Indicative location of Buffer Tanks

Part Thermal Energy Storage (TES) Discharging & Chiller Plant Utilization Tanks

Chilled Water demand is met through partial plant and partial Thermal Energy Storage (TES) Tank Discharge

Technical Standard

Buffer tanks must follow safety and insulation standards. If pressurized, it needs to meet  ASME. It should be well-insulated, pressure-tested, and support smart monitoring for open protocol like BACnet or Modbus.

ASME Boiler & Pressure Vessel Section VIII, DIV.1

Standard for pressure vessels to ensure safe design, construction, and testing of pressurized tank.

Insulation and Energy Codes

Buffer tanks must meet local building and energy efficiency codes, including minimum insulation (R-value) requirements.

Smart monitoring

Smart monitoring features available for integrations.

Performance

A buffer tank is a thermal energy storage device used in data center cooling systems to provide stable temperature and flow. Its performance is defined by its ability to store and release thermal energy effectively and reliably.

Pressure Vessel Standards

Applies if the tank is a pressurized vessel. Ensures it’s safe under pressure

Computational Fluid Dynamics

Optimization of tank designs, leads to improved uniform flow and thermal stratification.​

Thermal Performance Standards

Evaluates storage and heat loss behavior and ASHRAE Standards (USA)
