The history of refrigerators

  1. 1. The history of refrigerators
  2. 2. The early fridge <ul><li>A hole dug into the ground which was cooler than the surrounding area which protected food that much more. </li></ul>
  3. 3. <ul><li>Then they created structures like these to store ice cut from frozen ponds from the warmer air. The shape and design would change from climate/geography or the culture that built it. </li></ul>
  4. 4. The first modern fridge <ul><li>In the 1748 the first known artificial refrigeration was designed and shown. By Oliver Evans </li></ul><ul><li>The first device able to </li></ul><ul><li>make 1 ton of ice was in </li></ul><ul><li>1853 </li></ul>
  5. 5. <ul><li>In 1913 fridges for home and domestic use where invented by Fred W. Wolf it later became the base for another. </li></ul><ul><li>Then in 1916 Alfred Mellows who’s idea was bought by William C. Durant to make the first mass-production of fridges. </li></ul><ul><li>In 1918 the first fridge with any type of automatic temperature control was invented. </li></ul>
  6. 6. <ul><li>Carl Von Linde was the first to patent and make a practical and compact refrigerator. </li></ul><ul><li>These home units usually required the installation of the mechanical parts, motor and compressor, in the basement or an adjacent room while the cold box was located in the kitchen. </li></ul>
  7. 7. <ul><li>Also in 1923 Frigidaire (a company) introduced the first self-contained unit. About this same time porcelain-covered metal cabinets began to appear. Ice cube trays were introduced more and more during the 1920s; up to this time freezing was not an auxiliary function of the modern refrigerator. </li></ul><ul><li>The first refrigerator to see widespread use was the General Electric &quot;Monitor-Top&quot; refrigerator introduced in 1927 nicked named after the monitor like top of the USS Monitor  </li></ul>
  8. 8. <ul><li>The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s and provided a safer, low-toxicity alternative to previously used refrigerants. </li></ul><ul><li>he 1950s and 1960s saw technical advances like automatic defrosting and automatic ice making. More efficient refrigerators were developed in the 1970s and 1980s, even though environmental issues led to the banning of very effective (Freon) refrigerants. </li></ul>
  9. 9. Over the years the fridge has changed to the way it is today
