12 Fundamental Parts of Refrigerator: Names, Function & Diagram

A refrigerator is a thermally insulated box that helps to transfer inside heat to the outside environment to maintain the inside temperature below room temperature. It is the assembly of various parts. Each part of the refrigerator has its function. When we connect them, we get the refrigeration system, which helps to cool the foods. Other parts of the refrigerator help to build its outer body. It provides a good shape and various compartments to store the different foods, fruits, and vegetables. We get to know the importance of refrigerators in the summer season. Information about parts of a refrigerator is necessary while buying a new refrigerator or during its maintenance. So in this article, we will see refrigerator anatomy, its components, names & functions.

Parts of a Refrigerator and their Functions


The function of the compressor is to compress the vapor refrigerant that comes from the evaporator and increase its pressure and temperature to atmospheric.

For the refrigerator, hermetically sealed compressors are the first choice.


When the vapor refrigerant comes from the compressor to the condenser coil, it initiates rejecting heat. Due to that, vapor refrigerant starts converting into liquid refrigerant.

Till the end of the condenser coil, refrigerant comes into liquid form. But this liquid refrigerant has a high temperature. It uses fans and fins for this conversion.

Expansion Valve

When the liquid refrigerant comes into the expansion valve from the condenser coil, it decreases the pressure and temperature of the refrigerant. It is placed before the evaporator.


In the evaporator coil, the refrigerant temperature is lesser than the room temperature. When this refrigerant passes through the evaporator coil, it absorbs the surrounding heat.

Due to that, the refrigerant temperature starts increasing, and it starts becoming vapor. At the same time, due to heat absorption, the nearby environment of the evaporator coil becomes cold.

Freezer Compartment

The freezer compartment is the top case part of the refrigerator that cools any product and helps to make ice. It is better to store ice-creams, Paneer, Butter, and Cheese and makes ice cubes. It has a separate door to open & close.

Meat Compartment

It stores meat products and acts as a deep freezer. It helps to keep meat for a prolonged period.


There is various storage available in the refrigerator. It helps to keep and store many products to keep them healthy.

  • Milk Product Storage- It store butter, cheese, curd, milk, and other milk products.
  • Sensitive Product Storage- It stores products like honey, ketchup, jams, and more.
  • Cool Drink Storage- It stores various types of cold drinks and beverages.
  • Bottle Storage- It helps to store cold water in the bottles.
  • Egg Tray- it stores the eggs in the trays.

Thermostat Control

It is a controller of the refrigerator. We can adjust the temperature inside the refrigerator with this controller.


These are the various compartments inside the refrigerator. It helps to divide the space inside it. So we can place many things as per our comfort.


It is a drawer or box on the lower side of the refrigerator. It is for storing fruits and vegetables. In this crisper fruits and vegetables last for a lengthier period.


There are two types of doors. The top door is the door of the deep freezer, and the lower door is the lower part of the refrigerator.

Magnetic Gasket

It is an air-tight magnetic sealing of the door. When we close the door, it creates air-tight sealing and prevents leakage. It has a magnetic property to maintain air-tight sealing.
