Performance Evaluation of an Evaporative Type Air Cooler

Abstract

Evaporation serves as a natural cooling process. By applying the evaporative cooling principle to convert sensible heat into latent heat, evaporative cooling decreases the temperature of the air. Here, the idea of evaporative cooling is used to guide the work. The price of energy in all its forms is rising daily. It is now vital to consider alternative energy sources or to use alternative technologies to lessen energy use. Any business, home, or structure that uses an air conditioning system of any kind contributes to the production of waste that harms the environment. Environmentalists are aware of and concerned about their effects on ecological systems, living things, and the environment as a whole. This project involves working on a system that uses the evaporative cooling of water for direct air conditioning. On the basis of this idea, an air cooler that performs the same duties as an air conditioner is built at the expense of the air cooler. In contrast, dry and cold air is produced, but running costs are considerable because of expensive refrigerant, compression, and maintenance costs. Economical design and operation, humidity-free air, and lower running costs are all significant advantages of the evaporative air cooler system. Additionally, it has nothing to do with an issue like the thinning of the ozone layer. The technology has the ability to chill the area, lowering the temperature by 5 to 10 degrees Celsius. The objective of this project is to build a hybrid, cost-effective, and environmentally friendly system using the concepts of an air water cooler and a split air conditioner, using canvas as the construction material for the DC pump motor, AC fan, MIST maker, ESP32 micro-controller, LCD display, DHT11 temperature sensor, and PAD. Additionally, a smartphone app connected to Bluetooth allows for control of this device
