Abstract
In this paper, a model of liquid desiccant evaporative cooling system is presented and simulated. The objective of this paper is to reveal the effects of various parameters on thermodynamic performance and to show the optimal range of those parameters. These results show that the system performance is strongly influenced by the hot water temperature, the flow ratio of air to solution and ambient air relative humidity, followed by the hot water flow rate. And the optimal range of each influencing factor is determined as follows: hot water temperature and the value of ma/ms are adopted to be about 75â°C and 1âkgâ
kgâ1 respectively, while hot water flow rate will not be greater than 0.6âkgâ
sâ1 and the range of the relative humidity of the atmosphere is wide. The analysis of the exergy efficiency ratio shows that the regenerator (REG), dehumidifier (DEH) and the enthalpy exchanger (EX) in the system are the weak parts of the system.
