How Your Refrigerator Works

April 4, 2018 Published by Leave your thoughts

Many households in the United States own a kitchen with large appliances, like refrigerators and freezers. These types of home cooling units are convenient not only because they are right there in your house, but because they are designed to preserve your food for longer. While you know that putting food in your refrigerator is the best defense against food spoilage, what you may not know is how a refrigerator keeps everything inside of it cold. Your refrigerator is an amazing piece of machinery, with liquids turning into gases and water turning into ice all in an effort to keep your food fresh.

Let’s find out from an experienced refrigerator repair service in Addison, TX the purpose of refrigeration and how your refrigerator works.

Why foods need refrigeration

You know that some foods need to be stored in cold temperatures to help food stay fresh and to prevent spoilage, which is why you have a refrigerator in your house. All foods contain bacteria and will eventually spoil, but proper refrigeration slows down the activity of bacteria, meaning that the breakdown process takes longer. In the United States, the most common ways to preserve perishable foods—like meat, eggs, dairy and vegetables—is through refrigeration and freezing. Since spoiled food is a health hazard, you should maintain and service your refrigerator regularly.

How your refrigerator works

The exterior cabinet housing your home refrigeration unit is always in sight, but what is happening on the inside during the cooling process? The refrigeration cycle has five basic components: fluid refrigerant, a compressor (which controls the flow of refrigerant), evaporator coils (located inside of the unit), condenser coils (located outside of the unit) and an expansion device that all work together to cool your food. If you’ve ever wondered what goes on inside your refrigerator on a daily basis, read on!

  • The job of the compressor is to constrict the refrigerant vapor (the coolant), raise its pressure and temperature, and then push it into the coils on the outside of the fridge. The coolant is now a hot, high-pressure gas.
  • The hot gas in the condenser coils will soon meet the cooler air temperature of your kitchen, at which time it becomes a liquid.
  • Although the liquid is now in the outside coils, it will end up inside the refrigerator cooler and cabinet. In other words, it’s in liquid form at high pressure right now, but the refrigerant will cool down as it moves into the coils inside the fridge and freezer.
  • The cool refrigerant has an important job, which is to absorb the heat that’s inside the refrigerator. This process is what cools down the air in the cabin.
  • Finally, the refrigerant evaporates to a gas before flowing back to the compressor, at which point the cycle start all over again.
