Abstract

Desiccant wheel system is a topic of research because of increased requirement in HVAC industry and dehumidification industry. Heat and mass transfer in order to remove water or other solvents is called drying process. By passing air over solid, semi-solid and liquid materials, humidity can be reduced. Using the desiccant process is only one of the cost-effective methods. Solid dehumidifier absorbs water using chemical absorption. A number of solid desiccant samples include: silica gel, natural zeolite, activated alumina and synthetic polymers. Desiccant is a hygrometer that is generally used as a drying agent in dryers and air conditioning systems. The job of desiccant is to remove moisture from the air to reduce the humidity of the surrounding air for people's comfort. After our dehumidifier becomes saturated, we put it under the dehumidification process by passing hot air in or-der to revive it and make the process continuous. Like all air conditioning systems, this device also has its own advantages and disadvantages. Its advantages include intermittent air drying with low energy consumption. Also, its disadvantages include low capacity in moisture absorption and pressure reduction. The result of this project indicates that the placement of absorbent layers perpendicular to the current has a significant effect on reducing the moisture content of the transient current, so that the moisture reduction when the layers are perpendicular is 3% greater than when the layers are parallel to the current.
