History of Refrigerator
The first refrigeration machine was invented in the early 19th century by American inventor Oliver Evans. However, the modern refrigerator as we know it today was invented by a Scottish engineer named William Cullen in 1820. He demonstrated a refrigeration machine that used a vapor-compression cycle, which is still the basic principle used in most refrigerators today.
The first commercial refrigerators were manufactured in the late 19th century by companies such as General Electric, Westinghouse, and Kelvinator. These early refrigerators were large, bulky, and expensive, and were primarily used in commercial settings such as grocery stores and restaurants.
Over time, refrigerators became smaller, more efficient, and more affordable, making them a common appliance in households around the world. Today, refrigerators are an essential part of modern kitchens and come in a wide range of sizes, styles, and features to meet the needs of consumers.
