Buffer Tank. A buffer tank is a storage tank used on the cold user side of an air-conditioning system. The tank is used as storage to cover peak loads or in situations when a surge in demand exceeds the capacity of the cooling system. The system can be the secondary side of a traditional compressor-driven system or a free-cooling system, where ...
2-Pipe Versus 4-Pipe Buffer Tank Configurations
FIGURE 5. In this "2-pipe" buffer tank scenario, the flow velocity entering the buffer tank is lower than with the "4-pipe" arrangement shown in figures 1 through 3. Lower entering flow velocities helps preserve temperature stratification, and thus maintain the warmest water at the top of the tank, ready for transfer to the load.
Thermal Storage Vessel Sizing
Occasionally the energy storage capacity of a vessel will be quoted. This actually depends upon the operating conditions of the system.
