CVP: Controlled Vapor Pressure
Airwatergreen's dehumidification solution, which utilizes a liquid desiccant, applies the principle of water vapor absorption from the air.
The systems utilize a food-grade, liquid-absorbing substance known as BAS. The solution is non-toxic, non-volatile, free from corrosive chlorides, and immune to degradation from common airborne pollutants.
The temperature and concentration of the solution—in other words, the vapor pressure—determine BAS's capability 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 image illustrates the fundamental elements of the liquid desiccant system. The airflow can be heated/cooled and humidified/dehumidified through exposure to BAS.
Thermal condensation – a technology utilizing a desiccant in granular form
The supersaturation concept is applied to generate condensation within a closed environment where the vapor has been collected.
- The ambient humidity is first captured in an adsorbent (silica gel).
- Upon saturation, the adsorbent is regenerated by heating the cassette containing the adsorbent material.
- This generates vapor that condenses on the interior surface of the adsorbent cassette.
Single-stage HVAC solution processing the airflow in a single process step
NEXT-S is a single-stage solution for cooling/heating or dehumidification/humidification.
The technology makes it possible to adjust the air, as represented in a Mollier diagram, to a selected setpoint for both temperature and humidity.
The method is used for humidification and heating during the winter season – and via the exact same installation module for dehumidification and cooling on warm summer days.
