Modular ice storage for uninterruptible chilled water
A backup cooling storage system comprising at least one cooling and storage unit configured to cool a liquid supply using a quantity of cooled material when a main chiller of the liquid supply is not operational, and at least one chilling element configured to generate the quantity of cooled material for the at least one cooling and storage unit when the main chiller of the liquid supply is operational. Additional embodiments and methods are further disclosed.
1. A method of supplying emergency cooling to a cooling system of the type having at least one cooling unit, a main chiller separate from the at least one cooling unit, and at least one backup cooling unit, the method comprising acts of:
A) providing continuous cooling of the at least one cooling unit by the main chiller when the main chiller is operational;
B) maintaining a quantity of stored cooled material using a liquid supply from the main chiller when the main chiller is operational; and
C) cooling the liquid supply using the quantity of stored cooled material when the main chiller is not operational with the at least one backup cooling unit, the at least one backup cooling unit including at least one chiller configured to further cool at least a portion of the liquid supply to generate and maintain the quantity of cooled material when the main chilling unit is operational, the at least one chiller including at least one thermoelectric chiller.
2. The method of claim 1 , wherein the liquid supply includes at least one of a composition comprising water and a composition comprising glycol.
3. The method of claim 1 , wherein the act B includes freezing at least a first portion of the quantity of cooled material, and subsequently cooling the quantity of cooled material such that the first portion remains in a frozen state.
4. The method of claim 3 , wherein the frozen first portion includes ice and an unfrozen second portion of the quantity of cooled material includes water.
5. The method of claim 1 , wherein the act B includes maintaining the quantity of cooled material in a cooled material storage unit housed in a standard rack.
6. The method of claim 5 , wherein the act B includes monitoring at least one parameter of the quantity of stored cooled material.
7. The method of claim 6 , wherein monitoring at least one parameter of the quantity of stored cooled material includes monitoring a pressure exerted to release at least one bubble into the quantity of stored cooled material.
8. The method of claim 1 , wherein the act B includes cooling a portion of the liquid supply and directing the portion of the liquid supply through the cooled material storage unit such that heat transfers between the quantity of cooled material and the liquid supply.
9. The method of claim 8 , wherein the act B includes thermoelectrically cooling the portion of the liquid supply.
10. The method of claim 1 , wherein the act C includes directing a portion of the liquid supply through the cooled material storage unit such that heat transfers between the quantity of cooled material and the liquid supply.
11. The method of claim 1 , further comprising an act of D) monitoring the liquid supply to determine if the main chiller is operational.
12. The method of claim 11 , wherein the act D include monitoring at least one of a temperature of the liquid supply and a pressure of the liquid supply.
13. The method of claim 1 , further comprising an act of D) providing the liquid supply to at least one piece of cooling equipment.
