Understanding the Basics
A double door refrigerator, also known as a side-by-side refrigerator, is a popular choice for many households. It offers ample storage space and a convenient layout that allows easy access to both the fridge and freezer compartments.
The basic principle of a double door refrigerator is to maintain a cold environment inside the fridge to keep food fresh for a longer period of time. The refrigerator achieves this by controlling the temperature using a combination of mechanical and electrical components.
1. Compressor and Condenser
At the heart of the refrigeration system is the compressor. It is responsible for compressing the coolant or refrigerant, which is a chemical compound that absorbs heat from the fridge’s interior.
The compressed coolant then moves to the condenser, where it releases heat and transforms back into a liquid form. The condenser is located at the back or bottom of the refrigerator and is usually cooled by a fan or through natural convection.
2. Evaporator and Expansion Valve
After the refrigerant leaves the condenser, it enters the evaporator. The evaporator is located inside the fridge compartment and is responsible for absorbing heat from the internal air.
As the refrigerant absorbs heat, it evaporates and transforms into a gas. This process cools down the air inside the fridge. The cooled air is then circulated back into the refrigerator compartment.
The expansion valve controls the flow of the refrigerant between the evaporator and the condenser. It maintains the right pressure inside the system, allowing the refrigerant to change states at the right time.
In addition to these key components, a double door refrigerator also includes insulation material to prevent external heat from entering the fridge and a thermostat to control the temperature settings.
By understanding the basics of how a double door refrigerator works, you can appreciate the technology behind this essential household appliance. It’s a combination of mechanical engineering and thermodynamics that keeps your food fresh and your drinks cold.
The Principle of Cooling
A double door refrigerator uses a principle known as the refrigeration cycle to cool and maintain a cold temperature inside the appliance. This principle relies on the fact that when a liquid evaporates, it absorbs heat from its surroundings, resulting in a decrease in temperature.
The basic components involved in the refrigeration cycle are the compressor, condenser, expansion valve, and evaporator. The process starts with the compressor, which pressurizes the refrigerant gas. As the gas is compressed, its temperature increases.
Next, the high-pressure gas flows into the condenser, where it releases heat and condenses into a high-pressure liquid. The condenser is usually located at the back of the refrigerator and is responsible for removing heat from the system. This is why you may feel warm air coming from the back of the fridge.
The high-pressure liquid then passes through the expansion valve, which is a small opening that allows the refrigerant to expand rapidly. This expansion causes a drop in pressure and temperature inside the evaporator.
The evaporator is located inside the refrigerator and is responsible for absorbing the heat from the food and items stored inside. As the low-pressure liquid evaporates, it turns back into a gas and absorbs heat, thus cooling the surrounding air inside the refrigerator.
The cycle continues as the low-pressure gas returns to the compressor, and the process repeats. By continuously cycling the refrigerant through these components, a double door refrigerator is able to maintain a cold temperature inside the fridge compartment.
In addition to the refrigeration cycle, a double door refrigerator also has insulation to help keep the cold air inside and the warm air outside. The double doors and rubber gaskets around the edges create a seal, preventing cold air from escaping and warm air from entering.
This principle of cooling is what allows a double door refrigerator to effectively store and preserve food at low temperatures, keeping it fresh for longer periods of time.
Components and their Functions

Cooling Cycle
The cooling cycle in a double door refrigerator involves a series of processes that work together to maintain a cool temperature inside the appliance. Understanding how the cooling cycle works can help you make the most of your refrigerator and keep your food fresh for longer.
The cooling cycle begins with the compressor, which is responsible for compressing the refrigerant gas. This compressed gas flows into the condenser, a series of coils located on the back or bottom of the refrigerator. As the gas cools, it condenses into a liquid. The condenser fan helps dissipate the heat from the condenser, allowing the liquid refrigerant to cool even further.
Once the refrigerant has cooled down, it flows into the expansion valve. The expansion valve acts as a control point, regulating the flow of refrigerant into the evaporator. As the liquid refrigerant passes through the expansion valve, it experiences a drop in pressure. This pressure drop causes the refrigerant to evaporate and absorb heat from the air inside the refrigerator, thus cooling it down.
The evaporator is a set of coils located inside the refrigerator. As the refrigerant evaporates, it draws heat from the surrounding air, which causes the air inside the refrigerator to cool down. The cold air is then circulated throughout the refrigerator compartment by a fan, ensuring that all the contents are cooled uniformly.
Defrost Cycle
In addition to the cooling cycle, double door refrigerators also have a defrost cycle. The defrost cycle is necessary to prevent the buildup of ice on the evaporator coils, which can reduce the efficiency of the cooling process. The defrost cycle typically involves heating up the evaporator coils to melt any ice buildup, and then draining the melted water out of the refrigerator.
Temperature Control
Double door refrigerators usually have a temperature control feature that allows you to adjust the desired temperature inside the refrigerator. The temperature control regulates the operation of the compressor and other components of the cooling cycle to maintain the set temperature. It is important to set the temperature correctly to ensure that your food stays fresh and to minimize energy consumption.

It is typically located near the evaporator coil, which is responsible for cooling the air inside the refrigerator.
When the temperature inside the refrigerator rises above the desired level, the thermostat signals the compressor to turn on. The compressor then starts circulating refrigerant through the evaporator coil, which cools the air inside the refrigerator. As the air cools, it is circulated back into the main compartment of the refrigerator.
Once the air reaches the desired temperature, the thermostat signals the compressor to turn off. This cycle repeats as needed to maintain a consistent temperature inside the refrigerator.
In addition to the thermostat, there are other factors that can affect the temperature inside a double door refrigerator. These include the placement of items in the refrigerator, the frequency of door openings, and the ambient temperature of the room. It is important to avoid overcrowding the refrigerator and to ensure proper air circulation to maintain optimal temperature conditions.
