When it comes to safeguarding your business’s IT backbone, Server Room Air Conditioning is not a luxury—it’s a necessity. Servers generate significant amounts of heat, and without proper cooling, performance, reliability, and even data integrity can be at risk.
Let’s explore why server room air conditioning is so important, how it works, and the benefits of having a resilient system in place...
Benefits of Server Room Air Conditioning
- Consistent performance: Servers operate best within a narrow temperature range.
- Extended equipment lifespan: Reduced thermal stress means fewer hardware failures.
- Energy efficiency: Modern systems are designed to deliver cooling with minimal power consumption.
- Reduced downtime: Stable conditions prevent costly interruptions to business operations.
What is Redundancy and Why is it Important?
Air conditioning redundancy means having backup cooling systems in place so that if one unit fails, another immediately takes over. In a server room, this is critical because IT equipment generates constant heat, and even a short cooling failure can cause overheating, downtime, or data loss.
Server room air conditioning redundancy usually defined in 1 of 2 ways:
N+1 Design: One extra unit beyond the minimum required, ensuring resilience.
2N Design: Full duplication of cooling capacity for maximum reliability. 100% back up.
A perfect example of a 2N Design 100% backup server room air conditioning system is the system Torr Engineering installed at the Immingham Combined Heat & Power Station – VPI.
Redundancy is key in mission-critical environments.
Benefits of Split System Air Conditioning
We describe in detail what the differences are between all the available types of air conditioning systems, including split systems, in our FAQ’s here.
But essentially, a split system just means 1 outdoor condensing unit running 1 indoor evaporating unit.
The main benefit of using several smaller split systems over a larger type system in a server room environment is that they are completely independent of each other – and if 1 system breaks down, you still have several others working. If you are using just 1 larger system to cool your server room and it breaks down, you lose ALL of your cooling.
Consequences of Cooling Failure
The risks of failed cooling are severe:
- Overheating servers can lead to immediate shutdowns.
- Data loss and corruption may occur if systems crash.
- Permanent hardware damage can result from prolonged exposure to high temperatures.
- Business disruption is inevitable, with downtime costing both money and reputation.
And That is the Exact Situation our Last Client Found Themselves in With Their Server Cooling System.
Our clients based in Lincoln had a server room disaster when their only air conditioning system failed, leaving them with no cooling whatsoever and rising server room temperatures.
To help prevent this type of complete failure in the future, Torr replaced the single large VRF system with a system made up of 3 x 14kW split systems. The cooling requirement for the server room was 28kW, so this new N+1 design provided a full backup unit in the event of any other unit failing. The installation was also made up of 3 completely independent split systems, so any faults would only effect 1 system, leaving the other 2 systems providing the full 28kW cooling requirement.
The large server room VRF condensing system failed and was beyond economical repair. The unit had to be dismantled and removed to make way for the new system.
Two other redundant systems that were not being used were also decanted of their refrigerant and removed at the same time to make way for the new split system condensing units.
