Maintenance Considerations
This period discusses general maintenance requirements of helical-rotary water
chillers. Although some of the information applies specifically to the design
presented in this clinic, requirements for other helical-rotary chiller designs are
also included.
Once a helical-rotary chiller is installed and put into operation, it usually
continues to function without a full-time attendant. In many cases, the machine
starts and stops on a schedule controlled by the building automation system or
a simple time clock. The only daily maintenance requirement is to check the
operating log.
Water chillers are designed for maximum reliability with a minimum amount of
maintenance. Like all large mechanical systems, however, certain routine
maintenance procedures are either required or recommended.
