【 摘 要 】

In the process of dehumidification of the solution, dehumidifier contacts with air directly to achieve the purpose of dehumidification, which is a very important part of air conditioning dehumidification system. Under different working conditions, the basic physical parameters of the liquid desiccant will change, which will have an important impact on the efficiency and performance of dehumidification. LiCl solution is widely used as a desiccant with many advantages such as high efficiency and safety. In this paper, the basic physical parameters of LiCl solution with high accuracy are summarized. Empirical formulas of saturation temperature, surface tension, density, dynamic viscosity, thermal conductivity, specific heat and dilution enthalpy of LiCl solution are summarized. The relationship between different physical properties and temperature, pressure and solution concentration is drawn. The corresponding data tables and graphs are drawn under different working conditions. This conclusion has developed a new idea for the research of desiccant solution, which provides a basis for follow-up research and in-depth research.
