Good Practices
Design
Adopt the pump system design calculation and recommended outputs in accordance with ISO 13612-1. Specify the use of unplasticised PVC pipe for cold water services/industrial use in accordance with SS 141.
Provide flow meters for chilled/condenser water loops. Consider a chilled water leak detection system near sources of potential chilled water leak.
Construction
Ensure proper workmanship during pipe installation and testing, especially at joints. Perform proper insulation of chilled water pipes to avoid condensation. Use primary-only variable flow chilled water pumping systems in accordance with SS 564-1 or equivalent. Vulnerable areas — at joints of inlet/outlet & drainage, pumps, condenser, valves, and drainage.
