  • Issue Possible Cause Solution

    Chiller not starting Phase error / Low voltage Check wiring and voltage

    Low cooling Clogged condenser / low gas Clean condenser / top-up refrigerant

    High pressure trip Fan not running / high ambient Inspect fan motor improve ventilation

    Water flow alarm  Air lock / pump issue Bleed line, check pump impeller

    Ice formation Low water flow / setpoint too low Increase water flow / adjust setpoint

Working Principle of Air Cooled Scroll Chiller

An Air Cooled Scroll Chiller works by absorbing heat from a process or space and releasing it into the air using fans and a refrigerant cycle.

  • Compresses low-pressure refrigerant vapor into high-pressure, high-temperature gas.
  • Scroll compressors operate quietly and with fewer moving parts.
  • Condenser (Air Cooled Finned Coil):
  • Ambient air blown over the coil by fans cools the refrigerant.
  • The refrigerant gas condenses into high-pressure liquid.
  • Expansion Valve (TXV or Capillary):
  • Reduces the pressure of liquid refrigerant.
  • Converts it into a low-pressure, low-temperature mixture.
  • Evaporator (SS Coil/Shell & Tube/PHE):
  • The refrigerant evaporates by absorbing heat from process water.
  • The water is cooled down to the desired temperature.
  • Chilled Water Circuit:
  • Chilled water is pumped from the evaporator to the application (mould, tank, coil).
  • After absorbing heat, it returns to the chiller for recirculation.

Key Components Overview:

  • Component Function
  • Scroll Compressor Compresses refrigerant vapor
  • Air Cooled Condenser Removes heat from refrigerant
  • Expansion Valve Controls refrigerant flow and pressure
  • Evaporator Transfers heat from water to refrigerant
  • Fan (Blower) Pulls ambient air over condenser
  • Pump (Optional) Circulates chilled water to user point
  • Controller Regulates temperature and system safety
