The Absolute: FreeCooling system is designed for cost-effective cooling of objects by controlled supply of colder outdoor air into the premises. Supports joint work with the air conditioning system, optionally with heating equipment.
Application: base stations of telecom operators, data centers, industrial premises.
Priority cooling is provided by freecooling. Cold air enters through the air intake, passes through the check valve, supply fan and air filter. Warm air is expelled through the check valve. Air conditioning (heating) is switched on only if the free cooling capacity is insufficient, as well as in cases when the operation of the free-cooling system is prohibited.
The system is controlled depending on the ambient temperature and the room temperature in accordance with the set operation logic.
Absolute: FreeCooling consists of a freecooling installation with connected climate equipment. All components of the system are controlled by a FreeCooling controller with software in accordance with programmable algorithms. The connection of external software based on the IoT platform Absolute: SmartCloud allows you to organize remote monitoring of an unlimited number of geographically distributed engineering facilities and remotely control their operation in both automatic and manual mode.
To ensure comprehensive monitoring, the system can be equipped with additional devices: tilt angle sensor, leakage sensor, etc.
