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

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 […]

The Replacement of Server Room Air Conditioners Refrigerants

R22 Refrigerant Timescales

From 2015, it became illegal to use Hydrochlorofluorocarbons (HCFCs), including the ozone-depleting refrigerant gas R22, in refrigeration, heat pump and air conditioning (AC) systems. R22 was commonly used in cooling systems pre-dating 2004 and its ban has had a major effect on air-conditioning costs. R22 Refrigerant History R22 is a hydrochlorofluorocarbon (HCFC) and greenhouse gas […]

The Future of Internet of Things Connected HVAC Systems

Internet of Things Enabled Air Conditioners

The statement that our world is becoming more inter-connected is an understatement when you consider ‘The Internet of Things’ (IoT). In the world of HVAC and cooling systems it is easy to see that air conditioning systems are becoming more intelligent with a greater range of remote communications options which should lead to improvements in […]
