Two different modes of operation eventually prevailed in refrigeration appliances. So-called compressor refrigerators were and still are in most households. They have a high degree of efficiency and are therefore suitable for use in the home. Absorber refrigerators, on the other hand, operate completely without noise or vibration and are used especially in mobile homes or hotel rooms. At that time, the refrigerant used was ammonia, which was toxic, corrosive and foul-smelling. In the search for effective and less dangerous alternatives, chlorofluorocarbons (CFCs) were discovered and soon used en masse as refrigerants. | Two different modes of operation eventually prevailed in refrigeration appliances.

In the 1950s, the refrigerator began to make its way into German households. The economic miracle ensured lavishly laid tables. The newly won prosperity was to be preserved, but also presented. Electric household appliances were just as much symbols of prosperity as well-stocked pantries. Advertising was no longer merely about the "fight against spoilage," as it had been in 1936. The expectation was raised of being able to entertain guests with a sumptuous meal at any time.<ref>Buck, Susanne: Kühlschränke, S. 181-183.</ref> To do this, it needed more space for more food. Constructors and designers turned their attention to the interior of the appliances. For the first time in the 1950s, the refrigerator door was designed as an additional storage space. | |||

In 1967, Robert Bosch GmbH and Siemens AG merged their two household appliance divisions into a joint subsidiary, BSH. In order to exploit synergy effects as efficiently as possible, the manufacturing and sales structures of the two companies were streamlined and standardized. The former Bosch site in Giengen developed into a BSH site for refrigeration appliances. Refrigerators, freezers and refrigerator-freezer combinations of the Bosch and Siemens brands are still manufactured here today. In addition to the factory, a competence center dedicated to the research and development of refrigeration appliances was also established here.<ref>BSH Hausgeräte GmbH (Hrsg.): Der Standort Giengen – Innovative Kühltechnik für die ganze Welt.

In the mid-1960s, the design of refrigeration appliances became more and more similar to the rest of the kitchen. The sales argument as a prestige object fell away, and the original arguments - avoidance of food waste and improved quality of life - came to the fore again. Simply preserving food, however, was no longer enough. In the 1970s and 1980s, technologies such as special temperature and climate zones for different foods and 0° fresh storage emerged. At the same time, improved insulation made appliances increasingly energy efficient.<ref>Buck, Susanne: Kühlschränke, S. 181-182.</ref> | |||
