Chilling water host energy storage

What is chilled water thermal energy storage?

Chilled water thermal energy storage involves storing chilled water to be used to cool the equipment in the data center during key times – mostly during power outages that knock the typical cooling equipment off line. How Chilled Water TES Tanks Work 1.

What is chilled water storage (CWS)?

Chilled water storage (CWS) is one of the most popular and simple thermal energy storage forms, using insulated water tanks to store chilled water that is generated with conventional chillers.

How does a chilled water storage tank work?

When charging the tank, the warm water is taken from the top of the tank and sent to the chiller, while the chilled water is returned to the tank near the bottom. Chilled water storage tanks require a large footprint to store the large volume of water required for these systems.

Why should data centers use chilled water thermal energy storage tanks?

Chilled water thermal energy storage tanks represent a smart, efficient solution for managing the temporary cooling needs of data centers. As the demand for data processing and storage continues to rise, the incorporation of cooling solutions like TES tanks will be essential in ensuring the reliable operation of data centers worldwide.

Does a chilled water storage system provide the best economic performance?

In this study, the chilled water storage (CWS) was analyzed for use in an academic building cooling system in order to find the optimum solution that provides the best economic performance: low PB and high IRR.

Is a stratified chilled water storage tank a virtual chiller?

The stratified chilled water storage tank was modelled as a “virtual chiller” to quantify the energy consumption related to the charging/discharging. Multiple charging/discharging cycles were controlled for optimal chiller loading. The proposed control strategy was evaluated in a simulated complex central chilled water plant.
