General information and technical advice on air conditioning and cooling for server rooms and datacentres.

The Energy Efficiency Benefits of Cold and Hot Aisle Containment

Hot and Cold Ailse Containment

As datacentres look to increase their energy efficiency and provide predictable cooling to their high-density racks, they are faced the choice of whether to adopt hot-aisle or cold-aisle containment. Aisle containment can offer benefits to both existing and new build datacentres and can help to remove ‘hot-spots’ and deliver uniform air temperatures to server inlets. […]

The Benefits of Liquid Cooling Solutions Over Air Conditioning Systems

Liquid Cooled Server Racks

The datacentre industry is under immense pressure to reduce its energy usage and achieve a smaller carbon footprint. One of the biggest users of non-compute energy are the cooling solutions used within hyperscale down to medium and small-sized datacentres. The traditional air-based cooling systems have always been the ‘go-to’ solution for datacentres and server rooms […]

Liquid-based Critical Cooling Systems For Data Centres

Critical Liquid Cooling Systems

The world is not getting any cooler and in the data centre industry critical cooling is becoming one of the prime areas for energy saving. Unlike the uninterruptible power supplies used within a critical power path, which are already approaching their maximum available energy efficiency (>97% in on-line mode) critical cooling has a long way […]

How To Cool Server Racks and Datacentre Cabinets

Server Rack Cooling Thermal Hot Spots

Heat is a form of ‘waste’ energy that results from the way the CPUs (central processing units) within a typical IT server work. In a server room or datacentre environment, managing ‘heat’ and keeping server racks cool is as critical an issue as ensuring the servers are protected from mains power supply failures. Excessive heat […]

Data Centre Cooling Solutions For Cloud To The Edge Sites

Liquid Immersed Data Centre Cooling Solutions

The range of cooling solutions available for server room and datacentre operators continues to evolve and can be split into two types: active cooling (forced convection) and passive cooling (natural connection). Innovation is driven by how to affect the most energy efficient and environmentally friendly cooling systems as the actual power demands for IT servers […]

The Rising Tide of Liquid Cooling Solutions for Datacentres

Liquid Immersion Cooling Solutions

Traditional air conditioners use a refrigerant gas and this type of closed-loop air-based cooling system is perfectly adequate for most for server rooms and small datacentres. However, as server rack power densities continue to increase due to machine learning applications, larger datacentres and hyperscale operators are turning to liquid cooling. Most datacentre operators don’t want […]

Cool Lessons From The Summer Heatwave

UK Temperature Projections

There is a very good chance that we will always remember the UK summer of 2018. Week-long heatwaves and an average temperature of 15.8˚C saw this summer narrowly beat the previous record temperature levels of 1976. The summer months of June and July were also notably dry, although August seemed to return to more average […]

How to Manage Sudden Server Room Temperature Rises

Server Room Thermal Imaging

With weather patterns in the UK forecast to become more erratic we are seeing a greater focus being placed on how to design a server room to ensure it is adequately cooled. This summer saw a large rise in demand for emergency air conditioning and cooling units as some server rooms struggled to maintain a […]

How to Calculate Server Room Air Conditioner Sizes

Calculating Air Conditioner Sizes

With the UK experiencing one of the hottest summers since 1976 many server room air conditioners and datacentre cooling systems are facing extreme workloads. The issue is not the ambient temperature itself but the length of time that the higher than average temperatures have been around. For future upgrades and new system installations it may […]

How to Cool Your Server Room and Reduce Your Energy Costs

Server Rack Cooling Configuration

Whether your organisation runs a small server closest or large server room or onsite datacentre, ambient and temperature control is critically important to prevent system downtime. The electronics and microprocessors within a server or computer generate heat energy which must be managed in a confined space such as a server rack cabinet, server room and […]
