    H8-420-03-01Ä General NO FROST appliances The need to supply consumer appliances which fulfil the requirements of the most modern criteria in food storage and which make optimum use of the available space has led to the development of the NO FROST refrigeration and freezing technology.

  • Page 6: Methods Of Refrigeration

    H8-420-03-01Ä Methods of refrigeration At Küppersbusch we distinguish between 3 types of refrigeration: Static refrigeration Refrigeration by means of an evaporator, where the air flow factor is not increased by the auxiliary device. With static refrigeration we depend on the normal circulation of air inside the appliance. Dynamic refrigeration The air is moved around the refrigeration cavity by means of a ventilator.

  • Page 7: No Frost Fridge-Freezers

    H8-420-03-01Ä NO FROST fridge-freezers With NO FROST appliances we distinguish between models with only one compressor and models with separate cooling circuits which have two compressors. All NO FROST appliances with a refrigeration unit belonging to the Küppersbusch family of domestic appliances are characterised by the same thermo-dynamic design.
  • Page 8 H8-420-03-01Ä In addition to the NO FROST fridge-freezer appliances with one cooling unit, KÜPPERSBUSCH also manufactures models with two compressors. These are appliances with a capacity of 300 l and with 3 or 5 doors. These models have two different cooling circuits. The refrigerator section operates by means of cyclical cooling with one cooling unit and separate temperature adjustment.

  • Page 9: Installation And Connection

    H8-420-03-01Ä Installation and connection Dry, well ventilated rooms present the best conditions for installing the fridge-freezers. In order to keep electricity consumption low, the appliances should not be installed next to a cooker or a radiator. Avoid direct sunlight. When installed in a kitchen, fridge-freezers are arranged to fit in with normal work routines. It must be ensured that the direction in which the door opens is the right one for the type of work carried out in the kitchen.
