  • Patent number: 7356997
    Abstract: The chilled water storage for milk cooling process encompasses methods for chilling liquids during off peak hours for later consumption, including a method for cooling the interior of a building while conserving energy during peak demand hours, in which water is chilled in a water chiller during the off-peak electrical demand hours, then stored in an insulated tank until peak electrical demand hours. The stored cold water is then pumped through a heat exchanger connected to the ventilation system in the building to cool the air in the building. The water then passes into a second storage tank, where it is held until off-peak hours. A plurality of multi-directional valves automatically control the water flow through the system.

  • Patent number: 7222492
    Abstract: A process for cooling liquids wherein a coolant is cooled in a chiller during off-peak electrical demand periods, then directed to a first insulated storage vessel where it is stored until off-peak electrical demand periods have ended. During peak electrical demand periods, the coolant flows from the first insulated storage vessel to a flat plate heat exchanger, where a flow of liquid to be cooled, entering through a second conduit, is cooled. The cooled liquid exiting the heat exchanger is directed to a second insulated storage vessel where little or no further cooling of the liquid will be necessary during peak electrical demand periods.
