The purpose of the Detla T 20 ton water cooled chiller is to remove heat from a process and transfer it to a separate cooling entity such as a cooling tower.
For large capacity industrial applications in which heat generated by air cooled chillers creates a problem, water cooled chillers are generally used in conjunction with a cooling tower.
Mineral deposits buildup in the heat transfer circuit can degrade heat transfer and reduce system efficiency, so water cooled chillers typically require condenser water treatment to eliminate any buildup.
Whether you need a water cooled chiller for industrial processing or another application,
A chiller equipped with a fixed speed compressor controls the temperature of the water traditionally with simple on/off of the compressor. This means that when the compressor runs, it runs at the designed load regardless of the process needs. A more advanced option is a hot gas bypass which technically keeps the chiller running but bypasses the hot gas if no cooling load is needed. This avoids the on/off of the compressor but results in a waste of energy since no cooling is required from the process.
The Delta T Systems industrial chiller with the variable speed compressor operates effectively between 10% and 100% of the capacity which means a 10 ton chiller can operate efficiently as a 1 ton as well as up to a 10ton chiller.
The Air Conditioning, Heating, and Refrigeration Institute (AHRI) conducted several studies to identify the true amount of time a chiller runs at full vs. partial load. The outcome is an integrated part load value (IPLV). The national average cost for electricity is $0.14/kw-hr. If you assume a 2 shift operation, 5 days a week for one year, the energy savings for a 10 ton chiller are $4,690 or 58% less than a chiller with a fixed speed compressor. These energy cost savings can pay for a chiller in less than 3 years.
These conservatively calculated energy savings can be much higher because most chillers are selected based on the peak usage time of the year which means the chiller is oversized for the average usage.
