Fridge Mechanism
In this article, I am gonna talk about about the mechanism of a normal defrost fridge and no frost fridges. I am not going to differentiate it, because I’ve already told in my earlier article. Right here is am talking concerning the normal mechanism and the things which can be working in refrigeration in a fridge. This thing will probably be basic data for fridge restore.
Fridge compressor:
The most common factor that every person know about the fridge is it is compressor, this is the primary point of a fridge. Well it’s true, because compressor compress fuel, it suck and discharge the gas and make refrigeration in the fridge. Now let’s start understanding the compressor and it is components.
If we see in a compressor then we’ll find two working components, one is pump and other is stater, the work of stater is to rotate the pump and pump starts working and pressurize the fuel in the chamber and it returns within the suction line. It’s a small scenario of a compressor, there are two most common compressors are available, one is simple pump compressor and different is rotatory compressor. A rotatory compressor is in cylinder form entire a normal compressor is in round form.
If we see the compressor then we can see there are several pipes inside the compressor, but in actuality there are solely two major pipes that are working, one is suction pipe and other is discharge pipe, suction pipe sucks gas and discharge pipe discharges the fuel , if you see three pipes in your compressor then one is suction, second is discharge and third will be charging line that technician use to charge the fuel.
Fridge Condenser:
After compressor, the discharge pipe connects with the condenser that you can see behind the fridge, the black grill that becomes too hot whereas fridge is in working situation. This is because compressor pressurize the fuel and fuel turns into sizzling, after traveling into chamber, it comes inside a little strainer, this is a small tube with stain inside it, some strainers are bigger than normal and it has some round jelly balls inside, this type of strainer is called dryer, because it dries the fuel.
The opposite end of strainer, you can see a capillary tube, that is a skinny tube, that compress the fuel and this capillary spray the fuel inside the chamber of refrigerator. It continuously spray the fuel that was in liquid kind in the capillary, due to stress and compression. After traveling the whole refrigeration chamber it then travel within the lower chamber of fridge that we use for storage of our bottles and grocery etc.
Fridge Lower Chamber:
After completion of fuel travel within the lower chamber, it comes back within the compressor. On this whole process not solely discharge works but suction also work. If the compressor is sucking gas then it is discharging fuel in the outlet of the compressor. That is the whole cycle {that a} normal fridge has.
Extra pipes with compressor:
Now let’s speak about the different pipes. You can find them under the main pipes. There could be two additional pipes, because in regular fridges there are solely three pipes. If you see 5 then there will be two extra pipes for interior condenser. That is to extend the gap and the capacity of compressor. The gap of fuel journey is important for compression.
Fridge repair
A technician will face problem, if he is going to replace the compressor. Let’s suppose if there is a compressor of 1/2 horse energy and technician can’t find a new compressor of identical capacity? then he can use 3/4 HP compressor instead. However then he will need to shorten the distance of pipes to get correct cooling. Mostly technicians enhance or decrease the size of capillary to get results and they enhance the fuel too.
I hope that I’ve told all the mechanism that is being used in a normal fridge. The same system can also be applied in refrigerator too. Here I’m talking about normal fridges and fridge including deep freezer. The mechanism of air conditioner can also be same however the size of compressor is bigger than fridge and refrigerator. This is due to cooling capacity that we can measure in MMBTU.
