Design and fabrication of portable mini air cooler

The need for air coolers has increased in recent years, as global temperatures have become unpredictable. The necessity for an air cooler is critical for people who live or work in cities, to have a pleasant location to work or live in hot weather. Unlike standard air conditioners which have the compressor unit to keep the air cool, bulkiness of the inside and outdoor unit and complicated to install, these coolers use evaporative cooling technology, which draws in heated air, passes it through a moistened filter, and then releases a stream of cold, humidified air into the surrounding area. This method not only reduces the ambient temperature but also adds moisture to the air, reducing dryness and increasing comfort, particularly in arid conditions. Thus, the main objective of this project is to develop a compact and lightweight 3 in 1 cooling device that is capable to humidified, purify and cooled the air in the area without the complex installation like the standard air conditioner. Furthermore, this mini air cooler can easily be portable and suitable for use in various environments, with its own power source and rechargeable battery, allowing the user to bring the product anywhere. In conclusion, portable mini air coolers are a versatile and efficient alternative for personal cooling, cleaning the air and humidity. Their small size, internal energy, and improved functions make them useful companions for anyone looking for comfort and relief from the heat in a variety of indoor and outdoor locations.
