Application and benefit
  • Storage of refrigeration capacity with crushed ice
  • Increasing of top peak cooling power with smaller refrigeration machine
  • Reduction of peaks in electricity consumption
  • Additional use as direct chiller to allow lower energy costs

Efficiency of Making Ice:

The efficiency of the dynamic ice making with hot gas melting is based on the prevention of a thick ice shell on the evaporator, which causes a big resistance for heat conductivity at static systems with a thick ice layer.

Efficiency of Direct Chilling:

The evaporator can be free of ice at any time after thawing and therefore can be used as a direct chiller for the warm return water. Direct chilling on the iceless evaporator allows a much higher evaporation temperature, a higher COP of the refrigerant compressor and thus less electricity costs.

The direct chilling is recommended to be used as long as possible for the ground load. The mode can be switched automatically as a function of the return water temperature.

Method of Operation Making Ice:

Ice is frozen on vertical evaporator panels and forms a 6 – 8 mm thin layer of ice, which keeps the resistance of heat conductivity always at a low level. After some minutes of building up ice, an automatic plc system will give a signal for hot gas injection to the heat exchange panel for some seconds in order to split off the ice. Afterwards the evaporator is free again to form ice in an efficient thin layer.
