Data Centre Cooling Air Conditioning Installation
Traditionally, there are two ways of cooling a data centre: air-based cooling and liquid-based cooling.
Data Centre Cooling Air Conditioning Installation is designed and installed by Power Continuity Systems Engineers.
Air-Based Data Centre Cooling Installation
The goal of a hot aisle/cold aisle configuration is to conserve energy and lower cooling costs by managing air flow.
In its simplest form, hot aisle/cold aisle data centre design involves lining up server racks in alternating rows with cold air intakes facing one way and hot air exhausts facing the other. Power Continuity Data Centre Installation experience is at your finger tips.
The most common method is air-based cooling, called ‘cold aisle/hot aisle’.
Essentially, separating cold air from the hot air.
Achieved by facing the cold sides away from the hot sides of each cabinet.
Separation creates a sort of convection system where the cabinets cool themselves.
But this does not always work.
Then data centre managers have to pump a larger amounts of cold air into the rooms.
This older, inefficient method has limitations, which is why many data centers are moving towards new innovations.
CRAC Unit Data Centre Cooling
A similar process is called ‘cold or hot air containment’.
CRAC focuses on improving the older cold aisle/hot aisle method by physically isolating and containing the servers>
By doing so, the hot and cold air does not mix.
Driving the air directly from the CRAC unit helps achieve this.
This method works fairly well, but it does have the issue of hot spots.
Heat Extraction Data Centre Cooling Installation
The last method in the territory of air-based cooling is in-rack heat extraction.
This method tries to achieve the same end goal of removing hot air, by having compressors and chillers built into the rack itself. According to Schneider Electric, both Hot Aisle Containment (HACS) and Cold Aisle Containment (CACS) can provide savings.
Hot aisle containment can provide 40% more savings than the Cold Aisle Containment.
CACS traps the cold air within the system letting the rest of the data center become a hot-air return.
While the HACS traps hot air and lets it leave through an exhaust system.
Liquid-Based Data Centre Cooling Installation
Water-cooled racks and servers are the first methods in liquid-based cooling.
This means, water cools the hot side of the cabinet, bringing the temperature down. Because water conducts electricity, the water never touches the actual components.
The water contained in basins, flow through pipes via cooling tower pumps.
That allows the water cooling to run alongside the server behind a barrier.
Cooler water helps bring down the temperature of the components inside.
On on hand, this method works well, on the other hand, the risk of leaks scares many data centre managers from implementation.
Liquid immersion cooling
Another option is the liquid-based cooling method known as liquid immersion cooling.
In this method, liquid coolant flows across the hot components of a server cooling it down. Fully emerging the servers into the fluid.
Performed by using a dielectric fluid.
This type of fluid does not conduct electricity but can damage components if not used properly
