Procedure for Operation of Brine Chiller

Preparation of Brine Solution.

  • Brine Solution Preparation for Initial Makeup.
    • Prepare the solution as per ratio of 30% propylene glycol with soft water for the temperature of      the solution at 2.0–8.0ºC.
    • Close the outlet valve of the brine preparation tank and put the 30 Ltr of propylene glycol in the brine preparation tank and then makeup the tank upto 70 Ltr. with softwater with the help of bucket.
    • After preparation of solution, open the outlet valve of the brine preparation tank and makeup the   brine in the brine solution tank of the Brine chiller.
    • Repeat the step and till the brine solution tank filled.

  • Note:    
    • User department person will initiate the brine chiller operation intimation memo (Format No. (SOP/EN/XXXYYY) to BMS operator/shift in charge to start and stop the brine chiller.
  • Starting Procedure.
    • Check the brine solution level in the brine solution tank.
    • Check the availability of the power supply.
    • Open the valve of supply pump and recirculation pump.
    • Set the temperature of the chiller as per production requirement but not less than 0ºC.
    • Before switching on the cooling tower pump check level of water at cooling tower sump.
    • Start the cooling tower fan, cooling tower pump, chilled water supply pump and chilled water   Recirculation pump.
    • Start the compressor.
    • Check the status in the chiller display and ensure that “UNIT IS LOADED” and cool mode is on.
    • Check the status of the chiller at input M-14 selection display.
    • Record chilled water in and water out temperature at input M-1 and M-2.
    • Record suction pressure and discharge pressure at input M-3 and M-4.
    • Record suction temperature and discharge temperature at input M-5 and M-6.
    • Record the load current value at input M-12.
Preventive Maintenance of Cooling Towers
  • Stopping Procedure.
    • BMS operator/Shift in charge shall inform the HVAC operator/technician to stop the chiller.      as per the Brine chiller operation intimation memo.
    • Stop the compressor from selector switch.
    • After minimum 3 minutes stop the cooling tower fan, cooling tower pump, chilled water supply  
    • Pump and chilled water recirculation pump.
    • Close the valve of supply pump and recirculation pump.
    • Check the status of the chiller at input M-14.
    •     SOP        –  Standard Operating Procedure
    •     HVAC     –  Heating ventilation and Air conditioning.
