FC Grid system
Pubblicato il 18/01/2023
The Free-cooler system has the characteristic of guaranteeing continuous air changes with the primary objective of transferring the heat generated by the equipment to the external environment (for dissipation).
Solution designed to allow high ENERGY SAVING also in site where air conditioning units without free cooling system were previously installed.
AIR EXTRACTION SYSTEM
- Group ventilation system (fan, plate, grid)
- Electrical panel “Command and Control” consists of general disconnecting switch breaker, PLC and maximum temperature thermostat
- Air inlet grid with insect protection
- Dusty filter/s
- Plenum external
- Overpressure damper
- Differential air pressure switch
The system is controlled by the PLC of the air conditioner which has the task of managing the operating cycle and detecting any alarm conditions. This system when coupled with an Ethra Tech air conditionercan be managed by the same air conditioner controller, without need for a dedicated PLC.
Fan speed is adjusted with “PROPORTIONAL” (0-10V) signal. By adopting the regulation “PROPORTIONAL”, are avoided thermal shock conditions when the outside temperature is very low. This system can also be identified as an emergency system to cool the room as it is provided an electromechanical controller (thermostat) that allows to feed the fan in an independently and separately when the detected temperature exceeds the predetermined values.
