What is a refrigerator? It is a device or a container that has existed in the lives of all people on the planet since long ago, although this container has progressed over time and has been created in various forms of modernity. A refrigerator is a cooling and keeping device for food and drinks. This device includes a cooler and thermal insulation, which includes the process of transferring heat from the interior to the exterior.
If you wet your hand, you will notice that you will cool down after a few minutes. This coolness is caused by the evaporation of water because it uses body heat for evaporation. The refrigerator also has a similar process. The refrigerator includes two processes of evaporation and condensation, which transfer heat from the interior to the exterior.
What was the method of storing food in the past? In ancient times, due to the lack of technology, people used springs, wells and underground caves to store food. They put it in a package and put it in the spring under the shade, so they could store food.
The history of refrigerator discovery: It is important to know that the famous Iranian scientist Ibn Sina invented the refrigerant in the 11th century AD, which sparked the creation of the refrigerator and created a big step in this process.
The first refrigerator in the world: The first refrigerator in the world was invented by William Cullen in 1748 and this project was exhibited at the University of Glasgow. The refrigerator that was produced was very efficient and had positive results by conducting various tests and advancing technology, an American scientist In the name of Oliver Evans, he invented a refrigerator that was much more modern than the original type, that’s why he was called the father of the compact refrigerator.
During the passage of time, many refrigerators were built with passage of time and different designs. Finally, over time, in 1853, the first refrigerator was invented, which was able to produce about one ton of ice per day, and it was registered in the name of an American scientist. Over time, with the advancement of technology, there have been huge changes in the production of refrigerators. We have provided you with a history of how the refrigerator was created, now we are going to provide you with information about the working process of the refrigerator.
The refrigerator has parts that are very necessary for the work process, in fact it is like a cycle, and in the absence of any of them, the process will be disrupted. These parts include:
- Compressor
- condenser
- operator
- Thermostat
- Refrigerator gas
Compressor: Sometimes you may have looked at the back of the refrigerator and seen the black box. You must have asked many times what this box is. It is the compressor or the refrigerator motor, which in home refrigerators includes two mechanical and electrical parts, and both The part inside the black box was placed. The electric part of the compressor is actually an asynchronous electric motor and it is responsible for moving the mechanical part, and the mechanical part of the compressor in the refrigerator consists of a cylinder whose piston is moved by the core of the electric motor, the reciprocating movement of the piston causes It creates suction and blowing, which ultimately requires cooling to continue the work process.
Evaporator: By moving the gas inside the evaporator, the compressor cools the evaporator and thus it cools.
Condenser: It heats up when the compressor starts working, and then the function of the condenser is to cool the gas discharged from the compressor and reduce the temperature of the compressor.
These capillary tubes are responsible for the most important task, which causes the refrigeration cycle and brings the Pharaoh gas to the boiling point.
What is refrigeration? The process of absorbing heat from one fluid to another, which includes air or water.
Refrigerant gas: In the early refrigerators, ammonia gas was used in the refrigerator, since this gas is harmful to human health, it was gradually replaced by Pharaoh gas, and nowadays Pharaoh 12 gas is used in refrigerators, which is completely odorless and It does not cause metal corrosion in a wet environment.
The remarkable thing is that it is not flammable and even in case of leakage, it is not flammable. However, with these advantages, Pharaoh gas has disadvantages, which include destroying the ozone layer, creating a greenhouse effect, and consuming more than ammonia gas, and also It has a high price and low efficiency.
How does an industrial refrigerator work? Due to the large size and volume of the food capacity, the industrial refrigerator receives heat in a large area and transfers the temperature from the inside to the outside with the help of a strong cooling system. These devices consume more energy than the domestic model. . In these refrigerators, parts such as evaporator and anti-mildew cooling fans are designed with high efficiency. It is worth noting that this device is bigger than the domestic type.
Store industrial refrigerators, horizontal freezers, standing freezers, 4-door and 3-door refrigerators, standing refrigerators, chests, and air curtains are made with today’s and modern standards.
Industrial refrigerators are divided into two general categories. Industrial refrigerators (box) and standing industrial refrigerators (vertical).
Boxed industrial refrigerators: This model of refrigerators is very practical due to the limited space and optimizing the space. The door material of these industrial cabinet refrigerators is glass or steel, and they are often prepared as 2 doors, 4 doors, and 4 drawers. It can be prepared according to the required space of the kitchen, restaurant or coffee shop.
Standing industrial refrigerator: This model of refrigerators is available in different sizes and types and is available in single door, two door, and three door types. It is used for selling sweets. The door material is this
Refrigerators are made of stainless steel or glass doors.
The refrigerator with a stainless door has been anti-impact due to its high resistance and can be used for a long time and is very welcome. But in the glass door model, it allows customers to easily see inside the refrigerator and view their items without opening the door, which in turn has been extremely well received.
