A study on reducing the energy demand of a liquid desiccant dehumidifier with a radiant panel system
Tae Ha Leigh, Dea Uk Shin, Goo Sang Joe, Min Gi Kim, Myoung Souk Yeo, Kwang Woo KimAbstract: In hot and humid regions, cooling load and latent load should be removed together. Recently, liquid desiccant dehumidification is suggested as an efficient method of latent load removal. However, for continuous liquid desiccant dehumidification, liquid desiccant should be regenerated and regeneration heat is required. In this study, radiant panel system is suggested as a cooling method. And a method to utilize the generated heat, during the chilled water making for radiant cooling system, for the regeneration of liquid desiccant is suggested. For the evaluation of the suggested method, the energy demands were simulated and compared. As a result of comparison analysis between the energy demands of the system that uses suggested method and system that uses liquid desiccant dehumidifier and radiant panel separately, 85% of energy demand for regenerating liquid desiccant was reduced and 35% of energy demand for producing chilled water needed in cooling was reduced when using suggested method. Totally 63% of energy demand of the system was reduced. Method to utilize the generated heat, during the chilled water making for radiant cooling system, for the regeneration of liquid desiccant will be very useful at hot and humid region that need cooling and dehumidification.
