Free Cooling System

Standard indicators of free cooling system:

  • Reduce consumption and buy the best air conditioners in telecommunication
  • systems System performance at 24 ° C (Delta T: 2.5)
  • Cooling capacity: 3200 kW, 10 times HRV cooling capacity
  • Use a 48V DC direct fan
  • Power consumption control: In Outdoor, Indoor systems, even in low-capacity and high-regulation centers set up by large companies such as Siemens and ….
  • Very low maintenance cost (use of a DC fan without the need for an inverter, etc.)

Device power consumption:

One of the important issues in the operation of free cooling systems is the discussion of their power consumption. The reasons for the reduction of energy consumption of this system compared to similar examples can be mentioned as follows:
Use 48 VDC power supply to start the system
Use one DC fan instead of two AC fans
Ability to control the cooling rate by the intelligent system controller
Keeping the site isolated, which prevents hot air from entering and cool air from leaving, and allows less use of air conditioners
Existence of a back up set point work model when disconnecting the main power supply and using the site batter
The use of inverter compressors with energy consumption rating of A+ and centrifugal fans with remote control capability and design of air conditioning control system, reduces energy consumption by up to 70%.
Low noise: The fans and compressor used are brush-less, which reduces the noise created in the environment during the operation of the device.
Corrosion protection: Use of sheet metal protected with powder paint of corrosion and corrosion resistant furnaces, usable in wet areas or harsh environmental conditions.
Easy maintenance: Suitable design for easy installation, commissioning and repair.
Monitoring: Ability to connect to a computer via RS485 input as well as the ability to view and control parameters via a screen on the device and support the MODBUS protocol to communicate with other servers.
High security and difficulty of device theft: due to special appearance structure and dedicated power supply.
