Study on model of household split air conditioning solution dehumidifier

Liquid desiccant technology in central air conditioning system is very promising, however, rare researchers proposed to carry out it on household liquid desiccant air conditioner. In this paper, a two-dimensional heat and mass transfer theoretical model of cross flow dehumidifier for household split air conditioner has been established, and it is shown that the model established has a good accuracy and the relative error is less than 3.72% by comparing the simulation results with the experimental data in the literature. Based on the model, a series of experiments are conducted and the experiment data is adopted to fit the correlation formula of NTUm and Le. The results show that the model established has a good reaction to the actual situation. Furthermore, the influence of air, solution inlet conditions on the dehumidification performance of the system has been discussed in the paper.
