Patent ID: 7356997

Claim:
A method for cooling the interior of a building while conserving energy during peak demand hours, comprising the steps of: chilling water during off-peak electrical demand hours by passing the water through a first conduit, said first conduit comprises a warm water line, a four-way valve, a chiller line, and a first three-way valve, so that during the off-peak electrical demand hours, water passes from a warm water storage tank to said warm water line, from said warm water line through said four-way valve to said chiller line, and through said first three-way valve to a water chiller; passing the chilled water through a second conduit from the water chiller to a cold water storage tank; releasing the chilled water from said cold water storage tank during peak electrical demand hours and passing the chilled water, via a third conduit, through a heat exchanger, wherein heat is transferred from ambient air in the building passing through a connected air duct system to the chilled water, so that the temperature of the ambient air in the building is lowered and the temperature of the chilled water is raised; and passing the water through a fourth conduit to a warm water storage tank, wherein the water is stored to be sent through the water chiller during off-peak electrical demand hours.
