castor wheels, making it easier to manoeuvre the cooler, and use them wherever necessary.

The domestic air coolers, which are cost effective, play a positive role in providing human comfort during atmospheric condition. However the performance is dissatisfactory where-ever high humid zones are encountered. This project paves for further evolution in areas where the performance of air cooler can be enhanced using an exchange system comprising serpentine aluminium tubes and and force convected using exhaust fan. This enables the eliminating of rise in humidity that typically encountered within the conventional air cooler. The target of this development is to supply cooled air to take care of the area where dry atmospheric temperature surge to higher value.

Traditional desert coolers used cooling pads, or packing material and artificial fibres because the cooling medium. With lower water retention capability and higher maintenance, these cooling pads were inefficient and sometimes resulted in large amounts of water being consumed. Furthermore, the cooling pads made of aspen wood were also fragile, and would often get damaged during the installation. However, the trendy air-cooling systems use cellulose cooling pads and eco-cool cooling pads, which have higher water retention capability. This ensures better evaporation, thereby increasing the cooler's cooling efficiency. The modern air coolers also include an cube tray, which could be a significant upgrade from the standard desert coolers. This feature allows customers to feature icy water to the tank, thereby enabling quick and efficient cooling.

1. Introduction 1.1 Introduction of indirect evaporation process

The modern air cooler models also are sleek and trendy, a stark contrast from the standard desert coolers. Furthermore, by adding digital features, such as the digital control board, the trendy coolers offer greater convenience and fan control. Air cooling systems today also include remote, giving customers quick access to the settings. This ensures that you simply can control the speed of the fan with ease, without having to vary the settings manually.

Indirect evaporative coolers are often utilized to cool down air or other fluid with wet surface heat exchangers. The surface of the cooling air passages is wetted by spray water (also named recirculation water), so water film evaporates into the cooling air and reduces the temperature of the wetted surface. The primary air or other process fluid flows within the alternative passages and is cooled by indirect contact with the spray water film through the separating wall of the warmth exchangers

1.3 Working Principle

1.2 Application of modern air cooler

Indirect evaporative cooling works on the identical principle as direct evaporative cooling lowering air temperature by water Evaporation. The major difference in an indirect system is that it uses an device to chill the air supplied to the working space. As hot air passes over these tubes, its sensible heat is removed. After passing over the tubes, the cool,dry is delivered to living space.It not only lowers down dry bulb temperature but wet bulb temperature likewise. Indirect cooling find application where low humid but 100% fresh air is required for cooling.

Traditionally, air coolers are preferred to air conditioners in places with less humidity.With air coolers costing significantly but what an AC costs, while also circulating fresh air, the evaporation or desert coolers became the primary choice for purchasers, as summer approached. Traditional desert coolers, which are larger in size and need anywhere between 30-60 litres, had to be fixed near a window. Unlike modern air coolers, these desert coolers weren't portable and required either a stand or amount to for placement. Also referred to as outdoor coolers, desert coolers are suited for medium to large-
