Design and Analysis of Dehumidifier to Improve Air Quality

Abstract

Compressed air is used for obtaining brake application in which brake pipe and feed pipe run throughout the length of the coach. Brake pipe and feed pipe on consecutive coaches in the train are coupled to one another by means of respective hose couplings to form a continuous air passage from the locomotive to the rear end of the train. Compressed air is supplied to brake pipe and feed pipe from locomotive also the magnitude of braking force increases in steps with the corresponding reduction in brake pipe pressure. So due to brake binding and brake failures due to pressure drop and high moisture rate so there was need of dehumidifier because of less moisturized air. When passed to braking system it will help the braking system and there will be less brake binding and pressure failure in braking system so with the help of dehumidifier, we can reduce moisture content and pass dry air to the braking system and increase good braking effect and decrease maintenance. As per the result of dehumidifier we have decreased moisture content up to 81.08% and decreased maintenance life by 120 days also this dehumidifier is less small in size than the prior one. From obtained moisture content of 37%, we have decreased it to 7%. Also, it is more efficient to replace silica gel easily in this dehumidifier.
