| Abstract |
The purpose of this study was to compare the cooling and heating loads of liquid desiccant by maintaining the sump concentration in a liquid desiccant system. Case 1 is a liquid desiccant system with a dual sump based on solution exchange. Case 2 is a liquid desiccant system with membrane-based dual sump. Both cases are based on a dual sump, but the technologies used to maintain the concentration of solution in the sump differ. The concentration of the absorber and regenerator sumps in case 2 was similar to that of case 1. The results also indicated that case 2 required 71% lower cooling and heating load for solution than case 1 because the temperature of the absorber sump was lower and the temperature of the regenerator sump was higher. Therefore, case 2 saves energy for solution cooling and heating while maintaining dehumidification and solution regeneration. |
