Mode of action

Chillers are complete compact refrigeration units for cooling of liquids in the circuit. In general, the liquid water or water with additives (glycol), which are designated as refrigeration carriers because of the function.

A chiller primarily consists of a hydraulic part and a refrigeration part.
By the hydraulic components, heat is transported from heat-producing devices or systems by the flow of refrigerant through the applications to be cooled.

In a chiller as cooling unit is the heat exchanger of the re-cooler a refrigerant evaporator. By this, temperatures between +5°C to +25°C can be achieved. In the course of the evaporation process of the liquid refrigerant the absorbed heat is dissipated by the condenser of the chiller (usually to the ambient air).

A cycle cooling is realized without the loss of refrigerant. The advantage of a chiller consists next to the water resource-saving feature that for the application to be cooled conditions are always constant.
