What Is A Thermal Energy Storage?


Thermal energy storage is a technology that converts excess electrical energy into stored energy that can be later used for cooling applications, and a buffer tank can be used as a storage medium in a thermal energy storage system. This technology is mainly used in buildings or industrial processes that demand large amounts of energy or a form of cooling storage, such as server room air-conditioning.

Thermal energy storage helps to balance out the energy demand and supply, managing peaks in district cooling by acting as a primary chiller that produces chilled water at night, which is then stored in the buffer tank and used the following day to cool the room, eliminating the need for daytime chiller operation.

IDC Backup Cold Energy

According to different IDC design requirements, adding atmosphere or pressure cold energy storage device to satisfy 15 – 30 minutes cooling demand in case of power failure or equipment failure, and making sure the safety of core server and data. Or as a buffer device, the energy-storage equipment improves cooling machine sets with large capacity to satisfy operation stability of low load at early stage of IDC operation.

Benefits Of

Thermal Storage

  • Cost saving. Thermal energy storage helps cut down on electricity bills as it balances out energy demand, reducing electricity.
  • Reduce air conditioning loads. Lower air conditioning load plays a big factor in terms of electricity utilities – allowing half of the utility capacity to be idle most of the year.
  • Getting Green Building Certification. Buildings with thermal energy storage are identified to be green buildings, enjoying a wide range of value enhancement.
