Don't laugh at the idea of ice cubes. I wish I had the source, But I have read of american city towers using ice cubes to supplement the cooling systems during summer, because when the ice cubes get VERY large, they are tremendously efective (way more effective than normal air conditioning heat exchange units). At the end of the day, the melted ice is still cool and easy to refreeze. The total energy savings are quite substantial. Maybe if you're interested you can google it up ( =
i concur. my faculty uses such cooling system.at night when energy needs are at its lowest, the system uses up electricity to freeze the water.
during the day, the ice is used to chill water, which is then circulated throughout the building. the chilled water runs thru coils in the air ducts, which in turn chills the air.
very cost effective for large complexes, considering the cost of water over refrigerants.
if i'm not mistaken, one such system will be built in putrajaya too. i knew this when one of their consulting engineers came to our faculty to give a talk.
