How do Refrigerators Work?


Refrigerators can be such interesting appliances. Well, maybe interesting should be swapped for confusing. Refrigerators keep your food cold, but how? It can’t be just from being plugged in. Checkout below for how refrigerators, and their parts, work together to keep your food cold.

Within the refrigeration cycle, there are five main elements to be aware of. There is fluid refrigerant ( a compressor which manages the circulation of refrigerant), the condenser coils (found on the outside of the fridge), the evaporator coils ( placed inside the fridge), and an expansion device. The way they work together is fairly simple.

The fluid refrigerant compressor limits the vapor from the refrigerant which raises the pressure and propels it into the condenser coils on the outside of the fridge. When the warmer gas in the coils interacts with the cooler air of kitchen, it transforms into a liquid. With the liquid form at high pressure, the refrigerant cools down as it circulates through the coils in the fridge and freezer.

The refrigerant now soaks up the heat within the fridge cooling down the air. Lastly, the refrigerant evaporates into a gas, then circulates back into the compressor and begins again.

What an exciting adventure!
