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. The insufficiently sized systems do not
have enough buffer capacity for the chilled water causing poor
temperature control, erratic system operation and excessive compressor
CWB solves this problem by adding volume to buffer the system. The
CWB reduces the rate of change of the return water.
are designed to be useful in systems with a minimum water volume.
The minimum water volume is based upon the chiller manufacturer's
requirements, 3 to 6 gallons per ton for typical air conditioning and when the temperature
accuracy is critical 6 to 10 gallons per ton. When chiller systems are properly sized, the
chiller compressor will not short cycle. Without the proper amount
of system water, the source temperature will be reached quickly and
the compressor will shut off. Many chiller compressors can only start
3 times per hour. If the compressor is off and there is a demand for
chilled water, the demand can not be met because the compressor cannot
turn back on. This causes very unsatisfied people within the building
who cannot have the required cooling. Insufficiently sized system
problems can cause excessive compressor cycling, poor temperature
control and erratic system operations.
