Hi,
I am working on a pharmaceutical projects involving centrifugal chillers having following data:
1. Chiller capacity - 550TR x 2 Nos.
2. Chilled water inlet / out - 5°C / 11°C
3. York Model: YKCECFQ75CMF
4. Refrigerant: R-134a
Wanted to use variable pumping across chiller evaporator.
Any guidance as to which one is the preferred option Centrifugal with VSD or Centrifugal with star delta starter with reference to variable pumping.
Thanks
Vijay Kumar
