These units typically use a large-scale refrigeration rack system with a different setup than your home kitchen refrigerator. Here are some energy-saving tips to help your fridge do its job right. A little knowledge and TLC can help you understand what your refrigerator needs to function at peak efficiency for your household.
And when you have the facts about how a refrigerator works, you can feel empowered to do a bit of DIY refrigerator repair. You may need to contact a trusted refrigerator repair professional to make a repair or to detect a problem with your refrigerator. Our home service plans will not only protect your refrigerator but also many other appliances you use every day , such as your dishwasher, clothes washer and dryer, garbage disposal, oven, and more.
Your smoke detector is one of the most important devices in your home. In order for these tiny devices to do their jobs, though, they need some very basic routine maintenance. Find out what you need to know about checking your smoke detectors. According to Consumer Reports, here are some of the most common appliance problems and repairs with data to support the results. Have you ever opened your freezer to find everything inside covered in ice?
That's freezer frost, and can lead to multiple issues. Follow these tips to prevent freezer frost. In the first stage of the refrigeration cycle, refrigerant enters a compressor as a low-pressure vapor. The compressor compresses the refrigerant to a high-pressure vapor, causing it to become superheated.
Once the refrigerant is compressed and heated, it leaves the compressor and enters the next stage of the cycle. TIP: There are several styles of compressors that can be used in the refrigeration cycle, including scroll, screw, centrifugal, or reciprocating compressors. Stage 2: Condensation. After leaving the compressor, the hot vapor refrigerant enters the next stage of the cycle, condensation. During the condensation stage, the refrigerant enters a condenser and flows through a series of S-shaped tubes.
As the hot vapor flows through the condenser, cool air is blown across the tubes by a fan. The alcohol evaporates by absorbing heat from the surface of your skin, making your skin cooler. This is what refrigerant does, explained in detail below. The main components of your refrigerator are the following: compressor, condenser, evaporator, expansion valve, and the thermostat.
Here is what each one does:. This unit is responsible for the circulation of refrigerant throughout the system. It is both a pump and a motor. Located on the back outside wall of the fridge, it helps release the heat absorbed from inside the unit. Housed on the inside of your refrigerator, it absorbs any heat stored within the unit. This is what reduces the temperature. Refrigerant warmed by the inside of the fridge is carried through tubing which works as an expansion device as it cools the gas back into liquid.
Well, that is how it should work. Facebook icon. The load, in this case, are the products that need cooling in the refrigerator. The evaporator absorbs heat inside the refrigerator. It acts as a medium of exchange for heat from the stored products load to the refrigerant. In most cases, the evaporator is the coldest part of the fridge or the freezer. Here, the refrigerant is cold and moves at a slower pace in order to absorb as much heat as possible from the load. As it absorbs the heat, it gets hotter and turns into a gas.
By vaporising the refrigerant more heat is absorbed from the load. The refrigerant, now hot and in gaseous form, is then pushed back into the compressor. The refrigeration cycle starts and ends with the compressor. The refrigerant flows into the Compressor where it is compressed and pressurised. At this point, the refrigerant is a hot gas. The refrigerant is then pushed to the Condenser which turns the vapour into liquid and absorbs some of the heat.
The refrigerant then proceeds to the Expansion Valve where it expands, losing pressure and heat. The refrigerant coming out of the expansion valve is cold and slow due to the loss of pressure. It enters the Evaporator in a liquid state where the exchange of heat takes place thus cooling the load inside the refrigerator. As the gas cools down the load, it absorbs the heat which turns it into a gas.
The gas is then pushed back into the Compressor where it can start the cycle again. During the refrigeration cycle, a build-up of ice around the evaporator may occur. Both commercial fridges and freezers will combat this build-up with some form of defrost system.
