We all know that a refrigerator cool things but this is not the only thing that a refrigerator does. A refrigerator removes the heat from different things, making them cooler and sustainable for a longer period.
Now, you might be wondering how or from where the cold comes and make things cooler! The thing is when gas passes through a state of high-pressure to a state of low-pressure, the temperature of the gas drops to a significant level.
Did you understand what we just said about how a refrigerator works? Don’t worry if you don’t understand because we have got your back. In this post, we are going to explain how a refrigerator operates in the simplest form. So, let’s start reading and explore the working process of a refrigerator.
How does a refrigerator work?
A refrigerator comes with a compressor and a closed system of tubing, containing gas in it. This compressor pumps the refrigerant and compresses it for lowering temperature. Broadly speaking, the refrigerant first flows through the coils on the back. It also goes through an expansion valve into the freezer. When the refrigerant passes through the expansion valve, it will make the pressure to drop to a lower level. As a result, the temperature will drop as well.
Within the refrigerator, there is a fan that circulates air over the cool tubing. Along with it, the refrigerant absorbs the warm air from the freezer. You can think that the fan within the freezer is just blowing the cold air and pumping the air into the appliance but, the thing is the heat is pumped out.
Usually, the cold air comes from the freezer (in almost all types of the refrigerator). This cold air will go through the vents to the fridge. When the temperature rises to a certain level, a thermostat will activate the compressor to control the heat. Currently, new refrigerator models have a separate cooling coil for both the freezer and the fridge. In that case, there are two different types systems for temperature controls.
When the air cools within the refrigerator, the water in the air will condense. Later, this condensed water would freeze into frost. With that said, most of the newest models have a built-in and automatic defroster that prevents any buildup of frost within the refrigerator. A heating element controls the defroster with a timer and thermostat. There is a pan beneath all refrigerators where the melted frosts drained out and evaporated.
Top Refrigerator Tips and Advice
Here are the Dos and Don’ts that you should follow for using a refrigerator. We believe these tips will help you out in different circumstances –
- The standard temperature range for a refrigerator is around 36 36 degrees Fahrenheit and for the freezer, the range is in between o and 5 degrees.
- If you want to decrease your energy bill, buying a new model would be an ideal option.
- In every six months, you must clean the coils with a vacuum or duster. It will ensure efficiency and decrease the operating costs.
- When there is a power outage, the fridge can stay cold for around eight hours. The freezer will stay cold for 48 hours. In that case, opening the doors without legitimate reasons would not be a wise move.
- You should always defrost the manual defrost freezer while never chipping away the frost.
- If the fridge is full, it might become more efficient than a half empty one. However, don’t fill the fridge with unnecessary items.
- When moving and storage, you should always keep your refrigerator upright
- After moving, you have to wait 24 hours before plugging it in.
- You must keep at least two inches of air space in the fridge and six inches above it.
- Don’t overfill your refrigerator or it won’t cool as well.
- Never overfill the refrigerator with unnecessary items because it will not cool well.
- Never keep your fridge unplugged for an extended period as some units need continues connection for proper lubrication of the compressor.
- Never tip the refrigerator onto its side as the oil from the compressor could run up into the filter or dryer.
The bottom line is all refrigerators and freezers have an appropriate temperature level. If you keep them below that level (roughly 45 degrees), they won’t cool well. In that case, you should follow our above tips and maintain your refrigerator to the optimum level.
