FCB

Free Cooling System

Free cooling is a method of using ambient external air temperatures in the natural environment to reduce the temperature of stored water. Depending on the external air temperatures and the temperature you want to achieve, chillers can typically be partially or fully offloaded for up to 90% of the year. It simply means that you can significantly reduce the energy consumption, and achieve a lower carbon footprint for your company. Various industries employ free cooling systems, from hotels and hospitals, to server farms in computer data centers and businesses that want to employ green technologies to protect the environment.

 

Free cooling provides significant opportunities to generate energy savings. It can take effect when the difference between the outside supply and return temperatures is as little as 1°C. This means that, in a 24/7 data center with a typical room temperature of 24°C, over 95% of the year can be spent with free-cooling active. 

Introduction for Free Cooling System

The FCU has been used for data centers and telecommunication companies. For data centers, indirect heat exchange air handling units provide essential water and air filtration to prevent ingress of potentially damaging contaminants and, with their substantial energy savings potential, air handling units can drastically cut energy costs compared with traditional and chilled water systems over the course of their lifetime.

Feature in details

 

1. Operational Service

Allows critical components to be maintained/replaced while system is in operation

2. Easy service access

Allows for all serviceable components to be replaced/maintained by easily accessible panels/doors

3. Service monitoring

All the monitoring devices on board the unit allow for preventive maintenance and a check of the working condition of the system while its in operation

 

MANAGEABILITY

 

1. Building management system integration

Send alarms allowing you to manage critical building infrastructure from a single system.

2. Network interface

Provides management by connecting the device directly to the network with a dedicated IP address, avoiding the need for a proxy such as a server. Management is available via Web browser or other media. Notification features inform you of problems as they occur.

3. Local area network

Creates a shared control between all the available resources for maximum energy efficiency and controlled management of the group during emergency situation.

4. Sensors

The use of temperature sensors and sequencer controls allows for cooling to be staged, ensuring a smooth transition from mechanical cooling to air free cooling.

5. Reduced fan speeds

Energy can be reduced further by setting fans to operate at less than full capacity without compromising performance at full load; A fan working at up to 80% of capacity for example will reduce energy consumption by up to 50% for the same performance.
