Hi everyone,

I have created a customized hourly report for chillers to understand the
supply water temperature of screw chillers. It was observed that the
leaving temperature is varying from 44?F to 65?F which is quite high.

This seems very strange as the set-point cooling control is fixed and the
set point cooling temperature is 44?F under the chilled water loop. Also I
have considered the loop set point range as zero (0). As per the inputs
entered under the chilled water loop, the supply chilled water temperature
should be near around 44?F.

Can anyone guide me on this, why the supply water temperature of the
chiller is varying and how I can fix this?

Thanks in advance.
