Solution Overview
Problem
Conventional dehumidifiers increase the temperature of discharged air, causing user discomfort and require time for refrigeration cycle stabilization, which prolongs dehumidification time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional refrigeration cycle is used for dehumidification, then moisture can be removed from air, but the discharged air temperature increases causing user discomfort
Solution Approach 1:
The invention divides the air flow into two separate streams: a main flow that passes through the dehumidification module for moisture removal, and a secondary flow that passes through the heat exchanger for temperature control. This segmentation allows independent optimization of each stream's function, enabling moisture removal without excessive temperature increase in the discharged air.
Solution Approach 2:
The heat exchanger acts as an intermediary device that pre-cools the incoming air or recovers heat from the dehumidified air. By introducing this intermediate heat exchange step, the system can control the temperature of air entering the dehumidification module, thereby controlling the final discharged air temperature while maintaining effective moisture removal.
2Quantity of substance
If a refrigeration cycle is used for dehumidification, then moisture can be removed, but time for refrigeration cycle stabilization is required which prolongs dehumidification time
Solution Approach 1:
The invention replaces the complex refrigeration cycle (which requires stabilization time) with a membrane-based dehumidification module that operates immediately upon air flow initiation. The membrane module uses physical separation rather than phase change cycles, eliminating the need for stabilization time and enabling immediate moisture removal when the system starts.
3Quantity of substance
If air flow direction is not optimized, then moisture separation performance is reduced, but system complexity increases with optimized flow paths
Solution Approach 1:
The invention employs asymmetric flow path design where the main air flow and secondary air flow follow different trajectories through the housing. The main flow passes directly through the dehumidification module while the secondary flow passes through the heat exchanger. This asymmetric configuration optimizes moisture separation by ensuring proper flow directions without requiring complex adjustable mechanisms, achieving high performance with simple fixed geometry.

Function Achieved in This Case
Achieves constant temperature dehumidification, reduces dehumidification time, and improves moisture separation performance by using a two-way suction fan and vacuum pump to efficiently separate and condense moisture without increasing indoor space temperature.
Implementation Method 1
selectively separating moisture in the air passing through the dehumidification module without increasing the temperature of an indoor space
Implementation Method 2
moving water vapor in the air passing through the dehumidification module to the inside of the membrane by generating a pressure difference between the inside and outside of the membrane using a vacuum pump
Implementation Method 3
the separated water vapor falls in the direction of gravity, making it easy to collect water vapor and forming a compact piping connected to a vacuum pump
