INTRODUCTION

Dehumidifiers are refrigerant cycle
machines combined with radiant air-
conditioning systems, from which
they draw a certain water flow rate
to increase the dehumidification
efficiency and reduce electricity
consumption.
The cooling systems employ chilled
water at temperatures between 15°C
and 20°C, which is enough to take the
rooms to the desired temperature,
but not suitable for dehumidification.
To lower the latter, you would need
water at 7°C, resulting in a reduction
in the performance of the water
chiller compared to when the water is
produced at 15-20°C.
Water-co o l e d refr i ge ra nt cycl e
dehumidifiers are used to keep the air
humidity at optimal values (55-65%)

in rooms, with the following benefits
compared to other systems:
• They employ the chilled water
available in the radiant panel
system;
• They are used to process the air
without modifying its temperature
and, therefore, without affecting
the operation of the radiant
panels and their adjustment
system.
