Data Center Cooling Choices: Evaporative Versus Refrigeration Systems Explained

During the recent Batavia City Council meeting on July 21, 2025, discussions centered around the cooling technologies used in data centers, highlighting the implications for local infrastructure and business operations.

The council explored two primary cooling methods prevalent in the data center industry: refrigeration-style cooling and evaporative cooling. The refrigeration method involves circulating a closed loop of chilled water to cool computers, while evaporative cooling utilizes on-site process water to achieve similar results. Each method has its advantages, with the choice often influenced by geographic conditions.

Evaporative cooling is particularly effective in dry climates, making it a popular choice in regions like Texas and parts of Southern Europe. However, its efficiency diminishes in humid environments, such as the Midwest, where high humidity levels can hinder performance. This was a significant point of discussion, as the council recognized that adopting evaporative cooling systems in Batavia could limit the area's appeal to potential data center customers.

The council's decision to favor refrigeration-style cooling reflects a strategic move to ensure that Batavia remains competitive in attracting data center businesses. By opting for a cooling method that aligns with the local climate, the city aims to enhance its infrastructure and support economic growth.

In addition to the cooling technology discussions, the meeting addressed other community concerns, including infrastructure improvements and public safety initiatives. These topics underscored the council's commitment to fostering a thriving business environment while ensuring the well-being of Batavia residents.

As Batavia continues to navigate the evolving landscape of data center operations, the council's decisions will play a crucial role in shaping the city's economic future and its ability to attract new businesses.
