Abstract

In a freezer cabinet with cooled surfaces in a freezing chamber for storing of food frost appears on the surfaces and on the food. On defrosting the chamber has to be emptied of food and be heated so that the frost melts. Water is formed which has to be collected. The invention relates to a freezer cabinet operating without frost. An arrangement according to the invention is characterized by a circulation path (32,40) for air including a moisture-absorbing means and a motor-driven fan (38).
