Every summer we have to shut down some equipment due to a combination of outside temperature and high load. The air conditioners just can't keep up. As we cycle in new equipment and cycle out old, it would be nice to know if we are making our cooling problem better or worse. Even better, I'd like to be able to calculate a rough estimate of the amount of cooling we'll need to support our equipment at high load.
Is there any rule of thumb or calculation to determine how much cooling capacity will be required?
