They also reduce the return water s rate of change. When two chillers are used this is a good applica tion for piping chillers in series rather than in parallel.

Chilled water thermal energy storage tank overview. Chilled water buffer tanks cbt are designed for chilled water systems with insufficient water volume capacity in relation to the chiller capacity. The insufficiently sized systems do not have enough buffer capacity for the chilled water causing poor temperature control erratic system operation and excessive compressor cycling. Midity conditions not the chilled water temperature.

The insulated chilled water buffer tanks address this problem by adding volume to your water system s buffer. These tanks increase the capacity of a closed loop chilled water system and stabilize the return water temperature. Cemline chilled water buffer tanks cwb are designed to be used with chillers which do not have water volumes of sufficient size in relation to the chiller.
