System design and function
3.1 Main function
The DesiCool
™
air treatment system is a highly efficient energy recovery ventilation system. It uses low
cost or surplus heat to create a more comfortable indoor climate.
The DesiCool combines Munters advanced desiccant dehumidification technology with evaporative
cooling.
In summer the unit keeps the relative humidity in the room lower than a set summer maximum value, and
also controls the supply temperature to the set value.
In winter the unit keeps the supply temperature at the set value by recovering heat from the exhaust air, while
at the same time controlling the room humidity not to be lower than a minimum set value.

* Individual systems are built to specification, and can be different from this example.
There are several possible operation modes for the DesiCool system. Depending on the outside
temperature and humidity, and on the supply setpoints, the controller will activate the components as
needed.
