Answer 1

A pump compresses a gas into a liquid. The gas/liquid gets hot and the back of your refrigerator has a coil that lets some of the heat off before the liquor goes inside the refrigerator. Inside, the liquid goes through a restriction that turns the high pressure liquid into a low pressure liquid. Due to pressure change, the liquid absorbs heat. There is another coil on the inside that let’s the low pressure liquid evaporate into a gas all while absorbing heat. Then it flows back to the compressor.
