However, these early refrigerating machines were not widely adopted in kitchens.
3. The First Commercial Refrigerators
Commercial refrigeration began to take off in the 1850s with the proliferation of breweries and meat-packing plants. Thomas Midgley and Albert Marsh contributed to the development of more efficient refrigerants, including ammonia and sulfur dioxide, which were used in early commercial machines.
4. The Home Refrigeration Revolution
Refrigerators for home use started to appear in the early 1900s. The first household refrigerator, the Servel, debuted in 1913 and was known for using gas instead of electricity. Electric refrigerators followed quickly, with companies like General Electric and Frigidaire introducing models to the market in the 1920s and 30s.
5. Modern Refrigeration
The mid-20th century saw several improvements, including more compact designs, increased energy efficiency, and the use of safer refrigerants. These developments mirrored changes in consumer demands for convenience and energy efficiency. Refrigerators became a staple in every kitchen, changing how families planned their meals and shop for groceries.
