Evaporative Cooling System for Air Conditioning

Vapour compression systems are most widely used Air-conditioning and Food Refrigerating systems. Their drawbacks include large energy consumption due to the compressor and harming the atmosphere directly (due to leak of refrigerant gases) or indirectly (electricity to power these systems comes largely from thermal power plants). Evaporative cooling systems are an alternative to the vapour compression systems. It is a relatively old technology that is slowly gaining popularity thanks to

Evaporative cooling systems are eco-friendly because they work on the principle of evaporation of water to achieve cooling. But they are effective in dry climate only. Thus to tackle the cooling loads in humid climate, we can make use of Desiccant technology. Liquid desiccants are solutions of salts and water that dehumidify and cool the air by absorbing moisture from moist air. Earlier desiccant packed beds or wheels were used but liquid desiccants have a higher moisture absorption capacity. A cooling system is designed and fabricated that can achieve either dehumidification or humidification and cooling based upon concentration of salt used into the water. Aim: To design and manufacture an evaporative cooling system while implementing desiccant technology in minimum time with minimum cost.
