and two red-green-blue (RGB) light emitting diodes(LEDs) as indicators. Optimum settings on the water volume and sprinkler’s hole diameter were determined in order to satisfactorily clean the evaporator and condenser in 102 seconds. On an ideal room size for a 1⁄2 horsepower AC system, the target temperature of 25°C was reached within 8-14 minutes.

Keywords : Self-cleaning device, portable air conditioning system.
