CVP: Controlled Vapor Pressure

The Airwatergreen liquid desiccant dehumidification system operates on the principle of absorption of water vapor from air.

The systems utilize a liquid absorbent known as BAS. The BAS is non-toxic, will not vaporize, is free from corrosive chlorides and is not degraded by common airborne contaminants.

The temperature and concentration of the solution – i.e. the vapor pressure – determines the ability of BAS to remove or add water vapor from the air.

The concentration of BAS can be adjusted so the conditioner delivers air at any desired relative humidity between 30% and 90%.

The illustration below shows the basic elements of the liquid desiccant system. Conditioned air can be heated/cooled and humidified/dehumidified by contacting BAS in the conditioner.

Warm Condensation – a solid desiccant technology

Using the concept of over-saturation to create condensation inside a closed environment – where the vapor has been collected.

  1. The humidity is first collected in an adsorbent (silica gel).
  2. At saturation, the adsorbent is dried by warming up the box containing the adsorbent.
  3. This generate vapor that condensates at the inside of the adsorbent box.

OneStep HVAC – the evolution from traditional sorption to modern CVP

NEXT-S is a single step solution for cooling/heating or dehumidifying/humidifying.

The Technology makes it possible to change the air condition to a chosen set point for temperature and humidity.

This is presented in the Mollier diagram where the NEXT-S takes a direct path (green arrow) to reach the chosen air condition, as compared to existing technologies taking a multistep reconditioning path (blue arrows).

The methodology is used for humidifying and heating during wintertime – and then using exactly the same installation module for dehumidification and cooling during hot summer days.
