Which Evaporator Is Used In Domestic Refrigerator?

What is the evaporator in a refrigerator?

The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold.

As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food..

What is domestic refrigeration system?

A domestic refrigerator is essentially a small cold storage where several food products such as ice cream, meat, fish, milk, fruits, vegetables, water etc. … The condenser of small refrigerators are of natural convection type, while larger refrigerators may have a fan for forced air circulation over the condenser.

How much refrigerant goes in a refrigerator?

Refrigerant Charge This amount is normally found on the model plate or manufacturer’s label, and it is measured in grams or ounces. The amount ranges from less than 1 ounce in small refrigerators to more than 6 ounces, or from 28.35 grams to about 185 grams.

Should refrigerator fan run all the time?

In order to produce cold air, your refrigerator depends on a condenser fan that draws in air over the condenser coils. … The refrigerator will have to run almost constantly in order to make up for the fan not working anymore. The small bit of good news is that this fan motor is pretty easy to test.

Where is the plate type evaporators used?

Plate types of evaporators provide excellent shelves in the freezers and similar applications. They can be used as the as the partitions in the freezers, frozen food display cases, ice cream cabinets, soda fountains and others.

Where is the evaporator in a refrigerator?

Why is evaporator used?

An evaporator is a device in a process used to turn the liquid form of a chemical substance such as water into its gaseous-form/vapor. The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process.

What type of freon does a refrigerator use?

R-134aRefrigerators manufactured from 1995 to the present typically use R-134a, an HFC, as a refrigerant. Both refrigerators and automobiles use R-134a as a refrigerant, and adults can buy it at most automobile parts stores. Combining the noncompatible refrigerants R-12 and R134a will lock up the compressor.

Does evaporator fan run all the time?

Good luck. The evaporator fan motor should run anytime the compressor and condenser fan motor are running. The evaporator circulates the air in the freezer and into the refrigerator section.

Why is ammonia used in food refrigeration?

In refrigeration systems, the liquid is stored in closed containers under pressure. When the pressure is released, the liquid evaporates rapidly, generally forming an invisible vapor or gas. … This is why ammonia is used in refrigeration systems. Liquid anhydrous ammonia weighs less than water.

Which gas is used in AC and refrigerator?

Thomas Midgley, Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12), in 1928. The name is a trademark name owned by DuPont for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant.

What happens if evaporator fan stops working?

Feel for cold air in the freezer. If the evaporator fan motor stops working, your freezer will begin to defrost. … Most freezers don’t run the evaporator fan motor when the door is open, so if the fan does work, it will turn off when you open the door. Check the temperature setting on the freezer to be sure it’s on cold.

What is the most common refrigerant used in household refrigerators?

HFC-134aModern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, instead of Freon. A R-134a is now becoming very uncommon in Europe. Newer refrigerants are being used instead.

What are the four stages of refrigeration?

The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components and is contained in the refrigerant loop. The refrigerant begins as a cool vapor and heads to the first component: the compressor.

How does a domestic refrigerator work?

Actually, the domestic refrigerator is a heat pump which throws the heat of the foods or stuff to be cool to the atmosphere by taking the power of a compressor. … The same is done by the compressor in the domestic refrigerator. The domestic refrigerator works on ‘Vapor Compression Refrigeration Cycle (VCRC)’.

What are the types of condenser?

There are three types of condensers: air cooled, water cooled and evaporative. These have been described below.
