CVP: Controlled Vapor Pressure
Airwatergreen dehumidification solution using a liquid desiccant uses the principle of absorption of water vapor from the air.
The systems use a food-grade, liquid-absorbing substance called BAS. The solution is non-toxic, does not vaporize, is free of corrosive chlorides and is not degraded by common airborne contaminants.
The temperature and concentration of the solution - i.e. the vapor pressure - determine the ability of BAS to add or remove water vapor from the air.
The concentration of BAS can be adjusted so that the equipment delivers air at the desired relative humidity between 30% and 90%.
The picture shows the basic elements of the liquid desiccant system. The air flow can be heated/cooled and humidified/dehumidified by exposing it to BAS.
Hot condensation - a technology that uses a granular desiccant
The concept of supersaturation is used to create condensation in a closed environment - where the vapor has accumulated.
- The humidity is first collected in an adsorbent (silica gel).
- At saturation, the adsorbent is dried by heating the box containing the adsorbent.
- This generates vapor that condenses on the inside of the box with the adsorbent.
One-step HVAC solution that processes the air stream in one process step
NEXT-S a single-step solution for cooling/heating or dehumidification/humidification.
The technology makes it possible to change the air seen in a Mollier diagram to a selected setpoint for both temperature and humidity.
The method is used for humidification and heating in winter - and with exactly the same installation module for dehumidification and cooling on hot summer days.
