1.5-MG Chilled Water
Storage Tank
Thermal energy storage is a process whereby electric power requirements for
cooling can be shifted from high demand to low demand periods. This is accomplished by producing
ice or chilled water during times of low power demand and storing it for use
later when it is needed. For instance, most power generating facilities
reach their peak capacity during the middle of the day. In order to meet
the demand of their customers, they must size their production facilities for
this peak production. To compensate for the cost of oversizing their
equipment, they often bill demand charges for the largest users.
Additionally, power providers are more and more going to time-of-use pricing for
power in which power is more expensive during the day than at night.
Thermal storage allows you to take advantage of the cheaper rates and thereby
reduce your energy bills.
Thermal storage takes advantage of the natural properties of water which
cause it to naturally stratify at different temperatures. By properly
designing  an inlet and outlet diffuser system, a single tank can be
used to store cold and warm water separated by a boundary layer known as a
thermocline. The diffuser must be designed to minimize
the effect of mixing so that the  density differences of the cold and warm water
will result in stratification. The octagon configuration used by The Crom
Corporation allows for the most efficient distribution of the water across the
plan area of the tank.
Prestressed Composite Tanks built by The Crom
Corporation are particularly well suited for these applications. By
insulating a prestressed composite tank, you take advantage of the low
maintenance characteristics of the tank and the efficient surface area to volume
ratio of a cylinder for the most cost effective solution to chilled water
storage.
Key Benefits
- Prestressed concrete is the ideal material for water/ice storage tank
construction.
- Tanks may be partially or completely buried without concern for
maintenance.
- Aesthetically pleasing insulation systems may be added economically.
- The free-span concrete dome can be designed to support the loads of
internal piping or ice machines.
- Interior surfaces do not require costly coatings or maintenance.
- Diffusers are designed for little or no maintenance.
