Résumé

This paper proposed a novel temperature and humidity independent control air-conditioning system based on liquid desiccant, in which liquid desiccant with low-concentration and low-temperature was used in air dehumidification, and the condensation heat could meet the need of the regeneration of desiccant solution. A validated mathematical model was used to investigate the performance of the novel system under different operation conditions. The results showed that under typical indoor condition in Nanjing summer, mass concentration range of 25.39%~26.88% was suggested in the dehumidification process using LiCl-H2O, and the relevant temperature range was around 17oC~19oC. The effects of the ratios of indoor sensible load to latent load on the system performance were discussed, and performance comparisons showed that COPsys of the system was 13.6%~116.1% more than that of the conventional system. For this new system, 60%:40%~40%:60% were reasonable range for dissipation distribution of condensation heat between the solution-cooled condenser and air-cooled condenser.
