Buffer Tank In Chilled Water System

Subtract that number from the chiller manufacturers recommended system capacity.

Buffer tank in chilled water system.

Typical hvac chiller systems are between 3 to 6 gallons per ton. 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. 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. Available for chilled water and hot water applications.

Chilled water buffer tanks cbt and hot water buffer tanks hbt.

Chilled water buffer tanks cbt are designed for chilled water systems with insufficient water volume capacity in relation to the chiller capacity. If a 100 ton chiller requires 1000 gallons of system capacity for high accuracy control and the total piping system totals only 600 gallons a 400 gallon buffer tank would be required.

Relatively low water volume systems require additional buffer capacity for the system to eliminate problems such as excessive chiller cycling poor temperature control and erratic system. W essels company manufactures two styles of buffer tanks. Chiller manufacturer s recommended system volume per ton v r check with chiller manufacturer for specific requirements. While 6 to 10 gallons are used for applications in which temperature accuracy is critical.
