Name one type of cooling method commonly used in data centres.

In-row cooling is a commonly used method in data centres because it effectively addresses the cooling demands of high-density equipment. This method involves placing cooling units directly within the server racks or rows of servers, allowing for a more localized cooling approach. By positioning the cooling systems close to the heat sources, in-row cooling minimizes air mixing and reduces the distance that cooled air must travel, leading to improved energy efficiency and more effective temperature management.

This method also enhances reliability and helps maintain optimal operating temperatures for equipment, which is critical for reducing the risk of overheating and ensuring the longevity of the hardware within the data centre. Additionally, in-row cooling can be paired with other cooling techniques to create a more comprehensive thermal management strategy, adapting to the specific needs of the facility.

While evaporative cooling, geothermal cooling, and solar cooling are also valid cooling methods, they serve different applications and may not offer the same level of precision and efficiency as in-row cooling when it comes to managing the heat generated by dense server environments.
