Long ago, people didn't have refrigerators. They kept food in cool places like caves.

In ancient times, people used underground chambers to store food. These chambers were called icehouses.

The first domestic refrigerator was invented in the mid-1800s. It used ice to keep food cold.

In 1913, refrigerators with an electric compressor were introduced. They didn't need ice anymore.

Over the years, refrigerators became more efficient and used safer coolants like Freon.

Today, refrigerators have many features like ice dispensers, temperature control, and even Wi-Fi!

Thanks to refrigerators, we can safely store food and keep it fresh for a longer time!

Now, go and appreciate your refrigerator, it's a cool invention!
