Abstract
An air moisture control system for a computer system includes a housing with an air passage and an air moisture control element with an adsorption material, which is exposed in the air passage so as to enable fluid communication towards and from the air moisture control element. The element is designed such that the adsorption material is adapted, in operation, to adsorb moisture from a first air flow flowing into the air passage, having a first temperature and a first relative humidity, and desorb moisture to a second air flow, said air flow having a second temperature at least 5° C. higher than the first temperature and a second humidity at least 3% lower than the first relative humidity.
Claims7
A method of moisture control for a computer system comprising an air moisture control system, the air moisture control system in turn comprising a housing that defines an air passage;
- at least one fan for causing an air flow through the air passage;
- and an air moisture control element with an adsorption material, the air moisture control element exposed in the air passage so as to enable fluid communication toward and from the air moisture control element, the method comprising:
- flowing a first air flow in the air passage by operation of the at least one fan, said first air flow having a first temperature and a first relative humidity, for the adsorption material to adsorb moisture from the first air flow;
- changing operation of the at least one fan to switch over from flowing the first air flow in the air passage to flowing a second air flow in the air passage;
- and
- flowing the second air flow in the air passage by operation of the at least one fan, said air flow having a second temperature and a second relative humidity, the second temperature being at least 5° C. higher than the first temperature and the second relative humidity being at least 3% lower than the first relative humidity, for the adsorption material to desorb moisture to the second air flow.
