Apparatus for storing cooling capacity

Claim 2

Apparatus for storing the cooling capacity of a chilled liquid to provide cooled liquid to a building having heat exchange means therein, comprising the combination of a cooling tower for providing liquid at a temperature related to the dry and wet bulb temperatures of the ambient air, a chiller including a condenser and chiller conduit means for transporting liquid between said cooling tower and said condenser to cool the latter, building conduit means for transporting liquid between said cooling tower and said building heat exchange means to cool said building, a storage tank containing packages of eutectoid salt compositions and tank conduit means for transporting liquid between said tank and said cooling tower, and valve means in said tank conduit means and said chiller conduit means for alternatively directing liquid between said cooling tower and the condenser of said chiller to cool said conderser, and between said cooling tower and said tank to store coolness in said eutectoid salt packages.

Claim 3

Apparatus as claimed in claim 1, in which said packaged salt compositions have differing freezing-melting points.

Claim 4

Apparatus as claimed in claim 2, in which said packaged salt compositions having relativley high freezing-melting points are positioned at a higher location within said tank than packaged salt compositions having relatively low freezing-melting points.

Claim 5

Apparatus as claimed in claim 1, further including a second storage tank containing packages of eutectoid salt compositions in series with said one storage tank, said packaged salt compositions in said second tank having a different freezing-melting point from said compositions in said one tank.

Claim 6

Apparatus as claimed in claim 4, in which said one tank precedes said second tank in the flow of liquid from said cooling tower to said composition-containing tanks.

Claim 7

Apparatus as claimed in claim 4, in which liquid from said cooling tower is alternatively directed to said one or said second tank.

Claim 8

Apparatus as claimed in claim 5, in which the freezing-melting point of said compositions in said one tank is lower than the freezing-melting point of said compositions in said second tank.

Claim 9

Apparatus as claimed in claim 5, in which said valve means functions to direct water from said cooling tower to said storage tank to said chiller to said building.

Claim 10

Apparatus as claimed in claim 8, in which said valve means thereafter functions to direct said liquid back to said cooling tower from said building.

Claim 11

Apparatus as claimed in claim 8, in which said valve means thereafter functions to direct said liquid back to said chiller.

Claim 12

Apparatus as claimed in claim 8, in which said valve means thereafter functions to direct liquid back to said storage tank.

Claim 13

Apparatus for storing the cooling capacity of a chilled liquid to provide cooled liquid to a building having heat exchange means therein, comprising the combination of a cooling tower for providing liquid at a temperature related to the dry and wet bulb temperatures of the ambient air, a chiller including a condenser and chiller conduit means for transporting liquid between said cooling tower and said condenser to cool the latter, building conduit means for transporting liquid between said cooling tower and said building heat exchange means to cool said building, a storage tank containing packages of eutectoid salt compositions and tank conduit means for transporting liquid between said tank and said cooling tower, and valve means in said tank conduit means and said building conduit means for alternatively directing liquid between said cooling tower and said building, and between said cooling tower and said tank.

Claim 14

Apparatus for storing the cooling capacity of a chilled liquid to provide cooled liquid to a building having heat exchange means therein, comprising the combination of a cooling tower for providing liquid at a temperature related to the dry and wet bulb temperatures of the ambient air, a chiller including a condenser and chiller conduit means for transporting liquid between said cooling tower and said condenser to cool the latter, building conduit means for transporting liquid between said cooling tower and said building heat exchange means to cool said building, a storage tank containing packages of eutectoid salt compositions and tank conduit means for transporting liquid between said tank and said cooling tower, and valve means in said tank conduit means and said building conduit means for alternatively directing liquid between said cooling tower and said building, and between said cooling tower and said tank.

Claim 15

Apparatus as claimed in claim 12 in which said liquid is water.

Claim 16

Apparatus as claimed in claim 1, in which said liquid is water.

Claim 17

Apparatus as claimed in claim 1, in which said liquid is water.

Claim 18

Apparatus for storing the cooling capacity of a chilled liquid to provide cooled liquid to a building having heat exchange means therein, comprising the combination of a cooling tower for providing liquid at a temperature related to the dry and wet bulb temperatures of the ambient air, a chiller including a condenser and chiller conduit means for transporting liquid between said cooling tower and said condenser to cool the latter, building conduit means for transporting liquid between said cooling tower and said building heat exchange means to cool said building, a storage tank containing packages of eutectoid salt compositions and tank conduit means for transporting liquid between said tank and said cooling tower, valve means in said tank conduit means and said chiller conduit means for alternatively directing liquid between said cooling tower and the condenser of said chiller to cool said condenser, and between said cooling tower and said tank to store coolness in said eutectoid salt packages, and valve means in said building conduit means for alternatively directing liquid from said cooling tower to said building.

Claim 19

Apparatus for storing the cooling capacity of a chilled liquid to provide cooled liquid to a building having heat exchange means therein, comprising the combination of a cooling tower for providing liquid at a temperature related to the dry and wet bulb temperatures of the ambient air, a chiller including a condenser and chiller conduit means for transporting liquid between said cooling tower and said condenser to cool the latter, building conduit means for transporting liquid between said cooling tower and said building heat exchange means to cool said building, a storage tank containing packages of eutectoid salt compositions and tank conduit means for transporting liquid between said tank and said cooling tower, valve means in said tank conduit means and said chiller conduit means for alternatively directing liquid between said cooling tower and the condenser of said chiller to cool said condenser, and between said cooling tower and said tank to store coolness in said eutectoid salt packages, and valve means in said building conduit means for alternatively directing liquid from said cooling tower to said building.
