What is thermal energy storage for Space Cool-ing?

Finally, the appen-dixes give Federal life-cycle costing procedures and results for a case study. Thermal energy storage for space cool-ing, also known as cool storage, chill storage, or cool thermal storage, is a rela-tively mature technology that continues to improve through evolutionary design advances.

What type of cooling system is used in a water aquifer?

The cooling system mainly consisted of dry cooler, ground source HX, standby conditioner and TES, in which the ground source HX was also TES for seasonal thermal energy storage. Aquifer thermal energy storage was combined with air-cooled conditioner, to provide chilled water together with air-cooled conditioner.

How do utilities support cool storage systems?

Utilities offer various forms of financial and technical support for cool storage systems. Examples include rebates spe-cific to cool storage, rebates for peak load reduction, and cost-sharing of fea-sibility studies.

Why does a data center need a cooling system?

Data center consumes a great amount of energy and accounts for an increasing proportion of global energy demand. Low efficiency of cooling systems leads to a cooling cost at about 40% of the total energy consumption of a data center. Due to specific operation conditions, high security and high cooling load is required in data center.

What is the total energy consumption of a liquid cooling data center?

The total energy consumption includes the energy consumptions of the cabinets, uninterruptible power supply (UPS), cooling system, lighting system, power transfer, and distribution system. The PUE of the liquid cooling data centers can usually be reduced to below 1.3 [6, 7].

How much energy is saved by a cooling system?

Coupled waste heat recovery and energy storage subsystems were included. Refrigeration modes were clarified to save cooling energy. Power usage effectiveness is reduced from 1.317 to 0.981. Maximum energy saving reaches 90.8 GWh/year with 1000 cabinets. Maximum net present value reaches 998 million CNY.
