A refrigerator thermostat is an indispensable component within a refrigerator that controls its temperature and ensures optimal cooling. As the name suggests, it acts as a regulator that maintains the desired temperature, allowing the contents inside the refrigerator to stay fresh for extended periods. In this article, we will explore the structure and role of a refrigerator thermostat, understanding the science behind its operation and its significance in preserving food and other perishable items. Understanding the inner workings of a refrigerator thermostat will give us a deeper insight into one of the key components that make refrigeration technology so efficient and essential in our daily lives.
Refrigerator thermal relay is an important and indispensable component in protecting the refrigerator compressor, an effective tool to ensure stable operation of the equipment. In this article, Thptlaihoa.edu.vn will share with you what is a refrigerator thermostat? Structure and role of refrigerator thermostat!
What is a refrigerator thermostat?
Thermal relays are also known as thermal relays . This is a device that can automatically close and disconnect the circuit when the current shows signs of overload. These thermal relays work based on the expansion of metal rods when heated.
Structure of refrigerator thermostat
Refrigerator thermal relays usually have 2 types and different uses:
- Refrigerator thermal relay used to preserve food in the freezer compartment is a type with contacts used to switch on and off the compressor.
- Refrigerator thermal relay used to preserve food in the refrigerator compartment is the type with door to adjust the wind speed.
The structure of the thermostat of the refrigerator is quite simple, including:
- The temperature sensor contains a volatile medium to convert the cold chamber temperature signal into a pressure signal.
- The stacker helps to transmit the pressure signal to the mechanical expansion of the stacker by between the stacker and the ducted thermocouple.
- The lever mechanism will help turn the expansion of the folding box into a decisive contact closing action.
- The spring and screw system helps to adjust the temperature from the coldest mode to the coldest mode.
Working principle of refrigerator thermostat
The working principle of the refrigerator thermostat is quite simple. When the temperature in the refrigerator drops to the allowable level, causing the metal steel plate to expand unevenly, the pressure in the thermocouple and in the stacking box drops to the point that the flip mechanism flips downwards, disconnecting the top switch and circuit stops working.
When the contact surface temperature rises again below the safe level, the pressure in the stacker increases, the stack gradually expands. Then the metal plate reaches a flat state and the circuit closes.
The role of the refrigerator thermostat
Refrigerator thermal relay is used to protect the refrigerator compressor when When the electrical equipment shows signs of overload, sometimes the current is greater than the allowable level, sometimes it drops below the allowable level. Therefore, its main use is to be used to interrupt the circuit immediately when needed.
Refrigerator thermal relay has the role of helping the refrigerator operate more durable and stable, minimizing damage caused by the current falling into an unstable state during electricity use. Thermal relay is considered one of the most important devices in the refrigeration system.

In conclusion, a refrigerator thermostat plays a crucial role in maintaining the desired temperature within a refrigerator. It is a device that senses the temperature inside the refrigerator and controls the operation of the cooling system. The structure of a refrigerator thermostat typically consists of a temperature sensor, a control dial, and a switch. The temperature sensor monitors the temperature inside the refrigerator and relays the information to the control dial. The control dial allows users to set the desired temperature by adjusting it accordingly. The switch, on the other hand, activates or deactivates the cooling system based on the temperature sensed by the sensor. By continuously monitoring and adjusting the cooling system, the thermostat ensures that the internal temperature of the refrigerator remains at an optimal level for preserving food and preventing spoilage. Overall, the refrigerator thermostat is an essential component that plays a vital role in maintaining the functionality and efficiency of refrigerators.
