Flooded type water cooled screw chiller (MIC) MCAC-CTSM-2018-1
22
7. Water flow
Balance the chilled water flow through the evaporator and the condenser water flow through the
condenser. The flow rates must fall between the minimum and maximum values shown in the table
below. Flow rates below the minimum values shown will result in laminar flow which will reduce
efficiency, cause erratic operation of the electronic expansion valve and cause low temperature cutouts.
On the other hand, flow rates exceeding the maximum values shown can cause erosion on the heat
exchanges water connections and tubes, even piping breaking.
Variable chilled water flow through the heat exchanges while the compressor(s) are operating is not
recommended. The chiller control set points are based upon a constant flow and variable temperature.
