How do Industrial Refrigerant Chillers Work?

How do Industrial Refigerant Chillers work?

A refrigerant cooling system is a closed loop system which contains a refrigerant gas. This gas is compressed and pressurised through a compressor and cooled through a heat exchanger and fan arrangement to produce a high pressure, liquid refrigerant.

This liquid refrigerant then passes through a hot gas expansion unit, where it is allowed to expand and ‘evaporate’ back into a low pressure gaseous refrigerant. The change of state from a liquid to a gas draws heat from the surrounding area. This is normally carried out within a high conductivity heat exchanger allowing it to draw and remove heat from the liquid or air that needs cooling.

The gas then re-enters the compressor and the process is repeated. As such electrical energy put into the compressor pump can be used to produce a cooling or chilling effect.

Key components;

  • Compressor: Produces high pressure gas
  • Condenser: Liquefies and cools the refrigerant by passing it through a heat exchanger
  • Expansion valve: Controls the flow of the liquid refrigerant to the evaporator.
  • Evaporator: Allows the refrigerant to turn back into a gas, whilst using the drop in temperature to remove heat from the external processes which require cooling

Riley stocks a range of chillers for process cooling, usually liquids, at a range of capacities.
