Types Of Data Center Cooling Techniques






To ensure that your equipment is functional, it is vital to have proper temperature control in your data center. A data center that is too hot or humid can lead to financial difficulties for your business. This guide will provide information on data center cooling solutions.

Free Cooling

The cost-effective option to make sure your data center’s temperature flow works properly is free cooling. The cooling required is minimal and will result in lower cooling costs. This technique consists of two systems: air-side or water-side economy. Air-side economy uses outdoor air to regulate equipment’s temperature.

Chilled Water System

Liquid cooling can be more effective and efficient than other cooling methods. This is because chilled water can directly target the desired area and not require cooling air to be distributed to all areas. The chilled water technique uses a chiller to connect the CRAH. The chilled water passes through coils to engulf the heat and deposit it in the chiller. When the chilled water returns to its chiller, it combines with condenser waters flowing through a cooling tower.

Pumped Refrigerant

This technique pumps chilled water through a heat exchanger and then uses a cold-pumped refrigerant (cold-pumped refrigerant) to extract the heat. Pumped Refrigerator technology allows for savings because it can transmit energy to servers. Also, it permits humidification to be greatly decreased.

Indirect Air Evaporative System

This method uses an air duct, which is connected to an indirect evaporative cooler. This method uses the outside temperature to cool the facility. This air is used in cooling the airflow inside the data center.

Data Center Organization

Optimizing your data center’s organization and placement is a cost-effective way to make sure it maintains productivity. For optimal data center temperatures, the efficient organization includes hot/cold aisle arrangement and rack placement, cable organization, and the use of blanking panels.

Hot/Cold Aisle Arrangement

Hot and cold aisles can be managed to maintain the temperature in data centers. If the hot and cold aisles are not separated, the air in the data center will experience “mixing,” which is an inefficient way to use energy. The equipment is not able to be submerged in the ideal temperature if it is air mixed. By positioning racks, the hot/cold aisle method allows lanes to be separated by hot and cold aisles.


To isolate hot and cool air from racks, you can use containment through the hot/cold aisles. HVAC units perform better when contained. The hot air should be monitored to make sure that it does not exceed its limit.

Rack Placement

Heat circulation can be reduced by placing racks in a way that minimizes heat transfer from rack hot points. The rack’s top is the hottest. If you want to achieve optimal cooling, arrange your racks so that the heavy equipment is placed on the lower racks. Higher equipment circulates air more efficiently, so a lower rack position will allow for less hot air to be dispersed at its top.

Cable Organization

Not only will your cables be easier to manage and neater, but they also won’t impede the data center’s airflow. It’s a small step toward optimizing your data center’s airflow.

Blanking Panels

If you have racks that are empty and your data center isn’t using blanking panels, heat is being emitted to your data center’s atmosphere to make room for rack space. Blanking panels can block hot air from entering your server’s airflow. This will ensure greater cooling efficiency.

Environmental Monitoring

You should also be able to manage and monitor your facility in real-time. Environment monitoring is crucial to ensure that your data center equipment is at the right temperature. Environmental sensors allow you to monitor and control the airflow, humidity levels, and temperature in your data center.
