Ice cooling systems work

Howstuffworks "Are ice blocks better than air conditioning?"

This is a great how-to on ice air cooling. The simple version is this: Freeze many blocks of ice at night when temps are low, let evaporate and blow through existing cooling ducts. Refreeze and repeat.

Many large corporations are using this method to cut cooling costs, saving themselves, and their shareholders, millions of dollars.
