BTU Calculator - Data Centers is a free iPhone application developed by Cristinel Bontas. It falls under the Utilities & Tools category and aims to assist users in choosing the right data center cooling system for their needs.

The app utilizes a simple calculation method to estimate the cooling capacity required to maintain a temperature of 24°C, with a humidity level ranging from 30 to 50 percent. It is specifically designed for regions with a climate ranging from temperate to continental.

Some of the key features of this app include the consideration of factors such as the amount of space to be cooled, the number of occupants, the orientation and R-value of windows, and the total heat output of a data center. Additionally, it allows users to instantly view the total cooling load results as they update input data.

It is important to note that while this calculator provides a rough estimate, it should only be used as a guide. Users are advised to consult a professional and qualified contractor for accurate assessments.
