Heat can be measured in BTUs, tons (t), and watts (W), among other units. Let us discuss this matter a little deeper. (Room square footage x 20) + (IT equipment watt usage x 3.14) + (Active people in the room x 400)īut this is only the beginning. To determine the British thermal unit (BTU) cooling size, use the following formula: If the data center has a variety of equipment, it needs to determine an acceptable temperature and humidity range for all of it. One issue to keep in mind is that some older equipment may have been built to ASHRAE cooling requirements that are no longer valid. You will need several pieces of information to calculate the data center cooling load such as: ASHRAE produced lessons that better explained the environmental and energy implications as data centers grew more aware of energy-saving strategies and efficiency. Previous versions prioritized uptime and dependability over energy costs. A4 covers PCs, storage goods, workstations, and volume servers, and offers the widest temperature and humidity range. Enterprise servers and other storage systems classified as A1 require the most stringent environmental controls. The classification A1 to A4 of IT equipment determines the suitable environment for it, which is based on the type of equipment and how it should run. Based on the equipment categorization, the current version describes the temperatures and humidity levels at which a data center can safely be run.Īccording to the most recent ASHRAE recommendations, IT equipment should be utilized with the following parameters: Thermal and humidity recommendations for data centers are developed and published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).

Here’s how to calculate the cooling load in the data center. In the end, it lowers the risk of damaged equipment. Too high or low humidity causes condensation, corrosion, and pollutants, such as dust accumulation on data center equipment.Ī correctly calibrated cooling system can prevent these problems by maintaining the optimum temperature and humidity in the data center. In the data center, it’s not only the heat that influences the cooling load calculation.

Here’s an example of the formula in action: If you follow these steps, you should have the ideal chiller size for your needs. ?T☏ = Incoming Water Temperature (☏) - Required Chill Water Temperature.Calculate Temperature Differential (?T☏).Looking for another way to find the right chiller size for your industry and application? You can generally calculate it using this formula: General Industrial Chiller Sizing Formula
