A free-cooling system combines the installation of temperature and humidity sensors with ventilation and air conditioning systems to improve the control of your telecommunications stations, also known as BTS (Building Technology Systems).
The HVAC system can be connected to the line-EDS energy manager, which uses the programmed setpoints to compare indoor and outdoor temperatures to automatically connect the ventilation systems, using external thermal inertia to cool your centre. These setpoints also take into account outdoor humidity, and avoid connecting and activating the HVAC system when the humidity is high in order to avoid damaging the electronic equipment installed, thus improving the energy efficiency of your installation.
