Heat Load TestingHeat Load Testing

With the increasing number of heat dense environments, such as data centres and specialist manufacturing, comes the need for HVAC systems to prove they can handle the heat load well before the equipment is installed.
Why Is Heat Load Testing Required

Heat density in data centres and other heat generating environments is on the rise globally. With this increase comes the need for precision cooling via heating, ventilation, and air conditioning (HVAC) systems.

Purpose-built facilities are designed from the outset for specific heat loads but, more often than not, existing buildings are converted, and the HVAC system is retrofitted to account for the vast heat load increase.

Whether new build or retrofit the HVAC system must be tested before the servers or other heat generating equipment in installed. That’s where heat load testing comes in.

What Is Heat Load Testing
Heat load testing does exactly as its name suggests – an artificial heat load is created to test if the HVAC system can handle it.

The last thing a CIO or facility manager wants is for highly specialised, heat sensitive equipment to be installed only to find that the HVAC system doesn’t work effectively or efficiently.

Because of this, an architect or construction consultant usually specifies in their tender documents that a heat load test must be done before sign off.

The Heat Load Testing Process

With compliance and business risk mitigation in mind, heat load testing specialists are engaged.

The maximum heat load is specified in kilowatts by the architect or construction consultant. Based on this number the heat load specialist will define how many electric fan forced heaters are required to reach the specified maximum.

Unusual room shapes or extreme heat output differences within the environment also need to be accounted for when designing the heat load test.

The heaters are strategically placed in the room and then turned on.

The heaters used in heat load testing are industrial heaters and are designed to work in high temperatures and for extended periods, so leaving them to run overnight does not pose any risks.

The heaters are also fitted with appropriate safety devices that both meet Australian safety standards and ensure plug and play usability.

We use specialist equipment to power numerous heaters at once ensuring the power drawn on circuit boards don’t create problems or blowouts.

If mains power isn’t available then we are able to provide generators to provide temporary power as part of our heat load test solution.

Once the heaters are in place we monitor and adjust them to meet the specified heat load.

The HVAC system can then be tested at varying loads, over nominated time periods regardless of the ambient condition.

Installs range anywhere from four days to three weeks.
