Abstract
Abstract Installation for storing continuously generated cold and for the intermittent release of at least a portion of the stored cold, with a storage container for a mixture of cold water and ice, by a cooling device for delivering ice continuously to the storage container, and with means for removing cold water intermittently from the storage container and for cycling it to an apparatus to be cooled and then for recycling it back to the storage container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
An installation for storing continuously generated cold and for the intermittent release of at least a portion of the stored cold, comprising (a) a storage container for a mixture of cold water and ice, (b) an evaporator-crystallizer containing cold water and a liquid cooling medium insoluble in the water, the cooling medium in contact with the water forming floating ice crystals during evaporation, (c) conduit means for continuously delivering the ice crystals from the evaporator-crystallizer to the storage container to constitute the ice therein, (d) circulating means for removing cold water from the storage container intermittently, cycling the cold water to an apparatus to be cooled, and then recycling the water from the apparatus back to the storage container, and (e) a device for thickening the ice-water mixture in the storage container.
Claim 2
Dependent Claim
132 words
An installation for storing continuously generated cold and for the intermittent release of at least a portion of the stored cold, comprising (a) a storage container for a mixture of cold water and ice, (b) an evaporator-crystallizer containing cold water and a liquid cooling medium insoluble in the water, the cooling medium in contact with the water forming floating ice crystals during evaporation, (c) conduit means for continuously delivering the ice crystals from the evaporator-crystallizer to the storage container to constitute the ice therein, (d) circulating means for removing cold water from the storage container intermittently, cycling the cold water to an apparatus to be cooled, and then recycling the water from the apparatus back to the storage container, and (e) a device for thickening the ice-water mixture in the storage container.
Claim 3
Dependent Claim
13 words
Installation according to claim 1 wherein the thickening device is an ultrasonic generator.
Claim 4
Dependent Claim
16 words
Installation according to claim 1 characterized in that the cold water consists of a salt brine.
Claim 5
Dependent Claim
23 words
Installation according to claim 1 or 3, characterized by an oil filter, in the conduit means between the evaporator-crystallizer and the storage container.
