As a humidity control system, the solid desiccant regeneration technology has the problems of high regeneration temperature requirement, difficult regeneration and the like, so that the solution dehumidification technology is more and more widely applied.

The working principle of the dehumidification system provided by the application is described in detail as follows:
fresh air (air to be processed) firstly enters a primary dehumidification subsystem and is subjected to a heat and mass exchange process with a dehumidification solution flowing down from the top of a primary dehumidifier 7; the low-temperature chilled water flowing out of the evaporation heat exchanger 29 in the absorption heat pump subsystem flows in a heat exchange copper pipe in the primary dehumidifier 7, and the dehumidification solution flowing down from the top is cooled, so that heat in the heat-mass exchange process of the dehumidification solution and air is taken away, and the solution dehumidification capacity in the primary dehumidification subsystem is enhanced. The primarily treated fresh air enters the secondary dehumidification subsystem again and is subjected to a heat and mass exchange process with a dehumidification solution flowing down from the top of the secondary dehumidifier 3; refrigerant evaporates the phase transition in the built-in heat transfer copper pipe of second grade dehumidifier 3 among the compression heat pump subsystem and absorbs the heat, cools down the dehumidification solution that flows down from the top to take away the heat in dehumidification solution and the air heat and mass exchange process, strengthen the solution dehumidification ability among the second grade dehumidification subsystem. The fresh air after two-stage dehumidification reaches an air supply state and is sent into a room.
Meanwhile, the return air enters from the secondary regenerator 23 of the secondary dehumidification subsystem and is subjected to heat and mass exchange with the dehumidification solution flowing down from the top of the secondary regenerator 23. The secondary regenerator 23 is both a solution regenerator and a condenser in the compression heat pump subsystem, part of refrigerant in the compression heat pump subsystem is cooled in a heat exchange copper pipe arranged in the secondary regenerator 23, and the dehumidification solution flowing down from the top is heated, so that the heat-mass exchange driving force of the solution and return air is increased, the solution is regenerated, and the regeneration effect is improved. The return air is heated after flowing out of the secondary regenerator 23 and continuously enters the primary regenerator 10 of the primary dehumidification subsystem to perform heat and mass exchange with the dehumidification solution flowing down from the top of the primary regenerator 10. The dehumidification solution of the primary dehumidification subsystem flows in the semi-permeable membrane of the primary regenerator 10 and is simultaneously heated and regenerated by medium-grade heat from the absorber 13 and the condenser. Meanwhile, the high-temperature return air can also heat the dehumidifying solution in the semi-permeable membrane of the primary regenerator 10, and the two heat sources jointly realize the regeneration of the solution of the primary dehumidifying subsystem.
When the two-stage dehumidification subsystem works, most of solution at the bottom of the dehumidifier is taken as internal circulation solution of the dehumidifier, and is sent to the top of the dehumidifier by the self-circulation driving part of the dehumidifier to exchange heat and mass with fresh air; the rest part of solution flows out from the bottom of the dehumidifier and enters the regenerator for solution regeneration, and most of the solution at the bottom of the regenerator is taken as the circulating solution in the regenerator, is sent to the top of the regenerator by the self-circulation driving part of the regenerator and is heated by a heat source for regeneration; the rest solution flows out of the bottom of the regenerator and is sent to a dehumidifier by a driving part.

The rich solution absorbs the refrigerant water vapor in the absorber 13 and gives off heat to heat the circulating water in the absorption heat exchanger 30. The high temperature refrigerant water vapor generated from the concentrated solution in the generator 15 enters the second condenser 11, is condensed into liquid refrigerant water and releases heat, and the released heat heats the circulating water flowing from the absorption heat exchanger 30 to the condensation heat exchanger 28. The medium-grade hot water flowing out of the condensing heat exchanger 28 enters a first-stage regeneration refrigerant channel of the first-stage regenerator 10 to heat and regenerate the solution. The liquid refrigerant water in the second condenser 11 enters the second evaporator 12 to evaporate and absorb heat to become refrigerant water vapor, and the refrigerant water vapor is absorbed by the concentrated solution in the absorber 13. And completing a circulation system of refrigerant water and lithium bromide solution.
The evaporation process in the second evaporator 12 cools the circulating water in the evaporation heat exchanger 29 to become chilled water. The chilled water firstly flows through a primary dehumidification refrigerant channel in a primary dehumidifier 7 to cool the dehumidification solution, then enters a cold water radiation tail end coil 1 to remove indoor sensible heat load, then enters an evaporation heat exchanger 29 through a refrigeration driving piece 8 and is cooled to form a complete water circulation loop.
