A fridge, or refrigerator, is a common household appliance that is used to keep food and drinks cold. Fridges work by using a cooling system to remove heat from the air inside the fridge and transfer it to the air outside the fridge. This process keeps the air inside the fridge at a lower temperature than the air outside, which in turn keeps the food and drinks inside the fridge cool and fresh.
The cooling system in a fridge typically consists of a compressor, a condenser, an evaporator, and a refrigerant. The compressor is a motorized pump that is used to compress the refrigerant, which is a special type of fluid that is used to transfer heat. The compressed refrigerant is then pumped through the condenser, which is a series of metal coils that are located on the back of the fridge. The condenser is designed to release the heat from the refrigerant, and it does this by releasing the heat into the air outside the fridge.
After the heat has been released from the refrigerant, the refrigerant is then pumped through the evaporator, which is a series of metal coils that are located inside the fridge. The evaporator is designed to absorb heat from the air inside the fridge, and it does this by allowing the refrigerant to evaporate inside the coils. As the refrigerant evaporates, it absorbs heat from the air, which causes the air inside the fridge to cool down.
Once the refrigerant has absorbed the heat from the air inside the fridge, it is then pumped back to the compressor, where the cycle begins again. This process is repeated over and over again, with the compressor, condenser, and evaporator working together to transfer heat from the air inside the fridge to the air outside the fridge, and to keep the air inside the fridge at a lower temperature than the air outside.
To defrost a fridge, you need to turn off the power to the fridge and remove all of the food and drinks from the fridge. Next, use a soft cloth or sponge to wipe away any ice or frost that has built up on the inside of the fridge. Once the ice and frost have been removed, use a mixture of warm water and dish soap to clean the inside of the fridge. Finally, turn the power back on and allow the fridge to cool down before putting the food and drinks back inside.
