In emergency in case chilled water system trips or fails, the stand by Direct expansion system will start, hence during critical time HVAC facility will not get effected.
HVAC SYSTEM COMMISSIONING-)Informative Note
A)HVAC-Chilled water system-Commissioning-Entire chilled water pipes are clean flushed for 2-3- hours with plane water with the help of pump, to remove foreign particles, dust debris formed during welding(Pipes).First chemical is added- DEARBONE in to the closed chilled water pipe loop, system pressure is increased to 2-3 BAR with hand pump, run the system for 10-12 hours with continues water circulation with pump as desired by the consultant. Flush entire system, add chemicals(cleaning),inside water circulation check water sample in laboratory for PH value should be between 7-8.Seprate temporary Pump, Butterfly valve funnel assembly is made for this purpose. During flushing care should be taken that water should not enter chilled water coil in order to prevent any damage to coil. Check alignment of pulley for AHU Blower, fixing of Pre and Bag filters, Temperature and RH measurement , CFM fresh/recirculation air measurement etc.
Organize site visits when required, Site walk down, Preparing Punch list/Check list-Preparation of Mechanical Completion Packaged-MCP Documentation-HVAC System Commissioning, HVAC Run/Performance Test (Summer/Winter)/Compliance Report as per Client Documents requirements/System Hand Over/Client HVAC hand over.
