Adiabatic cooling: of course!
Adiabatic cooling, or evaporative cooling, is an effective way of cooling. The air inside is cooled by evaporating water. It is a more energy-efficient and sustainable alternative to regular air conditioning. Depending on the airflow, this way of cooling is up to 80% more efficient and has been used for centuries. In this blog, we explain adiabatic cooling and why it is also an effective way of cooling at home.
How does an adiabatic air cooler work?
The adiabatic air cooler is easy to connect to the channel of each MVHR system. As a result, the warm air from the room does not enter the WTW system directly, but first passes through the cooler. In this cooler there is a so-called matrix; a construction that is continuously humidified. This moisture evaporates and cools the warm air. The cool air is then stored in the heat exchanger of the MVHR unit and makes this basically a cold exchanger. The heat exchanger system continuously supplies clean outside air. This air flows past the heat exchanger and thus the warm air from outside is cooled. Finally, the MVHR unit blows the cool air into the room. Because we work according to the evaporation principle, the highest efficiency is achieved when the relative humidity in the house is low.

Direct or indirect adiabatic cooling?
The above process is also known as indirect adiabatic cooling. The moisture is removed and thus not blown into the room. This type of cooling is therefore very suitable for rooms in which humidity must remain constant.
If varying humidity is not a problem, direct adiabatic cooling can also be chosen. This method is less complicated because the moisture does not need to be drained. Is this option preferred? Then the chiller should be mounted on the supply air duct from the WTW unit to the room.
What if cooling is not necessary?
A heat recovery system has the advantage of automatically heating the supply air. This provides considerable efficiency and thus energy savings. This is also the reason why many people choose such a system.
All new MVHR systems are equipped with a bypass as standard. This valve helps cool your home during summer nights. It blocks access to the heat exchanger. When the bypass is open on summer nights, cooler outside air flows in and cools the house. The warm air being exhausted will not move over the bypass and be discharged directly to the outside. In case an adiabatic air cooler is installed anyway, it will automatically switch off when the desired room temperature, as set on the control panel, is reached.
Advantages of adiabatic cooling
- Up to 80% more effective than conventional air conditioning
- Easy to connect to any heat recovery system
- Ventilation, heating and cooling in one
- The warmer and drier the outside air, the higher the efficiency
- Environmentally friendly (natural cooling)
- Century-old, proven cooling technology
