Solution Overview
Problem
Humidity control apparatuses using adsorbents face challenges in maintaining optimal humidity control capabilities in both dehumidification and humidification operations due to differing saturation times, leading to inadequate performance in one mode of operation.
Innovation Solution
The apparatus alternates between first and second operations at different intervals for dehumidification and humidification, with shorter intervals for dehumidification to ensure the adsorption unit is not overly saturated, allowing for effective moisture recovery and release in both operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single switching interval is used for both operations, then device complexity is reduced, but humidity control capability deteriorates in one of the operations
Solution Approach 1:
The control section implements dynamic switching interval adjustment based on operational mode detection. This adds minimal complexity to the control logic while significantly improving humidity control capability in both dehumidification and humidification operations by preventing the performance degradation that would occur with a fixed switching interval.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures that the humidity control apparatus can adequately perform in both dehumidification and humidification operations by adjusting switching intervals based on the saturation rate, thereby maintaining consistent humidity control capabilities.
Implementation Method 1
the adsorption heat exchanger serving as the evaporator, moisture in the air is adsorbed by the adsorbent
Implementation Method 2
the moisture is desorbed from the adsorbent, and is given to the air

AI summary
A humidity control apparatus (10) alternately performs first and second operations at predetermined switching intervals. In the first operation, a first adsorption heat exchanger (51) serves as a condenser, and a second adsorption heat exchanger (52) serves as an evaporator, thereby humidifying second air by the first adsorption heat exchanger (51), and dehumidifying first air by the second adsorption heat exchanger (52). In the second operation, the second adsorption heat exchanger (52) serves as the condenser, and the first adsorption heat exchanger (51) serves as the evaporator, thereby humidifying the second air by the second adsorption heat exchanger (52), and dehumidifying the first air by the first adsorption heat exchanger (51). The switching intervals between the first and second operations are shorter in dehumidification operation of supplying the dehumidified first air to the inside of a room than in humidification operation of supplying the humidified second air to the inside of the room.
