A double door refrigerator is one of the highest selling items available in the electronic market. Who in the world does not require a good quality proper functioning refrigerator! People who live in tropical areas like south Asian countries understand the value of a decent refrigerator. Have you ever mistakenly left the food out of the refrigerator for 4-5 hours? You know what happens after that. That food no longer remains in a consumable state. Therefore, it is a must to have a refrigerator that will fulfill the needs of you and your family.
People living in large families often go for two small/single door refrigerators. However, it will cost you more in purchase and repair as well. Considering to buy a good double door refrigerator is the best thing you can do for it. Before purchasing a double door refrigerator, you must know about its functioning and how it works. It will also help you to sort out minute problems without the help of a technician. Here is how a double door refrigerator works:
1. How does the refrigerator work?
The throttling device in the back of the refrigerator drops the pressure and temperature. The boiling point of the liquid is reduced, and thus the temperature drops. It transfers from the throttling device to the cooling rod. The heat exchange process occurs in the evaporator.
2. How does the auto defrosting work?
The timer present in the refrigerator determines the time of the defrosting. It heats the evaporator coil or cooling element present posteriorly to the refrigerator. The heating of the evaporator rod melts up the frost that is present in the fridge. The electric timer turns on the auto defrost for every 15- 30 minutes in interval or 8 to 24 hours. The compressor operates for the rest of the time for cooling to restore the cooling process. The defrost heater has a power ranging from 350 to 600 watts. It is prone to short circuits. Thus, the fusible link is installed near it to protect it from a short circuit. The auto defrosting mechanism turns on when the temperature drops to -5 and shuts off when it becomes positive.
3. How does the fridge unit work?
The condenser present in the back of the refrigerator plays the primary role here. Have you ever spilled the alcohol over your skin? How do you feel after it? Do you experience a chill sensation? It occurs due to the evaporation of liquid to the gaseous state. A similar process happens with the fundamental unit of the refrigerator too.
The compressor helps in retaining the liquid state from the gaseous by compressing it under higher pressure. It causes the temperature to rise, and the gas again turns to a liquid. To circulate cold air inside the primary unit, it needs to be in a gaseous state. Therefore, this liquid is passed via the condenser that cools it down. Additionally, the fan present in the refrigerator helps to circulate cold air to the primary unit.
We hope that you have a clear idea about all the components of a double door refrigerator, including the compressor, condenser, evaporator, capillary tube, and the thermostat. Thanks for reading!
