Abstract
The desiccant wheel system is a topic of research because of increased requirements in the HVAC industry and dehumidification industry. Heat and mass transfer to remove water or other solvents is called the drying process. By passing air over solid, semi-solid and liquid materials, humidity can be reduced. Air conditioning is a process that collects the hot air of the desired environment, cools it with a refrigerant and then blows the cooled air into the desired environment. Using the desiccant process is the only cost-effective method. 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 function of the desiccant is to remove moisture from the air to reduce the humidity of the surrounding air for people's comfort. After the dehumidifier becomes saturated, it is put under the dehumidification process by passing hot air to revive it and make the process continuous. Like all air conditioning systems, this device also has its advantages and disadvantages. Its advantages include intermittent air drying with low energy consumption. Furthermore, its benefits include low capacity in moisture absorption and pressure reduction. Using this method affects the efficiency of the system and the desiccant must be cooled after complete drying.
