System Relies on Ice to Chill Buildings

By COLLEEN LONG
Associated Press Writer
NEW YORK (AP) -- As the summer swelters on, skyscrapers and apartments around the city will be cranking up the air conditioning and pushing the city's power grid to the limit.

But some office towers and buildings have found a way to stay cool while keeping the AC to a minimum - by using an energy-saving system that relies on blocks of ice to pump chilly air through buildings.

The systems save companies money and reduce strain on the electrical grid in New York, where the city consumes more power on hot summer days than the entire nation of Chile.

I've seen this idea in various forms before. As in freezers that cool things down a few extra degrees at night so they don't have to use electricity during the day when it's expensive. This idea though strikes me as perfect though and could potentially be used all across the country in the summer. Imagine air conditioning and refrigerators that freeze up water at night when the coal powered generators are just idiling. They want to give away the electricity at night because they don't want to turn off the generators. Well, until PV power makes daytime power cheaper.
