Problems solved by technology

Although the internal cooling dehumidification structure is adopted in the prior art, which can suppress the temperature rise of the solution during the dehumidification process, the existing internal cooling dehumidifiers all use external refrigerants to send the dehumidifier into the dehumidifier to cool the solution, which has the following disadvantages : 1) The manufacturing requirements are high and the structure is complicated. The setting of the cooling coil reduces the heat and mass exchange area per unit volume of the filler, and the total dehumidification capacity is limited; 2) The heat exchange between the refrigerant and the solution occurs in the form of sensible heat exchange. On the one hand: to enhance the cooling effect, measures such as increasing the flow rate of the refrigerant, lowering the temperature of the refrigerant, or enhancing the heat transfer on the surface of the heat exchanger must be taken; on the other hand: these measures will increase the energy consumption of the system, and the temperature of the refrigerant Low and may lead to crystallization of the solution, limiting the effect of internal cooling
